Title: Oil filter with by-pass valve
Inventor: SUNDHOLM GORAN
IPC: B01D35/147
Filed: 1989-04-19
Abstract: An oil filter comprises a tubular, inward-flow filter element 2 in a casing 1 and a by-pass valve 30 located at one end of the casing, which opens if the oil pressure in space 10 rises sufficiently. The valve comprises a plate 18 carrying a knife-edge seal 19 which normally seals against casing end 5. Bolts 21 carry springs 22 which urge plate 18 upwards, while a toroidal spring 24 holds the filter element and allows oil pressure from space 10 to act on the upper face of plate 10, radially outside seal 19. Plate 24 and attached sleeve 26 are moved downwards by excess pressure to allow oil to bypass element 2. <IMAGE>

Title: Power transmission apparatus for a four-wheel drive vehicle
Inventor: HAMADA TETSURO
IPC: B60K17/35
Filed: 1990-11-12
Abstract: Power transmission apparatus for a four-wheel drive vehicle, comprises an engine (1) for directly driving a primary driven axle, and a torque transmission device (7) for transmitting drive torque from the primary driven axle to a secondary driven axle as required, according to a difference in the rotational speed between the front and rear axes (4, 10). The torque transmitted between the front and rear axles (4, 10) is reduced for a given difference in the rotational speed between the front and rear axles (4, 10) as a vehicle speed is increased, or the difference between the axle speeds required to transmit a given torque is increased as the vehicle speed increases. Thereby, the unnecessary burden of load on the rear axle members is reduced. The torque transmission device (7) comprises a structure for limiting the upper limit of the torque which can be transmitted to the secondary driven axle. <IMAGE>
Patent GB-2249902-A (GB)
Title: Standards conversion
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: G11B27/034
Filed: 1990-11-15
Abstract: A VTR 11 provides a slow-motion digital video signal to a standards converter 12, which supplies an intermittent output to a frame recorder 13, which in turn supplies a normal speed output intermittently to a VTR 14. In order to prevent re-cuing of the VTR 14 hindering the rate of conversion by the converter 12, a pair of frame recorders 13A, 13B may be provided, and when either is outputting to the VTR 14, the other records the output of the converter 12. In order to obviate the need for a slow-motion VTR 11, the VTR 11 may supply its signal intermittently at normal speed to a frame recorder 11A (Figure 73), which then repeats fields output to the converter 12 to effect slow-motion play-back. So as not to hinder continuous conversion by the converter 12, two such frame recorders 11B, 11C (Figure 74) may be provided, and when either is outputting to the converter 12, the other may be storing the output from the VTR 11. In order to reduce the number of times the VTRs 11, 14 start and stop, conversion may be carried out in two phases (Figure 72). In the first phase, the output of the converter 12 is recorded in a predetermined scrambled order on the VTR 14, and in the second phase the scrambled recording is played back a number of times by the VTR 11 through the frame recorder 13 to the VTR 14 to reorganise the fields into the proper order. <IMAGE>

Title: Overhead conveyors.
Inventor: DEACON KEITH EDWARD
IPC: B65G17/20
Filed: 1992-02-22
Abstract: An overhead conveyor, of the general kind that may be used to move goods through a workplace to create an automated or semi-automated production line, comprises a cyclic track 1 of generally rectangular section, housing an endless chain 2. The links of the chain are wheeled bogeys, the wheels of alternate bogeys being in the horizontal and vertical planes in an alternating sequence. Pendant workpiece carriers 15 extend in cantilever from some or all of the bogeys 2 whose wheels are in the vertical plane, through a continuous longitudinal slot 3 in a vertical side wall of the track 1. The conveyor of the invention is significantly cleaner in operation than conventional conveyors, avoiding oil spillage from the moving chain onto the floor area below. The use of the conveyor is therefore potentially extended to clean environments, such as retail premises or food processing plants, where previously aesthetics or hygiene laws had made the use of overhead conveyors inappropriate. <IMAGE>

Title: Interlock controlling engagement of paper tractor with printer.
Inventor: KATO HIROYUKI
IPC: B41J11/26
Filed: 1992-06-12
Abstract: To prevent simultaneous mounting of two tractor units (15) on both an upstream side and a downstream side of the platen (5) of a printer, a rocker member (64) is pivotally mounted by a pivot pin (65) on a side plate (3a) of a chassis (3) to which the tractor unit is attachable. The rocker member has an upper end portion (64a) disposed close to an upper lock pin (25) of a downstream side mounting portion. The lower end portion (64b) of the rocker member is disposed close to a lower lock pin (26) of an upstream side mounting portion. When the tractor unit is locked with the lower lock pin, the lower end portion of the rocker member is firmly locked in position against rotation, so that the upper end portion of the rocker member is no longer separable from the upper rock pin, and hence, is able to prevent another tractor unit from moving into that portion. <IMAGE>

Patent GB-2265772-A (GB)
Title: Arc welder operable from A.C. supply of either relatively high or low voltage
Inventor: KARINO KUNIO
IPC: B23K9/073
Filed: 1993-03-09
Abstract: The welder has inverters (14), (16), (Fig 1), powered respectively by smoothing capacitors (6), (9) which are normally connected in series across a rectifier (2) when the A.C. supply thereto is at a higher voltage (eg. 400 volts) but are switched to parallel connection by a relay 10 if a control circuit 12 senses that the A.C. supply is at a lower voltage (eg. 200 volts). The control circuit 12 senses the A.C. voltage by means of a zener diode 38 responsive to the rectified output of a control transformer 25, the lower A.C. voltage causing energisation of a relay 34 which in turn energises relay 10 and switches primary windings 25a, 25b of transformer 25 from series to parallel. A latch circuit 45 holds relay 34 energised regardless of the increase in the output of transformer 25 caused by this switching. The control circuit thus far described functions adequately for A.C. supplies of substantially constant voltage. However, the gradually rising output produced on starting of an engine-driven generator (60) would result in the inverter (14), (16) being maintained in the parallel connection on a generator output which has risen through the lower voltage to the higher voltage. A zener diode 64 is therefore provided which responds to the A.G. supply being above the lower voltage by energising a relay 62 to open contacts (61) at the output of the generator (60) thereby momentarily de-energizing the control circuit 12 causing circuit 45 to unlatch resulting in the series connection of inverters (14), (16) on reclosing of contacts (61). <IMAGE>
