Patent GB-640227-A (GB)
Title: Improvements in or relating to synchromesh couplings
Inventor: TARLTON FRANK HENRY
IPC: F16D23/06
Filed: 1947-07-31
Abstract: 640,227. Change-speed gearing; positive clutches. ROLLS-ROYCE, Ltd. July 31, 1947, No. 24680/46 [Class 80(ii)] In a positive clutch, having frictionallyoperated balking means which detect but do not assist synchronization, and comprising a toothed clutch member 32, having rotatably secured thereto a friction disc 33 and co-acting with an axially slidable toothed clutch member 29 having balking means in the form of a friction disc 34 maintained in light frictional contact with the disc 33 by a spring washer 40 in a casing 41 secured to the latter disc, the member 29 entrains the disc 34 through T- shaped axial lugs 36 on, but extending radially inwardly from, the disc and engaging slots 35 in the member. With the clutch disengaged, only the tails of the lugs enter the slots, lack of synchronization causing the tails to move to one or other side of the slots and block engagement of the toothed members. Reversal of torque on the disc 34 on passing through synchronization causes the lugs to float to the centre of the slots which are just wide enough to allow the heads of the lugs to enter so that the toothed members can be engaged. As shown, the clutch is applied in a change-speed gear of the kind described in Specification 640,228 to couple the input gear 11 directly to a hollow shaft 25 and so overrun a gear 17, connected to the gear 11 by an underdrive countershaft train and normally powering the shaft 25 through a free-wheel coupling (not shown).

Abstract: 1,173,819. Imitation solid fuel fires; burners. J. IRVINE. 27 May, 1968 [26 May, 1967], No. 24702/67. Heading F4T and F4W. In a gas operated imitation solid fuel fire, gas is supplied by a pipe 22 below a baffle 20 to percolate through non-combustible material 50 to burn at the surface 54, and decorative members simulating solid fuel rest on the material 50. The non-combustible material 50 comprises a foamed granular mix of silica and calcium aluminium silicate, the particles having approximately # inch diameter and is topped by a layer 52 of soft furnace clinker or foamed slag in a size range 1/16-“ inch. Carborundum filings may be applied to the surface of the decorative members which may be of a cement mix, and be internally reinforced. The imitation logs may be replaced by pieces of slag to simulate coal. An air register, Fig. 3 surrounds the gas supply nozzle 34 at the end of pipe 22.

Title: Portable dental handpiece
IPC: A61C1/06
Filed: 1974-06-04
Abstract: 1460046 Dental handpieces J W COPELAND 4 June 1974 [2 July 1973] 24741/74 Heading A5R A portable dental handpiece 10, Fig. 1, comprises an, output shaft 40 connected by a speed-changing belt and pulley arrangement 48, 46, 38 to a drive shaft 36 of an electric motor 28 powered by a battery 30, the motor and the battery being contained in a hollow handle 20 having a mount 22 on one end thereof for removably mounting a dental tool 24 in operating position thereon, a coupler 76 being connectable between the output shaft 40 and a shaft 68 of the tool, and a sleeve 58 of the mount being engageable with the tool for rotatably mounting the tool on the sleeve. An induction coil 79 for recharging the battery is mounted in the handle. A control switch (75) Fig. 2, (not shown), is mounted on the handle and is operable to connect the motor and battery. The diameter of the pulley 38 on the motor shaft is less than that of pulley 46 on the output shaft so that the speed of rotation of the tool is less than that of the motor shaft; this provides a rotation speed suitable for a prophylaxis head tool. Different pulley sizes may be used to provide an increased speed of rotation of the tool over that of the motor shaft, thus being suitable for cutting and polishing tools. A second control switch (134) Fig. 5, (not shown), may be provided on an outer member (128) of the mount, a pair of contacts (152), (154) Fig. 6, (not shown), on the outer member engaging a pair of contacts (146), (148) on the handle when the outer member is mounted thereon. Alternatively, a three pulley and belt arrangement is used to effect said speed change. The battery may consist of two cells 310, 312 Fig. 18, a switch 316 being connected to cell 310 and to the motor 314 and a switch 324 being connected to cell 310, to cell 312, and to the motor in a series relation, operation of switch 316 effecting a lowspeed tool rotation of the tool and switch 324 effecting a high-speed tool rotation. Instead of an induction coil recharging apparatus, the handle may have contacts 334, 336 on its base so that the battery may be recharged on placing the handpiece in a recharging stand (268), Fig. 16, (not shown).

Filed: 1925-10-08
Abstract: 242,252. Aktiebolaget Birka Regulator. Nov. 3, 1924, [Convention date]. Thermostats. - The current to the electrical heater 2 is regulated by a main thermal switch 6 and an auxiliary thermal switch 7, the latter being arranged near the heater so as to open its contacts 14 when the heater reaches a certain temperature and thereby removes a short-circuit from the heating coil 10 of the main switch, which then opens and closes its contacts 8 in a well-known manner so as to reduce the supply of current to the heater 2 to a suitable amount. The switches 6, 7 are preferably both of the bimetallic kind as shown. The auxiliary switch 7 comprises two springs 12, 13 carrying contracts 14, the strip 13 being engaged by the head of a screw 16 which is adjustably secured in the bimetallic member 15. The main switch 6 is enclosed in a receptacle 11 which is evacuated or filled with an inert gas. In a modification both switches are enclosed in such receptacles or they may be enclosed together in one receptacle which is placed in thermal relation to the heater 2. In this latter case, should the auxiliary switch 7 fail to act, the main switch 6 will still open its contacts, though at a somewhat higher temperature.

Epicyclic gearing having ratio establishing brakes and clutches is arranged such that in changing gear a clutch or brake which was engaged in the previous ratio remains engaged. As shown first, second and third trains 80, 90, 100 provide four forward speeds and reverse, an input shaft 71 being connected to the ring 83 and sun 91 of the first two trains, the planet carriers 82, 92 of these trains being interconnected and fast with the ring 103 of the third train which has an output carrier 102. The sun 81 of the first train can be stationed selectively by a brake B 80  or clutched by a clutch K 70  to the carrier 82 which can be braked by a reverse brake B R . The sun 101 can be stationed by a brake B 100  and is connected by a one-way clutch F 3 , which can be bridged by a clutch K 100 , to the ring 93. First gear is obtained with brake B 100  applied and one-way clutch F 3  operative, lock-up clutch K 100  being engaged if engine braking is desired. For second gear brakes B 100  and B 80  are applied, clutch F 3  overrunning. For third gear brake B 100  and clutch K 70  are engaged, and for fourth gear clutches K 70 , K 100  are applied. Reverse is obtained with brake B R  applied and clutch F 3  operative, the lock-up clutch K 100  being engaged if engine braking is required. In a modification (Fig. 2, not shown) the first two trains are arranged differently. The first train has an input sun, the carrier of the first train and ring of the second are stationable by a reverse brake and connected to the ring of the third train, and the ring of the first train and carrier of the second are connected by the one-way clutch to the sun of the third train. The second train has a sun selectively stationable by a brake and clutchable to its carrier. In another modification (Fig. 1, not shown) two trains are provided giving three forward speeds and reverse. In this case the train 90, brake B 80  and clutch K 70  are dispensed with, the sun of the first train being connected to the sun of the output train by the one-way clutch, and a clutch being provided between the ring and carrier of the first train.
