Title: Improvements in a process of treating cream
IPC: A23C15/02
Filed: 1946-08-15
Abstract: 637,792. Butter ; dehydrated butter oil. THORNTON, A. A. (Creamery Package Mfg. Co.). Aug. 15, 1946, No. 24300. [Class 84] [Also in Groups II and XIII] Butter or dehydrated butter oil is obtained by heating cream to a temperature at which the milk fat is substantially liquified and the cream then separated to produce a portion having a fat content in excess of its serum content, such portion then having passed through a homogenizing machine for the purpose of breaking the envelopes of substantially all of the fat globules to release the liquified fat to form a continuous phase in which the serum is disposed in droplets, thus producing a mixture in which the components are in unstable readily separable relation. Preferably the heated cream after pasteurization is separated to 75 to 80 per cent fat in centrifuge 6 (Fig. 1) and then lead continuously to homogenizing machine 11 of the pressure valve type, which causes an inversion of phases resulting in the fat globules uniting in continuous liquid form. Alternatively a colloid mill of the revolving disc type may be used. The fat in serum mixture then passes to serum separator 49 in which the serum sinks immediately to the bottom from which it is withdrawn via pipe 64. This serum may be returned to the initially heated cream. The supernatant layer of about 98 per cent fat is removed via pipe 63 and may be dehydrated to produce a butter oil with only 0.05 per cent of moisture either by centrifugal action of by spraying into a vessel at 78‹ C. under a vacuum of 68.3 centimetres of mercury. Alternatively, the 98 per cent fat material is forced through composition control pump 116 by means of which salt and serum are blended in calculated quantities from supply reservoir 161 to produce a butter of desired composition (see Group II). It then passes through chiller 217 (see Group XIII) where the butter is cooled to 7‹-13‹ C. It then passes through pipe 245 to form tube 250 after which it is cut and packed. Hydrogenated vegetable oils, honey and maple sugar may be added to the butter.

Abstract: 462,299. Filling-machines. SOUTHALL & SMITH, Ltd., and WEAVER, F. W. Sept. 2, 1935, No. 24445. [Class 94 (i)] In a filling-machine, the bags c are contained in a magazine d, the pile being supported by ledges f and a spring blade h. An oscillating arm i carries a beak which enters the open end of the bottom bag, and transfers it to one of a series of grippers p mounted on a rotary table a. A blast of air is directed through a pipe 14 into the mouth of the bag just before the beak comes into action, to assist the opening. After the beak has returned to its initial position, the grippers carry the bag to a charging station. The grippers p comprise arms o pivoted to the table a, and formed 'with V-shaped pieces at the ends. The grippers are opened by the action of a cam plate u upon pegs v on the arms, and are then closed together by the action of springs q to press the opposite edges of the bag and maintain it in the open condition as shown in Fig. 6. At a subsequent position of rest, a charge of tea &c. is delivered into the bag, which is then carried to a delivery position. Delivery is effected by the action of a striking piece 3 on a projection 2 on the gripper levers o, and the bag falls between compression rollers 7 to a delivery conveyer 8.

Abstract: 1277085 Material spreader C VAN DER LELY NV 13 May 1969 [16 May 1968] 24445/69 Heading A1D  A spreading implement has two flow control plates 29, 30 Fig. 1 situated beneath a hopper 8, material leaving the hopper, passing through holes (33), (40) (Fig. 4, not shown) in the plates, and onto a rotating spreader member 17. A control arm 64 is pivotably mounted on a shaft 50, itself mounted on the frame 2 supporting the hopper, the turning of the control arm 64 about the axis of the shaft 50 changing the radial positions of the setting arms 51, 53 and thus via links 46, 48 connected to plates 29, 30 respectively the position of one plate with respect to another. The overlap of the holes is thus adjustable, and control of the discharge rate of the material from the hopper, achieved. Turning control arm 64 Fig. 5 about its own longitudinal axis alters the position of block 68, moving links 71, 72 which are connected to setting arms 53, 51 respectively, thus rotating both plates to the same extent in the same direction. This adjusts the angular position of the discharge hole (comprising the overlapping holes (33), (40)) relative to the spreader member axis (26, Fig. 3 not shown), which determines the area of land upon which the material is spread, without changing the relative positions of the plates, i.e. the discharge rate. Reference has been directed by the Comptroller to Specification 1247730.

Abstract: 851,318. Sawing ; severing by grinding. RUSSELL & SONS Ltd., S. July 15, 1959 [July 30, 1958], No. 24505/58. Classes 60 and 145. A machine for severing lengths from bars, tubes or the like comprises means for feeding the work between the jaws of a vice 15, 16, a rotary saw or grinding wheel 13 mounted on a pivoted head 12 and a stop 34 which is contacted by the leading end of the work to initiate closing of the vice and is mounted on the head so that as the head pivots to move the tool 13 through the work the stop moves out of alignment with the work to allow the severed length to fall freely to a shoot 18. The work is loaded from a rack 26 on to a roller track 19 by arms 28 operated by a pneumatic cylinder 29 and a rod 30 and is moved along the track by a carriage 20 coupled by a cable 23 to a reversible pneumatic motor 25, the grip of the vice being sufficient to overcome the motor so that it is constantly in action and feeds the work forward as soon as the vice is released. The stop 34 is mounted on a spindle 38 extending from the head 12 and comprises a micrometer gauge 36 engaged by a peg 40 in one of several holes 39 in the spindle and a spring-loaded push rod 46 which, when the leading end of the work pushes it in flush with the end of the gauge 36, operates a switch controlling supply of pneumatic pressure to the vice. If the leading end of the work has not been cut square, the rod 46 is not pushed in sufficiently to initiate a cutting cycle. The vice may comprise a fixed but adjustable jaw 15 and a movable jaw 16 operated by a diaphragm or both jaws may be movable by separate cylinders As the vice closes, it operates a switch which controls a valve 43 supplying pressure to a cylinder and dashpot 42 to pivot the head 12 and tool 13 into engagement with the workpiece and when the cut has been made a switch 44 operated through an adjustable link 50 from the rod 42a resets the valve 43 to withdraw the tool. As the tool moves up, another switch 45 is operated to open the vice and the work will immediately be fed forward again to contact the stop 34. When the last portion of the workpiece has been fed between the jaws of the vice, the carriage 20 operates a switch to reverse the motor 25 until the carriage reaches the outer end of the track 19 and actuates a valve and a switch to cause the arms 28 to load another workpiece and again reverse the motor 25. The motor 25 may alternatively be controlled by a manually-operable valve 32. The tool is driven by an electric motor 14 and an enclosed nylon belt and a spring-loaded guide 33 directs the end of the work into the vice jaws. In a modification, the reversible pneumatic motor 25 for the carriage 20 may be replaced by a reversible electric motor and a magnetic clutch, the clutch being automatically disengaged during the loading and cutting periods.
