Title: Method and apparatus for preparing food products for packaging and article produced thereby
Inventor: GREENLY JACK RALPH
IPC: B65B25/06
Filed: 1969-08-06
Abstract: 1282164 Preparing sliced or segmented food products for packaging J R GREENLY 6 Aug 1969 39365/69 Heading B8C A method of preparing a sliced, or segmented, food product such as bacon slices 22 for packaging comprises the steps of treating the slices if necessary so that they will be substantially unaffected by the subsequent application of burning heat, moving individual, or groups of, slices in spaced relationship with one another on to a sheet of heat destructible liner material 30 and applying burning heat to the liner material exposed around the slices, or groups of slices, to destroy the liner material while leaving the slices, or groups of slices, substantially unaffected so that a section of liner material is congruently formed to the peripheral configuration of each slice, or group of slices. As shown, bacon slices 22 are fed from a slicer (not shown) in tandem, to conveyer 10, over a drop off plate 16 and on to another conveyer 24 which conveys them past a nozzle 18 which sprays a thin film of water upon them to protect them against the subsequent short-time interval application of heat. The spacing of the slices 22 on the conveyer 14 is controlled by regulating the relative speeds of the conveyers 10, 14 the speed of the conveyer 14 being also intermittently variable to provide spaced groups of tandemly-arranged slices. The speed of the conveyer 14 may be slowed down sufficiently to provide spaced groups of slices in overlapping shingled relationship. Strippers 26, at the output end of the conveyer 14, transfer the slices 22 on to a thin sheet 30 of slice-separating material 30, such as polyethylene or lightlywaxed paper, which is fed from a roll 30 on to a further conveyer 24 at 32 and is held down on to the latter conveyer by a vacuum head 38 which acts through apertures 36 in the surface of the conveyer 24. The head 38 communicates with a vacuum source 44 through a flue 40 and a smoke filter 42. A gas-fired burner 46, with flame jets 50, provides an open flame across the conveyer 24 to rapidly destroy the separating material 30 around the slices 22 which are unharmed during their brief sojourn under the flame and which are each provided, on their underside, with a thin layer of protective material of corresponding shape. A tabbing structure 52 has an inclined peeling blade 54 the lower edge of which is carried immediately above the surface of the conveyer 24 so that the corresponding marginal edge of each slice 22 is rolled inwardly to expose a tab end of separating material. The conveyer 24 delivers the slices 22 to a controllable, slower speed, conveyer 57 so that the slices 22 with separating liners 30a can be arranged in groups of slices in overlapping relationship. If it is desired to form vertically stacked groups of slices the conveyer 57 is halted periodically to collect the groups. When slight burning of the product is of no consequence the spraying nozzles 18 are eliminated.

Abstract: 1312155 Dual circuit brake valves BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO 18 Aug 1970 [17 Sept 1969] 39649/70 Heading F2F A dual circuit compressed air brake valve assembly includes respective inlet and outlet ports 11, 12 and 13, 14 for the two circuits and the inlet and outlet ports 11, 12 and 13, 14 are connectible by downward movement of valve elements 28, 90 out of engagement with seats 26, 116; valve element 28 is moved by the skirt 64 of a graduating piston 58 and valve element 90 is moved by a lower edge 88 of an exhaust plunger 48 integral with a relay piston 84 and the components 64, 88 thereby act as exhaust valve seats. On opening the inlet valve 26, 28 cavities 22 and 24 are connected and on opening inlet valve 90, 116 cavities 95 and 82 are connected. The cavity 24 is permanently connected to a relay cavity 80 above the relay piston 84 by means of a passage 86 in a wall 20. A rod 55 extends through the piston 58 into the passage 50 of the exhaust plunger 48 and a precompressed spring 59 is disposed between a head 54 of the plunger 48 and a disc 57 fixed to the rod 55 and slidable in passage 50. The piston 58 is movable by means of a foot pedal (not shown) which acts on the piston 58 via a disc 66 and a rubber graduating spring 74. The piston 84 will also move downwardly in unison with the piston 58 by virtue of the engagement of an enlarged collar 61 of the rod 55 and the piston 58; as the piston 58 moves downwardly the rod 55 will move downwardly and the relay piston 84 will also move downwardly until valve seat 88 closes on element 90. When this occurs, the piston 58 moves a short additional distance by virtue of a clearance which exists between the lower end of a neck port 70 of the piston 58 and the upper end of the head 54 and this collapses the spring 59 to relieve its load from the relay piston 84. The full force of a spring 118 is thereby transferred to valve element 90 and when the upper inlet valve 26, 28 is opened air pressure in cavity 80 plus the force of spring 118 acts to open the valve 90, 116 against the force of spring 112. If the fluid pressure in the first circuit fails the inlet valve 90, 116 is operable manually by downward movement of the exhaust member 48. The cavities 24 and 82 are exhaustible through the valves 64, 28 and 88, 90 and thence through a one-way valve 106; slots 52 connect the exhaust passage 50 and the cavity 24 when the valve assembly is in the position shown.

Abstract: 1,193,362. Indoor football game. B. BAILEY 4 Sept., 1968 [23 Aug., 1968], No. 40463/68. Heading A6H. Apparatus for playing a game simulating football comprises a substantially flat table-like surface I surrounded by an upstanding boundary and representative of the field and having a goal at each end, an array of horizontally pivoted flaps 2 normally enframed in the surface, each one of which is connected to a key 5 so as to be pivotally raised by its conresponding key, half of the flaps being thus operable in one sense of direction in opposition to the other half, the halves representing teams, some of the flaps being located immediately adjacent to an oppositely movable flap and others being located separately from but in mirror-image symmetry with an oppositelymovable flap, the positions and spacing of the flaps and the boundary being such that a ball in the field area will not rest on a level part of the surface out of the effective reach of some flap, and the keys 5 being disposed outside the boundary 'behind the goals, in two sets oorresponding to the two teams. Each flap 2 normally lies in a depression formed in the surface which is just deep enough to enframe the flap with its exposed upper face level with the surface. The corners of the surface at the goal lines and side lines may be slightly sloped downwards towards 'the middle of the surface. Some of the flaps 2 may have upward projections 9 so as to impart a directional component of motion to the ball transverse bo the length of the field area. Each key 5 is connected to the corresponding flap by a tension element, suitably a link wire 6, and each has associated with it a stop 8 to limit the extent to which is can be depressed. The flaps may be of rectangular shape and the pivotal axes of all flaps may be parallel with the goal lines. Thus in Figure 1, depression of keys 5, pulling the wires 6 operates the flaps 2. As shown, there may be eleven playing flaps each side of the centre line or alternatively only seven such flaps may be provided. The playing area may (be surrounded by a net of plastics or other material 12 which has openings at each end to form the goals.
