Title: Tying apparatus
Inventor: WALTERS JOHN WALTER GRAY
IPC: B65B13/10
Filed: 1962-08-27
Abstract: 1,048,681. Bundling machines. SHERIDAN SERVICE CO. Ltd. Aug. 26, 1963 [Aug. 27, 1962], No. 32810/62. Heading B8C. [Also in Division D1] Bundles Z enter a tying machine on a roller conveyer 22, are arrested at a first station by movable pillars 38 for transverse tying F, and are released and carried forward by the conveyer 22 until stopped by further pillars 62 a a station where a longitudinal tie G is applied before the bundles are discharged. The ties are effected without turning the articles. Adjustable guide plates 36 centre the bundles in the machine. As a bundle approaches the first tying station, it triggers a switch causing the conveyer 22 to halt and actuating pneumatically-operated pressure plates 24 to compress the bundle, which may be of newspapers. A further switch, operated by the plates 24, imparts drive to an annulus 4 carrying the end of the twine 16 gripped between a button 10 and a plate 12, the twine thereby encircling the bundle. Further mechanism (see Division D1) then tightens the twine, knots and cuts it before the drive to the conveyer 22 is re-engaged and the pillars 38 withdrawn. As the bundle approaches the second tying station it trips a switch to actuate further pressure plates 68 and disengage the conveyer 22. The same sequence of operations is carried out as at station one, the annulus 52 having an arm 56 extending over the path of the bundle to effect the longitudinal tie G. The pillars 68 are withdrawn and the bundle discharged on the conveyer 22. The pillars 38, 62 return to closed position after the release of the bundle from their respective stations. The button 10 picks up the free end of twine preparatory to tying the next bundle. The conveyer 22 may be formed in one or two groups. The pressure plates may be omitted from the cycle. Reference has been directed by the Comptroller to Specification 820,866.

Title: Improvements in or relating to thermionic amplifiers
IPC: H04N5/14
Filed: 1933-11-27
Abstract: 415,619. Valve circuits; synchronous movements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Bransom, H. ; 1313, Fillmore Street, Philadelphia, U.S.A.) Nov. 27, 1933, No. 33199. Convention date, Nov. 26, 1932. [Classes 40 (iii) and 40 (v).] Relates to a thermionic amplifier comprising means for abruptly altering the gain thereof and in which means are provided for cancelling out transient impulses due to said abrupt change in gain. The invention is described with reference to an amplifier carrying television &c. signals upon which are superimposed synchronizing impulses which may operate to change the amplifier condition from inoperativeness to operativeness and vice versa at rapidly recurring intervals. As shown, the television signals are fed to the control grid 3 of a screen grid valve 1 which is coupled to an output stage 21, in the anode circuit of which is a resistance 27 carrying the amplified signals. The valve 1 is normally paralyzed by a negative grid bias from a source 19 which is periodically neutralized for synchronizing purposes by the flow of plate current from a control valve 29, through a resistance 15 in the cathode circuit of valve 1, the valve 29 being controlled from a source 38 of synchronizing impulses. In order to neutralize transient impulses produced in the amplifier by the sudden changes in gain, a compensating valve 39 which is not fed with television signals but otherwise is arranged to produce the same transients as the valve 1, feeds said transients into the signal output circuit of valve 21 where they are developed across a resistance 49 in series with the resistance 27. The two sets of transient impulses are thus superposed in phase opposition and neuttralize each other in the output circuit.

