Filed: 1970-09-21
Abstract: 1322546 Valves ILLINOIS TOOL WORKS Inc 21 Sept 1970 [19 Sept 1969 (2) 8 Dec 1969] 44905/70 Heading F2V A device for constricting a part of a flexible tube (64) (Fig. 6A, not shown) comprises a base member 22 having a base surface 36 which is at an angle to two laterally spaced reference surfaces 32, 34, and a clamping member 24 having a surface rolling on the reference surfaces and forming a channel with the base surface 36 so that flexible tubing in the channel can be variably restricted. The clamping member may be a roller held in a yoke (Fig. 1) or held in a channel formed by extending the sides of the base member and providing a sliding lid (100) (Fig. 7, not shown) An extension (150) (Fig. 12, not shown) enables the flexible tube to be rotated through 90 degrees and constricted in a slot (162) to terminate fluid flow through the tube. The base member may have a pair of circular reference surfaces (Fig. 16, not shown) which together with eccentric base surface (31c) and circular clamping surface form the channel of variable depth. In an alternative embodiment (Fig. 5A, not shown) the base member and clamping member are of arcuate form; protuberances (120a) on the clamping member mate with holes (122a) on the base member.

Abstract: 1,211,197. Delivering measured quantities of liquid. FILLING MACHINES Ltd. 8 Jan., 1968 [8 Oct., 1966], No. 45068/66. Heading B8N. Apparatus for delivering measured quantities of liquid e.g. molten metal comprises a liquid container, an upright discharge tube in the base of the container with its intake end within the container and its discharge end outside the container, liquid measuring means mounted for reciprocable sliding movement on the tube, and means for controlling the amount of liquid discharged from the measuring means into the tube. As illustrated the measuring means is a cup 10 slidable on the discharge tube 11 and connected to a piston 20 reciprocable in its cylinder 21. The control means is a stop member 23 whose height is varied by means of a worm-wheel and screw arrangement 22. The liquid container 5 includes electronic probes 25, (24) (Fig. 2, not shown). Probe 25, when liquid in container 5 reaches a low level, actuates a solenoid-operated pneumatic valve 6 to permit flow of liquid from a bulk supply container 1 to the container 5. When the liquid reaches the other probe the supply is terminated. The intake end of the discharge tube is above the lower end of the other probe. A further probe 9 indicates e.g. by means of a lamp when the liquid level in the bulk container is getting low. Thermostatically controlled box heating elements 2, 8 are provided to keep the metal in its molten state. Splash guards 14, 15 are provided. An oil layer 3 is provided to inhibit formation of metal oxides.

Title: Improvements relating to process and apparatus for producing metered quantities of uncured elastomeric compositions
IPC: B29C48/92
Filed: 1968-09-24
Abstract: 1,246,822. Cutting extruded blank lengths., PIRELLI S.p.A. 24 Sept., 1968 [29 Sept. 1967], No. 45255/68. Heading B5A. [Also in Division G1] In a moulding process wherein a predetermined sequence of blanks of elastomeric material of the same of different lengths (and hence weight) are required for a number of moulding presses, the blanks are cut from the material 25, intermittently issuing from the extruder 18 of Specification 1,017,183, by a reciprocatory wire cutter 31 at the die simultaneously with or immediately after the extruder has been halted, a light source and and photo-electric cells 30d and 30a-30c being provided on opposite sides of a trough 28 along which the extruded material passes and being connected to a control circuit whereby the desired sequence of blank lengths is automatically produced. The blanks comprise a rod, slab, or tube of constant cross-section. The feed to the extruder comprises a band 6 delivered between a driving roller 8 and a pressure belt 8<SP>1</SP> and which is cut into a continuous strip of reduced width between the fixed and moving blades 11, 12 of a cutter and passes to the extruder hopper 17 from a weight actuated device 50 which controls the stopping and starting of the band cutter. The photoelectric cells 30a-30x are spaced along the trough at points corresponding to each of the required blank lengths and are each connected to an AND gate circuit (33a-33c), Fig. 2 (not shown), which is prepared for signal passage when cell 30d is " out " by the passage of the material. Programme selectors (35a-35c) determine which gate circuit passes a signal to an OR gate circuit (36) which, via respective flip-flop circuits (37 and 41), stops the extruder 18 and actuates cutter 31. On removing the cut length from the trough 28, all the photoelectric cells 30a to 30d are "on," the latter issuing a signal to the gate circuits (33a-33c) which is permitted by the programme selectors (35a-35c) only to pass from the last actuated photo-cell to reciprocate the cutter 31 to its cutting side of the die and to restart the extruder by the aforestated circuits. Decade counters 34a-34c respectively associated with photo-cells 30a-30c record the production of each length of material. A selection circuit 39 prepares the circuits associated with each photo-cell for the production of a further sequence.

Title: Improvements in or relating to the manufacture of biscuits
IPC: A21D13/00
Filed: 1963-11-19
Abstract: In making a cracker biscuit beans (e.g. Indian red bean, kidney bean, broad bean) are softened by boiling and the skin and other undesired solid substances removed by filtration.  Hydrase (e.g. amylase) and protease are added to the dough prepared from the above process to decompose starch and protein.  The mixture is allowed to stand for 10 to 15 hours at 30 DEG C.  Suitable amounts of wheat flour, jams, sugar and cooking fat are blended into the mixture to form a hard paste.  The paste is cut into pieces which are each enclosed by ordinary cracker dough moulded and baked. Cysteine may also be added to the bean dough before shaping and baking.

IPC: B31B50/62
Filed: 1963-11-25
Abstract: A machine for applying a liquid coating to a moving article comprises a rotatable roller 30 for applying the liquid, a carriage 4, which is movable in an orbital path for collecting articles successively, feeding each article to the periphery of the roller and releasing the article and an actuating means which operates during the feeding motion of the carriage for causing rotation of the roller at a speed such that the linear speed of its periphery corresponds to the linear speed of the carriage. In the arrangement shown there are two glue applying assemblies, one on either side of the machine for applying glue to opposite side margins of carton blanks, and each comprises a pre-melting container 25 with an adjustable outlet leading to reservoir 27 which has an overflow chute and an adjustable outlet orifice on to roller 30.  Electric heating means are provided for container 25, reservoir 27 and roller 30.  In the case of the latter the heating elements are fed via brushes and slip rings on the driving shaft. The carriage 4 is moved in an orbital path by swing lever 18 through cam and link mechanism operated by motor 1 so that the fingers 4A of the carriage rise and fall relative to platform 3 so as to collect carton blanks from one end of platform 3 and deliver them to the glue applying assemblies at the other end.  Each forward movement of the carriage is arranged to effect driving of chain 37 which through gearing, drives shaft 41 and hence via chain 36 rotates the gluing rollers 30 so as to feed and glue the carton blank directly previously supplied to the gluing units.  The blanks are subsequently forwarded to a carton forming apparatus.
