Patent GB-2126040-A (GB)
Title: Navigation apparatus for land vehicles
Inventor: MULLER PAUL
IPC: G01C21/28
Filed: 1983-07-25
Abstract: Signals produced from one or more transmitters of known position, e.g. satellites of the "Global Positioning System" are received by a receiver 1 of a land vehicle, are evaluated and a mean value is formed. A direction sensor 7 and a distance recorder 6 produce separate direction and distance signals which are fed to a computer 4, which by means of the dead reckoning navigation method determines therefrom the position of the vehicle which is indicated by an indicator 5. For the correction of the indicated position of the vehicle the indicator 5 is adjusted at predetermined time intervals to the mean value of the signals received from the more accurate receiver 1. <IMAGE>

Title: Drawer interlock mechanism
Inventor: KURZ GEORGE FREDERICK
IPC: E05B65/463
Filed: 1983-09-21
Abstract: A drawer interlock for permitting either one of two drawers mounted in a frame (12) to be slideably withdrawn from the frame but preventing both drawers from being withdrawn together. Each drawer carries a rearward projection (61, 62) adapted for engagement with a sliding member (63) on the frame (12), the arrangement being such that as either one of the drawers is withdrawn, its associated projection (61) cams the sliding member (63) to a position in which it locks the projection (62) of the other drawer against withdrawal, and that as the drawer is replaced, its plunger cams the sliding member to a position in which either one of the drawers may be withdrawn. The sliding member (63) has an aperture (69) having vertical edges (67, 68) which are engageable respectively by cam portions (71, 72) of the projections as the drawers are withdrawn or replaced and engageable by a locking notch portion (73) of the projection (62) when the drawer carrying the other projection (61) has been withdrawn from the frame. <IMAGE>

Patent GB-2152986-A (GB)
Title: Equipment for use on uneven or inclined surfaces
Inventor: MARTIN ROBERT GEORGE
IPC: E02D7/08
Filed: 1983-12-14
Abstract: A piling rig (1) for use on the sea bed for embedding an anchor has a central frame (2) and four legs (3). Each leg (3) comprises an inner leg member (20) telescopically mounted within an outer leg member (29), and a hydraulic cylinder and displacement member. The cylinders are connected by way of respective non-return valves to a common hydraulic accumulator having a piston the movement of which is limited by an internal constriction in the cylinder. As the piling rig is lowered onto the sea bed, the weight of the rig forces fluid from the cylinders into the accumulator until the piston is displaced sufficiently to encounter the constriction (17), the legs then being locked in position as no further fluid can be displaced and no fluid can return through the non-return valves. The non-return valves are by-passed by further, oppositely arranged, non-return valves in series with an ON/OFF valve to allow fluid to return to the legs when the rig is lifted from the sea bed. <IMAGE>

Title: Logic circuits
Inventor: SAUL PETER HENRY
IPC: H03K19/094
Filed: 1984-08-23
Abstract: An integrated injection logic circuit of the type comprising a bipolar switching transistor (ST) and having a base-feed/collector load. To improve speed of switching, and to allow dense packing of logic components, a junction field-effect transistor (LJ) is incorporated as load between collector voltage line and the base of the switching transistor (ST). The gate of the junction field-effect transistor (LJ) may be referred to collector voltage (Vcc) (Figure 3). Alternatively, to allow selection of switching speed, the gate may instead be referred to a reference voltage (VR) (Figure 4). A logic array may be assembled from a plurality of circuits as above, and gates may be connected in common to reduce the number of input contacts required. Common connection may be afforded by means of a heavily doped semiconductor track extending across the junction field-effect transistors (LJ). <IMAGE>

Title: Containers with plastics labels
Inventor: FUMEI JOHN GIANCARLO
IPC: C09J7/02
Filed: 1984-10-15
Abstract: The present invention provides, without the drawbacks accompanied by the use of hot melt adhesives, a labelled container (8), the label (10), on its underside (22) that is adjacent the container (8) when applied, being provided with a finite area (65) on its leading edge (25) and a finite area (66) on its trailing edge (27), by applying thereto a solvent for the polymer in each of the finite areas (65, 66), the finite areas comprising a viscous tacky solution of the polymer in the solvent, the solidifying solution being sufficient to tack and bond the label (10) to the container (8) during wrapping. After the label (10) is wrapped around the container (8), the bond between the container and label becomes weaker as the solidifying solution hardens so that later the label can be easily and cleanly stripped from the container for recycling. The label can be a coextruded plastics label having a solid polymer layer (15) that is printable and a foam polymer layer (22), the finite areas being on the foam layer.

Title: Computerized parcel shipping system
Inventor: HILLS KAREN F
IPC: G06Q40/00
Filed: 1986-10-15
Abstract: Transactions related to a plurality of parcel carriers are recorded in a single logging file. The file has a pair of counters for each carrier, with the first counter storing the total number of transactions recorded for that carrier and the second counter storing the number of closed transaction records for that carrier. The programs enable the archiving of the records (Figures 2, 3), and updating the records (Figure 4) of the file. A closed transaction corresponds to a parcel which has been shipped, an open transaction corresponding to a parcel assigned to a carrier, but not yet picked up for shipment, the total corresponding to the sum of the two. Thus many carriers may be catered for on a single logging file (Figure 5), although larger carriers may have dedicated files, (UPS, US PS Figure 5). <IMAGE>
