Title: Commutators
Inventor: DAWSON JOHN
IPC: H01R43/06
Filed: 1985-07-22
Abstract: A method of construction of a commutator in which a tubular support member (1) is formed from a stack of laminations, the support member (1) having a number of axial grooves (3) running along its external periphery. Respective pairs of conductive segments (5, 7) are placed in each of the number of folds of a flexible insulating material (9), one fold then being placed in each groove (3). Respective flexible wedge members (11) are then inserted between each pair of segments (5, 7) to secure the fold and segments (5, 7) within each groove (3). The whole assembly so formed is then subjected to a vacuum pressure impregnation process and the completed commutator finish machined in the normal way. <IMAGE>

Patent GB-2187668-A (GB)
Title: A hand operated riveting tool
Inventor: CLARK ROBERT NIGEL WAKE
IPC: B21J15/04
Filed: 1986-03-07
Abstract: The riveting tool has two pin drawing arms (l0 and ll) and a pin clamping arm (l2). Springs (20, 28) act between the arms to urge them apart. When the arms (ll) are drawn together, the arm (l2) firstly moves towards the arm (ll) because spring (28) is weaker than spring (20). A cam formation (29) on the arm (l2) bears against a cam follower (26) on a slider (22) and the slider moves to clamp a clinching pin between clamping members (24 and 25). The arm (ll) then moves towards the arm (l0) to open elongate jaws (l7, l8) and draw the clinching pin at least partly through a rivet.

Title: Tractor-less feed of fan-fold computer stationery
Inventor: WELLS JOHN DAVID
IPC: B65H20/00
Filed: 1986-04-01
Abstract: This invention relates to a tractor-less drive for computer fan-fold (CFF) web being fed to a reprographic or like machine. When in the CFF-feed mode, travel of the web is monitored by two sensors 26, 36 aligned with the holes along one web border. Both sensors generate hole-transition pulses and, in conjunction with timers, the pulses are compared end timed to detect torn and blocked holes, and slippage or stalling of the web feed. The comparison leads to the feed being continued or stopped. <IMAGE>

Title: A process for treating fibrous cellulosic webs and liquids for use therein
Inventor: HOLMSTEDT JAN WALTER
IPC: D06M11/79
Filed: 1988-11-25
Abstract: The invention provides a method of treating fibrous cellulosic web for manufacture of corrugated or laminated sheets, tubes (10, 20) or other elements suitable for use in the building industry or for packing. The web (5) of material passes continuously through 3 separate chambers (1, 2, 3) before entering forming apparatus. The first chamber (1) contains a liquid for breaking down the fibres of the web (5); the second chamber (2) contains a liquid for impregnating the fibrous cellulosic web; and the third chamber (3) contains a liquid for enhancing the elasticity of the impregnated fibrous cellulosic web and for reducing the drying time of the web (5). During the forming of a corrugated product, a glue comprising an alkali metal silicate solution, an acetone solution and a hardener e.g. triacetin is used. The sheets (10) or tubes (20) or other elements formed in the forming process are then sprayed with a liquid for enhancing the resistance to water of the fibrous cellulosic web. The liquids can be used advantageously in other processes.
Patent GB-883109-A (GB)
Abstract: 883,109. Electric selective signalling systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 1, 1959 [May 1, 1958], No. 13882/58. Class 40 (1). In an arrangement, Fig. 1, in which a coded scale 9 is caused to " follow " an input voltage V by means of a potentiometer 3 which is driven to such a position by a motor 6 as to balance the input voltage, an attempt to compensate for mechanical inertia or " lag " in the position of the coded scale relative to the instantaneous value of the input voltage is made by rotating the sensing brushes of the coded scale an amount proportional to the magnitude of the out-ofbalance signal, by a torque motor 12 and spring 14. Thus when there is a large out-of-balance signal-which means that the position of the coded scale does not correspond exactly with the input voltage-the sensing brushes are rotated in a direction to compensate for this, and when the out-of-balance signal is zero the sensing brushes return to their normal position. A modification (Fig. 3, not shown) is described using a linear, as opposed to circular, potentiometer and coded scale. The coded scale can be of the type described in Specifications 762,284 and 808,564 which are referred to.

Title: A method and apparatus for assembling a vehicular driving shaft
Inventor: KAMATA YOSHIHARU
IPC: B23P19/08
Filed: 1989-03-13
Abstract: A driving shaft moves along an assembly line with its longitudinal axis vertical and component parts of joint units e.g. a bell type or tripod constant velocity joint unit or the like are attached to each of both ends of the driving shaft e.g. from below as the driving shaft is sent to each of a plurality of assembling stations. The respective joint units to be attached to each of both ends of the driving shaft are assembled one at a time. A first joint unit is assembled from below to the lower end of the driving shaft at a first group of assembling stations of the assembly line. Then, the driving shaft is inverted at a reversing station of the assembly line and a second joint unit is assembled from below to the lower end of the driving shaft at a second group of assembling stations of the assembly line. The vertical orientation of the driving shaft reduces the amount of planar space required from below means that no parts can fall into the driving shaft assembly, requiring time consuming and difficult removal. …<??>The assembly line may comprise an annular conveying passage provided with a plurality of carriers holding the drive shaft in its vertical posture, and with the discharging station situated next to the charging station on the assembly line the efficiency of assembly is improved.

Patent GB-2239192-A (GB)
Title: Filter bed
Inventor: SEYMOUR EDWARD ANDREW
IPC: B01D24/12
Filed: 1989-12-19
Abstract: A liquid treatment tank (1) with a liquid inlet (2) contains a layer of components (4) having buoyancy in the liquid. During treatment the liquid is directed so that it premeates through the layer. During treatment the layer is stabilised by restricting the buoyancy of the layer in the liquid. This may be done by maintaining the level of the liquid below the surface of the layer with the outlet stand pipe (7). The layer filters the liquid of particles alone, or together with soluble material. When the apparatus is to be serviced for removal of particles from the layer the buoyancy of the layer is released. This provides for loosening of the components and the particles can be freed from the interstitial spaces of the layer. The particles are released to a position below the layer and may be discharged from the tank. The invention can for example be applied to the mechanical and biological filtration of impurities from waste water.

Title: Process for food analysis
Inventor: DEASY DONAL JOSEPH
IPC: G01N33/02
Filed: 1990-10-30
Abstract: In a process for the analysis of discrete food samples (3) presented to an analysis instrument (2), bar codes on the samples are read by a bar code reader (5) to ensure traceability of all samples. A control unit (10) captures analysis data from the instrument (2) and determines if the analysis data is from an active sample such as that from a milk supplier or a standard sample used for calibration of the instrument (2). If the sample is a standard sample, the control unit (10) outputs on a trace recorder (14) and a VDU (15) calibration deviations so that calibration of the instrument (2) may be monitored on an on-going basis during analysis of a batch of samples (3). If a calibration deviation is excessive the control unit (10) switches off the instrument (2) to avoid the need for re-work and the risk of wrong analysis data being generated. Further, the control unit (10) compares the analysis data of active samples with historical data such as that for previous milk supplied by a particular supplier. A message is displayed at the VDU (15) if the difference is outside of a tolerance range. <IMAGE>
