Title: Improvements in and relating to bakers' machinery
Inventor: SMITH HAROLD AUSTIN
IPC: A21C15/00
Filed: 1952-01-21
Abstract: 729,040. Endless conveyers. PELKMAN BROS., Ltd. April 21, 1953 [Jan. 21, 1952], No. 1685/52. Class 78 (1). [Also in Group XL (b)] In a baker's machine comprising a conveyer for carrying loaves or dough pieces, two detecting systems are employed, one responsive to the passage of a load and the other to passage of a loaf or part of the conveyer so that incorrect positioning of a loaf on the conveyer brings a safety device into operation or operates an alarm signal. One embodiment comprises two photo-electric cells 22, 23, spaced apart by a standard distance slightly greater than the desired loaf breadth, on one side of the conveyer illuminated respectively by two lamps 20, 21 the opposite side. Passing loaves block the cells, but only one at a time provided they are perpendicular to the line of motion, of standard size, and spaced apart by a distance greater than the width of a loaf. If any of these conditions is violated the cells, which hold closed parallel switches 24, 25 in the motor circuit, are simultaneously blocked and the motor stops. An alternative arrangement uses only one source and photo-cell with two mirrors, one forming a virtual source and the other directing light from one source on to the cell which is directly illuminated by the other, the output of the cell being sufficient to hold closed a single switch in the motor supply when illuminated by one cell. The outputs of the cells may be connected in parallel to an amplifier valve, the output of which closes a switch making a circuit to a solenoid, energized by the motor supply, which controls a switch in the supply so that the supply is broken when both cells are blocked. In an embodiment using a mechanical conveyer-operated switch 38, Fig. 3, this switches in a matched impedance 40 across the amplifier input to replace the cell and thus maintain the output substantially constant. The motor is open circuited when the switch is open and the cell blocked.

Abstract: 371,390. Prepayment mechanism for gas meters &c. GROVES, W. W., 30, Southampton Buildings, London.-(Pintsch Akt.-Ges., J.; 71, Andreasstrasse, Berlin.) Jan. 19, 1931, No. 1725. [Class 27.] Coin action, mechanical-connection ; coinslit closing- devices ; fraud preventing.-In a coin-freed mechanism, particularly for gas meters, having an epicyclic gear driven by the coin and meter mechanisms respectively to open and close the valve, a coin 31, Fig. 4, inserted through a slit 35 to a slotted shaft 5 drives a ratchet wheel 13 loose on the shaft 4 of the epicyclic quantity mechanism, which includes planet wheels 10, 11 mounted in a radius arm 8 carried by the shaft. A spring- controlled lever 26 pivoted at 28 normally holds the coin wheel 13, and is raised momentarily by the coin being forced past a projection 30, which prevents the coin from being withdrawn. The lever 26 has an abutment or lug 34 which guides the coin during insertion and closes the coin slit while the wheel 13 is being actuated. A projection 32 on the arm 8 moves the lever 26, when the maximum number of coin has been inserted, and causes the lug 34 to close the coin slit until some of the gas prepaid has been consumed. A yoke 36 allows only a coin of the proper size to pass. Gas, supplying by meter; indicators.-The planet wheels 10, 11, Fig. 6, mesh with sun wheels 14, 16 carried respectively by a meterdriven wheel 12 and a sleeve 16a connected to the coin wheel 13 by a friction clutch 7. The wheels 14, 16 are loose on the shaft 4 which is provided with a cam disc 18 for actuating a valve-operating arm 19, and a pointer moving over a dial to indicate the number of coins standing to the credit of the consumer. This pointer can move past zero to the negative side of the dial scale, in the case of a leaky valve, until a stop 20 on the disc 18 meets a fixed abutment 21. Thereafter the clutch 7 slips and prevents damage. The amount of escaped gas indicated on the negative side of the dial must be paid for by the insertion of coins before the coins become effective to open again the valve.

