Title: Allyl isothiocyanate and vegetable oil contg. compsn. - having rubefacient activity
IPC: A61K31/26
Filed: 1980-11-14
Abstract: A pharmaceutical compsn. comprises allyl isothiocyanate (I) and a vegetable oil. The compsn. is for topical use. (I) is generally used as an oil of mustard or of horseradish, and the compsn. may e.g. contain 1 pt. of oil of mustard to 50-1000 pts. of a vegetable oil such as olive, peanute, corn, soya or girasol oil. The compsn. is generally applied to a dressing which is positioned over the affected part and then compressed against the skin. For certain treatments, an orbital compression chamber such as that disclosed in U.S. Pat.No.4193401 may be used. (I) may be used in conjunction with another drug such as an antibiotic and when thus used it not only provides a greater blood flow but also a greater absorption of the other drug. The compsn. helps to increase the blood flow to an internal injury, inflammation or diathesis. The vegetable oil attenuates undesirable effects of (I) and allows (I) to be maintained on the body for a longer period of time than compsns. contg. (I) in alcohol.

Title: Burglar alarm sensor switch circuit - uses two=way switches providing only temporary interruption of circuit to maintain operation after one intrusion
IPC: G08B29/06
Filed: 1980-12-03
Abstract: The alarm detection circuit includes a number of two-way switches (A,B,C,D) each of which has a terminal (0) which may be connected to one of two other terminals (R,T). In their rest state the switches are in the position connecting to O and T, and they are connected in series using these terminals. The series line is connected atone end to earth, and at the other end to a processing unit (10). The two terminals (R,T) of each switch are in fact connected together so that when a switch changes, the circuit is interrupted only for the time taken for the mobile switch contact to move. The temporary break in the circuit may be detected by the processing unit (10), but immediately after the incident the unit is reset and able to detect any subsequent interruption. The switches may be arranged to detect unauthorised entry to a building.

Patent FR-2473419-A1 (FR)
Inventor: SMITH THOMAS L
IPC: D06M17/00
Filed: 1981-01-12
Abstract: A laminate or a laminated article with integrated raised zones having the appearance of buttons, borders, surrounds, folds or the like is specified. A process for producing such a laminated article is also specified. The laminated article consists of a textile or vinyl synthetic resin cover layer, a foam intermediate layer and a layer of substrate material, for example a polyamide. A shaped article having the desired shape for the raised zone is inserted between the foam layer and the cover material layer. Anhydric polyurethane foam-forming materials are applied in liquid form onto the foam layer, the contact surface of the cover material and the contact surface of the substrate material. Before the lamination, the layers are placed on a mould, the shaped articles being arranged directly above those mould projections which follow the contours of the mould projections. Moisture is introduced into the foamable material and a heated press is caused to act on the substrate material, the layers lying one above the other being pressed downwards against the mould. The press force with simultaneous heat supply causes a foaming reaction of the foamable material, leading to a foam adhesive layer which substantially adhesively bonds the cover material to the substrate material in the zone surrounding the shaped articles. The binder layer also bonds the cover material and the substrate material to the other surfaces of the foam layer.

Title: Flexible membrane contact key-pad with air permeable substrate - has space under each key ventilated through holes in lower contact plate and fibre layer on supporting base preventing contamination
Inventor: KAMADA EIICHI
IPC: H01H13/702

The device provides a sealed keypad in which the performance does not depend on the outside air pressure.
Patent FR-2489940-A1 (FR)
Inventor: FORSTER HANS
IPC: F25B30/04
Filed: 1981-06-25
Abstract: The invention relates to a process for useful heat production from waste heat with the aid of a sorption process, in which the useful heat has a considerably higher temperature level than the waste heat (heat step-up). At the same time, the process can be combined with an absorption refrigerating part, with variable portions of both part installations. The aim of the invention is the economical utilisation of any waste heat arising, even that with a low temperature level, and its conversion or upgrading to useful heat. The essential part of the invention is to design the heat step-up in one or more stages in such a manner that the useful heat output or yield lies close to the theoretically possible value and the waste heat carrier is cooled to close to the ambient temperature. In this connection, it is possible by using regenerative heating systems and a consistent countercurrent guidance during absorption, desorption and heat transmission, to bring about a great temperature interval between useful heat and available waste heat. The invention can be used for thermal processes, in which waste heat with a low temperature level arises and there is a requirement for useful heat at 100 to 250 DEG C.

Title: Method of growing rice under irrigation - with specified land treatment and feeding regimen to increase yield
Inventor: ALESHIN E P
IPC: A01G22/22
Filed: 1981-12-15
Abstract: Method of growing rice comprises ploughing, harrowing and levelling the soil after autumn tilling; applying a pre-plant herbicide; dressing the seed with fungicide and growth promoter; sowing the seed; adjusting the water level according to the growth of the rice plants; protecting the crop against weeds, pests and diseases by "agrotechnical" and chemical treatment; gradually draining the field as the rice grain begins to mature; and harvesting the rice. The improvement comprises (a) subsoiling the field transverse to the previous ploughing direction prior to harrowing; (b) levelling the field and excavating a system of pipeless drains before applying the pre-plant herbicide; (c) applying most (80-85%) of the total N fertiliser and all of the P fertiliser at the same time as sowing; (d) pumping water into the field at a rate of 30-50 l/ha.sec. when the seedlings have emerged; (e) applying the rest (15-20%) of the N fertiliser at the 2- to 3-leaf stage; (f) applying all of the K fertiliser at the 6- to 8-leaf stage; (g) spraying the plants at the start of the waxy grain stage with 150-200 l/ha. of an N or P feed contg. 15-20 ml/ha of a 2,4-D amine salt; and (h) cutting swaths around and across the field after draining and before harvesting. The process is stated to increase yields by a factor of 2-3, to reduce water consumption by 5-10% and to reduce the delay in sowing by 5 days. Exemplified yields are 6.0 and 6.2 t/ha.

Title: Liquid-filled protective electronic equipment housing - balances hydrostatic pressure by immersing electrical components in box filled with incompressible dielectric liquid
IPC: B63B3/13
Filed: 1982-04-21
Abstract: The invention is designed to protect electrical or electronic circuitry in conditions of high external fluid pressure, for example in undersea equipment. The principle is to totally immerse the circuitry in a dielectric liquid which, being incompressible, is able to balance external pressure without change in volume. A rigid box has openings to allow access to the circuit elements, two sealed holes for the input and output electrical cables, valves for filling and emptying the container, and an opening over which a rigid membrane (5) is placed. The membrane transmits external pressure to the interior, whilst maintaining a physical barrier between the external and internal ambients. The pressure in the interior may be held slightly in excess of the external pressure so that any pressure differential will result in an outward flow of dielectric liquid rather than an ingress of the external ambient. The membrane can be tensioned by an arrangement in which a spring (10) bears against a stirrup (8) fixed to the wall and presses on the membrane.
