Title: Jacking system
IPC: A61G7/005
Filed: 1964-10-06
Abstract: 1,084,020. Beds. COX OF WATFORD Ltd. and C. TOON. June 11, 1965 [Oct. 6, 1964], No. 40774/64. Heading A4J. [Also in Division B8] A hospital bed includes a jacking system which comprises a chassis frame 1 mounted on castors 2. A mattress 26 is carried on a mattress frame 25 mounted on a subframe 3. The sub-frame 3 is mounted on the frame 1 by two connecting frames 4 with cross members 5, Fig. 3 (not shown), mounted between depending portions 3a so as to be rotatable about horizontal axes 6. Each frame 4 has a short lever extension 7 engaged with a a screw and nut mechanism, Fig. 4, in a housing 8. Rotation of a handle 19 on an extensible shaft 18, through opposite handed threads, separates the upper ends of lever extensions 7 to raise the frame 3 by means of long lever extensions 21 pivoted in slots (not shown) in the chassis frame 1. Lifting is assisted by tension springs 37. Lowering is achieved by reversing the rotation of the handle 19 to draw the upper ends of the short lever extensions 7 together. The mattress frame 25 has removable safety rails 2 and is pivotally attached adjacent the head end of the sub-frame 3 so that it can be turned about a horizontal axis, a cross-bar 34 engaging in any one of recesses 33a in slots 33 in supporting struts 32 to retain the desired inclination.

Abstract: 1445394 Bolts INDUSTRIAL ACOUSTICS CO Inc 30 Aug 1973 [31 Aug 1972] 40858/73 Heading F2H A safety bolt 10 for engagement with an internally threaded member 14 has a pawl 26 housed in a longitudinal slot 28 and pivoted to the bolt at 33 adjacent the leading end of the bolt, the free end 46 of the pawl, which lies within or adjacent to the threaded portion 20 of the bolt shank, being spring-loaded radially outwardly so that when the bolt is screwed into the threaded bore 22 of the member 14, as soon as the free end 46 of the pawl emerges from the exit surface 48 of the member 14 it is extended to latch against the surface 48. A leaf spring 34 acts between the pawl and the bottom of the slot 28. The pawl is retractable to lie wholly within the root diameter of the belt thread, and its extension from the slot is limited by engagement of a shoulder 52 of the pawl with the bottom of the slot. The pivot pin 33 of the pawl is hollow so that it may be sheared to allow release of the pawl and removal of the bolt from the member 14 when a sufficient torque is applied to the bolt. The bolt may have a head at its rear end (not shown) or may have a second screw-threaded rear end portion 18, as shown. A nut 38 can be locked to the bolt by the engagement of the inturned ends of a semicircular locking spring 40 with slots 42 in the nut and bores 44 in the bolt.

Filed: 1972-09-04
Abstract: 1342215 Rotary IC engines AUDI NSU AUTO UNION AG AND WANKEL GmbH 4 Sept 1972 [6 Sept 1971] 40860/72 Heading F1F In a rotary internal combustion engine of the trochoidal type, each side of the piston 9 has a central circular opening 23 through which the piston shaft 6 passes, each opening having therein an annular axial seal 24 for preventing lubricating fluid in cavities 18 in piston 9 leaking out between the piston and end walls to the working chambers. Each annular seal 24 comprises two concentric sealing rings 25, 26 of L-section. The outer ring 25 is sealed with respect to the cylindrical surface of opening 23 by an annular sealing element 30 of C-section. A similar element 31 seals the rings 25, 26 relative to each other. The rings 25, 26 are urged axially outwardly by an annular wavy spring 27 located in an annular groove 32 of a support member 28 connected to piston 9 by screws 29. Groove 32 communicates via notched channels 35 with the lubricating  chambers 18 thus ensuring that the seal 24 is constantly cooled and lubricated. The support member 28 is constituted on one side of piston 9 by an internally toothed gear wheel 11 which engages pinion 12 integral with housing end plate 3. To reduce friction, element 30 can have its outer face coated with PTFE.

Title: System for controlling the flow of byepass liquid from a centrifugal pump
Inventor: MCALPINE THOMAS JAMES
IPC: F04D15/00
Filed: 1958-12-19
Abstract: 893,102. Centrifugal pumps. WEIR Ltd., G. & J. Feb. 11, 1960 [Dec. 19, 1958], No. 40976/58. Class 110 (1). [Also in Group XXIX] A centrifugal pump, fed by a booster pump, discharges liquid through a pipe 29 and through a non-return valve 13 to the point of use, such as a boiler. A pilot valve 5, controlling the flow of liquid from the pipe 29 to a relay 3, is positioned by the non-return valve 13, through a bell-crank lever 24 such that for small flows through the non-return valve, pilot valve 5 is held open. The relay valve 3 is spring-loaded such that this valve will not open until the pressure in the line 29 reaches a predetermined value at which value the relay valve opens and allows flow through a pipe 32 to act on a piston 33 of a by-pass valve 6 to open this valve and by-pass liquid from the pipe 29 through a pipe 38. Thus for small flows through the pipe 29, the by-pass valve cannot open until a predetermined pressure has been reached in the pipe. When the pilot valve 5 closes, liquid trapped between this valve and piston 33 leaks past the piston allowing the bypass valve and relay valve to close. In a modification, the opening of the relay valve allows leakage from the upper face of a by-pass valve, which allows the pressure in the line 38 to open this-by-pass valve. Specification 562,833 is referred to.

Title: Device for automatically pressing plate-shaped workpieces against and removing them from a machining tool
IPC: B24B7/28
Filed: 1963-10-17
Abstract: 979,100. Grinding. P. ERNST. Oct. 17, 1963, No. 41030/63. Heading B3D. [Also in Division B8]  A device for automatically pressing plateshaped workpieces 7, Fig. 1, against, and removing them from, a working tool 12, such as a grinding or polishing roller or a brush, after the leading edge of the workpiece has run under and before the trailing edge thereof has run out from under the working tool, comprises a conveyer belt 1 for carrying the workpiece under the tool, pressure rollers 5, 6 for pressing the workpiece on to the belt, and a rocking element 4 pivotable about a pivot axle 11 arranged underneath the belt and parallel with the tool, said element carrying two rotatable guide rollers 2, 3 mounted one on each of the side of the pivot axle and bearing against the underside of the belt. As the workpiece is moved through the machine in the direction of the arrow 8, the roller 6, which may be spring or weight actuated, presses the workpiece against a table 10 beneath the conveyer. The leading end of the workpiece then acts to press the roller 2 downwardly and passes beneath the working roller 12. The workpiece is not engaged with the roller 12 until its leading end has also engaged the roller 3 which causes the element 4 to move to a horizontal position with the consequent raising of the workpiece into engagement with the working roller. As soon as the trailing end of the workpiece leaves the roller 2, the element 4 rocks in the opposite direction to prevent engagement of the trailing end of the workpiece with the roller 12. The arrangement prevents excessive abrasion and damage of the leading and trailing ends of the workpiece. In another embodiment having a relatively stiff conveyer belt, the rollers 2a, 3a, Fig. 4, are mounted on a plate 14 pivotable about an axle 11a, the plate also having a roller 13 about which the belt is guided.

The other ends of rods 19, 20 are pivotally mounted on the underside of seat body 2. A damping block 36 prevents seat body 2 from hitting frame 1. A seat back 4 is adjustably mounted on a plate 27 provided on seat body 2. Frame 1 may be locked in an adjusted position on a slideway 34 by a lever 35.
