Title: A manual operator for an electric switch
IPC: H01H23/24
Filed: 1968-12-12
Abstract: 1,254,460. Snap-action switches. LA TELEMECANIQUE ELECTRIQUE. 12 Dec., 1968 [15 Dec., 1967], No. 59250/68. Heading H1N. A rocker-operated switch comprises a hollow rocker 5 provided with a central window 24 through which are visible alternately indicia or inscriptions A and B on a pivoted member 4 having two stable switch-operating positions, the member 4 operating a snap-action switch (not shown) via rods 7A, 7B. A lamp (not   shown) may illuminate the indicia A, B. Member 4 may be constructed to have more than two stable positions and corresponding indicia. A spring-pressed ball 15 co-operates with a spur 14<SP>1</SP> on pivoted member 4 to define the two stable positions.

Title: Heat-sensitive device
IPC: A47J37/08
Filed: 1972-12-27
Abstract: 1424684 Thermal switches MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 27 Dec 1972 [29 Dec 1971] 59628/72 Heading H1N [Also in Division A4] A heat-sensitive device comprises an electric heating wire 56, a metal block 54 and a bimetal strip 47 thermally connected in series in that order, the heater wire 56 being directly mounted between a pair of terminal plates 57, 58, strip 47 performing a switching operation as a result of heating or cooling of the device The idea is that the metal block 54 provides a time delay on heating. A toaster embodying the invention is described below. To start toasting, bread seat holder 19 carrying bread seat 21 is pushed down by handle 22 until locked down by lock 42a and holder 19 also pulls down slide 28 by spring 30 till protuberance 33 in slide 28 engages projection 41 and contacts 38, 39 are closed (Fig. 9b, not shown) to energize toasting element 14 and bimetal heating wire 56. Bimetal 47 heats up and after a time delay contact 49 engages contact 40 to energize electromagnet 26 to free protuberance 33 from projection 41 by electromagnet 26 attracting iron piece 31 to pivot slide 28 about pin 27. When freed, slide 28 is pulled down further by spring 30 until protuberance 32 engages projection 41 (Fig. 9c, not shown). Slide 28 moving down changes over contact 38 to contact 40 and changes over contact 35 to contact 36. Toasting continues but heater 56 is de-energized so that bimetal 47 cools down and changes over contact 49 to contact 51 so that electromagnet 26 is again energized. This releases protuberance 32 from projection 41 as before and slide 28 is pulled down further to the bottom of its travel by spring 30. Thus iron piece 31 on slide 28 engages hook 42 to pivot it and release holder 19, Fig. 9d (not shown), to allow holder 19 to be pulled up by spring 20, holder 19 pulling up slide 28 by spring 30 thus opening contact 38 and stopping the toasting. The toast colour adjustment is by knob 52<SP>1</SP> adjusting a cam 53, Fig. 5 (not shown), engaging screw 52, Fig. 5, engaging the support plate carrying contact 51.

Title: Pneumatic tyres
IPC: B60C15/00
Filed: 1970-12-22
Abstract: 1328666 Pneumatic tyres MICHELIN & CIE (COMPAGNIE GENERALE DES ETABS MICHELIN) 22 Dec 1970 [23 Dec 1969] 60928/70 Heading B7C A radial ply carcass pneumatic tyre 10 has one or more plies of cords 12, 13, 14 defining the carcass, the end portions 23, 24, 25 of which plies extend round the bead wires 15 and back to form returned portions, the, or at least the longest of the returned portions in each bead region extending back from the bead wire in an undulating path including at least one concave undulation, in which the axial distance between the returned portion and the carcass cords decreases and then increases from the bead wire to the end of the returned portion, whereby said returned portions do not substantially stiffen the sidewalls in the radial direction. The, undulating path is achieved by placing during the manufacture of the tyre a number of shaped portions of elastomer 33, 34 respectively between the carcass plies and their returned portions, and between the latter and a stiffener 31 which is positioned inside the tyre to reinforce the region which rubs on the rim of a wheel on which the tyre is mounted in use. The point at which the returned portion is nearest to the inner surface of the sidewall its substantially the midpoint of the returned portion. The end of the or at least the longest returned portion in each sidewall and the point at which that returned portion is nearest to the inner surface of the adjacent sidewall are respectively radially outwards and radially inwards of that level of the bead region which bears against the radially outermost part of the wheel rim flange when the tyre is fitted to a wheel and flexed. The distance, measured axially of the tyre, between the end of the returned portion and the portion of that ply defining the carcass is at least the diameter, or greatest cross sectional dimension of the bead wire. The carcass cords may consist of steel, rayon, polyamide or polyester.

Patent GB-2010784-A (GB)
Title: Signature handling apparatus
IPC: B65H5/10
Filed: 1978-12-14
Abstract: An improved signature handling apparatus includes a sheet transport assembly having a gripper carriage 28 which sequentially moves signatures 80 along a saddle 30 extending through a plurality of operating stations 24, 32, 40. During operation, a stationary signature eg. at 32, is engaged when the carriage is at zero velocity at the end of a return stroke and the beginning of a forward stroke. After the carriage has accelerated, it engages, eg. at 24, a signature which is moving along the saddle under the influence of an infeed conveyor 12. At this time the carriage and the signature are moving at the same speed so that there is no slippage between the carriage grippers and the moving signature. When the carriage is at an end of forward stroke and the beginning of return stroke position and has zero velocity, both of the signatures are released. The carriage preferably includes a pair of shuttle assemblies which are disposed on opposite sides of the saddle. Grippers on the shuttle assemblies are effective to engage opposite side sections of a pair of signature on the saddle. <IMAGE>

Patent GB-2038669-A (GB)
Title: Enhancement of separation of cell layers in centrifuged blood samples
IPC: B01L3/14
Filed: 1979-01-09
Abstract: An improvement in the degree of separation of constituent cell layers in a centrifuged sample of human blood can be achieved by decreasing the natural water content of the red blood cells to increase their specific gravity. Thus, during centrifugation, the red cell layer packs more tightly and separates more completely from the next lighter cell layer adjacent thereto, i.e. the granulocyte layer. This is achieved by adding to the blood sample, before centrifuging, an amount of a suitable additive such as potassium oxalate, lithium lactate or sodium citrate. The additive apparently causes intracellular water to be removed from the red cells by osmosis.
