Title: Food patty moulding machine
Inventor: RICHARDS LOUIS R
IPC: A22C7/00
Filed: 1973-01-15
Abstract: 1423701 Moulding food patties FORMAX Inc 15 Jan 1973 [24 Jan 1972] 1932/73 Heading B5A [Also in Division F1] A food patty moulding machine includes a hopper 25, Fig. 4, an endless belt 31 delivering the food, e.g. meat or fish, to an opening 39 with feed screws 51-53, Fig. 17, delivering the food to the intake of a pumping system 26, Fig. 5, comprising two pumps 61, 62 operating in synchronism to continuously force food into a manifold 27 supplying moulding means 28. The latter includes a horizontally reciprocable plate 32 with laterally spaced mould apertures 126 supplied from the manifold outlet 111. When the mould plate is extended a series of knock-out cups 33 are lowered to discharge the patties to a conveyer. Should the food at the delivery end of the belt 31 exceed a predetermined level, sensing means 55 interrupt the conveyer drive. The cups 33 are detachably supported on a bar 146, Fig. 14, on vertically reciprocable members 147 pivoted to rocker arms 149 pivoted at 151. A notched cam holds each arm in the position shown, but on rotation of the cams by a drive connected to the mould plate drive the arms and hence the cups are lowered by springs 152. The knock-out mechanism may be raised from the mould plate by a motor 169 driving pinions 164 engaging racks 163 on bars 162 fixed to a plate 122. The pumping system includes the two pumps 61, 62 with plungers 68, 88 in cavities 69, 89 respectively. When the plunger 68 is extended into its cavity, Fig. 4, the feed to the other cavity 89 is provided by screws 51, 52, likewise the feed to the cavity 69 is provided by screws 52, 53. The capacity of each cavity is at least several times that of the mould plate, so that each pump operation can supply the moulding means for a number of moulding cycles. The manifold 27 houses a rotary valve cylinder 101, Fig. 5A, with slotted apertures 107, 108, Fig. 7, which are alternately brought into alignment with outlets 73, 93 in the pump cavities 69, 89; a skewed slot 109 in the cylinder overlaps with the manifold outlet 111 to provide a more uniform feed to the mould apertures. The pumps are driven by hydraulic cylinders 64, 84 with ports 65, 66 and 85, 86 respectively, associated with high and low pressure hydraulic pumps forming part of an hydraulic control system including pressure sensing devices 78, 98 connected to each pump cylinder. The initial part of the working stroke of each plunger is effected at low pressure and the remaining part at high pressure, such high pressure being supplied to the drive cylinder of the pump automatically in response to the plunger stalling against food in its cavity. The valve cylinder 101 is driven by an hydraulic cylinder 106, Fig. 5, which is also connected to the control system and operated automatically in response to a plunger stalling against food trapped in its cavity.

Title: Improvements relating to the manufacture of bricks or blocks, slabs and the like
IPC: C04B38/00
Filed: 1951-01-25
Abstract: In making constructional or heat-insulating bricks, blocks, slabs &c. a porous light-weight, aggregate, produced by firing a clay, is coated with a slurried bonding agent and formed into the bricks &c. which are then fired in a furnace at a temperature high enough to bond the particles of aggregate together without causing them to flux completely, e.g. 1050 DEG C., the bonding agent being chemically stable at the firing temperature and present in an amount insufficient to fill the spaces between the particles of aggregate. Preferably, the volume of slurry used should not exceed 10 per cent. of that of the aggregate particles.  The bonding agent may be a glaze or a clay which will fuse before the aggregate.  A wetting agent may be incorporated in the slurry.

