Title: Hydraulic braking device in particular for power vehicles
IPC: B60T11/224
Filed: 1953-10-23
Abstract: 732,955. Hydraulic brakes. TEVES, A., TEVES, H., and TEVES, E. A., [trading as TEVES MASCHINEN-UND ARMATURENFABRIK KOMM.-GES., A.]. Oct. 23, 1953 [Jan. 9, 1953], No. 29379/53. Class 103 (1). In order to increase the braking pressure to the brakes of the front axle of a vehicle, a pressure converter 6 is fitted between a pipe connecting the master cylinder 1 and the pipe leading to the brakes of the front axle. As shown in Fig. 1 a braking pipe 2 leads from the master cylinder 1 to the wheel brake cylinders 3, 4 of the rear wheel brakes and a further pipe 5 to the pressure converter 6 and thence by pipe 7 to the wheel brake cylinders 8, 9 of the front wheel brakes. The braking' pressure produced to the master cylinder 1 is transmitted unchanged to the rear wheel brakes but the pressure transmitted to the front wheel brakes is increased by the pressure converter. As shown in Fig. 2, the pressure converter consists of a low-pressure piston 12, movable in the main low-pressure cylinder 10 of the pressure converter, and a high-pressure piston 13 movable in a smaller, high-pressure cylinder 14. - In a boring in the high-pressure piston is a fluid-tight movable pin 15; one end of which is subjected to the pressure in the high-pressure space 16, the other end acting on a pressure-relieving device in the form of a spring-loaded ball-valve 17. If the space 29 behind the low-pressure piston 12 is supplied with pressure liquid from the master cylinder 1 via pipe 5, the piston moves allowing liquid in the low-pressure space 22 to pass through the longitudinal holes 30 in the highpressure piston into the high-pressure space. When the brake shoes contact the brake drum the pressure in the high-pressure space increases and acts through the pin 15 on the ball-valve 17. Similarly, pressure in the low-pressure space 22 acts on the ball valve 17 through the hole 21. When the ball valve opens, the liquid of the low-pressure space 22 no longer passes into the high-pressure space, but flows through poles 23 and 25 into an equalizing vessel 26. This pressure conversion results in the pressure in the high pressure space, and therefore in pipe 7, varying continually in dependence on the foot pressure. The pressure converter may be combined with the master-cylinder to form one unit.

Title: Improvements in or relating to detergent preparations
Inventor: HARVEY CHARLES EWART
Filed: 1955-10-14
Abstract: Crude sodium fatty-acyl-aminomethane-sulphonates (such as those made by condensing fatty acid amides with sodium formaldehyde bisulphite) are purified by forming them into small discrete particles and washing them with an aqueous liquid at a temperature below that at which appreciable dissolution occurs. The particles may be granules, flakes or threads, the dimensions and conditions of washing being such that they do not coalesce. Best results are obtained with flakes of thickness 0.01-0.05 cm., preferably 0.025-0.04 cm.  The washing water may contain in solution an inorganic electrolyte at a concentration below 10 per cent (preferably below 2 per cent); sodium chloride and hydrochloric acid are suitable.  The temperature should be below 10 DEG  C. and preferably below 5 DEG  C., and may be below 0 DEG  C. when electrolytes are present.  The process is particularly applicable to the products of condensing amides R-CO-NH2 with sodium formaldehyde bisulphite where RCO has 10-18 carbon atoms, especially the amides of palm kernel or coconut oil fatty acids. This condensation is effected in the presence of 1-5 per cent of a mild alkali such as sodium carbonate, the amount of amide being 1-1.5 (preferably 1.2-1.4) mols. per mol. of sodium formaldehyde bisulphite.  A secondary amine may be used in the presence or absence of the mild alkali.  The reactants are heated to 150-210 DEG  C. (preferably 170-190 DEG  C.) in an inert atmosphere. Examples are given of the preparation and purification of sodium (palm oil acyl) aminomethane-sulphonate using aqueous sodium chloride as washing liquid.  According to the Provisional Specification the process is applicable to detergents generally, including fatty acyl taurides and alkylaryl sulphonates.