Title: A method of and apparatus for heating a fluid by means of an auxiliary fluid at highpressure
IPC: H02K44/08
Filed: 1966-07-25
Abstract: 1,132,324. Heating by shock-waves. E. BROCHER. 25 July, 1966 [27 July, 1965], No. 33318/66. Heading F4U. [Also in Division H2] A high-pressure fluid and a fluid to be heated are alternately introduced into a shock tube, and the tube outlet is cyclically closed so that the latter fluid is heated by shock-wave compression. As shown, a first fluid from a reservoir 12 is compressed at 15, 16, 17, pre-heated at 8 and supplied to the shock tube 1 under the control of a rotary three-way distributer 2 which also receives a second fluid from reservoir 9 via pre-heater 8. In the shock tube the second fluid is heated sufficiently to cause ionization and to raise its electrical conductivity to at least 0À1 mho/m. and the heated fluid is then expanded at constant enthalpy by passage between short-circuited electrodes 22, 23 disposed parallel to a magnetic field B. The heated expanded fluid is returned to the shocktube for further heating via line 6 while the first fluid is returned to the compressor 15, 16, 17, separation of the fluids being effected by a rotary distributer 3. When the second fluid has attained a desired temperature the electrodes 22, 23 are connected to an external load so that the apparatus then functions as a magnetohydrodynamic generator. In a modification (Figs. 3 to 5, not shown), a plurality of shocktubes are arranged to form a drum which is rotated past fixed inlets and outlets for the fluids.

Title: Circuit arrangement for the identification, marking or supervision of lines in telecommunication systems, in particular in telephone systems
IPC: H04M15/08
Filed: 1957-10-25
Abstract: 829,249. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 25, 1957 [Oct. 31, 1956], No. 33388/57. Class 40 (4). In a circuit arrangement for the supervision or identification of lines, or for the marking of connecting elements allotted to the lines, the voltage supplied to the switching means which effects the supervision, identification, or marking changes abruptly when the current drawn by the switching means reaches a predetermined value. A starting and marking circuit MK for the finder switches AS, which may be cross-bar switches, is connected to individual subscriber's lines, such as T1n11, via semiconductor diodes, such as D11a, D11b and Dz11, Dell, which are backed off in known manner by the potential changes which take place on the a, b and c wires when a connection is set up through the finder stage AS. In the idle condition a current determined by the insulation resistance RJ flows in each subscriber's line via resistors such as R11a, R11b If U1 is - 60 v., U2 is - 30 v. and U3/U4 is - 47/- 40 v., the point P1 will have a potential of - 30 v. to - 39 v. for insulation resistances down to 20,000 ohms and the diodes Dz11 and De11 are backed off. If the insulation resistance of a line, say Tln11, decreases further, the potential at P1 becomes more negative until finally Dz11 and Dell become conductive, thus allowing the transistors Tz1 and Te1 in the circuit MK to conduct also. Collector current thereupon operates the tens relay Z1 and the units relay E1 relevant to the subscriber 11. This current is provided by the potential U3 (- 47 v.) supplied to point P2 by the supply device SPQ. If this potential were to remain constant, then only one marking relay, say Z1, might operate, so that the finder would not be started and the circuit MK would be out of service to other lines. To avoid this, the circuit SPQ is so designed that the potential supplied to P2 rises to - 40 v. (U4) when the current is of such a value that the most sensitive of the marking relays has just not responded, and remains at - 40 v. during further increases of current. Lock-out arrangements are provided to ensure that only one line can affect the circuit MK at any one time. Current supply equipment SPQ.-This consists of a voltage divider comprising resistors Wi1 to Wi4 connected in series between ground and a source of - 60 v. With no load current and for load currents lower than the predetermined value, P2 is at - 47 v. When the load current reaches that value the voltage drop across resistor Wi5 is so high that transistor Tsp1 conducts and its emitter-collector path shunts resistor Wi3 so that the potential at P2 rises to - 40 v.

