Abstract: 444,833. Centrifugal machines. LORING, F. H., 7, Elliott's Place, Islington, London. Dec. 3, 1934, No. 34658. [Class 23] [See also Group XXIX] A centrifugal apparatus for spraying or impregnating granular material with liquid comprises a vertical tubular shaft 2, through which liquid is supplied, having at its lower end a porous or perforated basket 1 and having externally a restricted housing through which the powdered material is fed past the basket. The granular material is fed down a shoot 31 into a hopper 17 and thence to the conical hopper 20 where it passes a cone or disc 18, provided with helical blades, adjustably mounted on the shaft 2 which feeds it past the sprayer basket. Within the basket 1 is a perforated cup 13 from which liquid is sprayed on to the felt liner 11 of the basket. The cup may be conical as shown or formed with vertical sides. The cup may be filled with breeze, open-meshed material or wires to assist in spreading the liquid. The basket may carry a saucer 27, the rim 24 of which may be turned up or down and notched to atomize any drip. Blades 25 may be carried by the basket to assist in swirling the material. The upper bearing may be provided with a cap to prevent access of leakage from the pipe 12. The bearings are provided with felt pads 32 to prevent access of dust and covered by plates 33, 33a, 34, 35.

Title: Radiation analysis
Inventor: MUNDAY CHARLES WALTER
IPC: G01N21/35
Filed: 1953-12-15
Abstract: 781,972. Radiation analysers. DISTILLERS CO., Ltd. Dec. 2, 1954 [Dec. 15, 1953], No. 34915/53. Class 40 (3). An infra-red liquid analyser of known type uses filters or selective detectors to limit the infra-red radiation used to between 0.8 and 2.7 Á at which the absorption by liquids is said to be much reduced and thus to permit the use of absorption cells which do not have to be of excessive thinness. The analysis of various substances by this method is mentioned and as filters are suggested germanium of a thickness of from 0.5 to 0.6 which absorbs all radiation below 1.0 combined with a glass filter which absorbs radiation above 3.5 Á. A multi-layer interference filter transmitting only radiation in the wavelength 930-990 mÁ is also suggested. The infra-red source should be at such a temperature as to give its maximum output at the wavelengths concerned should be used and the detector also should be of maximum sensitivity in this range. Thus lead sulphide and thallium sulphide detectors are said to be suitable, while for wavelengths of about 960 mÁ an image converter combined with a photo-multiplier is advantageous.

Abstract: 1523895 Pessaries and pessary inserters MEDEVICE CO 22 Aug 1975 [28 Aug 1974] 35031/75 Heading A5R [Also in Division F2] A contraceptive device 20 comprises a silicone cup 22 having a base portion 32 and a lip portion 34, and a valve mechanism 56 comprising a circular silicone diaphragm 58 having ports 70 therein and being attached by adhesive about its periphery 60 to the bottom surface 64 of the cup and covering a passageway 48, the ports being in offset relationship to the passageways. The cup is positioned about the cervix, Fig. 3 (not shown), with O-ring 30 in groove 38 as shown in Fig. 2. The O-ring is then moved to groove 40 to reduce the circumference of the lip portion 34 and clamp the cap to the cervix, notches 36 allowing the reduction is circumference. Bead formations 44 and 46 assist in keeping the cap in place. Valve mechanism 56 acts as a one-way valve allowing liquid to flow out but not in. In variations the diaphragm of the valve may have differing shapes, e.g. rectangular or butterfly, Figs. 9-11 (not shown). The clamping to the cervix may optionally be assisted by a liquid-filled bladder or a sealant, e.g. silicone or denture-type adhesives, Figs. 7 and 8 (not shown). Alternatively, the clamping may be achieved by the resilience of the cup which is then applied using an applicator, Figs. 4- 6a and 13-15 (not shown).

Abstract: 1,065,660. Phase modulation. STANDARD TELEPHONES & CABLES Ltd. Aug. 28. 1964, No. 35348/64. Heading H3R. In a " push-pull " phase modulator, identical single sideband signals are added respectively to two local carrier waves of identical frequency C1 but opposite phase to produce two phase modulated waves; then one is frequency changed by an auxiliary carrier signal and combined with the other phase modulated wave to produce an output at the auxiliary carrier frequency C2 of doubled phase deviation and with second order non-linear distortion products eliminated. The system may be used in a radio relay repeater, the auxiliary carrier being the incoming signal, and the phase modulation adding a further signal in a modulation frequency band not already used in the incoming wave. The system may be used in a satellite receiving several blocks of S.S.B. telephone channels not overlapping frequency, the blocks being applied to a local carrier to produce a phase modulated wave as above. Moreover a pair of phase modulated outputs so produced but having non-overlapping modulating signals may be combined by frequency changing into a single phase modulated satellite output.

Abstract: 1,107,988. Token-freed apparatus. TECHNICAL DEVELOPMENT CAPITAL Ltd. 20 Aug., 1965 [28 Aug., 1964], No. 35440/64. Heading G4V. A token-freed self-service apparatus ha<SP>s</SP> sensing means operated by coded information on a token identifying it as forming part of the apparatus, the token also carrying an identification code of a particular location in the apparatus, and means for selecting and delivering goods from an identified location after the sensing means has freed the apparatus for operation to allow access to the goods. The apparatus may be a bank safe deposit or leftluggage locker or the goods may be, e.g., films previously left for processing, but is particularly described with reference to a kiosk for collection of dirty clothes and subsequent delivery of cleaned clothes. The token is preferably of synthetic plastics with the coded information formed either as magnetic signals on a magnetizable layer or as part of a printed electric circuit. The identification code may be formed similarly for automatic operation or as a printed number for customer operation, e.g. by dialling the number. In operation a customer inserts appropriate coins or discs and presses a button whereupon (a) a token is issued, (b) a receipt is printed and issued, and (c) power is switched to the electrical systems. The token is inserted in a slot (8) (Fig. 1, not shown) to be read by the sensing means and after checking, a fast motor 31 is freed to drive a link conveyer carrying hangers 29 each in a groove formed by projections 28 on a link 26. When the link identified by the token is adjacent a positioner 39 the motor 31 is cut out and a slower motor 35 moves the conveyer until the selected groove is opposite the end 41 of a rail 40. A trolley 49 is then moved by motor 44 to pick the hanger off the conveyer and carry it into a drum 53. The drum is rotated until an aperture 57 is coincident with an aperture in the kiosk wall and the customer places dirty clothes in a bag 30 and recovers the token. The drum is returned and the trolley reversed, the hanger being released by a member 52 so as to be caught by a transfer rail 71. To recover the cleaned clothes a similar procedure is followed except that the token is inserted in a different slot (9) to be retained in the apparatus for future use. The slow link movement may be replaced by providing selectively operated arms 50. In the case of leftluggage lockers, the storage area may be located above the delivery chamber.
