Title: Improvements in or relating to torsionmeters
Filed: 1930-09-05
Abstract: 356,474. Torsion meters. THRING, L. G. P., 8, Park Terrace, Cambridge. Sept. 5, 1930, No. 26510. [Class 106 (ii).] Relates to the type in which relative angular movement between two parts clamped to a shaft at points a suitable distance apart is indicated by light reflected from a mirror pivoted to one part and turned when the other part moves relatively thereto, and consists in providing two mirrors so mounted on a common support rigid with one part as to lie at right-angles to a single plane which is adjusted to coincide with that plane in which the mirrors rotate with the body part. One flange A of the flanges A, B of the relatively moving parts has bolted thereto a mirror supporting frame C which carries two spaced parallel mirror supporting plates C<1>. Each plate C<1> is formed with a shallow cylindrical recess in which is disposed a cell D carrying a mirror D<1>. Between the plates C<1> is a transverse member C<2> carrying a tapered 356,474.-cont. bearing C<3> for one end of a pivot pin E the other end of which engages a tapered bearing E<1> mounted at the end of a leaf spring E<2> secured to the plate C. Secured to the pin E is a support F for parallel cells and mirrors F<1>, F<2>. Rigid with the support F are two arms F<5> through which extends a rod G one end of which is secured to one arm while an intermediate part is provided with a collar G<1> fitting closely a bore in the other arm. The free end of the rod G passes through and is fixed to the outer end of an L-shaped resilient member H the inner end of which is secured by screws to a cylindrical block H<1> in the bore J of a member J<1> bolted to the flange B. In order to adjust the initial position of the support F, the block H<1> is moved in the bore by a screw H<3> engaging a screwed sleeve extension of the block against the influence of a spring H4 which takes up any slack in the screw. A block k sliding at right-angles to the bore J is moved by a cone-headed screw K<2> to lock the adjustment. The mirrors D<1>, and also the mirrors F<2> in zero position, must be at right-angles to the plane in which they revolve. Slight inaccuracies of adjustment may be compensated by unclamping the plates D<2> by removing screws D<3> and rotating the cell D. To correct for inaccuracies in the face of the flange A on which the plate C rests, a tapered base C<4> is formed adjacent and parallel to one edge of the baseplate, a slot extending from this base to the edge. By moving a tapered pin L the edge portion can be sprung to adjust the plane in which the plate C lies relatively to the flange A. In a modified form the mirror support F is operated by a resilient rod and the movement of the mirror support F is controlled by a dashpot comprising a plate or plates moving with the support and arranged between fixed plates contained in a casing filled with a viscous fluid. Specification 307,974, [Class 106 (ii), Dynamometers &c.], is referred to.

Title: Tyre Testing Machine.
IPC: G01M17/02
Filed: 1967-06-09
Abstract: 1,155,341. Testing tyres electrically. UNIROYAL ENGLEBERT FRANCE-SOC. ANON. June 9, 1967 [June 24, 1966], No.26639/67. Heading G1N. Apparatus for determining the lateral parasitic faces produced in a tyre comprises a differential transformer for measuring the displacement forces during equal periods of running in the forward and reverse directions, the average displacement in each direction representing the lateral force produced by the interaction between the tyre and the ground in that direction, the alternating component in each direction representing the alternating component of the parasitic forces, and the difference between the average forward and reverse displacements representing the unidirectional component of the parasitic forces, equivalent to overall conicity of the tyre. The tyre 10 Fig. 3 is mounted on the wheel J and hub 8 of a testing machine, to be rotated by motor M through gearing R, and inflated from a pressure source (not shown) through the hollow shaft b until stopped by a pressure switch at the required pressure. A pneumatic system V now lowers the tyre and wheel assembly on to roller 11 mounted on a platform 13 supported by leaf-springs 14, and the motor M is energized to rotate the tyre for three revolutions in the one direction, then three revolutions in the opposite direction. The lateral forces developed by the tyre are transmitted through the roller 11 and platform 13 to the core N of a differential transformer CA, whose output voltage thus indicates the magnitude and direction of these forces. The signals are rectified and fed through changeover switches to two integrating circuits, one for each direction of rotation, and stored in two memory circuits, to be subsequently analyzed to determine the values of the various components of the lateral parasitic forces. The apparatus is coupled to an electrical control system which, via relays and a timer, automatically programs the tests on a tyre after it is located on the test wheel, and analyzes the electrical output signals to provide the various component values. Calibration is effected by attaching a cable to platform 13, passing it over a pulley 17 and attaching a known weight.

