The cartridge 19 can be mounted within the seat 21 at a first position with a mercury-containing bulb 23 in the cartridge 19 inclined in one direction and at a second position, rotated through 180 DEG  on the plane relative to said first position, with the bulb 23 inclined in the opposite direction, with either the earth or ground contact 17, 17' of the lampholder 1 engaging a contact 26 in dependence upon the desired position of the cartridge 19. <IMAGE>
Patent GB-2050154-A (GB)
Title: Hospital beds
IPC: A61G7/10
Filed: 1980-05-08
Abstract: An arrangement, e.g. for transferring a patient between a bed and a stretcher trolley, intended to be mounted on a bed having a mattress arrangement (3) and a sheet (24) or the like arranged to be placed on said mattress includes a pivotable (9, 13) sheet frame structure (15-19), detachably carrying (20-3) the sheet (24), whose pivotal movements when the sheet is swung from the mattress are controlled by a pivot arm mechanism (8, 11, 12). Arranged between the bed and the sheet frame structure is a spring mechanism (6). This comprises a gas spring (37, 40, 42) which can be locked in any desired position and which in a released position exerts a force such as to substantially balance the weight of a patient resting on the sheet during swinging. The spring mechanism also includes a spring means (59), e.g. a compression spring, which is coupled in series with the gas spring via latching means (50, 51, 52). The latching means are arranged to release the spring means (59) when the sheet is partly relieved of the patient's weight on reaching a position A partially contacting the mattress and when the gas spring is locked, spring (59) permitting further swinging of the sheet towards the mattress to a position B in which it can be released from the frame structure. <IMAGE>

Title: Repair of kegs and casks
IPC: B23P6/00
Filed: 1980-05-20
Abstract: In the repair of a metal beer keg or cask 100 the latter is cut circumferentially into two end parts 106, 107 by means of a band saw 103 mounted in a jib 104. During this cutting operation the keg or cask 100 is mounted in a rotary fixture 105 below the jib 104 which engages the outer surface of the keg or cask 100 to act as a depth stop for the saw 103. The parts 106,107 are then separately reshaped on a radially expanding mandrel to restore the correct shape and internal volume. After reshaping the parts 106, 107 are welded back together, by a continuous seam weld, to provide a renovated keg or cask. An intermediate portion may be welded between the two parts. <IMAGE>
Patent GB-2052815-A (GB)
Title: Digital frequency multiplier
IPC: G06F7/68
Filed: 1980-05-22
Abstract: A digital frequency multiplier which includes a counter 2 for counting the number of clock pulses from generator 5 having first been divided by N in divider 6. The counter 2 establishes the number of these pulses which occur during a cycle of the incoming frequency and this number is compared in comparator 3 with the count from a further clock counter 4. Typically when coincidence occurs a change of state of comparator 3 results and as this coincidence will occur N times during a cycle of the incoming frequency, the output repetition frequency from comparator 3 will be N times the incoming frequency. Although division is shown prior to counter 2 this can be provided after this counter by using an arithmetic divider. <IMAGE>
Patent GB-2053513-A (GB)
Title: Circuit arrangement for driving a movable element
IPC: E05F15/41
Filed: 1980-06-17
Abstract: A safety control circuit for electric motors of power windows of automotive vehicles and which differentiates between a tight fitting of the window pane and an obstacle blockage. The motor current is selectively detected to provide a signal representative of the instantaneous rather than static current values. The detected signal is compared to a reference signal. When the detected signal exceeds the reference signal by a given value or longer than a predetermined interval, which indicates that an obstacle blockage has occurred, the motor current is switched off or reversed.
Patent GB-2056801-A (GB)
Title: Synchronizing an oscillator from a television signal
IPC: H04N5/05
Filed: 1980-08-01
Abstract: In a television signal receiver the synchronizing signal is separated at 2, and applied to a pulse shaper 3 to provide discrete pulses coincident with the synchronizing pulses. These discrete pulses are applied to phase discriminator 4 along with pulses derived from an oscillator 7, controlled by the output of the phase discriminator 4. The oscillator 7 produces a pulse train which is frequency divided in a divide-by-20 stage 8 and a divide- by-2 stage 9 to produce pulses at line frequency which are applied through the normal closed contacts of a switch 11 to the input 6. During the period in the field blanking interval when the pre- and post- equalizing pulses of twice line frequency are present the switch 11 provides a path between the output of divider 8 and input 6 to apply twice line frequency pulses to that input. The action of the switch 11 is controlled by a gate 12 controlled from the television signal. The arrangement accelerates pull-in synchronization of the oscillator 7 during the field blanking period. <IMAGE>

Title: Spanner for nuts and bolts
IPC: B25B13/06
Filed: 1980-09-12
Abstract: A spanner for nuts and bolts comprises a lever (10) with a transversely- mounted sleeve (14) at one end thereof, and a shaft (16) rotatably and axially slidable mounted in the sleeve (14) and provided at one end with a removable socket (18). A handle (20) in the form of a wing nut is fast with the end of the shaft (16) remote from the socket (18). Cooperable polygonal cross-section (24) on the shaft and a like apertured ring (26) in the sleeve enable the shaft and sleeve to be selectively coupled for rotation by axial displacement of the shaft (16) relative to the sleeve (14). When the shaft (16) is in its uncoupled position, the initial screwing up of a nut or bolt can be quickly effected by using the wing-nut handle (20); thereafter, the sleeve (14) and shaft (16) can be coupled to enable the lever (10) to be used in the final tightening of the nut or bolt. A spring pressed ball (38) locates in grooves (28, 30) for shaft coupled and uncoupled modes. <IMAGE>

Title: Flange seal
Inventor: MICHAELIDES CONSTANTINE
IPC: F16J15/14
Filed: 1982-10-02
Abstract: A gas meter casing (11) has two facing flanges (11', 12') and a third flange (13') therebetween The third flange is formed at a small angle e.g. between 5 DEG  and 7 DEG , to the facing flanges. To seal the flanges together beads (15, 16) of a silicone rubber gasketting material are formed on the facing surfaces of the outer flanges and the sandwich pressed together. The gasketting material is thus forced to flow into the tapered spaces formed at each side of the centre flange. The tapered shape of the gaskets conveys both the advantage of a narrow gap (less leak potential) and a thicker gasket (more resistance to damage). <IMAGE>
