Title: Improvements in or relating to machines adapted for performing a burnishing operation in the manufacture of shoes
IPC: A43D95/16
Filed: 1940-12-14
Abstract: 545,843. Shoe-burnishing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Dec. 14, 1940. No. 17698. [Class 17 (i)] Addition to 519,673- [Also in Group XXIII] The machine described in the parent Specification is lubricated by a force pump carried by the heavy sprung casing providing the tool-shaft bearing. One of the pairs of tools can be disconnected from the drive while the other pair remains in operation. The tool and its carrier are held in interlocking engagement so that there is no play to cause wear. Line shafting or an electric motor drives a pulley 64 keyed to a shaft 45 rotating in bearings 25 in the heavy sprung casing and having an eccentric portion 47 rocking the tool shaft 41. The shaft 45 is reduced in three stages from the left hand bearing so that it can be removed when a cover-plate 63 has been detached. The shaft drives an oil pump 80 drawing from a sump 16 the bottom of which is formed with cooling fins past which air is drawn by a fan. The oil is forced to the bearings on shafts 41, 45. The tool shaft 41 is divided and its ends halved and clamped together and to an arm oscillated by the eccentric 46, the clamping bolt being accessible through an opening in the cover plate 56. The outer end of each part of the tool shaft carries a head 13 formed on its face with diametrically opposite recesses to receive projecting lugs 154 of the tool carrier, which carrier is urged inwardly by a spring 148. Between the recesses the head presents sloping cam surfaces 168 to the lugs. A handle 156 is pinned to a shaft carrying arms 158 terminating in plates below the lugs. On swinging the handle the head is removed from its locking recesses, the lugs are shifted on to the cam-surfaces, and the oscillation of the tool head causes the lugs to slide round the sloping cam-surfaces and change the relative position of the tools. If it is desired to disconnect one of the tool-heads from the drive, e.g., for changing a tool,'a handle 208 is swung to project a pair of stops 184 into the path of the lugs. The stops are held in operative position by a pawl 216. The burnishing tool is held on its spindle 224 without play by a bolt 230 clamping together complementary surfaces 232 on the tool and tool carrier. The tool is slotted to engage the bolt and a spanner 252 for loosening the nut to permit the tool to be changed, is provided with an arm 254 for swinging a slotted distance piece from under the nut when this has been loosened. In a modification, the tool has a dove-tail, and a complementary holder has one side bolted in place.

Title: Improvements in or relating to Producer Gas Plants.
Inventor: BAMBER HERBERT WILLIAM
IPC: C10J3/80
Filed: 1917-11-30
Abstract: 121,161. Bamber, H. W. Nov. 30, 1917. Producers.-The water-supply for a gas-producer is automatically controlled by interconnecting its valve with the gas-egress valve, or with the throttle valve of the engine. As shown in Fig. 1, the throttle valve e of an interna.l-combustion engine on a car is connected to a lever g which is connected by a spring ! i to a hook j on a lever-arm l which overhangs a spindle o<1> of a valve o. In the closed position of the valve e, a fixed arm on the lever l prevents the lever from contacting with the spindle o<1>, and so the valve o is allowed to open under the pressure of water admitted by a pipe s from a pump to a passage r, and the water escapes by a passage p without passing to the producer. When the valve e is opened, the lever g puts the spring i under tension, and the lever 1 acts on the. valve stem o' and tends to close valve o, thereby allowing a ball or spring-pressed valve t to be opened by the pressure of water in the passage r. The water is supplied to the producer by way of a passage u, the amount of passage depending on the degree to which the valve e is opened. In a modification, the throttle valve 6, Fig. 4, and the watersupply valve 7 which controls the flow from a cistern 1 to a float chamber 3, are interconnected by link mechanism as shown. The chamber 3 supplies a small boiler 10, and when the throttle is closed, the water in the boiler and the chamber 3 are evaporated before the generation of gas ceases. On re-starting, the producer is not cooled by the immediate introduction of water, owing to the time taken in re-filling the tank 3 and boiler 10.

Title: Improvements in or relating to electronic trigger circuits
Inventor: BAKER GEORGE THOMAS
IPC: H03K3/12
Filed: 1947-07-05
Abstract: 665,821. Valve relay circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Jan. 14, 1948 [July 5, 1947]; No. 17799/47. Class 40 (vi). In a trigger-pair circuit comprising two reciprocally coupled valves a non-linear resistor is included in the coupling circuits so that the circuit is less likely to be triggered by spurious positive pulses when it is operated at a low supply voltage. The Figure shows valves VA, VB reciprocally coupled and having two stable states of equilibrium so that negative triggering pulses applied at P cause the circuit to change over. The non-linear resistors NLR1, NLR2 which may consist of discs known under the Registered Trade Mark " Atmite are such that when the applied voltage changes the resistance changes inversely by a considerable amount. Initially valve VB is conducting so that relay B is operated and valve VA is cut-off with relay A released. When a negative pulse is applied at P the grid potential of valve VB falls and the valve is cut-off the potential at Y rises so that valve VA is rendered conducting and the potential at point W falls the effective value of resistors NLR1, NLR2 changing so that a greater potential difference exists between the control grids and the trigger action is thus more well-defined than if linear resistors had been used. As the relays A and B are in the anode circuits of the valves they have substantially no effect on the triggering action. The trigger pulse input circuit is isolated from the non- linear resistors by high value resistors YC and YG. Specification 665,906 is referred to.

