Patent GB-2078841-A (GB)
Title: Formwork board
IPC: E04G9/00
Filed: 1981-06-25
Abstract: A formwork board (3) is made up of at least two formwork board parts (4 and 5) fitting together, whilst the separating line between at least two of the formwork board parts (4 and 5) is defined by abutment webs (12), straps or the like which, in cross section, are located in an inclined position relative to the formwork skin (11) of the formwork board (3) and to the outer edge webs (6) of these formwork board parts (4 and 5). Preferably, the formwork board parts (4 and 5) fit together to form a rectangle. The formwork board part (4) whose abutment web (12) forms an obtuse angle with the formwork skin (11) can be removed first during the stripping of the forms, thus producing a correspondingly wide form-removing gap. The removal of the first part (4) of the formwork board is made easier by the wedge shape resulting from the inclined arrangement of the abutment web (12). Thus, the forms can readily be removed even between two outgoing walls, in shafts or the like. <IMAGE>

Title: Film processor
Inventor: DOVE MICHAEL DAVID
IPC: G03D3/10
Filed: 1981-11-06
Abstract: A film processor comprises a pair of wheels (1, 2) located one above the other, an endless drive member (3) passing around both wheels, and means for driving at least one of the wheels. A bar arrangement (4) has means for carrying a film-receiving hanger (6). A lever (13) is pivotally connected at one of its ends (15) to the bar arrangement (13), pivotally connected at its other end (14) to the endless drive member (3), and pivotally connected at a point (16) intermediate its ends to a vertically reciprocatable plate (7). Movement of the endless drive member (3) causes the bar arrangement (4) to reciprocate both vertically and horizontally, thus moving film hangers 6 releasably carried by the bar 4 progressively through treatment baths. <IMAGE>
Patent GB-2089568-A (GB)
Title: Method of manufacturing photo-voltaic devices
IPC: H01L31/18
Filed: 1981-12-14
Abstract: The invention relates to the manufacture of a cadmium sulphide photo-voltaic device. A substrate such as a glass is coated with successive layers which are made, in order, of tin oxide, cadmium sulphide, cuprous sulphide and copper to build up a photo-voltaic junction. In order to achieve a fast deposition rate of the cadmium sulphide while achieving a well ordered crystal structure the cadmium sulphide layer is deposited in two stages, the first involving spraying of a weak precursor solution and the second a substantially more concentrated solution to achieve at least a five times increase in the deposition rate. The invention also describes improved techniques for spraying and reducing the effects of the resistivity of the tin oxide first electrode.

Title: Viscometer
Inventor: STANGROOM JAMES EDWARD
IPC: G01N11/10
Filed: 1983-05-10
Abstract: In a piston and cylinder viscometer suitable for investigating the rheological properties of Newtonian fluids and Bingham plastics, an undersized piston (18) is accelerated from rest down through a hollow cylinder (6) in a cylinder block (1) containing a fluid (7) under investigation, by the action of a piston rod driven from above by a piston driving means (50). Both the instantaneous pressure ahead of the piston (18) and instantaneous velocity of the piston rod are measured and recorded in phase to determine the relationship between shear stress and shear strain induced in the fluid (7) throughout the piston stroke. Pressure is measured by peizo electric transducer 16 and velocity by a magnet 33 whose poles 34, 35 move in respective opposed series windings 37, 38 which produce an e.m.f. proportional to piston velocity. By providing a conductive sleeve on piston 18 and applying a voltage gradient between it and the cylinder block, the viscometer may be used with an electroviscous fluid. <IMAGE>

Patent GB-2133073-A (GB)
Title: A central locking system for a motor vehicle
Inventor: KLEEFELDT FRANK
IPC: G07C9/00
Filed: 1984-01-10
Abstract: The system has an electronic receiver/controller and a remote actuator/transmitter incorporating an encoder having a set of different codewords corresponding to the unlocking signal, sequenced in cyclic order (1,2,...x,...,n). At each actuation, one of these codewords is transmitted, in sequence, the x-th actuation transmitting the x-th codeword. The receiver has a decoder, which counts the transmissions and only converts the x-th transmission into the unlocking signal, releasing the electronic controller if it is the x-th codeword, these cycles continuing until x=n and then returning to x=1 and recommencing. If synchronism between the encoder and decoder is disturbed, it is restored by a signal from an auxiliary encoder having a set (m) of different, auxiliary, sequenced codewords acting as synchronisation signals. When the transmitter is specially actuated, one of these auxiliary codewords is transmitted, in sequence, the x-th actuation generating the x-th auxiliary codeword. An auxiliary decoder in the receiver counts the transmissions and converts the x-th auxiliary codeword on receipt into the unlocking signal, bringing about synchronisation and also switching the receiver to the (x+ 1)th auxiliary codeword (which the transmitter is prepared to emit), until at x=m the cycle recommences at 1.

Title: Leading edge arrangements for aircraft wings
Inventor: CLIFFORD-JONES JOHN BROOKE
IPC: B64C9/24
Filed: 1984-03-27
Abstract: A leading edge arrangement includes a fixed wing portion 10, a slat member 18 slidably mounted with respect thereto by an arm 14. The arm 14 is provided with an internal trackway 15 and external cam surfaces 16 min  and 16 sec , the trackway co-operating with roller bearings 12 on the fixed wing portion and the cam surfaces co-operating with respective roller bearings 13 min  and 13 sec  on the fixed wing portion. The profiles of the trackway and cam surface are selected so that from a stowed cruise condition the slat member initially moves to a take-off setting along a path in which the ratio of downward deflection to extension movement is low to increase effective wing chord, and subsequently moves to a landing setting along a path in which the said ratio is high to increase wing camber. A modification is also described in which the rearward heel of the slat member which is exposed when the slat is extended is formed of a flexible panel portion (21, Fig. 2), so that it may blend smoothly with the remainder of the rearward surface of the slat member. <IMAGE>

Title: Production of a ceramic powder
Inventor: OZAKI YOSHIHARU
IPC: C01G49/06
Filed: 1984-10-25
Abstract: Ceramic powder is manufactured by (a) spraying and hydrolyzing, in the presence of water, at least one substance which produces by such hydrolysis a metallic or non-metallic oxide, hydroxide or hydrate and (b) calcining the products. The ceramic powder may be prepared by an apparatus comprising a spray/hydrolysis section 20 which sprays and hydrolyzes under the presence of water the said at least one hydrolysable substance and a calcining section 30 which calcines the product of hydrolysis in the spray. The sprayed substances are thus completely hydrolyzed before thermal decomposition inside a furnace and immediately calcined to achieve a final ceramic powder product. <IMAGE>