Title: Improvements in artificial respiration apparatus
IPC: A61M16/00
Filed: 1954-01-21
Abstract: 746,887. Artificial respiration apparatus. CONITECH, Ltd. Jan. 21, 1954 [March 9, 1953; Oct. 30, 1953], No. 1824/54. Class 81(2). A valve device for connection to a respiratory air pump enables air to be delivered to a patient's lungs for inhalation, exhalation being performed naturally. The appliance is primarily intended for use with the pump of a cuirass, or iron lung, to supply air directly into the lungs when the cuirass or iron lung is not in use. Air from the pump is admitted through a pipe 30 and passes through a filter 78 to an annular aperture 24, where it lifts an annular valve member 22 off its seating 44 so that air passes through its central aperture to the outlet conduit 38, which is connected to a mouthpiece. During the suction stroke of the pump the valve member 22 drops and closes the aperture 24, but at the same time it opens the end of the tube 40 so that the patient can exhale naturally through orifices 26. During this suction stroke, also, a valve member 50, in the bottom of the casing 80, is lifted off its seating to allow air to enter the pump. The maximum positive pressure is limited by a weighted valve member 64 which normally closes a chamber 60 in communication with the conduit 38 through apertures 58. It is also proposed to replace the weighted release valve 64 by a spring-loaded valve, see Fig. 6 (not shown), the pressure of which may be adjustable. In this modified arrangement also, provision is made for a central pressure transmitting tube of the type used with a gauge as in Specification 740,192 and for the connection of the valve housing to the pump housing through a length of flexible tubing.
Patent GB-1013205-A (GB)
Title: Polymerization processes
IPC: C08F279/02
Filed: 1964-01-15
Abstract: Polymerizable rubber-in-monomer solutions are made by contacting a conjugated diolefine with lithium or a hydrocarbyl lithium catalyst in a diluent non-polar medium boiling below 130 DEG  C. to form a rubbery polymer, adding to the medium a monovinylidene aromatic hydrocarbon and, either before or after said addition, deactivating the reaction mixture, and stripping from the resulting mixture at least the greater part of those ingredients which boil below the boiling point of the monovinylidene aromatic hydrocarbon.  When the monovinylidene aromatic hydrocarbon is added to the diolefine reaction mixture prior to its deactivation, block copolymerization takes place between the polydiolefin and a portion of the monovinylidene hydrocarbon.  The products are rubber-in-monomer solutions which may be polymerized as such, or after the addition of natural of synthetic rubbers or other monomers, e.g. styrene and its derivatives and acrylic and methacrylic acids, esters, amides and nitriles. The polymerization of the rubber-in-monomer solutions may be effected by mass, suspension or mass-suspension techniques. The examples describe: (1) polymerizing butadiene in cyclohexane in the presence of n-butyllithium, deactivating the polymer with butanol, adding styrene, and removing solvent and unreacted butadiene by distillation to yield a rubber-in-monomer solution which is polymerized with the aid of di-tert.-butyl peroxide by a mass-suspension technique; (2) as in (1), but using a styrene-alpha-methylstyrene monomer mixture; (3) as in (1), but using an excess of butadiene as the reaction diluent in place of cyclohexane (4) as in (1), but deactivating the polymer after the addition of styrene, whereby a portion of the styrene forms a block polymer, and adding alpha-methylstyrene to the mixture after deactivation; (5) as in (1), but adding a mixture of polybutadiene, styrene and acrylonitrile to the rubber in monomer solution.  The process of Example (1) may also be carried out in the presence of lithium metal, ethyl lithium, 2-ethylhexyl lithium, benzyl lithium and ethylene dilithium as catalysts. Specification 833,571 is referred to.

Title: Improvements in or relating to curtain suspensions, bracelets, necklaces, girdles and the like articles
IPC: A47H1/18
Filed: 1946-01-19
Abstract: 604,261. Clothes lines; suspending curtains. MARSHALL, H. S. Jan. 19, 1946, Nos. 1892 and 29137. [Class 52(v)] [Also in Groups VII and XXV] Flexible rod material for clothes lines, suspending curtains and the like. comprises a length of flexible plastic sleeving containing an inherently resilient core serving to maintain the sleeving distended. The sleeving may be formed from an elastomeric compound comprising a vinyl chloride acetate resin compounded with a plasticiser. A metallic core composed of one or more strands of tempered steel wire, or one or more lengths of helically coiled wire, is used. Preferably the core c is fed, with a uniform clearance all round it, through a die, the plastic being flowed under pressure into the clearance to form the sleeve a. which adheres to the core c and penetrates into the helical spaces b between adjacent turns of the coil, so that the inner surface of the sleeve a is helically formed, and expands and contracts with the coil while the outer surface remains smooth. In this way when the core is extended it remains fully covered by the sleeve, thus dispensing with independent means for holding the two parts together. The ends may be joined by binding, or by interengaging releasable fasteners, e.g. by male and female coupling sleeves each providing a cuff which covers the end of the sleeve a.
