Title: Improvements in or relating to circuits for the measurement or control of direct voltage
IPC: G01R19/00
Filed: 1946-07-24
Abstract: 616,564. Automatic control systems. PHILIPS LAMPS, Ltd. July 24, 1946, No. 22008. Convention date, Oct. 3, 1942. [Class 38 (iv)] [Also in Group XXXVI] In a D.C. voltage controlling or measuring system, variations in voltage across a load are amplified by a valve and the measuring or controlling device is connected between the high potential side of the valve load and earth. As shown, Fig. 4, a D.C. three-wire system comprises generators 16a, 16b and positive, negative and earthed neutral conductors 13, 14, 15, the voltages between which are measured at a remote point by meter 3, of which terminal 11 is earthed. Resistors 17, 18 are in series between lines 13, 14 and are respectively provided with tapping points 19, 20 which both occupy the same relative positions on resistors 17, 18. The voltage at 19, 20 is amplified by the valve 6 and its associated load resistor 10, the voltage across which is measured by meter 3. The meter registers simultaneously the voltages developed between points 2, 20 and across resistor 10, and as the former is negligible in comparison with the latter, due to the gain of the valve 6, the meter readings indicate the voltage between lines 13, 14. In a simple embodiment, not shown, the D.C. voltage developed across a resistor, which is earthed at a point on its length, is applied at the grid and cathode of a valve amplifier so that an amplified voltage is produced across the valve anode-load resistor. One terminal of a meter, of which a second terminal is earthed, is connected to the anode end of the load resistor. In a voltage control device, Fig. 7, the load 32 is supplied from the D.C. machine 31 and the load voltage is detected and amplified as in Fig. 4, by the valve 6 and resistors 17, 18. The amplified voltage variations appearing across resistor 10 are applied between the grid and cathode of valve 33, to counteract the effect of voltage changes at the machine 31 and the voltage across load 32 is maintained constant. A second generator may be included in the circuit between the load and valve 33 when it is necessary to earth point 36.

Title: Improvements in hydraulic transmission mechanism
IPC: B60T11/16
Filed: 1939-08-04
Abstract: 533,224. Hydraulic transmission systems ; hydraulic brakes. PRATT, J. H., MANLEY, G. E., and GIRLING, A. H. G. Aug. 4, 1939, No. 22620. [Class 69 (ii)] [Also in Group XXXIV.] In a hydraulic transmission system the master piston 7 of a hydraulic brake or other device is maintained by a spring 17 in its inactive position, and in this position the liquid from a reservoir has access to the cylinder via a pipe 10 and a groove 6c, Fig. 2, in the cylinder, and in front of the cylinder is a stationary packing ring 11 into contact with which the piston 7 is brought when it is advanced to generate pressure. The packing ring is pressed by a spring-member 13 to cause one edge of the ring to engage a fixed ring 12 secured to the cylinder, and the lip 11d of the ring forms an aperture of slightly smaller diameter than the piston which is forced through the aperture and is then sealed by the liquid pressure which forces the lip against the piston. The hydraulic pressure is transmitted to the brake by a pipe connected to an aperture 15. On the return motion of the piston, the lip 11d moves away from the piston and allows the equalization of the pressures in the reservoir pipe 10 and the brake system. In modifications, the groove 6c may be replaced by two grooves (external and internal) in the end of the cylinder connected by port holes, or as in Fig. 4 by an external groove 6h connected by ports 6g to a groove 11c in the ring 11 which is also formed with radial grooves 11e. In a further modification, the piston 7 is formed with a head of larger diameter than the main body, and a wide groove is formed in the enlarged head which co-operates with narrower grooves in the cylinder. The cylinder may be formed of two screwed parts.

