Patent GB-2014437-A (GB)
Title: Improvements relating to vacuum cleaner nozzles
IPC: A47L9/02
Filed: 1978-12-14
Abstract: Vacuum cleaner nozzles have to pick up threads from carpets, and to loosen these threads from the pile the nozzles generally have means that will perform a raking or stripping action as the nozzle is moved to and fro. To improve this, there is proposed a flexible pickup strip (12) housed in a downwardly divergent recess (6, 7) in the underside of the nozzle (2). As the nozzle is moved the strip is wiped over the pile, which springs up into the recess and engages a brushed velour (for example) covering over at least the lower edge portion of the strip. The strip flexes towards whichever of the inclined walls (8, 9) of the recess is trailing. <IMAGE>

Patent GB-2038241-A (GB)
Title: Relief decoration of flexible substrates
IPC: D06N3/08
Filed: 1978-12-21
Abstract: Decorative flexible goods such as vinyl floor and wall coverings wherein a simulated embossed pattern is created in register with a printed-design by means of printing a coating which is essentially solvent-free and comprises at least one organic compound having at least two photopolymerizable ethylenically unsaturated groups per molecule and capable of curing upon exposure to actinic radiation. The actinic radiation cured coating serves the purpose of creating the desired relief to the pattern in register and also forms a durable wear layer with superior stain and wear characteristics as well as gloss retention properties. The relief is generally a surface crinkle or distortion resulting from differential properties of the coating and substrate. The flexible goods substrate may be non-cellular or it may be a cellular substate with a clear resinous overlay.

Title: Motor control circuit
IPC: H02P7/06
Filed: 1979-06-15
Abstract: A control circuit for a series motor 10 of a food mixer utilizes a speed control device 30, e.g. a centrifugal governor having contacts 32, connected in the triggering circuit of a triac switch 20 for selectively connecting the motor 10 to power source terminals 16, 18. The contacts of the governor open and close as the rotational speed of the motor increases and decreases respectively from a predetermined speed as set by control 50. An impedance element 82, 84 in the triac triggering circuit provides a minimum conduction angle of the triac independent of the motor speed for each half-cycle of the power source waveform and when the governor switch contacts are open. The system achieves smooth, stable motor control, reducing low speed instability problems i.e. cogging. <IMAGE>

Title: Belt clamps for vehicle passenger restraint belts
IPC: B60R22/42
Filed: 1980-01-22
Abstract: A belt clamp for use in a vehicle passenger restraint belt system comprises a pair of jaws, one of which 220 is movable relative to the other 216, as by a lever 222, is normally held away from the other by a spring 226, and is moved toward the other in response to an abnormally high pull-out force to engage a restraint belt 210 guided between the jaws. A multiplicity of spaced-apart, elongated straight teeth 104 oriented widthwise of the belt and of uniform, smoothly curved cross section frictionally clamp the belt against pulling out by tucking loops of the belt into complementary recesses 106 in the other jaw. Preferably, both jaws have substantially identical teeth and recesses to. Advantageously, small variations in gripping faces of the jaws compensate for variations in the properties of the belt (e.g. thickness, density and elasticity) and for deformation of the jaws. <IMAGE>

Title: Bi-stable inertia switch
IPC: H01H29/00
Filed: 1980-02-12
Abstract: Apparatus for indicating that an acceleration greater than a predetermined acceleration has occurred; has a housing 41 with a liquid reservoir 47 and an adjacent gas region 43 having contacts 49, 51 therein; the liquid gas interface resisting deformation by interfacial tension, the arrangement of electrical contacts 49, 51 in the gas reservoir and the liquid reservoir being such that the liquid has at least a portion moved to establish electrical continuity between the electrical contacts upon the occurrence of a predetermined acceleration. The structure and arrangement of the contacts and gas and liquid reservoirs are such that a greater negative acceleration is necessary to restore the shock-switch to its "off" condition after it is moved to its "on" condition. The switch is, however, resettable by imparting a negative acceleration of sufficient magnitude. The switch may also be operated by lateral accelerations. <IMAGE>

The nature of the cartridge 10 permits the apparatus to be made more compact and reduces the risk of contamination or air-ingress. <IMAGE>
Patent GB-2048781-A (GB)
Title: Emulsion lighographic printing system
IPC: B41F31/02
Filed: 1979-12-05
Abstract: Water and oil base ink are delivered to lithographic plates as a single liquid (21), a mixture of water and ink, wherein the water is in the form of fine droplets. Preferably also, lithographic concentrate is added to the mixture as part of the water content. During a printing run the mixture (21) is automatically resupplied to the printing machine by a level sensor (43) that controls the amount of ink and water and by a pH sensor (42) that controls the concentrate percentage. The proportion of ink and water is controlled by a moisture sensor (41). The thickness of the film of mixture delivered to the lithographic plate is controlled by a density sensor (46). A viscosity sensor (44) controls the agitation of the mixture. A set of three rollers (34, 37, 39) is used to deliver the ink-water-concentrate mixture to the lithographic plate (38) in contrast to several dozen rollers conventionally used. The rollers (112) that supply ink and/or water to form rollers (113) have a surface with minutely intermixed hydrophilic and oleophilic areas (140, 141, 151, 152, 161, 162). The amount of water retained by a roller is dependent upon the total of the hydrophilic areas (e.g. 140), and the amount of oil-based ink retained by the roller is dependent upon the total of the oleophilic areas (e.g. 141). A preselected ratio of oil to water is obtained by selecting the ratio of hydrophilic areas (e.g. 140) to oleophilic areas (e.g. 141)
