Patent GB-2078166-A (GB)
Title: Composite sheets
IPC: B32B27/04
Filed: 1980-06-16
Abstract: Composite sheet material is built-up of a plurality of single plates joined together by means of one or more interposed biadhesive tapes. The composite sheet may be provided with a coloured or reflecting film and may comprise in addition inserts formed of films or wires provided for increasing the strength of the sheet or for serving as part of electric heating or alarm circuits. The process for making the sheets provides for the application of the biadhesive tapes without the forming of air pockets and for a compression effect acting over the whole surface of the composite sheet within an autoclave. The single plates forming the sheet may be of glass, polycarbonate, or other synthetic material. The biadhesive tape is preferably provided on both sides with a protective film, to be removed before the application of the tape and the adhesive securement together of the single plates.

Title: Metering system for dispensing beer or other potable carbonated liquids
IPC: G01F11/08
Filed: 1980-06-25
Abstract: Beer is dispensed in metered quantities from a keg 14 through an outlet 9 under the control of a dispensing valve 10 by a membrane metering pump 1. The valve 10 and a gas inlet valve 18, which supplies gas to the pump 1, are controlled by an electrical controller 22, a dispensing operation between triggered by closing a press button switch 24. The controller 22 is also actuated by a reed switch 26, which is controlled by a magnetic closure member 27 of an inlet non-return valve 12 and the reed switch 26 and the controller 22 control the valves in such a way that after a measured volume of beer or other liquid has been dispensed from the compartment 4 of the pump 1 and the compartment 4 has been refilled with beer, the valve 18 is opened whilst the dispensing valve 10 remains closed so that the beer in the compartment 4 and in the ducts leading from the compartment 4 to the valve 10 is maintained under the pressure of the gas supplied through the valve 18. <IMAGE>

Title: Batch washing machine
IPC: D06F31/00
Filed: 1980-06-26
Abstract: In a batch washing machine comprising a tubular washing drum with a helically coiled wall member extending along the inside of the drum to act as a screw conveyor and at the same time to form successive washing chambers for the batches of laundry, the said wall comprises successive wall portions 5a, 5b, with stepwise transitions. Thus the wall acts like a washboard and improves the mechanical contribution to the washing effect due to reciprocating rotary movement of the wall about the axis of the drum. Conveniently, the wall consists of triangular wall portions 5a, 5b arranged as shown in the drawing, preferably about 12 pairs of wall portions to one helical turn of the wall. The wall can readily be made up of halfturns welded together, the triangular wall portions being preferably so shaped as to provide a common side edge 6 of each pair of adjacently disposed portions which extends radially with respect to the axis of rotation. <IMAGE>

Title: Fluid actuator
IPC: F15B15/14
Filed: 1980-07-03
Abstract: A fluid actuator basically consists of a tube with a circular bore, a ball 4 in the bore acting as a piston and an O-ring 3 in the bore which acts as a seal between the bore and a confronting annular portion of the ball. The main advantage is simplicity of construction, for example, for readily available parts. Other arrangements include a tube with two balls and an O-ring therebetween, the tube having inlets to admit fluid pulses which cause the balls to oscillate; and a cylindrical body with transverse bores each containing a ball and an O-ring, a common inlet enabling fluid pressure to act on the balls so that they protrude from the body to engage a workpiece. <IMAGE>

Title: Data processing system having memory modules with distributed address information
IPC: G06F12/06
Filed: 1980-10-07
Abstract: A plurality of modules are distinguished from each other by high-order memory address bits while locations in each memory module are addressed by low-order memory address bits. Each of the memory modules includes a memory identifier means for storing a high- order identifier address and a comparator means for comparing the high-order address bits of an address applied to all modules with the identifier address. If they match, an identifier signal is provided enabling the memory module to be addressed with the low-order address bits. All memory modules which do not have a match between the identifier address and the high-order memory address are not enabled.   Different numbers of high and low order bits may be used in different modules depending on their storage capacity. The numbers used are set in each module by a switch. The enabling identifier signal lines of all modules are connected to provide a signal indicating that one module has responded to a high order address.

Title: Gearwheel pumps
IPC: F04C11/00
Filed: 1981-10-28
Abstract: A plurality of pairs of externally-meshing pumping gears 1a, 1c are driven by a central common gear-wheel, or "sun wheel", 9.

Title: Beta-alumina electrolyte material
Inventor: LAU JOHN WING-KEUNG
IPC: C04B35/113

Title: Latch with backset adjustment
Inventor: GATER ARNOLD C
IPC: E05B63/06
Filed: 1982-02-18
Abstract: A bolt 24 is conventionally reciprocal in a stationary casing 26 with each being formed of longitudinally telescoped parts and with the parts of each being bayonet joint connected. Each bayonet joint connection is comprised of a projection of one part selectively movable in a pair of longitudinally spaced, transverse slots separated by a longitudinal slot in the other part, whereby each may be selectively longitudinally adjusted the same determined amount for increasing or decreasing the backset distance between the forward extremities of the casing and the latch operator 22 transverse axis the same determined amount. The transverse cross sections of certain slidably reciprocal mating parts of the bolt and casing are formed generally mutually rectangular so that rotational movements of one during the backset adjustment will positively require the same rotational movements of the other. A spring- pressed friction member between the casing telescoped parts frictionally resists movement therebetween minimizing any danger of non- planned, accidental backset adjustment. <IMAGE>
Patent GB-2096352-A (GB)
Title: Fluorescence spectroscopy
IPC: G01N21/64
Filed: 1982-03-26
Abstract: A method for conducting fluorescent spectroscopy which involves irradiating a test sample with light of a first wavelength which causes the test sample to fluoresce light of a second wavelength and measuring a portion of the fluorescent light; irradiating the test sample with light of the first wavelength at reduced intensity and measuring the light of the first wavelength transmitted through the test sample; and comparing the intensity of the fluorescent light to the transmitted light. The invention also includes apparatus for carrying out the above method. In such apparatus, an improved filter assembly is rotatable between a test position and a reference position. The filter assembly includes a pair of test filters, one passing excitation light at one wavelength and the other passing fluorescent light from a test solution at a second wavelength, a pair of reference filters, each passing light at the first wavelength, and light shielding means to block stray light and prevent it from optically coupling between the filters. A pre-filter minimizes the background transmitted light. Insertion of the filter assembly into a commercially available automated clinical photometer enables the instrument to be used as a filter fluorimeter.

Title: Preparation of N-(dihalobenzyl)-N-alkyl-2,6-dinitro-4-trifluoromethylanilines
Inventor: OLIVER WARD HOPKINS
Filed: 1982-10-09
Abstract: A process for the preparation of N-(dihalobenzyl)-N-alkyl-2,6-dinitro-4-trifluoromethylanilines involves the reductive amination to form the N-alkyl-dihalobenzylamine intermediate by converting the appropriate di-halo-benzaldehyde to its Schiff's base in the presence of an alkanol and the required monoamine while adding an alkali borohydride. The N-alkyl-dihalobenzylamine is obtained in good purity at high yield. It is then reacted with 4-chloro-3,5-dinitrobenzotrifluoride in a two-phase solvent system and in the presence of alkali to form the desired agriculturally active final compound.
