Title: Apparatus for weighing and segregating sliced bacon from a slicing machine
IPC: B26D3/28
Filed: 1974-07-16
Abstract: 1468945 Bacon slicing machine CASHIN SYSTEMS CORP 16 July 1974 [10 Oct 1973] 31394/74 Heading A4C [Also in Division G3]  A bacon slicing machine for producing segregated, weighed quantities of bacon, comprises a blade 22 towards which a bacon belly 18 is fed by a pusher 20 with a rate of advance which varies with the cross-sectional area of the belly sensed by levers 31a so as to produce a uniform number of slices in each segregated quantity, a conveyer 40 having one end positioned adjacent the blade so that slices deposited thereon are shingled by the motion of the conveyer, a scale 42 for weighing the bacon on the conveyer, and a computer network 48 and a feed start-stop control 30 operable to interrupt the advance of the pusher when a predetermined weight of bacon has been deposited on the conveyer. A conveyer 50 receives the slices from conveyer 40, said slices being sensed by a photo-electric detector 52 which actuates a scale 54 to weigh the slices once more. If the scale 54 registers a weight outside a prescribed tolerance range, the setting of scale 42 is adjusted on the receipt of a signal from the computer network to weigh either more or less bacon before interrupting the pusher. A conveyer 58 adjacent the trailing end of conveyer 50 receives cards issuing from a dispenser 36 and the slices from conveyer 50 are discharged on to the card. If a quantity of slices is outside the prescribed weight tolerance, a reject mechanism 60, actuated by a signal from the computer network, diverts the quantity to be made up or down in weight, the slices otherwise being permitted to pass to a take-away conveyer 39. The forward motion of the pusher is initiated after a set time interval by the control 30. Conveyer 40 operates at low speeds when receiving the slices from the blade and at a higher speed in transferring them to conveyer 50. The blade comprises an eccentrically shaped or an involute rotary disc and is encased in a housing. In an alternative embodiment, a conveyer (40'), Fig. 4 (not shown) receives the slices from the blade, the motion of said conveyer being stopped on receipt of a signal from the computer network on interruption of the pusher motion, the slices being reweighed while the conveyer is stationary and the stoppage being for about 20 milliseconds. This second weight is compared to the prescribed weight and the difference utilized to proportionally adjust the setting of scale (42').

Title: Improvements relating to tipplers for coal or other materials
IPC: B65G67/00
Filed: 1919-12-15
Abstract: 140,368. Maschinenfabrik Baum Akt.-Ges. March 17, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Rotary tipplers.-Relates to locking- devices for rotary tipplers for coal wagons. The incoming wagon is held by a pivoted stop a until the rotation of the tippler, while emptying the preceding wagon, brings a wedge o against a lever system p and allows the stop a to fall. The wagon then passes over a lever, which raises the stop a into the operative position. As the wagon enters the tippler, it strikes a projection g on a lever f pivoted on a shaft l, and raises the lever, so that it locks the wagon in the tippler, an arm k on the shaft l being simultaneously rocked to move rods m inwards to free the tippler. As the tippler rotates, a gravity catch frees the lever f, which drops and causes the rods m to move outwards ready to engage stops n after the tippler has been rotated to empty the wagon.

Patent GB-955712-A (GB)
Title: Semiconductor devices
IPC: C25D5/34
Filed: 1960-09-13
Abstract: Selected portions of a semi-conductor body are plated by abrading the portions to provide preferentially platable areas and then immersing the entire body in a plating bath; an oxide coating may be used as a mask, the pattern being produced by abrading (or etching) the oxide layer in the preferential areas. Fig. 1 shows a germanium body 10 with mask 12 being subjected to alumina particles projected form an argon jet 22.  The body is then <PICT:0955712/C3/1> deposited in a plating bath so that metal adheres only to the abraded portions of the surface and heated to fuse the surface metal to provide an ohmic or rectifying contact.  Fig. 12 shows a continuous length of dendritic crystalline semi-conductor 76 being passed in front of an intermittent nitrogen abrasive jet 74 and then into bath 82 which deposits indium on the abraded regions.  The crystal passes into a heating chamber 88 which fuses the indium and in front of nozzle 94 which abrades portions of the opposite surface of the crystal. The abraded areas are plated with gold in bath 100 and heating, attachment of leads or other processes are subsequently performed in region 106 where individual semi-conductor devices may be separated from the continuous strip. In a modification, the surface of the semi-conductor is <PICT:0955712/C3/2> covered with an oxide layer before abrasion.  The semi-conductor may consist of silicon, germanium, or an Aiii Bv compound. Abrasion may be effected by liquid or gas jets (carrying abrasives such as particles of alumina, silicon carbide, silicon, germanium, or diamond), ultrasonic vibrations of a liquid medium, abrasive or cutting wheel, abrasive drill or lapping. Plating may be effected by electroplating, displacement plating or chemical reduction. Details of the composition of baths are given for plating silicon or germanium with one or more layers of indium, silver, copper, gold, lead, antimony, gold-antimony alloy, aluminium and thallium.  Two or more metals may be deposited simultaneously or sequentially.  A further doping impurity may also be added by evaporation, ionic beam or gaseous deposition.