Title: Embossing machine
IPC: B41J3/39
Filed: 1970-06-03
Abstract: 1286163 Selective embossing DENNISON MFG CO Ltd 3 June 1970 [3 June 1969 9 Sept 1969] 26790/70 Heading B6F An embossing machine comprises a housing 20 which carries a dialable embossing wheel assembly (50, Fig. 1) and a guide 30 for the material that is to be embossed. In addition, a spring-loaded actuator 40 is pivotally mounted at 21 to the housing 20. Depressing the actuator 40 brings about the desired embossment; releasing the actuator causes the material (60) to be advanced. Letter spacing.-The lower portion of the guide 30 (Fig. 3A) includes a shaft-mounted ratchet assembly with a ratchet wheel 31 that is operated by the same spring S used to load the actuator 40. A drive tyre (37, Figs. 3B and 3C) is internally serrated so that it is keyed to the ratchet wheel, and extends through an opening in the guide 30 into contact with the lower surface of the material (60) to be embossed. The upper surface of the material is contacted by an idler nip roller (36). An integral extension of the guide 30 acts as a detent (34b, Fig. 3C) to prevent back-spacing. In an alternative (Fig. 4C), the detent is provided with shoulder (34<SP>1</SP>c) to positively latch the ratchet wheel 31 against reverse rotation. As the actuator 40 is depressed, the spring 5 is carried over the ratchet wheel to an operating position (5<SP>1</SP>, Fig. 3A). Releasing the actuator causes the spring S to rotate the ratchet wheel one increment, thereby advancing the material (60).

IPC: H04N1/415
Filed: 1966-06-15
Abstract: 1,188,126. Facsimile transmission systems. XEROX CORP. 13 June, 1967 [16 June, 1966], No. 26805/66. Headings H4F and H4P. To reduce redundancy in binary signals obtained by scanning a printed document successive equal length words in the input data are inspected for the presence or absence of bits of a given level, e.g. 1-bits, and in the absence of such a bit in a word a characterizing bit is transmitted instead of the word. In the embodiment described 64-bit words are inspected. If the word being inspected contains only 0-bits, as does the first word in Fig. 4, a 0-bit is transmitted. If the word contains a 1-bit a 1-bit is sent and the word inspected in successive groups of 16-bits. If a group is all zero a 0-bit is sent. If a 1-bit is present a 1-bit is sent and the group inspected in successive sub-groups of 4-bits. If a sub-group is all zero a 0-bit is sent. If a 1-bit is present a 1-bit is sent followed by the 4-bits of the sub-group concerned. When all the subgroups have been inspected the next group is inspected, and when all the groups have been inspected the next 64-bit word is inspected. At the receiver the reverse process takes place, sequences of 0-bits containing 4, 16 or 64, bits being generated when necessary. The output of the scanner may be passed via a delta encoder (not described) before being inspected as above.

Title: Improvements in or relating to steam generators
Inventor: SMITH EDWARD
IPC: F22B29/00
Filed: 1958-08-21
Abstract: 864,136. Forced-flow steam boilers. INTERNATIONAL COMBUSTION (HOLDINGS) Ltd. July 31, 1959 [Aug. 21. 1958], No. 26971/58. Class 123(2) In a forced circulation boiler which may be associated with a nuclear reactor and wherein an evaporator 2 is supplied with water from a steam and water drum 1 by pumps 4 having respective isolating valves 5, 6 and delivering through respective non- return valves 6a, a pipe 8, 9 having an automatically operating valve 7 is provided to by-pass the pumps in the event of their failure, thereby to establish a natural circulation through the evaporator to avoid a complete shutdown whilst the pump defects are being corrected. The by-pass valve 7 may be held closed by the pressure head across the pumps whilst they are operating whereby pump failure would permit the valve to open. Alternatively, the valve may be solenoid operated, the solenoid being interlinked with the circuit of an electric motor driving the pumps. In the latter case the valves 6a may also be solenoid operated and interlinked in the same circuit whereby they are normally held open whilst the valve 7 is held closed but, on pump failure, are closed and the valve 7 is opened. In a modification, Fig. 4, a downcomer 11 from the steam and water drum is connected-to the upper chamber 16 of a header 12, the upper chamber being separated from a lower chamber 21 by a partition B in which is mounted a nap valve 14. A pump 17 draws water from the upper chamber and delivers it into the lower chamber whence it passes to the boiler heating surfaces through pipes 24. Normally the flap valve 14 is held closed by the pressure differential between the chambers. If the pump 17 fails, however, the flap 14 falls and the water from the downcomer passes directly through the header 12 to the boiler.

