Abstract: 1,180,541. Labelling machine; endless con-veyers. SOC. FRANCAISE D'ETIQUETAGE VIREY & GARNIER. 5 Feb., 1968 [15 Feb., 1967], No. 5743/68. Headings B8A and B8F. A portion 38 of a label is in advance of a container 12 to which it is synchronously attached at 12c by a label feeding unit 7 on one side of the conveyer channel, as seen from the top, Fig. 1. This leading portion 38 of the label is then folded back on to the forwardly presented part of the container by the action of e.g. air jets or reciprocating brushes at 32. The unattached portion 38a of the label is then smoothed on to face 12b as the container moves in front of the smoothing means 27 at 14. Check rollers 30, 31 cause the container to rotate about a vertical axis through its centre at 15 and 18 respectively, thus enabling smoothing means 28 and 29 to complete the application of the wrap-round label so that there is an overlap. Alternatively, the conveyer belts may be made of spongy material to facilitate pivoting of the containers, the check rollers 30, 31 being replaced by non-driven smoothing rollers mounted at the ends of spring-biased articulated levers (Fig. 2), or by e.g. foam rubber guides or oppositely directed air jets. An air jet or suction system (not illustrated) may help support the label on the conveyer belt as it is being presented to the container by the suction roll 7. Spring blades projecting slightly into the container path may direct the containers into engagement with the check rollers; auxiliary conveyer belts may replace the guide rails at 35, 36 and 37; a pair of pincers may replace the air jets at 32.

Title: Mechanical position holding mechanism more particularly for a seat
IPC: A47C1/024
Filed: 1961-02-17
Abstract: 928,211. Seat adjustments. ANDERSON CO. Feb. 17, 1961 [Feb. 19, 1960], No. 5904/61. Class 52 (2). [Also in Group XXV] A seat adjuster for controlling the position of a pivoted back 12 relative to a seat 10 comprises a telescopic stay 35 fastened at its one end to the back 12 and at its other end to a bracket 29 fixed to the seat 10, the stay 35 comprising a nut 40 and screw 42 (Fig. 3), brake means operatively engaging the screw 42 for preventing rotation of the screw and for preventing the back 12 from moving to the horizontal position, and means for releasing the brake means so that the screw 42 is manipulatable for adjusting the back 12 between a vertical and a horizontal position. The stay 35 consists of an elongate tubular member 37 pivotally connected by a bracket 38 to the back 12 and of a bifurcated support member 51 axially aligned with and spaced from the tubular member 37. The member 51 is pivotally supported on the bracket 29 and also pivots on an actuating rod 53. A cup-shaped member 58 slides in the member 51 and is urged away from the tubular element 37 by a spring 68. The rod 53 has a cam-shaped portion 72 for bearing against the outer face of the member 58. The screw 42 has an unthreaded end 54 extending into the member 58. A brake disc 81 is keyed to the screw 42. A spring 49 in the tubular element 37 urges the screw towards the support member 51. The rod 53 is rotatable by a handle 77 for urging the brake disc 81 into braking engagement with the end face 85 of the member 51 to prevent relative rotation between the screw 42 and the member 51. The handle 77 is also used to release the brake disc. In operation, with the back 12 in a vertical position and with the rod 53 in the position shown in Fig. 3, any clockwise pressure against the back 12 urges the screw 42 with the braking disc 81 against the end 85 of the non-rotatable support 51 to thereby prevent any rearward movement of the back 12. Rotation of the rod 53 by the handle 77 to the position shown in Fig. 4 will force the cup member 58 and the screw 42 axially of the support 51 against the force of the spring 68 so as to raise the brake disc 81 from the end 85 of the support whereby any clockwise pressure on the back 12 urges a plate 46 against the end of the screw 42 to rotate the screw until the handle 77 is released or a part of the nut 40 engages with a stop washer 87 on the screw 42. With the brake 81 released the back 12 can be moved in either a clockwise or a counter-clockwise direction between the limits of movement provided by the stop 87 or stop pin 103 on the screw 42. Pressure on the seat in a counter-clockwise direction will raise the seat whether or not the brake 81 is in the looking position shown in Fig. 3.

Title: Beam therapy apparatus
IPC: G21F5/02
Filed: 1952-03-10
Abstract: 699,845. Therapeutic radiation apparatus. ELDORADO MINING & REFINING (1944), Ltd. March 10, 1952 [March 8, 1951], No. 6180/52. Class 98 (i). [Also in Group VI] The apparatus includes a radio-active source of high energy γ-rays enclosed by a container impervious to γ-rays having an outlet for the emission of a beam, wherein the beam is controlled by apparatus comprising gravity operated means for supplying mercury to close the outlet, means for removing the mercury from the outlet by displacing it to a higher level by means of a compressed gas, means comprising said compressed gas for keeping the mercury out of the outlet, means for releasing the compressed gas from the outlet whereby the mercury will pass into the outlet, and means pervious to γ-rays to prevent the mercury from escaping through the open end of the outlet. As shown, a γ-ray source 10, such as Co<SP>60</SP>, is enclosed by a container 11 of dense material such as lead, and has a conical outlet 14. A sloping window 16 closes the outlet, which can be filled with mercury. A safety window 17 may also be fitted, both windows being of material pervious to γ-rays, such as stainless steel. The mercury may be removed by compressed air, which is blown in by a pipe 28 branching at 29, 30 and so forcing the mercury up pipes 19 (only one of which is shown) into a reservoir 21. A sump 23 is provided, from which pipes 19 branch on either side, the arrangement being such that a mercury seal prevents air from entering pipes 19. Reservoir 21 is crescent shaped, and is of such a size that when the mercury is forced into it, the air therein is compressed and helps to return the mercury when pressure is released. The floor 24 of reservoir 21 is parallel to window 16, and the pipes 19, 28, 29, 30 make angles with the base of the container lying between the angles made with the base by window 16 and the side 18 of outlet 14. By this means, the container can be tilted between a position in which window 16 is horizontal and a position in which the side 18 is horizontal without impairing the working of the device. To open the radiation path, a switch is closed in an electric circuit which starts a compressor, which blows air down pipes 28, 29, 30 and closes a solenoid valve. A pressure-sensitive switch connected to reservoir 21 breaks the circuit to the compressor when all the mercury has been forced out of the outlet 14. Should pressure fall due to leakage, allowing mercury to return, the pressure switch re-starts the compressor until the mercury has been forced out again. When the operating switch is opened, the solenoid valve opens to let out the air in outlet 14 and the mercury returns. A hand-operated valve may be connected to release the pressure if the solenoid-operated valve should stick. The failure of any other part of the system results in an immediate return of the mercury to outlet 14, thus cutting off the radiation.
