Title: Improvements in automatic weighing machines
IPC: G01G21/00
Filed: 1924-03-14
Abstract: 213,557. Librawerk. March 29, 1923, [Convention date]. Automatic-feed weighers. - The material in suspension at cut-off is compensated for by means of a lever which is removably arranged to pivot on the fulcrum block of the weigh beam. In a modification the lever is supported loosely by two projections on the weigh beam. In the arrangement shown in Fig. 1, the bearing blocks i supporting the weigh beam k are extended to receive the knife-edges g of the compensating lever b. One arm of the compensating lever bears an adjustable weight h, and the other arm has a portion f passing under the weight-pan side of the weigh beam and exerting a sufficient pressure thereon to compensate for the suspended material. By raising the weighted end of the compensating lever its influence may be removed from the weigh beam. In a modification, Fig. 3, wherein knife-edge supports for the compensating lever are dispensed with, the weigh beam is provided with two projections a, a' which engage notches in the upper and lower edges of the compensating lever b. A pin d on the frame projects into a large aperture in the compensating lever and forms a support for the compensating lever when its weighted end is raised.

Title: Vertical Sorting Conveyer System.
Inventor: WENTZ EDWARD A
IPC: B65G17/34
Filed: 1968-02-09
Abstract: 1,171,051. Endless conveyers. AEROJET-GENERAL CORP. 9 Feb., 1968, No. 6566/68. Heading B8A. A vertical sorting conveyer system comprises a carrier 28 movable on a frame 7 and having a tray 35 movable between an initial position (Fig. 8A) and an extended position (Fig. 8B) for transfer of cargo 45, actuating mechanism for effecting the movement of the tray 35 comprising an abutment 200 movable relative to the carrier frame, an operator controlled abutment 205 disposed to be moved into the path of the abutment 200, and means connecting the abutment 200 with the tray and operative to effect movement of the tray (when the abutment 205 is moved by the operator) to move it into its extended position. There are a plurality of carriers 28 and they are each pivotally connected at 116 (Fig. 5) to an endless traction chain 15. When the cargo 45 waiting on tines at a loading station 43, is intended to be picked up by a rising carrier 28, the abutment 205 at the station 43 is moved by operator control to dot-dash position (Fig. 4). The abutment 200 on an endless chain 90 mounted in the frame of the carrier 28 is then engaged by the abutment 205 as upward travel of the carrier proceeds. Chain 90 is thereby caused to move, and transmits movement to a horizontally disposed chain 127 carrying a pusher 180. The latter is in sliding engagement with a bore in a member 192 rigid with the tray 35. Thus the latter is projected into an article receiving position (Fig. 8B and dot-dash position Fig. 7). After loading has taken place at station 43, the tray is automatically retracted (Fig. 8C) by the action of a stop 225 engaging a fixed stop 230. A similar arrangement results in projection of the tray on the downward travel of the carrier 28 if an operator controlled stop 238 is projected, so as to engage a stop 235 carried by an endless chain 95. Discharge thus takes place on to forks at a station 50. On the vertical upward and downward runs of the elevator the carrier 28 is guided by parallel guide rails 60 (Fig. 4). As the carrier passes across from its upward to its downward run or vice-versa it passes out of the guides 60 and engages vertical rollerways (55), (55), (Fig. 1, not shown).

Abstract: 889,891. Electric selective signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO. and STANDARD TELEPHONES & CABLES Ltd. Feb. 23, 1960 [Feb. 26, 1959], No. 6738/59. Class 40 (1). [Also in Group XIX] In a device for converting a 17-bit pure binary number registered on 17 triggers M1 to M17 into a binary-coded decimal form the outputs from the triggers are so connected to six further triggers MU (units), MT (tens), MH ... MHTh, Fig. 1, together with clock pulses TA1, TA2 &c., that the further triggers are turned on for periods which correspond to the number of pulses that should be entered into the various denominations of a binary-coded-decimal accumulator. For example if a one is registered in trigger M8, corresponding to 128, trigger MH is turned on by TA1 for a duration of one clock pulse, trigger MT is turned on by TA12 for two clock pulses, and trigger MU is turned on by TA28 for eight clock pulses. Triggers MU, MT, MH, &c., gate clock pulses to an accumulator of which the hundreds denomination is shown in Fig. 3. Pulses to be counted arrive on a lead MH and pass to four.cascade-connected triggers MAH, MBH, MCH and MDH, and to a trigger MHC which is arranged to go on when the tenth input pulse is received; the other triggers are arranged to reset themselves when the tenth input pulse is received. It is stated that a similar arrangement could be used for conversions from pence in pure binary to sterling in binary-coded-decimal or to the " Murray " code. In a modification pulses are subtracted, and not added, to an accumulator.

