Abstract: 616,469. Gramophones. MORTIMER, E. W., WILKINS, E. W., and GARRARD ENGINEERING & MANUFACTURING CO., Ltd. Sept. 4, 1946, No. 26616. [Class 40 (ii)] In a gramophone, the pick-up 1 is mounted on a movable carriage 7 which slides along a rod 8 carried by an over-arm 2 which is movable, about a pin 3 on a fixture 4, under the control of the movement of the lid of the gramophone, whereby the pick-up 1, after being lifted from the record by a bar 9 on the over-arm 2, slides by gravity with carriage 7 on the rod 8 to its starting position ready for lowering on to the next record to be played, a stop-member 44 and sliding rod 42, Figs. 3 and 4, being provided for automatically setting the starting position according to whether a 10 or 12 inch record is to be played. The stop-member 44 and rod 42, which return by gravity to the setting for a 12 inch record when the over-arm 2 is lifted, is enabled to be reset for a 10 inch record, after re-lowering of the over-arm 2 by means of a lever 37 according to the position of a feeler-member 35 on an arm 33 pivoted at a fixed point 34 and supported by a spring 36. The feeler-member 35 is located so that it may contact a 12 inch record but not a 10 inch record. When a 12 inch record is placed on the turn-table, the engagement of the feeler-member 35 with the record causes the lever 33 to be depressed so that a pin 39 on lever 37 is freed from a recess 40 and engages a surface 41 and holds the feelermember 35 out of contact with the record, the upper end of the lever 37 being meanwhile held out of engagement with the end of the rod 42. When however a 10 inch record is placed on the turn-table, the lever 33 remains in its upper position and the lever 37 remains in the locked position, by means of the pin 39 and recess 40, a position to which it has been returned by the lifting of the over-arm 2. When the over-arm 2 is re-lowered the upper end of the lever 37 urges the rod 42 and the stop-member 44 to the starting position for a 10-inch record, Fig. 3. During lowering of the over-arm 2, a bell-crank lever 16, Fig. 7, engages a switch lever 17 carrying a contact 18 which is brought into engagement with spring contacts 19, and closes the circuit of the turn-table motor. Secondary switch contacts 25, 26, Fig. 4, are provided, which are closed by the pressure of a record on the turn-table acting on a plunger 30, and are connected in series with the above-mentioned primary switch, so that the motor circuit is not completed in the absence of a record on the turn-table. When the pick-up 1 reaches the run-off groove of the record the carriage 7 comes into contact with a rod 14 coupled by a block 13 to the end of a rod 11 passing through the rod 8 and having a collar 12, Fig. 5, at its other end which pulls the limb 15 of the bellcrank lever 16 so that the switch-lever 17 is released and the motor circuit interrupted.

Title: Improvements in or relating to vapour vacuum pumps or other apparatus employing vapour nozzles
Inventor: POWER BASIL DIXON
IPC: F04F9/00
Filed: 1956-09-03
Abstract: 815,052. Diffusion pumps. EDWARDS HIGH VACUUM Ltd. Aug. 23, 1957 [Sept. 3, 1956], No. 26899/56. Class 71. In a diffusion pump condensable vapour flows through the nozzles under conditions such that an undesirable boundary layer occurs or tends to occur, this layer tending to thicken towards the nozzle exit and causing a random cloud of molecules to pour out from the nozzle many of which flow in a backstreaming direction towards the container being evacuated. To prevent this undesirable condition a temperature gradient is established along the wall of the nozzle from the entry region, or from a region intermediate the entry and exit regions, to the exist region, the temperature gradient being such that vapour molecules tending to form the boundary layer are condensed, the resulting liquid being sufficiently cooled by the time it reaches the nozzle lip that it has too low a vapour pressure to contribute significantly to backstreaming from the pump. In the embodiment shown in Fig. 2, the nozzle lip 16 has a high thermal conductivity, conveniently formed of a copper ring, which is connected by struts 17 of high thermal conductivity to a band 18 secured to the cooling surface of the pump. The middle region 19 of the nozzle is made from a thin material of low thermal conductivity, such as stainless steel, and is secured to the lip 16 and the nozzle crown 20 by any suitable means such as brazing. In operation the temperature of the nozzle crown is probably 180-220‹C. and the nozzle lip 30-40‹C. In a modified form a second ring similar to the lip 16 is in contact with the nozzle part 19 and a strut connects this ring to the strut 17. When the pump has an inner condensing wall the nozzle can be formed as an annular nozzle the inner lip being connected to the inner condensing wall and the outer lip to the outer wall. In the embodiment shown in Fig. 8, the lip is not formed as separate member, a copper ring 33 being brazed to the lip of the stainless steel nozzle. A re-entrant portion 36 is formed in the nozzle to provide a lengthening of the conducting path. This reentrant portion may be omitted or a separate inner portion may be formed so that controlled condensation only takes place only during later stages of vapour expansion. Specifications 700,978, 751,878 and 815,051 are referred to.

Ester condensation products.-In the manufacture of cellulose ester or ether coating compositions, a synthetic resin, prepared by heating a polyhydric alcohol with an organic acid and cottonseed oil or derivative thereof, is added. The polyhydric alcohol may be a glycol, e.g. ethylene glycol, or glycerol or pentaerythritol, and the organic acid may be polybasic, e.g. phthalic, camphoric, diphenic or citric acid, or a fatty acid, e.g. palmitic acid, or an aromatic monobasic acid, e.g. benzoic acid, or a mixture of these acids. Heat treated acids derived from cotton-seed oil may replace the oil itself, e.g. those obtained by distilling in vacuo, the acids obtained from an acidulated cotton-seed soap stock solution. In an example, glycerol is heated with phthalic anhydride and cotton-seed oil fatty acids at 240‹ C. for 4 hours. The formation of insoluble polymers is prevented by a temperature control, e.g. by cooling coils, or by addition of reaction modifiers, e.g. urea, or alpha- or #-naphthol.
