Title: Compositions containing cement and highly polymeric substances
IPC: C04B28/06
Filed: 1948-03-09
Abstract: Compositions for floor coverings and ship's decks comprise cement and an aqueous dispersion of a natural or synthetic high molecular addition polymer containing alkali-degraded casein as stabilizing agent.  The casein is preferably prepared by adding casein slowly to boiling aqueous sodium hydroxide solution and then continuing the boiling for about 30 minutes until the viscosity of the solution was considerably reduced.  The cooled mixture may be mixed with an unstable natural rubber latex, a GR-S latex, or a polyvinyl acetate latex, with the optional addition of wood chippings and then with cement.  Such a mixture remains workable for a period of 6 to 30 minutes.  The Provisional Specification describes also the use of aqueous dispersions of polyacrylates and polymethacrylates, polymerized esters of allyl alcohol and polymers of other simple unsaturated compounds.

Title: Decoders for 4-channel fm stereophonic composite signals
IPC: H04H20/89
Filed: 1975-02-20
Abstract: 1487496 Quadraphonic FM systems SONY CORP 20 Feb 1975 [25 Feb 1974] 7231/75 Heading H4R In a decoder for quadraphonic FM signals which includes a main channel signal, a 19 kHz pilot signal, two subchannel signals modulated on quadrature related carriers of 38 kHz, a 57 kHz second pilot signal and a third subchannel signal modulated on a carrier of 76 kHz, the decoder includes a detector of the 19 kHz pilot signal and means for deriving a 38 kHz control signal from the detected pilot, and an arrangement which, in response to the detected pilot signal, produces a switching control signal which, applied to a switch fed with the composite signal, causes detection of the 57 kHz second pilot signal which indicates presence of a quadraphonic signal. As described an FM broadcast signal is received in a conventional manner and the composite demodulated signal S(t) is fed to a phase locked loop oscillator arrangement 20 so that oscillator 21 generates a phase locked signal of 152 kHz which, via dividers 22, 23, and 24, generates signals of 76, 38 and 19 kHz respectively. The 38 kHz signal is fed to switching stage 5 to derive, from the composite signal S(t), the conventional left and right channel signals S L  and S R  which are fed to respective switches 6 and 7 controlled by the 76 kHz signal to derive the front and back signals L F , L B , R F , and R B  In addition the 38 kHz signal S38 and 19 kHz signal S19 are fed to an "AND" gate 35 to derive a switching control signal S D . The composite signal S(t), after appropriate phase shift in network 33 is applied to switch 34 controlled by the signal S D  and, if the 57 kHz pilot signal is present in the composite signal, D.C. voltage E DC  is developed which after smoothing and amplification is used to light a lamp 38, indicating a quadraphonic transmission, and enable a switch 27, feeding the 76 kHz signal to the back-front demodulator switches 6, 7.

Title: Improvements in hydraulic brakes
IPC: F16D51/30
Filed: 1933-03-10
Abstract: 411,616. Brakes. HYDRAULIC BRAKE CO., 84, West Hancock Avenue, Detroit, Michigan, U.S.A. March 10, 1933, No. 7306. Convention date, March 17, 1932. [Class 103 (i).] A brake comprises a pair of shoes adapted to be applied to the drum by two hydraulic cylinders, the arrangement being such that the frictional drag on the shoes by the drum acts to augment the pressure on both shoes when the drum is rotating in one or in either direction. In Fig. 1, a pair of pistons in a cylinder 8 engage respectively one end of each of the shoes 11, 12 and the piston of a second cylinder 45 engages the other end of shoe 12. Slotted ends of the shoes engage anchor pins 27, 39 and the other ends are shouldered to abut anchor pins 42, 49. Retractile springs 50, 51 extend between the shoes and additional springs 28, 40 are connected to one end of each shoe. Pressure liquid is supplied to both cylinders to apply the brake. If the drum is rotating in the direction of the arrow the shoes pivot about the pins 27, 39 respectively, the upper end of the shoe 12 being prevented from leaving the pin 39 by the resistance of the two springs 40, 50. The frictional force on both shoes thus acts to increase the pressure on the shoes. If the drum is rotating in the opposite direction, the shoe 12 pivots about the pin 42 so that the friction still acts to increase the pressure on this shoe, but the shoe 11 pivots as before about the pin 27 so that this shoe is much less effective. In a modification, the cylinder 45, is replaced by one having a pair of pistons engaging respectively the lower ends of the shoes so that the pressure on both shoes is increased by frictional action in both directions of drum rotation. The anchor pins are adjustable and for this purpose each pin, for example 27, carries an eccentric 31 that engages the edges of a vertical slot in a plate 32 secured to the anchor plate 5 and passes through a horizontal slot in the plates so that by loosening the nut 36 and turning the pin it is moved towards or away from the drum.

Abstract: 555,238. Printing on cables. BRITISH INSULATED CABLES, Ltd., HARGREAVES, E. G., and DUNKERLEY, H. J., [Representatives of HARGREAVES, E. S.], and STEWARD, H. M. June 6, 1942, No. 7733. [Class 100 (ii)] In an apparatus for marking the surface of an electric cable or similar article, the cable is drawn through hollow trunnions 4, Fig. 1, of a casing 1 in which the marking roller 19 is mounted, and as the cable is advanced the marking roller which is set askew is rotated by driving the trunnions 4 from a motor which may also drive the cable winding mechanism. The cable is thus printed with a helical or like design. The roller 19 co-operates with an impression roller 9 mounted in a bracket 6, and the roller 19 is mounted in a bracket 18 in which is also mounted an inking-roller 29. The brackets 6, 18 are mounted on bolts 7 the axis of which is radial to the cable, and the brackets can be rotated about the axes of the bolts so as to be set at the required angle, and the brackets are then secured in place by nuts 8. The angle depends upon the relative speed of rotation of the casing 1 and the winding- drum. The rollers 9, 19, 29, are each mounted in a pivoted bell-crank lever (11, 21, 31), and are adjustable by nuts which adjust washers 14, 24, 34, having knife-edges which engage recesses in the bell-crank levers and move the brackets against the action of springs which move the rollers apart when the nuts are unscrewed. A casing 1 may be fitted with more than one set of printing-rollers, or a number of casings 1 may be arranged in tandem fashion. and as shown in Fig. 5 a single cable may be printed in succession by rollers arranged in casings 1 which are driven in opposite directions. The printing or marking surfaces are preferably formed of rubber, and have raised designs, and the inking rollers are formed as reservoirs having a small hole leading to a circumferential felt pad.
