Patent GB-2136868-A (GB)
Title: Lock blocking device
Inventor: WOJTKIEWICZ HENRYK
IPC: E05B17/20
Filed: 1982-11-02
Abstract: A blocking device for an existing lock, eg a domestic door lock, comprises a movable pin 3 to block the bolt of the lock operated by means of a "push-on"/"push- off" latching device containing a coding manipulator 4, a set of contacts for switching on an alarm system and an illumination unit, if required. The whole device is encased for protection. In use the door is locked in the usual way using a door key; using a push-on button of the latching device the cylindrical locking pin is introduced into the lock bolt. This is followed by setting the lock coding system which is dialled by means of two knobs. Before the door can be opened again a known code must be dialled first and the cylindrical locking pin must be lifted to such a height as to unblock the lock bolt. This is done by a means of a "push-off" button; only then can the door be opened with the door key. Dialling a wrong code will raise an alarm. <IMAGE>
Patent GB-2109107-A (GB)
Title: Method of and apparatus of individually cooling a plurality of rooms
Inventor: BLAHA EDUARD
IPC: F24F1/01
Filed: 1982-11-03
Abstract: In a room cooling system operating with a variable quantity of cooling air, the primary air is cooled to at least 10 DEG C below the room air temperature of the room (15) to be cooled. This cool primary air is mixed in an induction system (1) with secondary air drawn in from the room (15) before the mixed air is ejected as cooled air into the room (15). Mixing the primary air and the room air before discharge into the room (15) enables primary air temperatures to be lower; consequently, smaller volumes of primary air are required for a given removal of heat than previously, so that the air-conditioning plant can be smaller - i.e., the space taken up thereby and its capital cost and power consumption can be reduced. Also, drawing in room air in an induction system (1) ensures that the mixture ratio between primary air and secondary air remains substantially constant for the different quantities of primary air required to produce different amounts of cooling. <IMAGE>

Patent GB-2161540-A (GB)
Title: Automatic door-opening and -closing arrangement
Inventor: CHEN KUEN-NENG
IPC: E05F3/10
Filed: 1984-07-10
Abstract: The door is opened by a spring, and closed by hydraulic power. Upon door unlatching, a large spring (2, Fig. 3) pushes a hollow rack (3) to rotate a gear (4) and an arm (5) to open the door. To close the door, fluid is pumped against a piston (7) to return the rack and compress the large spring and a small spring (8). With door latching, fluid pressure is released, and the small spring, abutting a piston rod within the rack, returns the piston to enable subsequent rack movement. The pump's electric motor is controlled by:- a timer to start door closing and reset to zero by traffic stopping on a pedal switch; a latch switch to stop the pump; a fluid-over-pressure switch in case of a body jamming the door; and touch-and-turn-off switches on the door's latch-edge and bottom. Pivoted, spring-biased, anti- clamping plates (20, Fig. 6) cover the gap between the doors hinge- edge and a jamb to prevent a body being clamped. <IMAGE>

Patent GB-2147903-A (GB)
Title: Human serum albumin and its microbial production
Inventor: LAWN RICHARD M
IPC: C12N15/00
Filed: 1984-09-21
Abstract: By means of reverse transcription of mRNA coding for a desired polypeptide, there is obtained a set of overlapping fragments of duplex cDNA, which together correspond to the whole mRNA molecule. The fragments have overlapping regions bearing sites for restriction enzymes, such that cutting and ligation gives DNA corresponding to the polypeptide. This is introduced into a vector in reading frame with a promoter. Transformation of a microorganism enables expression of the polypeptide. The construction via fragments enables large molecules to be made. Thus, human serum albumin (HSA) is produced by E. coil transformed with plasmid pHSAI. This includes DNA made from fragments derived from reverse transcription of mRNA from human liver.

Title: Hydraulic injection timing mechanism for a fuel injection pump
Inventor: HOFFMAN KARLHEINZ
IPC: F16D3/10
Filed: 1984-12-11
Abstract: A hydraulic adjusting mechanism for a fuel injection pump (2), which mechanism controls the injection timing of the pump depending on various operating parameters of a self- igniting internal combustion engine, consists of a primary element (6) driven from the drive shaft of an internal combustion engine and a secondary element (5) rigidly connected to the camshaft (4) of the injection pump (2), of which elements the primary element (6) connected to a hydraulic oil supply (14) is provided with a control element (10) which, when subjected to pressure, can be displayed axially in opposition to the force of return springs. The primary element (6), which is in the form of a driver with external toothing, serves as a housing for the control element (10) which consists of a piston (8) and sliding blocks or parts (9), and the pin-like sliding block or part of which has an inclined or acute-angled face (9a) which in constant contact with the adjacent face of a cooperating piece (12) mounted in the secondary element (5).

Patent GB-2151948-A (GB)
Title: Separation equipment
Inventor: PRICE JAMES STANLEY
IPC: B07B13/00
Filed: 1984-12-21
Abstract: An apparatus 10 for separating worms from a worm-containing medium comprises an upwardly-moving spiked conveyor 12 receiving the medium from a hopper 14. In operation, worm free material will run down between the spikes 30 into a first receptacle 20 whereas worms clinging to the spikes will only leave the conveyor when they slip down the inverted spikes of the return run of the conveyor to fall into the worm receptacle 21. In an alternative embodiment, the separating mechanism is provided by an internally-spiked drum member into which the medium is loaded. As the drum rotates, the internal surface of the drum becomes increasingly steep until at least the bulk of the medium is left behind. The worms, on the other hand, become draped over the spikes on the drum until these become sufficiently inverted for the worms to slide off on to a collection belt running down the centre of the drum. <IMAGE>

Title: Picture input equipment
Inventor: SAKAMOTO TAKASHI
IPC: H04N1/401
Filed: 1985-02-25
Abstract: The signals from the cells of a CCD sensor array, in e.g. a camera (1), are individually corrected by dark and full white reference signals. The dark signals for each cell is read and stored in memory (5). Later, when white reference signals or picture signals are output by camera (1), the stored dark signals are subtracted by circuit (4) and the resultant signal is converted to its logarithm by circuit (7). The white reference signals, after logarithmic transformation, are stored in memory (12), ready for subtraction from the logarithmic picture signals in circuit (10). If the dark signals are small, their average may be subtracted from the signals from all cells, making memory (5) redundant. <IMAGE>

Abstract: A central belt lock for safety belts, especially for pilots and other aviators or for parachute jumpers and a lock housing with a hook- shaped bead 14, above which is disposed a tiltable holding disk 28 which must be uniformly spaced from the bead for complete opening of the lock. With such locks there exists the problem of providing the locking member with a merely rotatable operation. To resolve this problem, the locking member is preferably embodied as a rotary disk 30 or other rotary member and is connected with a cam member 33, which controls the movement of the tiltable holding disk 28 by means of guide members 41 in the form of pins mounted on a stud 18 which is secured to the housing. The guide members 41 appropriately slide or make contact with the cam surfaces when the rotationally operable device is moved. <IMAGE>