Filed: 1968-01-15
Abstract: 1,173,875. Electroluminescence. GENERAL ELECTRIC CO. 15 Jan., 1968 [15 Feb., 1967], No. 2094/68. Heading C4S. [Also in Division H1] A contact to P-type II-VI semi-conductor which is non-rectifying over a wide temperature range is formed by diffusing alkali metal atoms into a region of the P-type surface, by forming a second surface region partially overlapping the first region and containing gold atoms and by providing a metal layer in contact with at least parts of each of the two regions and their area of overlap. In one embodiment a zinc telluride body is provided with two ohmic contacts. The regions 5, 5<SP>1</SP> are formed by applying a solution of lithium nitrate to the surface, removing the solvent, and heating to diffuse in the lithium which acts as a shallow level acceptor and gives the final contact its ohmic character at very low temperatures. A solution of chloroauric acid is applied to adjacent regions partially overlapping the diffused regions 5, 5<SP>1</SP> and reacts with the telluride to incorporate gold into regions 6, 6<SP>1</SP> and leave a gold film on the surface-the structure is heated to complete formation of the regions 6, 6<SP>1</SP>. An indium-silver (3%) alloy is pressed-on to complete the contact 8 and a similar alloy is used to solder the body 1 to a heat conductive copper plate 2. The injection laser of Fig. 2 (not shown), has a zinc selenotelluride body with a P-type region doped by copper, silver, phosphorus, arsenic, antimony or bismuth or by zinc defects, and an N-type region doped with gallium, indium, aluminium chlorine bromine, or iodine. Indium-5% mercury amalgam is used to join the body (via the N- type region) to a copper heat-controlling body, and the alkali metal/gold ohmic contact is used to connect to the P-type region. In general variants the semi-conductor body may be a telluride or seleno-telluride of zinc and/or cadmium e.g. M.Te x Se (1-x)  where x is 0.2 to 1 and M is Zn and/or Cd; lithium, sodium, potassium or rubidium may be the alkali metal; and the contacting metal may be lead, tin, silver or gold or may be lead, tin or indium containing a few per cent of copper, silver, phosphorus, arsenic, antimony or bismuth. The source of alkali metal for diffusion need not be the nitrate; many other salts are suggested. The devices formed may be solar cells, photocells, or injection lasers-the special contacts being ohmic and non-rectifying over a temperature range from 26-373 K.

Abstract: 1454442 Liquid/liquid contact and separation PELLERIN/ZBNITH AB 17 Jan 1974 [18 Jan 1973] 02236/74 Headings B1D and B1F Apparatus for the continuous acid treatment of soapstock comprises a reaction vessel 1 in series with a separating device 12 for separation by settling in one or more chambers of the product fatty acid from aqueous solution. The reaction vessel comprises an elongate vessel 2 closed at one end and fed by a supply pipe 5 for soapstock having an open end and a supply pipe 6 for acid having a closed end but a perforated side wall in its end portion. Means for agitating the reaction mixture, e.g. a perforated pipe 9 to which gas is supplied, is present in the reaction vessel. Reaction products pass by overflow 10 to the settling device. As illustrated, the settling device comprises a cylindrical housing divided by perpendicular transverse and longitudinal baffles 13, 14 to provide four settling chambers connected in series by upper and lower openings 19, 20 for the passage of acid and aqueous phase, respectively. The vessel is inclined to the horizontal so that there is an upward slant from chamber 17 to chamber 18 to aid collection of fatty acid. Chambers 15 and 16, in result, would have a slope in the wrong direction and so a false sloping roof 21 is provided in these chambers. The fatty acid and aqueous phase are removed from the final chamber 18 by means of overflow-controlled outlets 23, 26, respectively. The aqueous phase overflow 26 is at a slightly lower level than acid overflow 24 and is vertically adjustable for height. Gas vents 29, 30 are provided above the overflows. A sludge outlet 22 is provided at the lowest portion of the separator and communicates with the aqueous phase outlet. For Figures see next column

Abstract: 855,404. Thawing and warming frozen food. BURGER EISENWERKE A. G. Jan. 28, 1958 [Jan. 29, 1957], No. 2776/58. Class 49 Frozen provisions, especially ready prepared foodstuffs, are thawed and warmed on vertically superposed racks in a thawing chamber by circulation of heated air through horizontal spaces between the racks, and the direction of flow of the heated air is changed at least once during the thawing and warming. When the air is circulated by an axial flow fan, the direction of flow may be changed by reversing the rotation of the fan, by pivoting the fan about an axis perpendicular to the axis of its rotation, or by a rotary valve which connects oppositely disposed air conduction shafts alternately to the pressure and suction side of the fan. Referring to the Figure, air is forced through a conduit 14 from an axial flow fan 10 into the upper half 13a of a rotary valve 13 for supply to either conduit 4a (as shown) or 4b. The circulated air returns to the lower half 13b of the valve from the opposite conduit (as shown, 4b) into the suction inlet 18 of the pump. The rate of change of the direction of flow is preferably increased after an initial thawing and operation of the electrical heaters 9 is phased with rotation of the valve so that only air from the pressure side of the fan is heated. In an alternative embodiment (Figs. 3, 4, 5, not shown) the impeller of the fan is fitted in the lower chamber 136 of the rotary valve. In a further embodiment (Figs. 6 and 7, not shown) four air-conducting conduits are employed.