Title: Liquefaction of finely divided material
IPC: C03B17/04
Filed: 1971-04-19
Abstract: 1351641 Fused silica GLASROCK PRODUCTS Inc 19 April 1971 [12 March 1970 2 July 1970] 26976/71 Heading C1M In the continuous production of fused silica, finely divided raw material is introduced into a furnace, an electric are is generated in the furnace to form a globular melt of fused silica which is formed into a column by continuous removal from an opening in the lower end of the furnace. As shown in Fig. 1, a furnace 20, supported on a framework 10, comprises a cylindrical body 21 and frusto-conical base 26 terminating in a nozzle 27 supporting a lip 29 of refractory material through which the fused silica 9 flows to form a column C. The column C is surrounded and cooled by a sleeve 70 with an inner diverging wall 71 leading to a removable cup shaped cap 90 with a discharge nozzle 96 which may be closed by a slidable plate 97 with handle 99. The cap 90 is supported by a framework 100, 101 on an elevator 105, with hole 106 through which raw material may flow, which may be raised or lowered on a support 107. Sand or silica A is fed by a shoot (114) until the whole furnace down to cap 90 is filled, when an arc is struck between electrodes 40 so as to form a globe 9 of melt. Periodically, the raw material is bled off by opening plate 97 until only fused silica is flowing through cap 96, which is then lowered on the supporting framework 100, 101 by moving the elevator 105 downwardly, carrying the column C with it since hole 106 is too small for the column to flow through it. Water jackets 34, 30, 74 and 91 cool respectively the body 21, nozzle 27 and lip 29, sleeve 70 and the cap 90. In an alternative embodiment, Fig. 6, cylindrical body 201 is fed from a hopper 202 with powdered silica 204 which is heated by bar electrodes 205 in holders 207 fed by devices 208 to maintain suitable spacing between them to generate an arc. The melt 209 is extruded through steel nozzle 210 and is fed downwardly by toothed rolls 213 to guide rolls 214 and cooled by water jets 215, 216. A variety of different toothed rolls 213 are shown. In both embodiments, gas exhaust nozzles, as nozzle 220 in Fig. 6, are provided and if the angle of slope 201a is steep, nozzles 211 may also be provided. The solidified column in each case may be either directed on to an inclined conveyer 230, Fig. 6, or may be periodically broken off by clamping and sticking the lowermost portion with a pneumatic hammer.

[Class 80 (ii).) Free-wheel clutches for motor vehicles are automatically rendered bidirectional at low speed, as for reverse running, by a set of oppositely-acting clutch elements which are thrown or held out of action by centrifugal means during normal running. One clutch member preferably carries a casing revoluble therewith. A driving-shaft 2, flanged for attachment to the gear-box tail-shaft, carries an inner member 4 provided with oppositelyinclined wedging pockets 14 for clutch rollers 5, which coact with a driven drum 6 secured to oil-retaining casing-members 10 and a universal-joint or other transmission member 12. The reverse inclines 14 are preferably longer than the forward inclines and terminate in a slightly deeper recess 18, in order that the rollers may there be definitely out of contact with the drum 6. Pegs 19 project under the action of spring-retracted masses 21 to obstruct or displace the reverse rollers above a predetermined speed. Fewer reverse rollers than forward rollers may be used. In a modification, the member 4 is polygonal, each roller coacting with a flat to effect forward and reverse drive, the control means comprising bars, of the same length as the rollers, centrifugally projected from inclined slots to prevent the rollers from passing to the reverse-drive ends of the flats.
