Title: Improvements in or relating to automatic feed devices for sheet materials
Inventor: BARSBY CHARLES RUTLAND
IPC: A23G7/00
Filed: 1955-12-30
Abstract: 793,732. Feeding sheets. SCRIBBANS-KEMP, Ltd Nov. 30, 1956 [Dec. 30, 1955], No. 37393/55. Class 100(1) Sheets 2 in a container 1a, Fig. 2, are fed successively from the bottom on to a conveyer belt 3, are supported on the belt, and the forward end of the bottom sheets and the adjacent part of the belt are pulled downwardly by a suction device 7 so that the bottom sheet is enabled to pass through a gap at the bottom of the forward end of the container 1a. The separation is by the frictional force between the sheet and the belt. As described, the apparatus forms part of a machine for making wafer sandwich biscuits and the sheets 2 are wafers. The conveyer belt 3, which is of open mesh construction, is supported by rollers 4 and plates 14 to hold the belt in a plane which touches the bottom end 6 of a plate 5 on the container front. The suction device 7, covered by a perforated plate 8, is arranged at a distance below the end 6 of slightly more than one sheet thickness. To facilitate sheet separation and prevent jamming, the container front 1a may be inclined as shown and a roller 4a may be arranged just behind the rear edge of the bottom sheet at a higher level than rollers 4 to take some of the weight of the pile when initial forward motion of the bottom sheet 2 is effected. In the form shown in Fig. 3, a gate 15 is hinged at 16 to a plate 17 on a plate 18 integral with or adjustably mounted on the wall 1a, and the gate 15 may be oscillated continuously through a small distance, limited by a stop 19, by known means such as a vibrator, cam, or solenoid. The gate 15 and plate 17 may be replaced by a single spring plate. In modifications, the container itself may be reciprocated in the direction of travel of the belt 3 by a cam which moves the container forward faster than the belt, and imparts a relatively slow backward movement. Alternatively, the belt 3 may be driven in an intermittent manner, and it could be reversed through a small distance at each stop. The sheets 2 may be fed into the container 1a continuously by a conveyer belt system, or down an inclined plane, and an air jet is arranged to float each sheet into the container as it leaves the plane or conveyer.

Title: Improvements in or relating to joints for tubes and pipes
Inventor: YOUNG GEORGE BERNARD ARTHUR
IPC: F16B7/04
Filed: 1962-10-05
Abstract: 1,006,952. Pipe joints. RAPID METAL DEVELOPMENTS Ltd. Nov. 6, 1963 [Oct. 5, 1962], No. 37726/62. Heading F2G. A joint for joining together in end-to-end relation a pair of tubes or pipes 6, 7 comprises a spigot portion 5 secured to the tube 6 and formed with at least one recess 5a in its extension surface, the tube 7 having at least one inwardly extending projection and the arrangement being such that the joint can be assembled by inserting the spigot portion into the other tube with the recess out of alignment with the projection and then twisting one tube relatively to the other so that the projection enters the recess. The inwardly extending projections on the tube 7, Fig. 1, are formed by the material lying between the periphery of a plate 8 secured to the end of the tube and the four edges of a square aperture cut in the plate. The size of this square corresponds to that of the cross-section of the spigot and when the spigot 5 is pushed into the aperture until the recesses 5a are aligned with the plate 8 and the tube 6 is twisted, the projections on the plate 8 extend into the recesses 5a, the bases of which are inclined as shown to give each a leading edge 5c and a trailing edge 5d whereby, when the tube 6 is twisted, the trailing edge 5d of each groove comes into wedging engagement with adjacent sides of the aperture in the plate 8 so that further turning is prevented. In the embodiment shown in Fig. 3 the spigot is of cruciform cross-section with recesses 5a in the limbs and the projections 7a in the bar 7 are inwardly pressed dimples and wedging action is obtained by inclining the sides 5e of the recesses. The bar may be of other re-entrant polygonal cross-section.

Abstract: 911,661. Pallet trucks. COLLIS & SONS Ltd., J. Dec. 15, 1958 [Dec. 13, 1957], No. 38934/57. Class 78 (3). [Also in Group XXIX] In an hydraulic motor-operated machine, e.g. a load handling machine, press or jack, a three-way selector control valve unit comprises a non - return valve V4, V23, Fig. 2, controlling flow between a supply port B and a discharge port D and a similar non-return valve V12, V25 controlling flow between the supply port B and an outlet port C. The ports B, C, D are in a body A which has a two-diameter opening accommodating the two-part valve unit V having ports VB, VC, VA which register with body ports B, C, and D, respectively, the ports VA and VB being covered with oil filters V18, V17, respectively. The seats V23, V25 of the non-return valves are of truncated hollow form. A thrustrod V13 having flattened sides is located between the valve members V4, V12 and there is provided a plunger control member V5 which is bored to receive a spring V20 which acts on a thrust-rod V22 for controlling the valve member V4. The plunger V5 is operated against the action of a returnspring V6. The valve may be used with an operator-operated pump or a variable-speed pressure type pump or with a pump of the independent constant-speed and/or constant pressure type. The plunger V5 can be depressed by varying extents to effect the necessary port connections for motor operation. If the plunger is depressed to open both valves completely the valve unit is then in the neutral unloaded position. The plunger V5 may be depressed to a position which locates the ball V4 or both balls V4, V12 in their conical seats V23, V25 so that they effect a metering control and thus determine the speed at which the motor operates. When the plunger V5 is fully withdrawn the balls V4, V12 operate in non- return manner. As described, the selector valve is used to control the operation of the platform of an hydraulic truck or stacker.
