Title: Improvements relating to sound recording apparatus
IPC: G11B3/36
Filed: 1931-01-02
Abstract: 370,418. Recording sound. COLE, Ltd., E. K., Ekco Works, Southend-on-Sea, KNIPE, A. R., 5, Southsea Avenue, and MARTIN, A. W., 1, Thames Close, both in Leigh-on-Sea. Jan. 2, 1931, No. 214. [Class 40 (ii).] In sound-recording apparatus of the kind in which a recorder is traversed across a blank disc on a turntable by means of a screwthreaded spindle mounted in a frame and driven by a friction wheel engaging the turntable or disc, a driving blade attached to the recorder or to the support therefor is constructed as or mounted on a resilient metal strip, which is adapted to engage with the screw-thread in such a manner that the weight of the recording device imposes no considerable load on the spindle, but is borne wholly or mainly by the frame or the disc. The apparatus shown in Figs. 2 and 4, adapted for attachment to an ordinary gramophone, comprises a frame formed by two end-pieces 5, 9 supporting a screwed spindle 13 and a rod 8, the part 5 having a socket 6 which fits loosely over the turntable spindle, while the other end-piece consists of a yoke 9 pivoted at 10 to a pin 11, which is pivotally mounted in a socket member 12 on the motor-board. The spindle 13 is carried on bearings 14, and is rotated by gears 16, 17 and a friction-wheel 18, the latter being mounted on the member 5, so as to be in contact with the record disc 4 on the turntable. The recorder 21, which is an electromagnetic device adapted to be connected to a suitable circuit in a wireless receiver or microphone apparatus, is connected by plug and socket contacts 22 to a carriage 20, which is slidably mounted on the rod 8. The carriage is provided with a driving blade 25 formed as a resilient metal strip which engages laterally with the screw thread of the spindle 13. The pitch of the spiral trace formed by the recorder can be varied by providing arrangements for adjusting the position of the driving wheel 18 relatively to the turntable spindle. This wheel carries a tyre 19, and the portion of the record blank engaged thereby may be roughened. Fig. 7 shows a modification in which the recorder 33 is mounted on an ordinary gramophone tone-arm 34. The driving blade 25, engaging with the feed-screw 13, is in this case mounted on or formed as the end of a resilient arm, which is adjustably mounted on the tone-arm by a clamp 38. The spindle 13 is supported by a frame 35, one end of which is mounted in trunnions 36, the other end being adapted to fit over the turntable spindle (not shown). The friction wheel 18 may be mounted, as shown, directly on the spindle 1.3. In order to reproduce from records made by the apparatus shown in Fig. 2, the feed mechanism for the recording device may be removed by withdrawing the pin 11 from its socket, and a bracket 27 pivotally supporting an arm 26 for carrying the device 21 may be substituted as shown in Fig. 5, a fibre needle 32 being then used to enable the device 21 to serve as a pick-up. Terminals 31 are connected through plug and socket contacts 29 and a cable 28 to the pin and socket contacts 22 on the pick-up.

Title: Improvements in or relating to machines for mixing concrete and other substances
IPC: B28C7/12
Filed: 1935-01-05
Abstract: 437,153. Concrete-mixers. PARKER, Ltd., F., and PARKER, F. W., Catherine Street Extension, Leicester. Jan. 5, 1935, No. 437. [Class 86] In a concrete-mixer in which the operation of the pivoted loading shoot effects the supply of a definite amount of water to the drum, the water is supplied from a tank which discharges by tipping about a longitudinal axis, the tank being also pivotally movable about an external transverse axis against the influence of a counterweight to control a valve which charges the tank. As shown, the mixer has a tilting drum mounted between frame members 1, Fig. 2, and the water supply is mounted between cheeks 11, 12 carried therby. The tank 15 is supported by bearings 17, 18, the former being carried by a counterweighted lever 19, Fig. 1, while the latter is carried by a hollow tube 23 which serves as the water supply and is pivoted at 24 to the cheek 12. The tank is tilted by means of a link 36 operated by an arm 35 on the shaft 10 on which the charging shoot 9 is mounted, and discharges into a fixed shoot 32 leading in turn to the mouth of the drum. The tank is filled from a branch 26 fitted with a valve 27 controlled by a lever 29 adapted to abut against an adjustable stop 30. When the tank is empty the counterweighted arm 19 lifts it about the pivot 24 and allows the valve 27 to open. As the tank fills it falls and the valve is shut by the engagement of the abutment 30 with the valve lever 29. A spring 41 is provided between the tank and the cheek 11 to ensure that the tank does not lift about the pivot 24 till it has been tipped back to its filling position.

Reference has been directed by the Comptroller to Specification 690,592.
Patent GB-726831-A (GB)
Title: Improvements in terephthalic acid synthesis
IPC: C07C51/27
Filed: 1953-01-07
Abstract: Terephthalic acid is made by refluxing a mixture of p-xylylene dichloride, nitric acid of 70-100 per cent strength and a saturated aliphatic monocarboxylic acid of 2-6 carbon atoms; the latter holds the reactants in solution but causes precipitation of the terephthalic acid as formed.  The process is preferably carried out at a pressure of 1/3 -2 atmospheres above normal.  The nitric acid is used in amounts of 1.5-3 times and the carboxylic acid (preferably acetic) 2.5-8 times the weight of p-xylylene dichloride.  The latter may be a crude mixture of chloromethylbenzenes (containing also the o-isomer) obtained by chloromethylating benzyl chloride; there are then obtained as by-products phthalic acid (or anhydride) and acids of the diphenylmethane series.  After separation of the terephthalic acid the solvent may be recycled and used again, fortified with nitric acid and/or acyl anhydride.  Examples are given of the process.  The terephthalic acid may be converted into its dimethyl ester.  Specifications 623,836 and 644,707 are referred to.

Title: Magnetic key operated lock
Inventor: SEDLEY BRUCE SAMUEL
IPC: E05B47/00
Filed: 1995-05-04
Abstract: In a magnetic key operated lock, a slide member carries a plurality of wheels in which are mounted magnetic pins. The position of the pins forms part of a code of the lock. The wheels are caused to rotate by insertion of a code changing key, which has a code for unlocking the lock, and moving the slide member. As the slide member moves, one of the pins which is repelled by the particular code changing key abuts a stop, which thus causes the respective wheel, and so the other wheels, to rotate. By having wheels of two different diameters, the smaller wheels can be made to rotate more than once before a code is repeated. The stops are formed by pressing a tang from a stationary wall in the lock.