Q1 has a negligible value when no voltage exists across it, but acquires a significant value when a voltage such as V H  is applied via Q2 across it, the resulting stored voltage causing Q1 to conduct when an input pulse CS is applied to the drain D. The pulse CS is thus able to charge a load CL, provided that CF which is periodically charged by Q2 to V H , is not discharged by a logic circuit Q3 to Q5 in response to signal A or B or both. A plurality of circuits 10b 10c all similar to 10a is supplied by the same pulse CS and the negligible value of CF in those cases where the A, B signals have discharged it, reduces the total capacitance which pulse CS has to drive.

Title: Improvements in piezo-electric frequency control devices
IPC: H03H9/19
Filed: 1925-07-16
Abstract: 239,175. Western Electric Co., Ltd., (Assignees of Marrison, W. A.). Aug. 26, 1924, [Convention date]. Piezo-electric crystal units.-A piezo-electric crystal for use as a frequency control element is designed so as to vibrate at lower frequencies than usual, for example, frequencies within the voice range, whilst still remaining of small dimensions. According to one method, the natural frequency of the crystal for longitudinal vibrations is brought within the audible range by increasing the ratio of mass to restoring force by forming the crystal of dumb-bell shape 11, Fig. 3. The crystal is preferably cut with its longer axis 1 perpendicular to one of the natural faces of the original crystal. According to a second method, low-frequency vibrations are produced by causing the crystal to vibrate transversely. This is effected in a parallelepipedshaped crystal by placing the metallic plates 13 supplying the exciting voltage along one edge of the crystal as shown in Fig. 5. In the arrangement shown in Fig. 8, both halves of the crystal mav be used bv connections as ;hown, or an E.M.F. of natural frequency approximating to that of the crystal mav be applied to plates 13 and a resultant E.M.F. of frecueney determined solely by the crystal may be taken off at plates 13<1>. Specifications 245.810 and 258,707, [Class 40 (iv), Telephones &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also arrangements for obtaining transverse vibrations by arranging one electrode 17 centrally. This may be effected by drilling a central hole 16, Fig. 9, or by saw-cuts, Fig. 12. In another arrangement, the central electrode may comprise one or more light spiral springs, Fig. 11, which give a larger electrode area.

Patent GB-182049-A (GB)
Abstract: 182,049. Pollak, J. E., (Siemens & Halske Akt.-Ges.). Oct. 18, 1921. Automatic exchange systems.-A connector serving groups of lines belonging to private branch exchanges, and having it may be two or three groups in each level, is raised by the concluding digit to the level containing the wanted group and then rotates automatically, the test circuit being rendered effective onlv for contacts of the wanted group owing to the effect of a previous digit which determined a choice of routes over which access was had to the connector. The connector W can be seized by a selector Wv over either of several levels Z<1>, Z<2>, Z<3>, energizing the relay R<1> either alone or in conjunction with-relay R<2> or R<3> and thereby energizing over the lead c the relay C either alone or in conjunction with a polarized relay R<P1> or R<P2>. By this means battery is connected to one of the contacts 116, 117, 118 corresponding to the level over which the connector was seized. The connectibn of the test relay P to the contacts 116, 117, 118 is controlled by a switch U, which is mounted on the connector shaft and is operated by a cam S-shaped to correspond with the distribution of the P.B.X. groups in the various levels. For example it may be supposed that the connector has been raised to its ninth level. At the termination of bhe digit the relapse of the relay V<2> completes an interrupter circuit for the rotary magnet D. It will be seen that during the first two rotary sieps the test relay P<1> is connected to the contact 116, at the third step the cam S transfers it to the contact 117, and at the seventh step to the contact 118. Consequently, accordingly as the connector has been seized over the level Z<1>, Z<2>, or Z<3> the test relay will be energized on the first idle line of the first, second or third group. The energization of the test relay opens the circuit of the rotary magnet.

Title: Combustion turbine combination specially for driving vehicles such as motor cars and the like
IPC: F01K15/02
Filed: 1922-07-03
Abstract: 203,828. Fries, G., and Schneider, H. July 3, 1922. No Patent granted (Scaling fee not paid). Working-fluid supply; driving and transmitting mechanism, special applications of. - Relates to an internal-combustion turbine combination comprising two turbines connected to one another by a differential gear through the driven member of which power is transmitted. Fig. 2 shows one-half of the combination. The carrier b of the planet wheel c is furnished with a helically - toothed wheel d which drives an air compressor of the axially-sliding abutment type through a similar wheel e and spur wheels. The compressed air passes by a pipe m into a distributor comprising a cylinder o having spaced slots p and rotating in a cylinder q. The compressed air passes by pipes r to two valves s, each portion being then mixed with gaseous fuel and passed to an explosion chamber t having one end formed with a crown of guide vanes leading to the turbine wheel u. Between the guide vanes and the turbine wheel is inserted a disc valve w, with openings corresponding with the guide-vane openings, controlled by a piston 1 subjected to the pressure of the explosive chamber and the pressure of a spring. On igition of the gases the piston is driven up, causing the disc w to turn and allow the gases to flow across the turbine wheel. As the pressure falls the spring returns the piston to its lowest position. To use one turbine only of the combination, the bevel wheel 5 is stopped by means of a brake 7, 8. The number of revolutions of the carrier c is thereby reduced by one-half and the speed of the compressor correspondingly reduced. The explosion chamber is cooled by a cone 10 filled with water and by steam or water injected into the chamber by way of a valve 11.
