Title: Improvements in vehicle braking systems
IPC: B60T8/18
Filed: 1961-07-04
Abstract: 929,598. Fluid pressure brakes. WESTING- HOUSE BREMSEN-G.m.b.H. July 4, 1961 [July 6, 1960], No. 24118/61. Class 103 (1). [Also in Group XXXII] A vehicle air braking system is provided with an hydraulic suspension by means of which the braking effort is controlled in dependence upon the load of the vehicle, the arrangement being such that the hydraulic suspension only comes into operation when the brakes are applied. As shown in Fig. 1, if braking is  initiated by reduction of pressure in the main air pipe 1, control valve 2 admits air from the auxiliary reservoir 3 to the brake cylinder 14 by way of pipes 4, 24, port 23 and pipe 13. This air also acts on the coaxial pistons 6, 9 which are joined and overlaid by an annular diaphragm 12; they move downward until the outer, annular piston 6 is arrested by the shoulder 8. The piston 9, through push-rod 25, rocking beam 26 and push-rod 27a acts on the hydraulic piston 27 which closes the port 31a leading to the oil reservoir 31 and forces oil into the pipe system 30 so that the pistons 35 are raised from the stops 36 and the load on the vehicle determines the oil pressure in the system. As the piston 9 continues to move downward diaphragm 12 lifts from its outer edge in such a way that the effective diameter of the diaphragm (and hence of the piston 9) is continuously reduced as a function of the piston stroke. The pressure of the air supply to the brake cylinder will continue to increase, and will not be interrupted until valve 22, through motion of the piston 9, lies on valve seat 21, the position of which is determined by action of. the brake cylinder air pressure also on the head of piston 17 against opposition of the spring 18; in these circumstances, the brake cylinder pressure acting upon the effective piston face of the diaphragm 12 counterbalances the oil pressure acting on piston 27. A heavier brake application will move both the valve seat 21 and the piston 9 downwards, but as the effective area of the piston 9 is reduced by lifting of the diaphragm 12, equilibrium will be restored without change of oil pressure but at a different position of the valve 22 and piston 9. Each position of the piston 9 corresponds to a certain degree of brake application so that an increase of load and consequent increase of oil pressure calls, in any given position of the valve seat 21, for a corresponding increase in braking air pressure to seat the valve 22. On release of the brake, decreased pressure in pipe 4 causes valve seat 21 to be moved upward by spring 18, lifting valve 22 and venting the system to atmosphere through tube 10 and passage 11 until equilibrium is again achieved. In the event of failure of the hydraulic system, the oil pressure is replaced by the pressure of spring 33 acting on piston 27 through piston 32. Two modified arrangements of the loadsensing piston 35 are illustrated in Figs. 3 and 4 (not shown). The hydraulic force on lever 26 may be replaced by a spring.

Title: Improvements in drying apparatus
IPC: F26B17/20
Filed: 1920-08-19
Abstract: 160,717. Eberts, L. Aug. 19, 1920. Agitators other than conveyers. - D r y i n g - apparatus comprises a casing containing a fluidheated rotary drum which is provided with radial heating tubes, the tubes being arranged in closely spaced circular series from end to end of the drum. As shown, the drum e, Fig. 1, is mounted upon hollow shafts i, k and has radial tubes f which communicate with longitudinal tubes g contained within the casing a. Steam or air passes through the shaft k into the drum and thence through the radial and the longitudinal tubes into a common spiral tube h which discharges through the shaft i into a steamtrap. The material passes through a conveyer b into the space between the drums, and is agitated therein by blades c carried upon arms m secured to the shafts. The radial tubes are of wedgeshaped cross-section, and are secured to the drum so that the thin ends of the wedges are directed towards the outlet d for the material. Additional radial tubes having closed and flattened ends may be used for agitating the material in place of the blades c. In a modification, all the radial tubes f, Fig. 5, are closed and flattened at their outer ends while their inner ends project into the drum. In this case, the steam passes through the shaft at one end into the drum and thence through a bent discharge pipe h at the other end of the drum. In another arrangement, the radial tubes are arched, and have both arms of the arches projecting into the drum.

