Patent GB-2112663-A (GB)
Title: Disposable air cleaner
Inventor: ALSETH STEVEN M
IPC: B01D46/52
Filed: 1982-07-23
Abstract: Disposable air cleaner (10, 110, 210, 310) for a variety of machines such as small engine (12). Engine air cleaners are of various sizes and shapes and many use replaceable filter elements which must be stocked in a variety of sizes. Such filter elements may permit air leakage since their seals are subject to misalignment and wear. The invention solves these problems with reusable intake tube (14, 114, 214, 314) mounted on the machine or attachable to a mount on the machine to support the air cleaner. Air leakage is reduced by eliminating all but one seal required to attach the cleaner to the tube. The intake tube (14, 114, 214) has an air permeable portion (14b, 114b) received within the bore of tubular filter element (20, 120, 220) to form the inner support for the air cleaner (10, 110, 210). Cleaner (10) includes a shell (22) spaced from and surrounding element (20), one end cap (24) closing element (20), shell (22) and tube (14) at one end, another end cap (26) closing element (20) and shell (22) at the other end and having an aperture (28) through which tube (14) is inserted, and air intake apertures (36) in one end cap (24, 26). Cleaner (110) includes deflecting blades (160) in the space (123) between shell (122) and element (120) and a removable dust collector cap (154). Cleaner (210, 310) exposes the filter element (220, 320) by eliminating the shell. Alternatively, tube (314) neither includes the air permeable portion nor extends into the filter element (320) but rather a screen (319) affixed to the end thereof extends into filter element (320). The cleaner (10, 110, 210, 310) is attached to tube (14, 114, 214, 314) by a flexible flange (30, 130, 230, 330) extending outwardly from end cap (26, 126, 226, 326). A clamp (32, 132, 232, 332) seals the flange (30, 130, 230, 330) to the tube.

Title: Plate freezer
Inventor: FENNER FRANK RICHARD
IPC: F25D31/00
Filed: 1983-04-08
Abstract: An automatic plate freezer comprises a plurality of freezer plates (A-I) which rest on a lower support (44) connected by ties (43) to an upper support (41). Each plate rests on the plate below via adjustable spacers (46) and the upper support (41) may be raised and lowered by jacks (42). In use, product to be frozen is loaded on the plate located at a loading level determined by sensors (48) and the spacers associated with that plate are set to a value appropriate to the product in question. The jacks (42) are then extended to lift the stack of plates (A-I) until the plate just loaded is engaged by latches (47). The stack is then lowered, and the latches support all plates at and above the level of the latches. Lowering of the remaining plates continues until the sensors (48) detect that the plate below that just loaded is at the loading level whereupon the cycle repeats. <IMAGE>

Title: Fluid flow control apparatus
Inventor: EDWARDS JOHN GRIFFITHS
IPC: F24D19/10
Filed: 1983-06-27
Abstract: A fluid-flow control apparatus used in the control of a domestic hot water and central heating system includes a multi-way valve (Figs. 1 and 2, not shown) having an inlet port connected to a boiler, and a valve member movable between a first outlet port connected to a radiator circuit and a second outlet port connected to a hot water circuit, a spring urging the valve member towards the first outlet port. An a.c. synchronous motor 3 drives the valve member towards the second outlet port by way of a switch-operating element arranged to operate non- simultaneously two microswitches 11 and 12 controlling operation of the motor 3. The microswitches are connected to a room thermostat 23 and a cylinder thermostat 25. In an intermediate position of the valve member, and with both thermostats 23 and 25 demanding heat, the a.c. driving current to the motor 3 is supplied only through a resistor 21, so that the motor 3 is supplied with a.c. of a reduced power, to bring the amplitude of the motor output force to such value that the valve member stalls in the intermediate position. <IMAGE>

Title: Integrated transistors protected against overvoltages
Inventor: VERSIGLIA FELICE
IPC: H01L27/06
Filed: 1983-08-05
Abstract: A planar transistor of bipolar type 7,3,2 is protected against overvoltages by a second emitter region 8, connected ohmically to base 3, and a second base region 4 which is not directly connected to any electrode of the transistor and is therefore floating with respect to the potentials applied thereto. The second emitter region and the second base region form, together with the collector 2,1 of the transistor, an auxiliary protection transistor. The resistivity of the second base region is suitably regulated such that the collector-emitter breakdown voltage of the protection transistor, with the base of that transistor unconnected, has a lower value than that between the collector and the first base region or first emitter region. The protected transistor may be integrated in a Darlington type amplifier. <IMAGE>

Title: Vehicle guidance and control system
Inventor: STEPHENS PHILIP EDWARD
IPC: G01S17/87
Filed: 1984-05-10
Abstract: A vehicle guidance and control system has a number of trucks (2, 3) whose movement is controlled by a base station (4). Each truck periodically fixes its own position in relation to marker boards (8) consisting of patterns of reflective coded stripes by scanning a narrow laser beam (14) in a predetermined direction across the stripes. Using at least two boards its position can be determined by triangulation, and because the beam scans in a fixed direction, the positional accuracy can be determined by a particular stripe or edge of a stripe, and not by the size of a marker board as a whole. <IMAGE>

Title: A fire and smoke damper
Inventor: LOUGHRAN FRANCIS MALACHY
IPC: A62C2/16
Filed: 1984-12-07
Abstract: A fire and smoke damper 1 comprises a plurality of stainless steel slats 2 each having inturned longitudinal edges for interengaging with the adjacent inturned edges of an adjacent slat 2 to form a folding shutter-type mechanism. Each of the slats 2 is formed with a longitudinally extending central rib 6 for improved structural strength and heat resistance. The slats 2 are retained in a folded, retracted position by a two-part fusible link 4. In the event of fire the link 4 breaks and the slats 2 move into a released position closing an opening in which the damper 1 is mounted. Biasing means providing two springs, each comprising a strip 20 of spring steel reeled around a shaft 22 at one end and connected at the other end to the lowermost of the slats 2, ensures that when the fusible link is broken the slats 2 close the opening regardless of the position or orientation of the damper 1 in a duct. <IMAGE>

Title: Vehicular brake system with a hydraulic brake power booster
Inventor: BUSCHMANN GUNTHER
IPC: B60T8/44
Filed: 1986-06-25
Abstract: For servo pressure supply, a brake system with a hydraulic brake booster (1) comprises a pressure accumulator (11) and an electromotively driven pump (9, 10) which will be switched on during brake application or when the accumulator pressure has fallen under a threshold value. Upon commencement of a braking action, the brake booster (1) is fed by the pressure accumulator (11). Charging of the pressure accumulator (11) with pressure fluid out of the pump (9) is inhibited initially to ensure that the entire pump capacity is available for brake force boosting. However, as soon as the pump pressure has risen, the surplus pump output will be made use of for recharging of the pressure accumulator (11) during the braking action by means of a differential-pressure valve (12) responsive to booster output pressure, through line 20, and to pump pressure. Upon attainment of the accumulator pressure, an electro-valve (16) establishes a connection to a low pressure-supply reservoir (18). <IMAGE>