Abstract: 1,185,328. Beds. H. KETTLER [trading as HEINZ KETTLER METALLWARENFABRIK]. 16 May, 1967 [16 May, 1966], No. 22626/67. Heading A4J. [Also in Division E2. In a hinge joint between foldable bed frame sections 3 and 41, having a collapsible leg frame 32, a disc 9 is displaceable, alternatively to lock either section 3 or section 41, with respect to a pair of mounting plates 1. In the folded condition, section 41 and frame 32 lie on opposite sides of section 3 and the section 41 is locked to plates 1 by the disc 9 engaging recess 14. To erect the bed, frame 32 is first swung out to the position shown about pivot 22, connecting it to member 2. Section 41 together with plates 1 are initially moved from a position, in which pivots 10 and 7, carried together with pivot 18 of pawl 17 on the plates 1, overlie pivot 4. During this movement, the members 1 and 41 turn about pivot 4 and disc 9 rides on the periphery 11 of member 2. When section 41 is perpendicular to section 3, the movement of the plates 1 is terminated in the position shown, in which abutment edges 23 secure the leg frame 32 in the erected position and disc 9 is brought opposite recess 13. No further movement of section 41 is possible without releasing pawl 17. This is done by raising lever 30, to relieve the pressure of spring 27, acting downwardly on the tail 17a, by lifting slide 25. Compression spring 28 can then raise slide 26 and turn the pawl 17 about its pivot 18. Rod 29b ensures that a similar arrangement on the opposite side of the bed is operated simultaneously. Release from pawl 17 enables section 41 to be rotated about pivot 7 and the initial rotation shifts disc 9, from one end of slot 8 to the other and into engagement with the recess 13, to lock the section 3 with respect to the plates 1. On releasing lever 30, the pawl 17 is reengaged with teeth 16, at the selected inclination of frame 41, by the action of compression spring 27 and slide 25. The hinge joint is encased and sealed with mating plastics half shells 37, (37a), 38, 38a and 39.

Abstract: 430,064. Wringers. TENNANT, W. J., 111, Hatton Garden, London.-(Williams, C. B.; Kinsman, Ohio, U.S.A.) Aug. 3, 1934, No. 22705. [Class 138 (ii)] In a wringer a feed roller is so mounted that it may be moved into engagement with either pressure roller and the latter are so arranged that goods may be fed to the machine from either side without altering the direction of rotation of the rollers. In the form shown in Fig. 4 the bearings of the shaft 30 of one of the pressure rollers 40 are carried by a stationary cylindrical casing 20 at each end of the machine and those of the shaft 42 of the other pressure roller 41 are slidably mounted in other cylinders 36 concentric with the cylinders 20 and rotatable therein. The cylinders 36 are locked to the cylinders 20 in any adjusted position by a nut 140 and by the handle 53 of the pressure screw 51, peripheral slots being provided in the cylinders 20. The feed roller 55 is carried by arms 58 pivoted at 59 to brackets 60 resiliently suspended within the cylinders 36, and a stripper bar 76 having two concave surfaces is secured between the brackets 60. The arms 58 are locked in one or other of two positions by the engagement of a plunger operable from outside the casing 20 in a hole 70 or 71 in the bracket 60. When the plunger engages the hole 71 the feed roller engages the pressure roller 41, the goods are fed in at the left-hand side, Fig. 3, stripped from the roller 55 by the bar 76 and directed between the rollers 40, 41 as shown by the arrows. When the roller 55 is swung to engage the roller 40 as in Fig. 2, the plunger now engaging the hole 70, the direction of feed and delivery is reversed as shown. To facilitate the feeding of the goods the cylinders 36 are rotated within the cylinders 20 so that the pressure rollers no longer remain in the same horizontal plane as in Fig. 4 but assume an inclined plane as in Figs. 2 and 3 according to the direction of feed. The rotation of the cylinders automatically rocks the drip plate 150 through pins 153, 154 and cams 157. In the form shown in Fig. 13 the pressure rollers 101, 102 remain in the same horizontal plane whatever the direction of feed, and the feed roller 110 is journalled on yielding plungers 113 which are slidably mounted in pivoted sleeves 114. The feed roller shaft 110a engages one of the hooks 120, 135 of a rocking plate 121 carrying the stripper bar 126 according to the position of the sleeve 114, which is controlled by the operator, the plate 121 rocking about one of the pins 122, 136 and the roller 110 engaging one of the rollers 101, 102 alternatively. Spring-pressed plungers 130 hold the sleeves 114 in their adjusted position.
