Title: Glass Ceramic Hob including Temperature Sensor
Inventor: PEPPER MICHAEL ANTHONY
IPC: F24C15/10
Filed: 1983-09-26
Abstract: A glass ceramic cooker hob includes, as a temperature sensing device, an electrical resistance temperature detector which is in contact with the glass ceramic. A signal from the detector is used to control the energy supplied to a hob-heater element. A further signal is generated when the temperature of the hob exceeds a predetermined value.

Title: Means for and methods of homing under radar signals
Inventor: DANO PAUL K
IPC: G01S13/74
Filed: 1983-09-28
Abstract: A radar or sonar guide homing system for aircraft, ships, etc., makes periodic distance measurements between a stationary transponder location (56) and a mobile interrogator location (50). An "on course" signal (90) is given when the difference  DELTA R between successive measurement readings is maximized, in a negative direction (i.e., the gap between the stationary and mobile locations is closing). Otherwise an "off-course" signal (86) is given. An "S-turn" manoeuvre confirms the accuracy of the readings. <IMAGE>

Title: Support device for solar panels
Inventor: PANTON JOHN ROBERT
IPC: H02S20/10
Filed: 1984-01-05
Abstract: A support device for one or more solar panels so that the active surface of the solar panel(s) can be maintained substantially normal to the rays of the sun, comprises a first ground engaging member (11) which is preferably of inverted T-shape with the stem of the T forming a mast (13) and a kinked solar panel supporting member (1) having two inclined arms (3, 5). One arm (3) supports the solar panel(s) while the free end of the other arm (5) is located at ground level. The free end of the first arm is slidably supported on the mast so that the orientation of the panels can be adjusted both for latitude and season. The solar panel(s) are rotatably supported on the first arm (3) so that they may be adjusted as in azimuth, locking means being provided to hold the panels in their adjusted position. The locking means may comprise a depending stay (38) on the first arm (3) and a semi-circular locking sector (32) associated with the panel(s). A quick-release coupling may be provided to enable the panel(s) quickly to be removed from the support device. The second arm (5) of the panel supporting member may be connected to a ground engaging member. Suitable stays and anchoring means are also provided. The whole support device is designed to be made up from standard water pipe which may be cut to length and connected together with sleeve-like connectors, most of which are off-the-shelf and incorporate grub screws for securing the connectors to the ends of the lengths adapted from off-the- shelf components. <IMAGE>

Patent GB-2179400-A (GB)
Title: Self-priming pump
Inventor: HIRAKAWA NORISHIGE
IPC: F04D9/02
Filed: 1986-07-09
Abstract: A communication hole is bored through a partition member which divides an intake-side priming fluid chamber from a discharge-side priming fluid chamber, whereby the two chambers are connected. The communication hole serves to prevent, on a predetermined level, a backflow of a pump fluid due to siphonage caused on the intake side when pumping operation is stopped, thereby securing a priming fluid in a pump casing. A valve assembly including a valve member is disposed corresponding to the communication hole. The valve member, which is always urged to an open position, is moved to and held in a position where it is caused to close the communication hole by the action of the pump fluid flowing in a feeding direction during pumping operation. When the pump is stopped to cause the backflow of the fluid, the valve member is moved back to the open position by the urging action.

Title: Roof truss sling
Inventor: MCLAREN RAYMOND JOHN
IPC: E21D11/00
Filed: 1986-09-01
Abstract: A roof truss sling has an open ended sleeve 7 which has a wire strand passed through it and attached to bolts 6 fixed in the mine roof. The sleeve 7 is distorted so as to simultaneously crimp the sleeve to the wire strand and also shorten its length. The shortening of the length of the sleeve 7 applies a tensile force between the roof bolts 6 through the wire strand. This tensile force serves to compress the mine roof material and thus acts to truss the mine roof. <IMAGE>

Title: Liquid fuel injection pump
Inventor: THORNTHWAITE IAN ROY
IPC: F02M55/00
Filed: 1987-04-27
Abstract: A liquid fuel injection pump of the rotary distributor type has a first groove 30 on the distributor member 12 for registration with fuel supply ports 32 and a second groove 31 for registration with outlet ports 34.

Title: Residual current circuit breakers for sockets
Inventor: SEWELL ANDREW
IPC: H01R13/713
Filed: 1988-05-11
Abstract: A RCCB comprises an outgoing supply socket, a circuit breaker mechanism for interrupting the flow of current to the supply socket in response to a fault signal, and means responsive to the absence of a plug (1) in the supply socket for reducing the energy required to close the contacts (8,9) of the breaker mechanism. The reduced energy requirement is achieved either by reducing the contact gap of the breaker mechanism or by reducing the magnitude of a biasing force tending to open the contact gap. As shown, removal of the plug (1) allows the socket shutter (2) to be spring-biased to the left, to move the contact (9) closer to the fixed contact (8) and hence allow the electromagnet (4) to reclose the contacts without manual intervention. Alternatively, a spring is provided between the movable contact (9) and the shutter (2) to provide contact bias to the open position in conjunction with the armature spring. On plug removal, the shutter movement reduces the bias provided by the contact/shutter spring. A further contact can be provided on the shutter (2) for closing with the movable contact (9) in the absence of a plug, for test purposes. <IMAGE>