Filed: 1956-10-02
Abstract: 803,720. Digital electric shaft-positioning systems. COLLINS RADIO CO. Oct. 2, 1956 [Jan. 4, 1956], No. 30016/56. Class 40 (1). A remote signalling system which may be used to position a tuning shaft has means for selecting alternative combinations of energizable circuits. The control switch arms 3-6 are operated so as to change over from the grounded contacts such as 3a to the contacts 3b in accordance with the binary representation of the required position of the remote shaft 19 which may be chosen in the described embodiment from sixteen possible positions. A circuit or circuits through the remote motor 20 are thus closed to drive the controlled shaft 19 to operate the switch arms 15-18 which may be cam-operated switches thereby sequentially closing the motor energizing circuits until coincidence with the desired set position is obtained. If the permutation change switch 1 is operated in a counter-clockwise direction to connect the line 14 through the arm 28 and the contact 29 to ground then the controlled shaft 19 is operated through two positions for each change of position of the control switch since the binary " units " switch 6 of the control switch is connected to the binary " twos " switch 17 on the controlled shaft. A further such rotation of the switch 1 results in the controlled shaft being operated through four positions for each change of position of the control shaft. Similarly, rotation of the switch 1 in a clockwise direction to connect the line 11 to ground results in the controlled shaft operating through one position only in response to operation of the control switch through two positions. As described in more detail (Figs. 2, 3, not shown), relays which operate to control positioning of a controlled shaft as described in Specification 660,939 may be provided.

Abstract: 742,829. Automatic phase-control systems. RADIO CORPORATION OF AMERICA. Oct. 30, 1953 [Nov. 15, 1952], No. 30089/53. Class 38 (4). [Also in Group XL (c)] A phase discriminator comprises a P-N-P (or N-P-N) transistor between the emitter 21 and base 23 of which one oscillation from a source 31 is applied, and between the emitter 21 and collector 25 of which is applied a comparison oscillation from a source 33 through a load resistor connected to output terminals A, A1. The emitter to collector path shown is conductive only during alternate negative half-cycles of the bias of the base 23, and a negative or positive D.C. voltage appears across an integrating circuit connected to the load resistor when the oscillation 33 is in other than phase quadrature relation with the source 31. The oscillations 31, 33 may be other than sinusoidal. The discriminator is insensitive to amplitude modulation, as increasing amplitude decreases the emitter-collector impedance and hence increases the loading of the input. Symmetrical functioning may be obtained by connecting two asymmetric-transistors in reversed parallel relation. Point contact instead of junction transistors may be used. The phase detector of Fig. 1 may be applied to detecting phase deviations between the horizontal pulses from the synchronizing separator of a television receiver and the sloping flyback portions of saw-tooth waves derived from horizontal scanning flyback pulses of the receiver and fed to a shunt capacitive circuit 83 generating the said saw-tooth waves. The D.C. voltage detected may then be applied to a variable reactance member 91 frequency correcting the oscillator 93 controlling the horizontal scan. Specification 742,134, [Group XL (c)], is roferred to.

Abstract: 390,763. Centrifugal - machines. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK REINEVELD, 111, Haagweg, Delft, Holland. Oct. 31, 1932, No. 30573. Convention date, Dec. 17, 1931. [Class 23.] The sieve or wire gauze of a centrifugal strainer is cleaned by raising the pressure in a closed chamber between the drum and the casing, so that any deposit is blown off the inner surface of the drum. The motor 1 drives the drum which consists of outer and inner sieves 2, 3, Fig. 1, and has a scraper 4 which dislodges the solid material. The drum and the casing are provided with sealing ribs forming labyrinth packing 9. A chamber is thus formed round the drum, to which air can be supplied through the pipe 13 to clean the sieves by blowing inwardly therethrough. The sealing ribs may be provided on the front and rear faces of the drum. In the modification shown in Fig. 3, pistons 16 with nozzles 17 rest in cylinders 14. Air supplied through the valve 20 and pipe 15, moves the pistons until the nozzles are close to the drum, and the cleaning operation can proceed. After this is over, springs 19 push the pistons outwards.