Title: Improvements in or relating to grabs
Inventor: GARDINER TERENCE EDWARD GOUVEN
IPC: G21C19/105
Filed: 1959-09-16
Abstract: 931,408. Servicing reactors. BRISTOL AEROJET Ltd. Dec. 14, 1960 [Sept. 16, 1959], No. 31544/59. Class 39 (4). [Also in Group XXX] For lifting articles such as reactor fuel rods, a grab comprises a suspended first part, a second part connected thereto in such manner as to allow limited relative motion between the parts under gravity, a set of cam-actuated jaws movable in concert between open and closed positions, and means whereby the cam is caused to open and reclose the jaws upon relative movement of the said first and second parts in one sense only. The first (i.e. upper) grab part 28, suspended by a cable 10, is fitted into the second (lower) part 14 within which it is held against rotation but permitted a limited axial movement, nut 36 (Fig. 2), on the upper part 28 engaging splines 39 in the interior of the lower part 14 and preventing upward movement of the upper part 28 relative to the lower part 14 beyond the point where it engages the lower surface 38 of a bush 34. The bush 34 is retained by a threaded liner 23 which has an abutment surface engageable with a shoulder 35 of the upper part 28 to provide the other. limit of relative axial movement. When the grab is lowered on to a fuel rod 50 (Fig. 1), the lower part 14 rises with respect to the upper part 28 and causes, by means of helical grooves 45 in the latter, the rotation of a nut 42 of the recirculating ball-type and this rotation, through one-way ratchet means at 51 rotates a sleeve 52 engaged with the interior of a rotatable member 17 whose exterior carries the cam 24 by which the grab jaws 11 are operated. The jaws 11 are three in number and the horizontal cross-sectional shape of the cam is such as to effect opening and reclosing of the jaws each time the grab is lowered on to an article. When the grab is re-lifted, the rotation of the cam 24 is prevented by another ratchet device 56. The exterior of the lower part 14 carries guide fins 13 for engagement with the wall of the tube in which such grabs normally operate. The suspension cable includes an insulated conductor connected to a probe 49 which, when a rod 50 is engaged by the jaws, makes electric contact between the conductor and the grab body and hence the outer layers of the cable 10 so as to provide a remote indication when a rod has been engaged.

Abstract: 968,755. Amphibious bridge and ferry vehicles. H. W. GEHLEN. Aug. 22, 1962 [Aug. 23, 1961], No. 32350/62. Heading B7A. An amphibious bridge and ferry vehicle, having its own drive and control means for use on land and in water, has side floating bodies pivotally attached to its main floating body such that they can be swung out for use in water, and a number of independent ramp members which, when the vehicle is operating on land, are stored on the main body within recesses in the in-folded side floating bodies, and which lie with their upper surfaces in the plane of the main deck, and after out-folding of the side floating bodies can be suspended by their ends from the main body sides and also by swivel means mounted on the side floating bodies to form parts of a floating bridge assembly. Figs. 1 and 2 show the vehicle in its land configuration, with the four ramps 8 stored, two on each side. The two side floating bodies 2 are folded up on to the vehicle, and each has a recess 7 which accommodates the ramps. The vehicle is controlled from a driving cab 3. For use in water, as a ferry or bridge unit, the side floating bodies 2 are pivoted outward to the position shown in Fig. 4, and the vehicle is controlled from a driving position 4. If the vehicle is used as a ferry, the ramps 8 are left in their stored positions since their upper surfaces lie in the same plane as the main deck, thereby increasing the usable area. When used as a floating bridge, either singularly or in conjunction with similar vehicles, a crane 9 mounted on the vehicle is used to transfer the ramps to positions in which their ends are pivoted to the sides of the main deck. Additional support for the ramps is provided intermediate their ends by hydraulic units linking them to the side floating bodies 2. Fig. 6 (not shown) shows propellers mounted in both the main body of the vehicle, and in each side floating body.