Title: Wheel-dressing mechanism
IPC: B24B53/07
Filed: 1946-03-05
Abstract: 615,745. Dressing grinding-wheels. HERBERT, Ltd., A. March 5, 1946, No. 6751. Convention date, March 16, 1945. [Class 60] [Also in Group XXXVII] Dressing mechanism for an abrasive grinding- wheel having a peripheral contour includes a contoured wheel dressing roller adjustable in various ways and having means, during rotation of both the grinding-wheel and the roller to press the roller into the peripheral face of the wheel. A slide 26 is movable on a base 14 to bring a hard steel crushing roller 160 towards or away from a grinding-wheel 12. A cradle 48 is adjustable in a saddle 32 on the slide 26 to incline the axis of the roller to the same angle relatively to the grinding-wheel axis that the work is held during the grinding operation. A plate 62 is mounted, for slight pivotal adjustment about a pivot 64, on the cradle 48 and is formed at its forward end with an upwardly projecting part 86. A slide 92 carrying the crushing roller is adjustable on the part 86 so as to vary tangentially the point of contact of the roller with the grinding-wheel, this being necessary when the wheel is to grind work of a different size and thus, in the case of centreless grinders when the work contacts the wheel at a different part of the wheel circumference. The slide 26 has formed thereon two longitudinally spaced apertured lugs 170, 172, a bushing 174 being fixed in the lug 170 and an internally threaded bushing 176 keyed for longitudinal movement in the lug 172, a powerful spring 180 between the two bushings pressing a shoulder 179 on the nut 176 against the lug 172. A shaft 182 extends through the bushing 174 and is threaded to engage the lug 172. The shaft 182 is rotated relative to a sleeve 184 by a member 192 to bring the roller 160 up to the wheel, the whole mechanism is then moved a limited distance from the wheel by a handle, 212 and pinion 204 engaging rack teeth on the sleeve 184. The shaft 182 is then rotated again to move the roller forward the desired amount that it is to be fed into the wheel, and the whole mechanism then moved back, by the lever 212 moving the same distance as before, into contact with the wheel 12, the spring 180 this time being compressed when contact occurs and thereafter acting to press the roller forward the desired amount. Switches 218, 219, Fig. 2, are closed by the movement of the handle 212 so that the roller motor is energized when contact between the roller and grinding-wheel takes place, the motor being automatically stopped when the load on the roller decreases. The circuit is so arranged, Fig. 8 (not shown) (see Group XXXVII), that upon the operation of a stop switch the grinding- wheel motor is brought to a stop by reversing the current thereto, and, upon operation of the roller motor, the grinding-wheel is rotated in a reverse direction for the crushing operation. The peripheral speeds of the wheel and roller may be the same. Rollers having distorted thread profiles instead of alternating V-shaped ridges and grooves may be used. A brush 236 on the slide 92 is used for cleaning the roller.

Abstract: 579,405. Broaching. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.). April 13,.1944, No. 6828. [Class 83 (iii)] A broaching-machine is particularly designed for making U-shaped collars C, Fig. 3, from strip stock S by means of slotting broaches B, B' and a final slitting broach B<2>, all mounted on the same tool ram. Two superimposed strips S, Fig. 6, may be acted upon simultaneously and are supported on a work-holder 44 attached to a main slide 30 movable to and from the broach head 20 on a base 22. A work clamp 41a is carried by levers 41 pivoted at 43 on the slide 30 and is actuated by levers 42 pivoted at 42a on the slide 30, a hydraulic cylinder 40 on the slide, Figs. 1 and 6, having its piston 81 connected to a rock shaft 83 journalled in the levers 42 and provided with eccentrics 85 engaging abutments 86 on the slide so that advance of the piston will rock the levers 42, 41 and clamp the work. The broaches B, B<2> are carried by the head 20 sliding in fixed guides.21 and the broach B' has a T-slot connection 24 with the head 20 and slides in guides 37 mounted on a slide 34 movable in horizontal guides on the slide 30. An eccentric 60 on a shaft 56 journalled at 57, 58 on the base 22 engages a slot 61 in the slide 34 and is oscillated to move the slide by means of a rack and pinion 53, and a hydraulic cylinder 50 on the base. A lug 65 on the slide 34 has a bush 66 adjustably screwed therein which slides on a fixed guide rod 72 and is adapted'to engage a lug 70 on the slide 30 to move the latter at the required times. In operation, when the broach head 20 has completed its downward cutting stroke, oil is admitted to cylinder 50 to rotate the eccentric 60 and move the slide 34 to the left in Figs. 1 and 6, thus withdrawing the broach B<1> along the bracket 24 clear of the work. When the bush 66 meets a cross bar 75 on the slide 30, this slide moves with the slide 34 to withdraw the work from the broaches B, B<2> and the broach head is then raised on its return stroke, after which oil is admitted to the cylinder 40 to unclamp the work. Oil is next admitted to a cylinder 90, Fig. 1, slidable on guide rods 91 attached to the slide 30 and having a piston 96 attached to the slide. The cylinder carries pivoted grippers in contact with the work so that movement of the cylinder will feed the work by an amount determined by stops 112, 113 on the guide rod 91 whereupon cylinder 40 is reversed to clamp the work and cylinders 50, 90 are reversed to return the work and broach B<1> to operative position and return the cylinder 90 ready for another feed. The eccentrics 60, 85 lock the slide 34 and work clamps in operative position and a spring 74 on the guide rod 72 engages bar 75 on the slide 30 to assist the operative movement of the slide and cushion the idle movement. The hydraulic valves may be operated automatically or manually.

Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M19/02
Filed: 1926-03-15
Abstract: 254,264. Schimanek, E. June 27, 1925, [Convention date]. Spray carburettors.-The air and fuel are controlled simultaneously by an axially moving suction-actuated piston and the ratio of air to fuel may be varied independently by rotating the piston by hand or by atmospheric pressure. Air enters at 2, Fig. 1, and passes to a chamber 7 through a port 5, in a cylinder 6, controlled by a suction-actuated piston 4 having a recessed part 13 with sloping edge 16. Fuel from a float chamber 8 passes through a tubular extension 9 of piston 4 and a duct 10 therein to chamber 7 and the resulting mixture is drawn away at 3. The fuel flow is controlled by the extension 9 moving over a needle valve 11. Suction is transmitted to the space above the piston by ducts 18. The mixture strength is varied by rotating the piston 4 by an arm 14, disc 21 and pin 19, thus varying the air opening for a given fuel supply. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following modifications : The fuel control needle is vertically adjustable and in a further modification the piston 4 is prevented from rotation and has a manually adjustable screw connection with the tubular part 9 whereby the latter may be raised or lowered relatively to the piston. In the form shown in Fig. 4 (Cancelled), particularly applicable to aeronautical engines, the needle valve 11 is attached to a flexible diaphragm 20 so as to enclose a space 21 filled with gas at atmospheric pressure. In a modification of this form, the flexible diaphragm is replaced by a spring-loaded piston the underside of which is subjected to the suction of a pump driven by the engine. In a still further modification, the engine-driven pump is replaced by an ejector apparatus comprising one or more Venturi tubes. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric oscillation generators
IPC: H03K4/92
Filed: 1937-03-12
Abstract: 491,934. Valve generating circuits. FAUDELL, C. L., and WHITE, E. L. C. March 12, 1937, No. 7263. [Class 40 (v)] A relaxation oscillator for generating sawtooth oscillations comprises a condenser adapted to be slowly charged (or discharged) through an inductance coil forming therewith a lightly-damped oscillatory circuit, the period of which is long compared with the time interval between synchronizing pulses applied to a valve through which the condenser is rapidly discharged (or charged). The arrangement is such that a change in frequency of the pulses will not affect the amplitude of the saw-tooth voltage wave. As shown in Fig. 1, the condenser 10 is charged through the coil 8 and is discharged through the valve 7 when this is rendered conductive by a positive pulse applied to the grid. The pulses may be line-frequency pulses in a television receiver, which may be supplied through an intermediate self-oscillatory pulse generator, the natural period of which is longer than the period of the received pulses. A limiting resistance may be connected between the coil 8 and the valve anode, Fig. 4 (not shown), the pulses being then of constant width. The valve 7 may be replaced by a blocking oscillator valve, Fig. 5 (not shown). As shown in Fig. 6, the valve 30 is of this type, and the circuit generates voltage waves of opposite phase across two condensers 40, 36 of which condenser 40 is charged through the coil 39 when the valve is nonconducting, during which period the condenser 36 discharges through the coil 38, a charge accumulated whilst the valve was conductive. Specifications 400,976 and 471,737 are referred to.
