Patent GB-2057337-A (GB)
Title: Contoured molded pulp container with polyester liner
IPC: B65D1/28
Filed: 1980-06-27
Abstract: An inexpensive, disposable, ovenproof container is produced by molding a contoured base 10 in a die 12 with suction ports 14 from an aqueous slurry of non-browning, substantially 100% bleached kraft wood pulp, and drying under pressure using heated mating dies. A liner is formed by bonding to the base 10 a 0.5-2.0 mil thick film 16 of thermoformable, substantially amorphous, substantially unoriented polyethylene terephthalate having an M.W. believed to be above 15,000. The film 16 is bonded to the base 10 by pre-heating the base, rapidly preheating the film 16 using a plate 18, then quickly pressing the film 16 into contact with the base 10 at 300-375 DEG F using a vacuum of about 50.8mm Hg applied through the base 10 for no longer than about 1 second, and finally cooling to prevent shrink separation of the liner from the base. <IMAGE>

Title: Device for food service and clean-up
IPC: B65D43/18
Filed: 1980-07-30
Abstract: A device is provided in which food, such as hors d'oeuvres and the like are carried on a plate (13) which is rotatably attached atop a small bowl (11), e.g. with a snap stud fitting 23. When leftovers and/or trash are accumulated on the plate, the plate may be rotated aside, in the plane of the plate itself, to uncover the bowl, allowing the trash to be swept into the bowl. The plate is then rotated back into position atop the bowl, in preparation for further consumption of hors d'oeuvres by the user. A number of devices may be "stacked" one on another, provided that the plate of each device is rotated away from the attached bowl. This "stacking" greatly facilitates packaging, shipping and marketing of the devices. <IMAGE>

Title: Jack for supporting modular floor
IPC: E04F15/024
Filed: 1980-07-31
Abstract: A Jack has a base (11), a head (14), and body rising from the base to support the head. The body (13) is a hollow tube carrying a captive nut (17) which co-operates with a stud (12) rising from the base (11), so that the body is supported in height-adjustable manner on the stud. Releaseable mechanical means of adjustment take the form of studs (22) projecting from the undersurface of the base (11). The projecting ends of the studs (22) are hardened and ground conical. Rotation of the studs (22), one of which projects from each corner of the square base (11) brings the jacking surface of the jack head (14) into a desired attitude relative to a surface on which, in use, the jack base (11) stands. Thereafter, the conical ends of the studs (22) show virtually no tendency to rotate, thus tending to maintain the jacking surface in the desired attitude until the studs (22) are positively released. <IMAGE>

Title: Hydraulic Two-circuit Power Braking System
IPC: B60T13/14
Filed: 1980-08-14
Abstract: The present specification relates to a hydraulic two-circuit power braking system for use in motor vehicles, the system being of the kind having two brake valves which, by way of a two arm lever and according to the actuation of a pedal, admit the pressure fluid of a pressure-producing device to the brake cylinders. In the present invention the pressure fluid supply of the two brake valves (2,3) is protected by non-return valves (49,50), the two brake valves (2,3) being actuable by way of push rods (7,8) which are in the form of outlet valve control slides and which are surrounded by annular pistons (11,12) the annular pistons (11,12) abutting against a housing stop (23,24) when the pressure fluid supply is intact and, in the event of failure, the annular pistons (11,12) coming into engagement with the two-arm lever and being usable as auxiliary master cylinder pistons to produce braking pressure. Thus, in the event of pressure fluid supply failure, brake pressure can still be applied though only by virtue of the pedal (4). <IMAGE>

Title: Paging receivers
IPC: H04W88/02
Filed: 1980-09-25
Abstract: A paging receiver comprises an information setter (15) which stores information that designates individually assigned call numbers and is constituted by a memory device. In addition to the call numbers, the memory device also stores receiver performance information including information relating to selection of informing devices (25, 28, 30, 33) which report to a user. A decoder (14), preferably in the form of a microprocessor, stores the information from the information setter (15) in a memory device (14d) contained in the decoder and then effects control of a receiving operation as well as selective reception of a call number alerting the user through devices (25, 28, 30, 33) or storing a received message for future recall. It is thus possible to decrease the number of terminals of a decoder fabricated with integrated circuits, thus reducing the size and increasing the reliability of the receiver. <IMAGE>

Title: Blood pressure measuring equipment
IPC: A61B5/022
Filed: 1981-02-12
Abstract: Blood pressure measuring equipment comprises a sleeve (1) with an inflatable air chamber (31) and a microphone (33), and an appliance (3) for measurement and indication of systolic and diastolic blood blood pressure. Sound signals delivered by the microphone (33) during measurement are fed through filter means (51) to a discriminator (53) which generates a pulse for each Korotkoff sound. Diastolic pressure is measured on the last pulse that is formed with the air chamber decreasing. The transfer function of the filter means (51) can be changed in such a manner that diastolic pressure is measured selectably at the so-called fourth or fifth Korotkoff sound eg. by using a transfer function characterised by an enhanced lower frequency transmission to detect the softer fifth Korotkoff sound. In this manner, the blood pressure measurement can be adapted to the individual characteristics of a patient. <IMAGE>

Title: Pipe swivel joint
Inventor: KRAMER JAMES HARMON
IPC: F16L27/08
Filed: 1982-12-16
Abstract: A swivel joint (Figure 2) for use in interconnecting a pair of axially spaced risers in an off-shore multi-line riser system for conveying petroleum from a collection point on the ocean floor to a floating buoy for delivery to tankers, comprises telescoped tubular members (58, 59) (Figure 3) between which is arranged an elastomeric sealing ring (78) bonded to the inner member (58) and sliding in a PTFE liner (79) in the outer member (59).
