The base member 1 is mounted by means of a turntable 32 on a body 33 and can be locked in adjusted position relative thereto by a screw 34, and the body can be secured to the bed of a grinding machine. The ring 3 is mounted for free horizontal movement on a rolling-contact carrier 2 of the base 1 and on its upper surface has a member 4 on which the cutting tool 37 to be ground can be secured by clamps 38, the tool being positioned to be aligned with a template 1 held in a holder 29 extending through an opening in the ring 3, and the template engaging a finger 10 mounted on the base 1. An outer ring 30 is mounted by roller bearings 41, 43 on the ring 3. An arm 5 is secured to the outer ring 30 and at its outer end has a pin 19 which, at its lower end, is movable along a guide 18 on the base 1, and, at its upper end, rotatably supports the turntable 6. The pin 19 is also connected by a link 7 to a hand lever 9 movable about a pivot 20 on the base. A spring 25 urges the arm 5 about the pin 19 so that the template 11 engages the finger 10. The guides 22, 26 are secured to the base 1 and slidably receive supports 14, 15 which are rigidly interconnected by a link 17, the support 15 also being connected by a link 8 to the end of the hand lever 9 such that when the lever is moved about its pivot, the pin 19, and hence the arm 5 rings 30, 3, cutter 37 and template, are moved in one direction as the supports are moved in the opposite. The auxiliary template 13 is mounted on one or other of the supports 14, 15 and co-operates with an auxiliary finger 16 mounted in one of a number of holes on the table 6. The finger is maintained in engagement with the template 13 by a member 28 connected to a spring. The table 6 and ring 3 are formed as pulleys around which is a rope 12. The auxiliary template acts, as the main template 11 is moved over the finger 10, through the pin 16 to rotate the table 6 and hence the ring 3 so that the edge of the grinding wheel is normal to the point of the edge being ground. A drawing point 27 is mounted on the table for drawing the shape of the auxiliary template 13 as the main template 11 is moved over the finger 10.

Title: Improvements in or relating to the production of chlorinated rubber products
IPC: C08J9/14
Filed: 1932-06-02
Abstract: Chlorinated rubber is removed from solutions by introducing the solution beneath the surface of an agitated liquid which is immiscible with the solvent and with the rubber, and which is maintained at a temperature above the boiling point of the solvent. According to an example, a solution of chlorinated rubber in carbon tetrachloride is fed into boiling water at the rate of 50 litres per hour, through a 2.5 cm. pipe 40-50 cm. beneath the surface, the water being agitated and its temperature maintained by the injection of steam.  The chlorinated rubber rises to the surface in a porous, spongy, or fibrous condition, all the solvent being evaporated before the surface is reached. The solvent vapour is collected; any hydrochloric acid dissolves in the water to which may be added a base.  Oil-soluble dyes or plasticisers may be added to the solution before evaporation.

Title: Improvements in or relating to television and like systems
IPC: H04N5/073
Filed: 1931-05-29
Abstract: 379,363. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and WALKER, L. E. Q., Pattiswick Rectory, Braintree, Essex. May 29, 1931, No. 15766. [Class 40 (iii).] In a television, picture telegraph or like facsimile system synchronization of the transmitting and receiving apparatus is effected by separating from the complex picture current wave an inherent periodic component which is a function of the scanning line frequency. In practice the frequency of this component would generally be the line scanning frequency, this component frequency being particularly prominent, as represented in Fig. 1, in the picture wave when uneven illumination occurs in scanning, but even when the illumination is substantially uniform, the picture wave includes a component of line frequency, as represented in Fig. 4, or harmonics thereof, this component being separable for synchronization purposes, and suitable receiving arrangements to this end employing filter or selective circuits being illustrated. In one arrangement, Fig. 6, the television signals received at the input terminals I are applied to an amplifier V, and in the output circuit control the fluctuating light source LS. By means of a condenser C and resistance CR the fluctuating voltage in the output circuit is passed to a second amplifier V<1>, the anode circuit of which includes in parallel a choke CH and a filter Z tuned to the desired harmonic component, which is thereby passed to the windings W of the synchronous motor driving the receiver scanning device. In other arrangements, Figs. 7 and 8 (not shown), the amplifying circuit for the television signals received at terminals I is arranged in parallel either with a filter and aperiodic amplifier or with a multistage tuned amplifier designed to select the scanning line frequency.

