Patent GB-2161923-A (GB)
Title: Catalytic camping stove
Inventor: BRUNO CLAUDIO
IPC: F24C3/14
Filed: 1985-07-02
Abstract: A catalytic stove (10) has a mixing chamber (18) having one end adapted to receive a fuel can (12) and an opposite end provided with a diffuser (28). A plate (30) provided with a grid extends across the exit end of the diffuser (28). A catalytic surface is coated on the exit portion of the plate (30). As the fuel, eg propane, butane, passes through the mixing chamber 18, it entrains air. The fuel/air mixture is then ignited at the top of the chamber 18. After several seconds, the catalyst is heated and the flame is extinguished by turning off the gas flow. The gas flow is re- established and catalytic combustion takes place at surface of plate 30. Food may then be cooked by placing pan on supports 36. <IMAGE>

Title: Semiconductor chip carrier system
Inventor: GRABBE DIMITRY G
IPC: H01L23/057
Filed: 1987-09-09
Abstract: A thermal stress resistant chip carrier includes a housing (11), semiconductor chips (13) mounted on a substrate (12), and a plurality of electrical terminals (36) which extend through one or more walls (21, 22, 23, 24) of the housing (11).

Patent GB-2215557-A (GB)
Title: Interface unit
Inventor: PATEL JITENDRA JASHBHAI
IPC: H04L12/24
Filed: 1988-02-27
Abstract: The interface unit is a message switch used in a telecommunication system between control and monitoring means and the system proper. It includes a set of USART's, one of which is a master and is connected to a link from the control and monitoring means, while the others are slaves which give access via output ports to various portions of the system. A message from the control and monitoring means passes via memory to a processor which determines the action needed, and emits a message via the appropriate slave USART to the appropriate part of the system. A message from the system, either in response to a message from the interface or generated in the system, is received via the appropriate port and is passed in a reverse manner to that just described to control and monitoring means. Messages generated in the system are usually alarms. <IMAGE>

IPC: E02D35/00
Filed: 1988-04-27
Abstract: In the underpinning of a wall (4), a shallow pit (6) is dug alongside the wall, from which a cavity (8) is dug, the cavity (8) extending generally as a rectangle for a depth of typically three-quarters of brickwork. From within the cavity (8) brickwork is removed to provide a cavity (11) in the wall. A vertical hole (12) is then augered from the base of the cavity (8), typically to a depth of 3.0 metres. A prefabricated steel cage (16) is inserted into the augered hole, and is intermeshed with a prefabricated steel reinforcement cage (20) which is located within the cavity (8) and which extends into the cavity (11) in the wall. Concrete is then admitted to the bore, and to fill the cavities (8 and 11), to provide a supporting member to provide load bearing support for the wall. <IMAGE>

Title: Small animal trap
Inventor: WHITE BRIAN
IPC: A01M23/30
Filed: 1989-03-16
Abstract: The trap comprises a housing 1 for placement in a path frequently taken by rats or other small animal pests, and has openings at opposite ends for entry of an animal from either direction. A hammer bar 25 is coupled to toggle bars 34, 36 and when the trap is primed the toggle bars are held by engagement of a pin 41 in a notch 45 in the edge of a catch plate 42. The catch plate is in turn held by a pin 22 which is secured to a trigger plate comprised in the floor of the housing. The hammer bar 25 is blassed downwards by a spring 29 so that when the weight of an animal on the trigger plate releases the catch plate 42 the hammer bar rapidly moves downwards to deliver a potentially fatal blow to the animal. <IMAGE>

Title: Electromagnetic contactor
Inventor: ICHIMURA YASUO
IPC: H01H51/22
Filed: 1989-09-07
Abstract: An electromagnetic contactor (10) comprises an electromagnetic block (11) which includes an armature (32) having a plunger (33) and a pole-contacting member (34), a coil bobbin in which the plunger (33) is axially displaceable, an inner yoke (38) disposed to oppose a peripheral portion of the coil and the pole-contacting member (34) of the armature, an outer yoke (43) disposed to oppose the inner yoke for restricting displacement of the pole-contacting member (34) of the armature, and a permanent magnet (42) interposed between the inner and outer yokes. A contact block having stationary contacts and movable contacts is coupled to the armature (32) by a coupling member (49) which is effective to make and break contact between the movable and stationary contacts. The relative positions of the electromagnetic block (11) and the contact block are adjustable and the arrangement is such that any leak of magnetic flux due to coil excitation and that of the permanent magnet disposed between the yokes can be confined to a minimum. <IMAGE>

Title: Multi-standard digital colour field detector
Inventor: BISHOP THOMAS S
IPC: H04N17/02
Filed: 1989-09-11
Abstract: A colour field detector includes an analogue section 12 which receives a video signal impact 16 and provides signals to drive a digital section 14. A timing generator 40 receives a free-running reference clock 64 at 8 fsc and supplies an internal subcarrier reference signal INT Fsc locked to the leading edge of horizontal sync, and sets of timing pulses T0-T4. A burst edge sampler 42 indicates alignment of the edges of INT Fsc with the burst crossings as a phase shifter 32 is adjusted during setting up. A burst phase comparator samples the colour burst polarity at T1 and T2 which should lie within the same half cycle (more than one half cycle may be sampled) near the centre of a burst of a selected line in each odd field and generates signals indicative of polarity or if an error exists (T1, T2 samples of opposite polarity). A state machine 46 identifies the field sequence from the pattern of polarities from a succession of sampled bursts (or indicates error if the pattern is not acceptable) and provides a signal to a flywheel circuit 48. The identification sequence is re-started if errors are detected. Other forms of burst sampling are described.

Title: Sound deadening constructions for selective printers
Inventor: HOFKER HEIKO
IPC: F16F15/08
Filed: 1990-07-24
Abstract: In a selective printer of the kind in which the floorpan of the case is an integral part of the structural framework of the printing assembly, measures are taken to reduce the transmission of vibration to unbroken panel portions of the case. The housing is thereby prevented from operating as a sounding-board. As shown (in plan view in Fig 2) the printing components 2 are secured to a central area of the floorpan 3, and the whole assembly is supported (e.g. upon a desk) by resilient feet 4 located at the juncture between the floorpan and the components 2. Slits 5 in the floorpan constrain sound transmission to junctions 7, and also destroy the potential of the floorpan to act as a sounding board. Immobilisation and strengthening of the floorpan during transit may be provided by U shaped shipping-clamps which engage integral formations either side of slits 5 and/or by strips which are inserted in the slits themselves. <IMAGE>
