Title: Load determination by Brinell ball technique - computes max. load in given period using reference disc of known hardness
IPC: G01L1/06
Filed: 1973-11-30
Abstract: The method of measuring the maximum load experienced by an element during a given time period is based on the Brinell ball technique. The load to be measured is applied to a Brinell ball of known diameter, acting on a disc of known hardness during the given period. The diameter of the indentation made on the disc is then measured and from this the maximum value of the force having acted on the ball during the measurement period is calculated, this force being equal to the load to be determined. The apparatus for operating this technique comprises a Brinell ball (10), a support (6) and a jacket (7), the support holding the ball (10) by means of a clamp (11) and the jacket holding a metallic disc (13) of known Brinell hardness and adjusted so as to slide within a recess (14) made in the jacket (7). The disc (13) is held by a clamp (15) fixed to the jacket.

Title: Joint for tubular filter cartridge face pieces - partic. useful for motor oil and fuel filters
IPC: B01D29/21
Filed: 1974-02-01
Abstract: A catch, for joining the face pieces of a filter cartridge, of the type in which a tubular filling of filter material is held between two face pieces with central holes, consists of two parts. The first part incorporates a ring on the end of a support made of radial ribs fixed around the hole in one face piece. The second part consists of flexible hooks, facing inwards, fixed on a base around the hole in the other face piece. When the ring is pushed between the hooks, they are elastically deformed outwards, engaging with the surface of the ring. In a second form, the support piece of the first part is made of tongues, fixed around the central hole, and the hooks of the second part face outwards, so that the ring deforms them inwards and engages with them, when it is pushed over them. In other forms, the second part is a split disc with sloping edges on a split steam, or a split ball, and the ring is pushed over the disc or ball. Used partic for filters for oil or fuel for IC engines, in which the filter element is made of paper or textile impregnated with polymerised resin, folded and/or chevronned to give a tubular shape with some elasticity and fixed to the end pieces by an adhesive. Assembly is much simpler than it is in the case of existing filters, which have a rigid, perforated tubular armature joining the end pieces and require positioning and joining by e.g. soldering.

Title: Programmable fixed store using emitter coupled logic - has data stored in form of burned out resistors in transistor collector circuits
IPC: G11C17/16
Filed: 1974-02-15
Abstract: The store consists of a number of matrices of npn transistors arranged in rows and columns, with a transistor at each "data point" in a matrix. A particular data point, or transistor is assessed by driving a current down the appropirate row and column conductors, the row conductors being attached to the emitters of a row of transistors, whilst the column conductors are attached to the bases of a column of transistors. The collector of each transistor is connected via a resistance to a suitable current and voltage supply. To write a "one" into a particular location the appropriate row and column are chosen and a current is driven through the collector resistance sufficient to melt and open circuit it.

Title: Colouring rubber substrates - by coating the clean polymer surface with a halogenated polyolefin prior to colouration
IPC: C08J7/043
Filed: 1974-02-15
Abstract: The cleaned polymer surface is coated with >=1 layers of a halogenated polyolefin, pref. a chlorinated polyolefin of MW 5,000-15,000 in soln. in an org. solvent, and coating of the desired colour is then applied, pref. in the form of a pigmented polyurethane in an org. solvent or a mixt. thereof with a polyester or a polyether. This enables the final props. of the colour layer to be varied, e.g., high flexibility for thin sheets of substrates, hardness and low flexibility where high rub-resistance is required. Adhesion between the various layers is good and the process is esp. applicable to the mfr. of rubber components used in the car industry.

Title: Shade for light fittings - consists of crossed strips whose crossings are masked by decorative star shaped connectors
IPC: E04B9/00
Filed: 1974-03-19
Abstract: The shade is used for covering ceiling mounted lighting fittings from direct view.

Title: Poultry drinker with automatic supply - has receptacle and cover and inlet control float
IPC: A01K39/024
Filed: 1974-03-29
Abstract: A receptacle has a plastic cover with communicating holes in its base and radial lugs with notches into which a peripheral flange of the receptacle is press fitted.

Title: Spectacle side spring hinge - eye in longitudinal direction of side moves in guide against spring
IPC: G02C5/22
Filed: 1974-06-13
Abstract: The end sections of the flat U-shaped guide are at an angle to each other. The hinge eye is located on a sliding member with an approximately T-shaped cross-section which moves in the guide. An undulated, preshaped plate spring between the base of the guide and the sliding member, is made of stainless steel and by positioning it in the guide, free play of the side round the longitudinal direction is prevented. This also applies to relatively course tolerances during the manufacture of the hinge sections which engages. A certain movement of the side has first to overcome the spring force.

Title: Selective magnetic separation - of weakly magnetisable minerals involves magnets with superconducting coils
IPC: B03C1/0355
Filed: 1974-12-04
Abstract: Selective magnetic sepn. of weakly magnetisable matls., e.g. rare minerals , is achieved by passing suitably pretreated matl. (ground, dried, sieved, etc.) to the magnet separator where magnetisable components exceeding a threshold in magnetisability are deflected to be discharged into special containers while the remaining matl. passes through the field to other receptacles. To increase field strength, the magnetic field is generated in the air gap between superconducting coils. The force acting on the matl. is increased by spatial configuration and electrical connection of several coils into multi-polar arrangements to achieve field inhomogenisation with formation of field gradient. Local force effiency is further increased by super-imposing a practically homogeneous magnetic field on the multipolar fields.