Title: Improvements in apparatus for measuring the differences between diameters of a cross section of a piece, and in particular of a piece that is being machined
Filed: 1953-09-01
Abstract: 745,577. Gauging departure from standard form. SOC. D'APPLICATIONS ET DE CONSTRUCTIONS POUR MATERIEL AUTOMOBILE S.A.C.M.A. Sept. 1, 1953 [Dec. 6, 1952], No. 24183/53. Class 106 (2). [Also in Group XXIII] An apparatus for determining the amplitude of relative reciprocating movements of two feelers movable with respect to each other and in contact with a rotating piece at points located substantially along the same diameter thereof, is characterized in that a circular member, interposed between two parts respectively connected with said feelers, is mounted to roll with respect to two surfaces belonging to said parts respectively only as far as a predetermined position with respect to at least one of said surfaces owing to the provision of abutment means for said member carried by the part to which said last-mentioned surface belongs, the amplitude of the reciprocating movements of said member from said position with respect to the part carrying said abutment means being indicated by a measuring device interposed between said two parts. The apparatus described includes two measuring devices, which may be mechanical, electrical or pneumatic, having plungers 9, 20, Figs. 1, 2, the first device indicating continuously the length of the actual diameter of a workpiece A being gauged between contacts 3, 6, contact 3 being fixed to a frame 2 which is moved to keep contact 3 in contact with the work and which supports, by two spring strips 14, a member 34 which carries the contact 6, and the second device indicating the difference between the length of the actual diameter being gauged and the length of the smallest diameter that has previously been gauged, i.e. the second measuring device indicates lack of roundness and for a truly circular body it will continuously indicate zero. Movement of the member 34 with respect to the frame 2 is communicated to the plunger 20 of the second measuring device via a ball 16 which is in frictional contact with a groove in a member 26 and with a spring-loaded member 31. Upward movement of the member 34 causes the ball 16 to roll upwards against the small pressure of a strip 22 to depress the plunger 20 and downward movement causes the ball to roll downwards until it strikes an abutment 25 when, on further downward movement, the member 31 commences sliding on the ball. In operation the device has to be initially set so that the ball 16 is in contact with the abutment 25 when the contacts 3, 6 are in contact with the work, which is done by manually raising the contact 6 sufficiently far to cause the strip 22 to come into contact with a second fixed abutment 28.

Filed: 1954-08-20
Abstract: 777,850. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 20, 1954 [Aug. 25, 1953], No. 24273/54. Class 38 (2). [Also in Group XXXIX] A bistable magnetic device comprises two similar series connected coils 2, 3 wound in opposite senses on a single core 1 of magnetic material with a rectangular hysteresis loop. The core is shown eight times in Fig. 3. The core is triggered from one remanent state to the opposite remanent state by a positive pulse in the grid of tube 10 in the anode circuit of which the coils are connected. The speed of operation is increased by using transistors in regenerative circuits. Eight coils 2 to 9, Fig. 3, are wound on the single core, coils 4 and 6 being connected in opposite senses to the bases of transistors 12, 13. If coil 2 is the operative coil, coil 4 responds by making the base of transistor 12 negative. The increase of current passed by the transistor through coil 5 aids coil 2 and provides positive feedback, making the transistor base more negative. Transistor 13 and coil 7 operate in the same way if coil 3 is operative. In a modification, the two oppositely wound coils 22, 23 are included in the base circuit of transistors 20, 21, Fig. 4, and are coupled to the anode of tube 17 by condensers.

A method of manufacturing a crystal contact device comprises the steps of fusing a small quantity of germanium on a refractory support, which solidifies to form a globule having a projecting spike, mounting the globule on a metallic support and removing the spiked part of the globule to form the contact surface for at least one small area electrode. The globule 4 may be prepared as described in Specification 635,385, [Group XL (c)], and mounted on the end of a metal stub 5, as shown in Fig. 3. The spiked portion 1 is then ground away to form a flat surface 8 as in Fig. 4, which shows a crystal rectifier unit similar to that described in Specification 616,065, [Group XL (c)]. Reference is also made to the use of the invention in transistor devices such as those described in Specifications 647,935 and 666,916, [both in Group XL (c)]. The invention results in an improved reverse voltage characteristic of the rectifying contact owing to the tendency for the spiked portion of the globule to have a relatively higher concentration of impurities.
