Abstract: 265,269. Automatic Telephone Manufacturing Co., Ltd., and Woodland, C. R. Oct. 20, 1925. Jacks and plugs.-In a multi-contact jack and plug connector particular suitable for routine testing of automatic telephone switching apparatus, the sides of the frames of the jack and plug are detachable and each arranged to carry part of the spring assembly in order that access may be readily had to the springs or their capacity increased. The plug is held in position when inserted by members independent of and additional to the contact springs. Figs. 1 and 2 show the jack which consists of two L-shaped brackets 1 held together by side plates 7 which support sideby-side two sets of springs 3. The springs are made shorter than the legs of the members 1 to provide room for connecting up a cable and to protect the springs. A dust cover may be placed over the jack. The plug, Figs. 4 and 5, consists of a frame with two legs 12 which when the plug is inserted fit between the legs of the jack members 1 to hold the plug in position. A projection 20, Fig. 4, on one of the legs 12 engages a slot 8, Fig. 1, in the jack to ensure that the plug is correctly inserted. Two spring groups 10 are separately mounted by means of screws 13 on detachable side plates 14, 23 of the plug, the frame of which is made longer than the spring assembly to protect the latter and to provide room for connecting up a cable which enters the plug through a bushed nut 19.
Patent GB-263115-A (GB)
Abstract: 263,115. Soc. du Film en Couleurs Keller-Dorian, and Richard, P. A. Dec. 19, 1925, [Convention date]. Colour photography.-Colour-record component images for additive or subtractive colour photography or kinematography are produced by selective projection-printing from a multicolour record image taken on a film provided with a screen of lenticular refracting elements. The embossed film A bearing, for example, a tricolour record image is illuminated by a light-source S, and the image is projected by a lens system R upon an ordinary film B. If this film is coated with a panchromatic emulsion, a colour filter X of the same kind as that used in the taking camera is placed at the optical centre of the lens system, having, for example, blue, green, and red sectors or zones, and prints, each representing one of the three colours, are made on the film B in successive areas, as the film is fed intermittently through the apparatus, by masking at each printing operation the appropriate portions of the colour filter, or by disposing uniformly coloured' selecting screens Y in turn between the lens system and the film. If the film B is coated with an ordinary emulsion, the colour filter X is replaced by a circular mask having cut-out portions corresponding to the sectors or zones of the filter. and each cut-out portion is uncovered in turn to make the three prints in successive areas as the film B is fed intermittently through the apparatus. The Specification as open to inspection under Sect. 91 (3) (a) states also that the network which appears on the selected images may be removed with the aid of suitably collimated projecting apparatus. This subject-matter does not appear in the Specification as accepted.

[Also in Group XXXV] Relates to a magnetic tape-recorder and reproducer in which a capstan is driven at a constant speed during recording and at a servo-controlled speed during reproduction. With the switch 36 thrown to the " record " position, control track head 25 is connected through amplifier 38 to A.C. source 39 providing a reference frequency signal developed at a pick-off of a head drum arrangement 40. A control track 37 is recorded along the tape and the signal is related to the speed of the heads. A source 41 of D.C. is connected to brake 42, and is also connected to inverter 43 driving synchronous motor 44 which is coupled through speed reducer 46 and differential 47 to capstan 24. A frequency standard source 48 is connected to the inverter 43. With the switch 36 in the " reproduce " position, the head 25 is connected through amplifier 51 to phasecomparator 52 which also receives a signal from the source 39. The error signal is passed through servo compensator 53 and amplifier 54 to servomotor 56 which is coupled to the differential 47 through speed reducer 57. Thus the speed of capstan 24, as driven by the synchronous motor 44, is varied by the servomotor 56 in response to the error signals. The brake 42 operates on the servo controlled structure during the recording operation, during which period the servomotor is disconnected and has no effect on the speed of the capstan. As shown, the motor 44 is coupled to shaft 71 through a speed-reducing belt drive 68, 73, 72, the angular velocity of the shaft 71 being further reduced by belt drive 74, 77, 76. The pulley 76 drives the capstan 24. The servomotor 56 drives pulley 99 through pulley 96 and belt 101. The pulley 99 has ballbearings 103 spaced from its centre and associated with the shaft 71. The solenoid-operated brake 42 acts upon the rim of the pulley 99, and the belts 73, 77 are associated with tension arms. Specifications 812,479 and 883,637 are referred to.

Abstract: 1384838 Freeze drying SMITHERM INDUSTRIES Inc 6 June 1973 [31 July 1972] 27028/73 Heading F4G A method of freeze drying a product comprises the steps of introducing the product to be dried into a zone maintained at a pressure which is less than atmospheric but is sufficiently high to suppress vaporization of volatile constituents of the product, spreading the product into a layer, freezing the product in the layer, reducing the pressure on the frozen product to a pressure below 4À6 mm. of mercury, and heating the product to effect sublimation of water from the product and thereby reduce its moisture content. Apparatus for carrying out the method comprises a freezing compartment 28 and a drying compartment 30 through which the product is passed in succession by means of endless belt conveyers 32, 34, 36. Product is fed on to the conveyers through a valve controlled main conduit 58 and branch conduits 61, 62, 64 and headers 72, 74, 76 and is frozen to the conveyers in compartment 28 by freezers 82 to which a coolant, such as lithium, is circulated. The pressure in compartment 28 is maintained at the required level by water vapour from a reservoir 98 in which the water is heated by a resistance heater 104. The frozen product is passed through apertures 50, in a partition 26 into drying compartment 30 which is maintained at a pressure below 4À6 mm. mercury by a vacuum pump connected thereto by way of line 188. Drying is completed by sublimation of the water using radiant heaters or radiators 106, 108, the final product passing via a main conduit 158 to hoppers 160, 162. The conveyers are advanced by rolls 44, 46, the latter being cooled by a refrigerant. Instead of a reservoir 98 being used to supply water vapour in compartment 28, steam jets may be used. The vacuum pump is connected to the line 188 by way of a condenser for removing moisture therein.
