Patent GB-2133482-A (GB)
Title: Seal assembly
Inventor: LITTLE JOHN ARCHIBALD
IPC: F16J15/28
Filed: 1983-12-09
Abstract: A seal assembly 16 is formed by a journal 14 on a shaft 10, which is rotatably mounted in a machine casing 12, and a non-rotary annular seal member 18 which fits about the journal 14 and protrudes from an annular chamber 52 in a housing secured to the casing 12. The housing has two relatively axially slidable parts 20/24 and 32 which are in sealed relationship with one another to close the chamber 52 and which are urged apart by plunger assemblies 40. The seal member 18 has radially-extending plain annular faces 60, 62 which are engaged, under load, by radially-extending plain annular surfaces 64, 66, respectively, on the housing parts. The seal member 18 also has a circumferential groove 53 which interrupts the inner seal surface. Lubricant under pressure flows from the annular chamber 52 in the housing through passages 55 and 54 in the seal member 18 to the groove 53 and then between the inner seal surface and the journal 14. The inner seal surface may be of white metal 58, steel faced with white metal, or leaded bronze and may be provided with a spiral groove to inhibit the movement of lubricant towards the pressurized side of the seal. The seal member 18 may be constructed from two or more parts and be formed with slots and bores to render the member 18 more flexible (Figs. 2, 3). <IMAGE>

Title: Valve assembly for the control of an outlet pressure in dependence upon an inlet pressure
Inventor: BELART JUAN
IPC: B60T11/34
Filed: 1984-07-04
Abstract: A valve assembly for the control of an outlet pressure (PA) in dependence upon an inlet pressure (PE) comprises an inlet chamber (12) and an outlet chamber (19), separated by a pressure- responsively actuatable valve passage (13, 14) which assumes a normally closed position between two set pressure values in the inlet chamber (12). With a view to simplifying the design of such a valve assembly, the present invention proposes that an annular piston (7) with a valve seat (13) formed thereon is guided in a bore (6) of the valve housing (1). The piston is sealed at its outer periphery and is slidable in opposition to a first compression spring (10). Cooperating with the valve seat (13) is a closure member (14) which is displaceable in opposition to a control force of a spring (17) and whose maximum stroke is less than the possible stroke of the annular piston (7). In operation as the inlet pressure increases the outlet pressure remains equal until the valve element (14) seats on the piston (7). The outlet pressure then remains constant until the bias of spring (10) is overcome when the piston (7) and valve move together increasing the output pressure at a faster rate than the input pressure until the stem (21) abuts the housing and opens the valve again at the second set pressure after which the output pressure again equals the input pressure. <IMAGE>

At least two arms 9, (10 Fig 2) are disposed transversely of the supports, are spaced apart lengthwise thereof and at one end thereof are each suitably connected to claw rail 4. At least two rams 19 (20 Fig 2) are carried by support 6, and the output member 17, (18 Fig 2) of each ram is connected to a respective arm 9, (10 Fig 2) at the other end thereof.   <IMAGE>

Patent GB-857624-A (GB)
Abstract: 857,624. Cash registers. OFFICE MACHINERY Ltd. Oct. 5, 1959 [Oct. 17, 1958], No. 33283/58. Class 106 (1). An adding-machine 7 with a total-clearing lever 10 is removably mounted on a casing 5 containing a cash drawer 6 in such a position that on depression of the lever it actuates a mechanism 27, 22 for the release of the cash drawer. This release mechanism, which is preferably adjustable, may also be actuated by a lever 129 provided for this purpose. As the drawer moves outwardly under the action of a transverse coil-spring 23, a bracket 112 actuates a striker 109 for a bell 108. When the drawer is pushed back, it operates a slide 114, 35 carrying a pawl 117 which advances, by one-sixth of a revolution, a take-up spool 20, Fig. 2 (not shown), for a paper strip which passes from a supply spool 83 over a table 88 to the spool 20. Autographic entries may be made through an opening 18 in a window 16. A flat spring 222 engages a hexagon on the spool 20. The feedpawl 117 is normally disengaged from the spool ratchet so that the spool may be advanced manually. The adding machine is partially enclosed by a cover 15 hinged to the rear of the casing. The catch 80 for releasing this cover is accessible only when the drawer is open. A lock 130 locks the drawer and consequently also prevents removal of the adding machine.

Patent GB-2182693-A (GB)
Title: Detecting excessive wear of a rotatable bit
Inventor: DAVIS JR ALBERT P
IPC: E21B12/02
Filed: 1986-09-25
Abstract: In drilling operations, a drilling fluid is pumped down through a drill stem and is discharged through ports (14) in the drill bit and into the annulus between the drill stem and the wellbore. Excessive wear of the bit at a selected location is detected by at least one abradable sensor (74,76) which is linked to a flow restricting device (78) operable for reducing the flow of drilling fluid through at least one port (14). A wire (94) is connected between the sensor(s) (74,76) and the restricting device (78). As the drill bit wears due to abrasion, sensors will abrade until one or the other sensor is activated. Activation of the sensor is transmitted by the wire (94) to render the restricting device (28) operative. The restricting device includes a ball (80) and, when operated, releases the ball into the drilling fluid to seat against a port (14) in the drill bit. In order that operation of the flow restricting device (78) be substantially unaffected by the pressure of the drilling fluid, it is positioned with its working parts (84) exposed to the drilling fluid upstream of the port (14), whereby at most slight differential pressure acts on the exposed working parts. <IMAGE>

Title: Disposable sterile toilet seat cover
Inventor: HANKINSON RICHARD KEITH
IPC: A47K13/16
Filed: 1986-11-11
Abstract: A sterile toilet seat cover is a thin light sheet of material (4) rendered sterile moisture resistant and impervious to micro organisms capable of being packaged into a relatively small volume for carrying on the person. When opened out and placed on a toilet seat it forms a protective barrier between the seat and the user. A central portion (6) is weaked with perforations along three sides (5) so that before, or while, the user is seated a flap section of the cover may be easily pushed out by hand. The opening thus produced allows unimpeded urination and defaecation. The flap of material prevents genital contact with the seat or pedestal. After use the cover can be easily peeled from the seat by its overhanging periphery, which will not have been in contact with the toilet, and disposed of by flushing or placing in an appropriate receptacle. <IMAGE>
