Title: Method of applying coatings
Inventor: THIRLWALL ERNEST
IPC: B05D5/00
Filed: 1981-09-10
Abstract: A method of applying a coating to a surface consists of applying to the surface a base film of a urethane composition having a thickness of 1-2 mm, allowing the applied film partial cure, applying an inert mineral aggregate having a particle size of 1-4 mm to the coated surface by sprinkling the aggregate densely over the surface, allowing the base coating to set, removing excess aggregate and then applying a thin coat of the base material to seal in the aggregate.

Title: Monitoring battery charging
Inventor: NUDDS DERRICK ALFRED
IPC: G01R31/36
Filed: 1981-10-02
Abstract: A circuit for monitoring the charging of a bank B1, B2 of battery cells having a centre tap X includes two potential dividers VR1, VR2 connectible across the bank and two differential amplifiers A, B each having one input 2, 4 connected to the centre tap X and the other input 1, 3 connected to the slider of a respective one of the potential dividers VR1, VR2 the outputs of the amplifiers A, B being connected in parallel to supply current to a fault indicating circuit LED1, LED2, TR1, the arrangement being such that when the sliders of the two potential dividers VR1, VR2 have been adjusted to supply sufficient current to the indicating circuit any variation of the potential of the centre tap in either direction relative to the ends of the bank, eg. due to a cell going abnormally high or low in resistance, will cause the current through the indicating circuit to fall thus indicating the fault. In the event of a fault, transistor TR1 turns off and relay RL1 drops out to signal the fault and/or cause charging to be stopped. <IMAGE>

Title: Improvements relating to hepatitis B vaccine
IPC: A61K39/29
Filed: 1982-01-21
Abstract: Immunogenically active fragments of hepatitis B surface antigen, which are a glycoprotein of molecular weight about 28,000 (gp 28) and a protein of molecular weight about 23,000 (p 23), obtained by known methods by treatment of surface antigen with detergent, are prepared in micelles form substantially free from detergent. The micelles are at least as immunogenic as the unfragmented antigen from which they are derived and are useful in the preparation of hepatitis B vaccine. The detergent is removed by layering the detergent containing fragmentation product on an aqueous buffer containing a sucrose gradient and centrifuging the layered buffer when micelles containing both gp 28 and p 23 form and can be recovered in substantially detergent free form from the centrifuged layered buffer.

Title: Drive axle suspension for commercial vehicles
Inventor: MANNING WALTER
IPC: B60K5/00
Filed: 1982-08-03
Abstract: This invention makes possible the close coupling of the transmission assembly output and the drive axle assembly input of a power train comprising all or any combination of power unit, cooling system, clutch, fluid coupling, torque converter, transmission assembly, drive line retarder, transmission to drive axle coupling and drive axle assembly by mounting the selected power train to a swinging arm assembly. Overall package dimensions of any type of power train combination may then be reduced giving greater choice to the engineer in designing for vehicle axle locations and weight distribution. Vehicle handling and ride features are retained by arranging a suitable hinge point location coupling the swinging arm assembly to the body or chassis assembly to optimise suspension geometry and unsprung inertia. The selected suspension system is fastened to the drive axle assembly of the drive axle end of the swinging arm assembly. When compared with vehicles currently operating with power units installed at the rear end or amidships a considerable saving in parts count and complexity can be achieved. <IMAGE>

Title: Coin collecting mechanisms
Inventor: DAVIES GERAINT WYN
IPC: G07F9/04
Filed: 1983-06-15
Abstract: A coin collecting mechanism, particularly a coin collecting telephone box of the kind having a coin entry slot (3) and a coin refund aperture closed by a refund flap (5), has the refund flap (5) linked to a shutter plate (8) which is arranged to close the coin entry slot (3) if the refund flap (5) is opened. This prevents fraudulent acquisition of refunded coins by persons jamming open the refund flap (8) thereby preventing the passage of coins from within the mechanism to the refund aperture. In case a jamming object (e.g. a screwdriver) is inserted through the coin entry slot (3) prior to opening the refund flap (5) the shutter plate (8) is linked to an operating member (6) (which is connected to the refund flap (5)) by a spigot (10) which runs in a slot (11) in the operating member. When the jamming object is removed from the coin entry slot (3) the shutter plate (8) moves to obstruct the slot (3) under the influence of a spring arrangement (12). <IMAGE>

Title: Method and apparatus for spectroscopic analysis
Inventor: HAMMER MICHAEL RON
IPC: G06F17/00
Filed: 1984-11-21
Abstract: A method of analyzing an atomized sample 3 by the use of a spectrophotometer having an electronic detector 5 which is operative to generate a signal which is representative of a characteristic of the sample 3 includes continuously sampling the aforementioned signal and periodically computing both an estimate of the mean value of that signal and a factor representative of the standard deviation of the mean value estimate computed at that time. In addition, the mean value estimates and relevant standard deviation factors are automatically related to one another as they are computed and are also related to the number of estimate computations completed at the relevant time, and that relationship is utilized to automatically determine the level of precision in each mean value estimate. A suitably programmed micro-processor 6 coupled to the spectrophotometer can be used for the foregoing sampling and computations. A control 7 and timer 8 are provided whereby the sample analysis is automatically terminated when either a predetermined level of precision is reached or a predetermined time period has expired. <IMAGE>