Filed: 1952-06-23
Abstract: 700,448. Steam turbines. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. June 23, 1952, No. 15773/52. Class 110 (3) A turbine of the radial-flow type has means to collect steam which leaks through packings between stationary and rotary discs 2, 1 and lead it to the exhaust-steam area. This is to prevent the hot leakage steam from impinging on to the inside of casing 9 and causing local heating thereof. High-pressure steam enters an inlet 3 and flows through bladings 4, 5 after which some steam passes through a pipe 6 the remainder flowing through ports 7 to a low-pressure blading 8 and to a condenser. Shields 10 deflect leakage steam from labyrinth packings to the exhaust from blading 8. Additional shields 11 may be fixed to the rotor 1. Fig. 2 shows a modification in which the leakage steam passes through a passage 16 into a collecting chamber 12. Packings 15 are placed in the gap 14 between moving and stationary parts 1, 19 and the passage 16 is shaped to have a suction effect on the gap to prevent undue leakage out through it. Plates 17 are welded to parts 18, 19 acting as supports thereto.

Title: Engine starter
IPC: F02N15/06
Filed: 1945-06-22
Abstract: 583,881. Turning-gear. BENDIX AVIATION CORPORATION. June 22, 1945, No. 15939. Convention date, June 23, 1944. [Class 7 (v)] An engine starter having a pinion 25 slidable into and out of engagement with an engine gear 29 on acceleration of a starter motor has means to hold the pinion in engagement for starting and to release the pinion on deceleration of the starter motor. The starting circuit includes a battery 1 connected through starter switch 4 to two field windings 6, 7 connected to brushes 9, 11 and through the armature to brushes 12, 13. The armature spindle 16 carries a driving head 18 connected through a tension spring 23 to a slidable screw 22 carrying a nut 30 secured to a barrel 31. The opposite end of the barrel is secured to a clutch member 32 coacting with a clutch member 35 on the pinion, the two members being normally separated by a spring 41 by an amount which is limited by a thimble 38 adapted to provide a frictional drag between the pinion and barrel member. A latch pin 42 is mounted in a ring 43 radially slidable in the nut 30 and is urged into engagement with the screw by a plunger. The screw thread has a notch 51 which when the pinion is engaged coacts with the latch pin to lock pinion in mesh. When the latch is tripped by the operator return of the pinion is facilitated by dynamically braking the starter motor in the manner described in U.S.A. Specification 2,353,900. For this purpose the junctions of the field coils and brushes are connected to 'an electromagnet 55 which when energized closes a switch 56 in parallel with the starter switch. The ends of a resistance 58 in this parallel circuit are connected to a coil 67 adapted to close a switch 61 in a line 62 connected to a coil 64 which projects a finger 65 into the path of latch ring 43. In operation, on closing the switch 4 the screw 22 is rotated and the nut 30 traversed to mesh the pinion. When the latter is arrested by washers 10 the further movement of the barrel closes the clutch 32, 35 to transmit the drive to the pinion. During cranking, the voltage between the brushes 9, 11 and earth actuates coil 55 and closes switch 56. When the engine fires acceleration of the pinion disengages clutch 32, 35 leaving the pinion free to overrun while further backward movement of the barrel and nut is prevented by the latch. If the engine now stalls the shaft 16 overtakes the pinion and cranking is resumed. When the engine becomes self operative switch 4 is opened whereupon the voltage drop across resistance 58 closes switch 61 and causes plunger 65 to disengage the latch and permit return of the pinion. At the same time the earth connection through line 62, 63 short-circuits the armature and produces dynamic braking thereof thereby facilitating pinion disengagement. Switches 56 and 61 then reopen and the finger 65 returns to idle position.