Abstract: 643,525. Epicyclic gearing; gearing for stopping machinery. SOC. AUXILIAIRE D'INDUSTRIE SADI, S.P.R.L: Dec. 18, 1947, No. 33405. Convention date, July 17, 1946. [Classes 80(i) and 80(ii)] Reduction gearing between a driving motor and a driven apparatus such as a valve or sluice and comprising two epicyclic gears 2. 9, 7 and 8, 15, 13, Fig. 1, in series, has cam means whereby slip of a braked reaction annulus 15 on overload releases a positively held reaction annulus 9 having an abutment 12 whose consequent rotation operates a motor cut-out and a signalling device, (not shown). Means are provided to hold the braked annulus positively during initial movement of the driven apparatus so as to allow the temporary transmission of torques above the normal maximum. A driving sun 2 and the annulus 9 mesh planets 7 whose carrier 8 forms a second sun meshing with the annulus 15, planets 13 on a driven carrier 14. The annulus 9 is held by spring- loaded pawls 11A, 11B, Fig. 2, and the annulus 15 by a constantly-applied brake comprising a band 18 the opposed ends of which .are acted on by adjustably spring-pressed plungers. A cam 17 on the annulus 15 lifts the pawls 11A, 11B upon overload and allows the abutment 12 to operate. The driving shaft 1 is constantly operated on by one or more adjustably spring-loaded friction members 3 to prevent backward rotation of the shaft 1 when the motor cut-out is operative. A second set of teeth 15<SP>1</SP> on the annulus 15 have co-action with pawls 16A, 16B, Fig. 4, mounted on fixed pivots and having tails co-acting under spring- loading with a cam 21 journalled on the carrier 14. On initial operation of the driven apparatus in either direction, say clockwise as seen in Fig. 4, the appropriate pawl, 16A, is operative to hold the annulus 15 positively against anti-clockwise reactive rotation. The cam 21, which when otherwise free is driven from the cage 14 by spring-pressed friction pistons 22, is at this time held from rotation by a camended pin 23A co-acting with a fixed abutment 26, until a recess 27 in the carrier 14 passes under the pin and allows it to retract temporarily sufficiently to clear the abutment 26. The cam 21 is immediately arrested by a second similar pin 23B whilst the carrier 24 makes almost a further complete rotation, when the pin 23B is in turn released and the cam is free to turn until a shoulder 28 thereon meets the pawl 1GA which has by then been allowed by the cam to disengage from the teeth 15<SP>1</SP>, so that the annulus 15 is no longer positively held. More than one abutment 26 may be employed.

Title: Improvements in or relating to machines suitable for operating on shoes
IPC: A43D23/04
Filed: 1960-09-29
Abstract: 968,997. Shoe machinery. BRITISH UNITED SHOE MACHINERY CO. Ltd. Sept. 29, 1960 [Oct. 1, 1959], No. 33409/60. Heading A3B. A machine has instrumentalities for operating on a shoe in an automatic cycle, a support for a shoe on a last which moves lengthwise and heightwise of the shoe, and an abutment, against which heightwise pressure of the shoe causes the operation of the automatic cycle. A heel seat lasting machine is described by way of example. The machine has means such as a control member 182 (Fig. 1) which may be used to start the automatic cycle but which can also be operated automatically when the jack post 42 is pressed against the abutment 92. The jack and the control member are both preferably provided with power operated means for their movements and these means may be fluid pressure operated means. The fluid pressure means are brought into operation by means of a treadle, which, being attached to the lever 150 (Fig. 3), when depressed causes the pin 160 to depress the plunger 132 in the valve 130 thus admitting the fluid via the conduit 90 to the cylinder 74 to act on the piston 76 which acts through 70, 84, 66 &c., on the jack causing it to pivot about the pin 41 and thus move the shoes lengthwise to press it against the heel band 10, and heightwise to press it against the abutment 92. Check and throttle valves 166 and 168 are employed to control the speed of movement of the jack in both directions. Depression of the treadle also causes a pin 216 to depress the plunger 208 in the valve 210 and thus admit fluid via the conduit 204 to the valve 202. The jack post is in two parts; a post 42 mounted for vertical movement in the part 44, a spring 54 permitting relative movement of the two parts. The valve 202 is attached to the part 44, and a pin 216 is secured by an arm 224 to the lower portion of the post 42 such that when the jack is pressed vertically against the abutment the relative movement of the two parts of the jack causes the pin 216 to engage the plunger 212 of the valve 202 and thus admit fluid to the cylinder 190 via the conduit 200 and the valve 230. The fluid acts on the piston 192 and through 194, 196 on the collar 198 secured to the control arm 180 and causes this arm to move backwards, i.e. away from the operator, and to trip the clutch which starts the automatic cycle referred to. Specifications 235,286, 510,177 and U.S.A. Specification 1,770,976 are referred to.

