Title: Process of concentrating aqueous rubber and like dispersions
IPC: C08C1/12
Filed: 1936-03-27
Abstract: 461,216. Concentrating latex. METALLGES. AKT.-GES. March 27, 1936, No. 9151. Convention date, April 3, 1935. [Class 70] In the concentration of aqueous rubber or like dispersions by evaporation under reduced pressure'in the presence of volatile stabilizers such as ammonia and/or volatile amines, the stabilizer escaping with the water vapour is separated from at least the major part of the water vapour and recovered in utilizable form. In the form shown, latex from the vessel a is forced by the pump c through the preheater b and nozzle d back to the vessel a, where some of the water and volatile stabilizer is evaporated off. The latex, which may also contain other stabilizers such as protective colloids or alkali hydroxides, is circulated through the system a-c-b-d-a until the desired concentration is attained, as described in Specifications 382,235 and 393,732. The vapours pass through a water-cooled condenser f, maintained at or just below the dew-point, so that the bulk of the water condenses and passes off through g, while the bulk of the stabilizer is passed by the pump i to the absorber k, in which it is absorbed by water which circulates through the cooler o. The stabilizer may then be stored or returned to the process. The absorber may be replaced by a counterflow washer, or a water-ring pump may be used, the sealing water being utilized as absorption liquid. The liquid leaving condenser f may be heated, if desired in the form of spray, to drive off residual stabilizer, which is passed to the absorber. The solution from the absorber may be treated to separate ammonia vapour by spraying in a partial vacuum. Specification 255,014, [Class 70], also is referred to.

Abstract: 843,047. Change-speed control. UHER, E. March 21, 1958 [March 27, 1957]; No. 9158/58. Class 80 (2). An engine-driven pump discharging through a fixed orifice in a closed circuit determines the pressure, balanced against a pulley spring, to provide speed-responsive ratio shift in an expanding pulley gear. An engine 3 drives a pump 1 drawing fluid from a tank 5 and returning the fluid through an orifice 7 to provide speed proportionate pressure in a pipe 8 leading to the bore 9 of a shaft 10 carrying an expanding pulley 12, 14 and a sprocket 18. The sprocket 18 drives a vehicle 22 wheel by chain 19 and sprocket 20. The movable flange 12 of the pulley 12, 14 is urged towards the fixed flange 14 by a spring 23 whose action is opposed by the fluid pressure on a piston 11 connected to the flange 12 by a pin 13. The pulley 26, 27 is driven from the engine 3 through a speedresponsive centrifugal clutch 33 and has its movable flange 27 urged by a spring 31 of less strength than the spring 23. A V-belt 25 connects the two pulleys. In a modification an adjustable by-pass is provided across the fixed orifice to vary the speed-responsive characteristics and a spring- loaded relief valve is connected across the pump. The adjustable valve may comprise a needle valve having a predetermined minimum flow, retraction of the needle by manual means providing increased flow, the needle valve thus providing the characteristics of both the fixed and adjustable orifices. The needle valve may be controlled in accordance with engine load or temperature.

Title: Transmission system comprising a transmitter and a receiver for the transmission of information in a prescribed frequency band
IPC: H04J3/06
Filed: 1969-02-20
Abstract: 1,212,340. Automatic frequency and phase control; pulse signalling; data transmission systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 20 Feb., 1969 [23 Feb., 1968], No. 9177/69. Addition to 1,201,923. Headings H3A, H4L and H4P. In a signal transmission system in which, as in the parent Specification, a periodic pulse pattern non-correlated with the main information signal is transmitted simultaneously with the information and in the same frequency band and is used at the receiver as an address or synchronizing signal, a regenerative repeater is used in the signal transmission path. The arrangement is similar to that at the receiver, comprising regenerative repeater 83, Fig. 2, driven by pulses derived from shift register 10<SP>11</SP>, the pulse train from the shift register being added to the output from regenerative repeater 83 in adder 87. AND gate 53<SP>11</SP> is coupled to counter 92, driven by clock pulse generator 16<SP>11</SP>, whereby in a pulse time-division multiplex system a chosen channel may be dropped off. For this purpose the transmission channel is coupled via two-phase rectifier 97 to AND gate 93, the second input of which is derived from counter 92 and the output of which feeds memory element 93. The two-phase rectifier 97 is necessary to reconvert the signal to a bivalent form since the original bivalent signal pulses are converted at the transmitter to trivalent pulses, the conversion circuit comprising a linear difference producer 72, Fig. 1, to which the pulses are applied on the one hand directly and on the other hand via shift register 73 operated by clock-pulse generator 16, the linear difference producer 72 being preceded by modulo-2-adder 71 the second input of which is is connected to the output of shift register 73.
