Title: Improvements in or relating to roller bearings
Inventor: KAY SYDNEY
IPC: F16C33/46
Filed: 1960-11-04
Abstract: 961,203. Bearings and lubrication. COOPER ROLLER BEARINGS CO. Ltd. Oct. 16, 1961 [Nov. 4, 1960], No. 37955/60. Heading F2A. A split cage for a roller bearing comprises two identical half portions 10 with roller pockets 11 equally spaced around the cage periphery. The pockets 11 are formed with two sides 12, 13 parallel to the bearing axis and ends 14, 15 perpendicular to the bearing axis. Each of the sides 12, 13 is formed in two parts 16, 17, part 16 being substantially radial to the bearing axis and situated above a mean diameter or pitch circle line of the cage, and part 17 situated below the pitch circle line and inclined towards a central radial plane of the pocket. This wedge-shaped formation of the pocket promotes hydrodynamic lubrication at the contact zone between the cage 10 and individual rollers 18 and affords the inward retention of the rollers in the cage. Outward retention of the rollers may be provided by peening over the edges of the pockets on the outside diameter of the cage. Grease pockets 20 are formed in the outer surface of the cage 10, between adjacent roller pockets, in pairs axially and extend inwardly from the outer surface of the cage to the pitch circle diameter. The pockets also provide the means of lightening the cage. The spaces between the end roller pockets adjacent the split are not provided with grease pockets but the pocket edges are recessed at 22 to receive a spring-jointing clip to fasten the two halves 10 together.

Abstract: 1487677 Demand regulator for breathing apparatus R A CHRISTIANSON 19 Sept 1975 [23 Sept 1974 30 June 1975] 38545/75 Heading A5T [Also in Division F2] A demand regulator for breathing apparatus consists of a diaphragm 9 which senses a pressure drop during inhalation and is linked by its shaft 14 and an arm 13 with a rod 20 having a central rectangular cross-section part 12, movement of the diaphragm causing the rod to rotate about its axis and also slide along slots 21 in a cylindrical extension of a valve housing 18, such that a ball 15  moved along housing bore 17 opens the valve, the rate of valve opening increasing the greater is the movement of the diaphragm. The housing extension is closed by a member 16 having a hemispherical surface facing the ball and against which the rod contacts. The valve is biased closed by a spring 47 and in the closed condition the member 16 is adjusted to cause contact between itself, the rod, the ball and valve poppet 19. An O-ring 46 engages an edge 45 of the valve housing and seals communication between an inlet 27 and outlet 32. The diaphragm seats against an annular ring 35 to prevent outward movement and during exhalation gas exits via the edge 9a of the diaphragm and out of apertures 41.

Abstract: 1506987 Valves CATERPILLAR TRACTOR CO 17 Sept 1976 [5 Feb 1976] 38576/76 Heading F2V A valve comprises a valve body 24 having a bore 42 intersected by two inlet ports 30, 32, a work port 38 and an exhaust port 34, together with two coacting valve spools 50, 52 which slide within the bore; the spool 50 blocks the inlet 32 from the exhaust 34 when the spool 52 connects the inlet 30 to the work port 38, and vice versa. On actuation of a manual control, the spool 50 moves against the action of a spring 58 to close the ports 32, 34. The spool 50 subsequently contacts the spool 52 and urges it against the action of a further stronger spring 56 until grooves 54 in the spool 52 connect the ports 30, 38. On reverse actuation of the manual control the spring 56 moves the spools, blocking the inlet 30 and then the spring 58 moves the spool 50 to open the inlet 32. In this position of  the spools the grooves 54 connect the work port 38 to the exhaust 34.

Abstract: 1,246,487. Depositing food paste or batter. D. AYRES JONES & CO. Ltd. 18 Aug., 1969 [19 Aug., 1968], No. 39502/68. Heading A2A. [Also in Division B8] An extruding apparatus dispenses batter or other viscous material through a discharge nozzle having an elongated slot, in an element 11 into a container supported on a powered conveyor 10. The container may be a pastry or other bakery product &c. Even distribution of the material is ensured by delaying the movement of the container until after delivery has commenced. The conveyer and metering pumps are driven in the forward direction by motors 12 and 13 respectively through variable transmission means 15, 31. Electronic control means may operate to stop and start the conveyer through a clutch 16 and a brake 17 or the conveyer may operate continuously and the container be held and released by a solenoid controlled lever (72), Fig. 5 (not shown). Delivery of material is started by engaging the clutch 32 which causes the shaft 33 to rotate through the free-wheel device 34 operating a dispensing pump (not shown). After a preset delivery time the clutch 32 is disengaged and the clutch 21 engaged, thereby reversing the rotation of the shaft 33 and consequently of the pump, ensuring a sharp cut off the delivery. Rotation in this sense engages the free wheel device 34 which through engagement of a dog-clutch 36, 37 causes the conveyer to be lowered, breaking strands of material which may join the material in the container to the slot. The cycle may then be repeated.

Abstract: 1,087,119. Coating apparatus. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 17, 1965 [Oct. 22, 1964], No. 39737/65. Heading B2L. In applying liquid media to a surface, the surface is passed over a container 1 containing the medium 2 in which there is immersed a partly or wholly porous body 3 through which gas under pressure is passed so as to foam the liquid medium, and guide plates 5 and 6 are arranged around the porous body 3 for ensuring that the foam wave developed in the medium is moved in a direction opposite to the direction of movement A of the surface to be wetted. The plates 5 and 6 extend the full length of body 3 and the plate 6 facing the incoming surfaces to be wetted is set lower in the medium that the plate 5 so that a foam wave is produced. The height of the foam wave can be regulated by varying the gas pressure supplied and the size of the foam bubbles may be adjusted by the depth of immersion of the body 3. As soon as the bubbles in the foam meet upon the surface to be wetted they burst and spread into a thin film on the surface.