A synthetic resin cam disc 5, having a frusto conical scale 8, is rotatably adjustable on a shaft hub 10 against a ratchet formed by a sprung ball 2 on the hub disc 1 engaging internal teeth 6 on the cam. The leaf spring 3 mounting the ball 2 maybe extended rearwardly to form a one-way ratchet with the teeth 6. A second cam disc 18 is axially biased by a Belleville washer 21 against cam 5, which has sets of balls 15 or 16 ratcheting over annular fine or coarse pitch face-teeth 20 or 19 in the cam 18 or vice versa. A leaf spring (25) in cam 5, Fig. 6 (not shown), may engage teeth 20 or 19 to provide a one-way ratchet adjustment of cam 18 which preferably acts opposite to that of leaf spring 3. In a modification, Fig. 7 (not shown), two identical resilient cam discs (26, 27) have annular face teeth (28, 29) engaged by sets of balls (32, 33) or a single set carried by a resilient disc (31) fast on the shaft hub (30). The positions of the balls (32, 33) and teeth (28, 29) may be reversed. Several relatively adjustable cam discs may be arranged through a ratchet on a shaft of an electric switching block.

In an electrometer amplifier in which there is negative feedback around the first stage V 1 , produced by resistor Rg interconnecting the input and output terminals of this stage, the rise time is kept short in spite of the inherent input capacity C o  and capacity C s  shunting resistor Rg by arranging between the amplifier output and the input of the second stage V II  a series resistor R 1  shunted by capacitance C 1 . The input impedance Re of the second stage is assumed to be low. The feedback resistor Rg may be shunted by additional capacity Cg so as to swamp out the effect of variations in the input capacity C o . An expression is given in the Specification for the necessary relationship between the resistances and capacitances in the circuit for the rise-time to be a minimum. As shown, the first stage amplifier V I  comprises a screen-grid valve direct coupled to a cathode follower.

Abstract: 782,516. Woodworking. DRUMMOND, E. P. Feb. 9, 1956 [Nov. 22, 1954], No. 33724/54. Class 145. A machine for trimming and smoothing the sides of pre-shaped staves 80 for barrels or tubs comprises a work holder 81, 82 on a slidable table 85 and a pair of circular saws 33 and a pair of smoothing cutters 57 inclined towards each other at the bevel angle of the sides of the finished stave. The work piece is clamped between the upper and lower parts 81, 82 of the work holder by means of a lever 96, screw shaft 92 and adjustable toggle linkage 90 and the clamping faces of the parts 81, 82 are shaped longitudinally and transversely to accommodate the pre-shaped stave, being curved longitudinally, as shown, when a barrel stave is being operated or, for a tub stave, being sloped downwardly from front to rear. By reason of the inclination of the saws and the angle of the slope of the stave in the work holder, the width of the strips cut from the sides of the pre-formed stave will vary in accordance with the varying level at which the cuts are made by the saws and cutters and longitudinal tapering of the stave will be effected at the same time as the sides are bevelled. A table 20 carrying the work holder table 85 is adjustable vertically by a hand wheel 27 and screwed shafts 17, 18 to provide for variation in the longitudinal taper of the staves and the work holder table 85 is slidable by hand on rollers 86 and steadied by rollers 87. The saws are carried by a slidable plate 35 and pivoted plate 45 adjustable by handwheels 43, 53 so that the lateral spacing and inclination of the saws can be adjusted ; the smoothing cutters are similarly mounted.
