Patent GB-2094076-A (GB)
Title: Dc to dc converters
IPC: H02M3/158
Filed: 1981-07-16
Abstract: The converter produces a d.c. output voltage from a lower d.c. input voltage and is arranged so as to minimise the ripple voltage present on the output and the ripple current which is present at the input. Instead of using a single switch to chop the input voltage in the conventional manner, two serially connected switches (S1, S2) are used with one switch being 180 DEG C out of phase with the other. A capacitor (C1, C2) is connected across each switch and because of the 180 DEG C phase shift, the two voltages across each capacitor do not add arithmetically. By correctly choosing the output voltage in relation to the input voltage, the ripple values can be reduced to negligible levels without the need to increase the value of the associated reactive components. A converter circuit which is capable of handling power flowing in either direction is described. <IMAGE>

Title: Thermally clad metal section for glazing frames
IPC: E06B3/26
Filed: 1981-08-11
Abstract: Thermally clad metal section comprises metal section (10) (for example, of an aluminium alloy) and cladding section (12) (for example, of a PVC plastics material) of relatively low thermal conductivity. The metal section comprises two oppositely and outwardly projecting lips (20, 24) which can be received in two oppositely and inwardly facing channels (38, 40) of the cladding section. To secure the clad section together, a resilient neoprene cord (46) is inserted into one of the channels (38) and one lip (20) is inserted to engage the cord. The other lip is forced against an outer surface (62) of the cladding section to slide over the surface, with compression of the cord (46), and snap home into its channel (40). The cord (46) serves both to retain the lip (24) in its channel (40) and as a seal between the metal and cladding sections.

Patent GB-2087050-A (GB)
Title: Hydrostatic Transmission Control System
IPC: F02B3/06
Filed: 1981-11-05
Abstract: Diesel engine (1) drives a vehicle transmission pump (4) and an auxiliary pump (6a) which delivers control fluid to servo-valve (19) via a unit (10) producing an engine speed signal (pst) applied via reversing valve (47) to a servo-valve control piston (34 or 35). The servo-valve controls transmission pump displacement via a servomotor (5) having a feedback link (28), and the speed signal (pst) is opposed by pump delivery pressure (pH1 or pH2) to avoid undue drop in engine speed when the load on the transmission motor (8) increases. A second auxiliary pump (6) supplies lifting or other equipment (48). During overrun, the piston (34 or 35) not subject to the speed signal is lifted clear of the servo-valve to permit hydrostatic braking responsive to the speed signal (and engine accelerator (2)). <IMAGE>

Title: Poultry processing apparatus
IPC: A22C21/00
Filed: 1982-03-25
Abstract: A plurality of processing tools such as vent slitters, washers or eviscerating tools are mounted on a tool carrier (cylinder 11) movable linearly to and from points A and B along rod (9) parallel to but spaced from a conveyor 1, in synchronism with the conveyor whilst carcasses suspended from the conveyor are processed by the tools in the operative position (dotted lines in Figure 2). The tool carrier is moved from an inoperative position (solid line in Figure 2) to the operative position by cams (39) controlled by conveyor movement detected by star wheel (40). The first cam opens valve (28) to start linear movement of the carrier and of connected lug (12) which moves down incline (15) to move carrier to operative position. Second cam allows lances (24) to move down into carcass and third cam allows water to be supplied. Carrier is returned to inoperative position as the lug moves up incline (17) and is subsequently returned to point A. Alternative forms of mounting and moving the carrier are disclosed e.g. on entraining lever on tool carrier engages the conveyor and is moved therewith until the lever encounters a release pin after which the carrier is returned to its first position using a spring. <IMAGE>

Title: Stroboscopic engine fuel-injection timing
Inventor: HITCHCOCK KEITH NORMAN
IPC: F02B3/06
Filed: 1982-06-21
Abstract: Fuel injection is detected from pulses of sound at or near 40 KHz from the region of the fuel injection and a first series of pulses representing the instants of fuel injection is produced. A second series of pulses is derived from the first series and used to control a strobe lamp flashing on a rotating timing marker of the engine. The timing of the second series of pulses is adjusted until the strobe lamp flashes at the instants that the timing marker passes a stationary reference marker. The timing relationship between the first and second series of pulses then indicates the timing of the fuel injection. A microphone (11 or 51, Fig. 2 or 3) is clamped to the fuel injector or its fuel pipe or aimed at the injector to detect the ultrasonic pulses.

Title: Patient lifting and hoist therefor
Inventor: JAMES DAVID RICHARD
IPC: B66C23/48
Filed: 1984-05-29
Abstract: A method of lifting a patient from a seated to a generally standing position, e.g. for toileting, employs a hoist comprising a support column 2 mounted on a mobile chassis 3. A pivotal lifting arm arrangement 11 projects from the column 2 and presents laterally spaced attachment points 13 for a padded sling 14 which is passed around the back of the seated patient 10 below the arms thereof. The hoist is positioned with knee abutment means 15, which are mounted on the column 2, located against the knees of the patient 10 and the feet of the patient 10 are placed on footrests 16 mounted on the chassis 3 on opposite sides of the column 2. A lifting mechanism 17 comprises a pivotal operating lever 18 connected to the arm arrangement 11 through a mechanical linkage which provides a mechanical advantage, such that operative movement of the lever 18 through 180 DEG  from an upwardly projecting to a downwardly projecting position pivots the arm arrangement 11 upwardly through an angle of 60 DEG  to 65 DEG  thereby raising the seated patient 10 to a standing position on the footrests 16 while supported at the back and laterally located by the sling 14. <IMAGE>
