Title: Moulding articles
IPC: B29C45/00
Filed: 1972-05-25
Abstract: 1433136 Injection moulding IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 11 May 1973 [25 May 1972] 24615/72 Heading B5A In a method of moulding an article having a thin wall portion from synthetic plastics material, e.g. a cartridge case, the material is injected in the molten state at a temperature of up to 30‹ C. above the crystalline melting temperature of the material into a mould which is at a temperature lower than the crystalline melting temperature so that the injected material is chilled and molecular orientation is induced adjacent at least some of the mould surfaces to increase the tensile strength of the plastics material in the direction of molecular orientation by at least 80%. The plastics material may be a crystalline polyolefinic polymer, e.g. high density polyethylene. In an example, a cartridge case is produced in a mould 1 comprising a cylindrical cavity 3 having a tubular extension 7 into which can slide a boss 20 mounted on a platen 16. The mould also includes a tubular core 11 surrounding an ejector rod 10. The boss 20 may carry a heat insulating tube 22. The extension 7 may be thermally insulated from the body 2 of the mould by an annulus 9. The mould body 2 has channels (not shown) for continuous water cooling. In operation, the mould parts are partly closed (Fig. 2) and injection effected through a nozzle 19 into the extension 7. After a few seconds delay to permit partial solidifying in a passage 21, the nozzle 19 is retracted and the mould fully closed (Fig. 3). An extension 13 on the ejector rod 10 thus enters and seals the passage 21 so that higher pressure is applied to the material in the mould. The solidified plug in the passage 21 is ejected by the extension 13.

Title: Improvements in shoe pegging machines
IPC: A43D69/12
Filed: 1919-10-08
Abstract: 140,711. Ehresmann, A., and Streibel, F. Oct. 8, 1919. Pegging.-In a lever-drive pegging-machine employing two tools, awl, and hammer, working independently of one another; the tools are not directly connected with the lever but are lifted by cams and driven down by springs, and are carried bodily horizontally by a sliding carriage from one working position to the other. Fabricfeeding and peg-splitting mechanisms are described. An awl 9, Fig. 1, and a hammer 10 are carried on vertically reciprocating rods 4, 5, which themselves are carried in a horizontally reciprocating frame 1 so as to bring first the awl and then the hammer over the horn 61. A work-feeder 11 is carried on a vertical rod 6, and wood pegs are cut by a knife 52. The machine is operated by a band-lever 13, pivoted at 12 and carrying a toothed wheel 14 engaging similar wheels 15, 16 connected to cams 18, 19 which lift the rods 4, 5 upwards by engaging under notches 4<a>, 5<a>. When the rods reach their top position they are held by spring catches 30, 31. As the rods are drawn up, notches 4<b>, 5<b> engage cams 23, 24 and rotate spring-pressed cylinders 22. As the arm 13 passes from the right-hand position shown to the extreme left, the wheel 16 rotates and its lower edge engages a roller 21. This drives the carriage 1, which works in vertical guides 2, to the right and releases the spring catch 31. The spring arm 24 then drives down the hammer 10 on to the work. The backward move ment of the lever 13 similarly drives the carriage to the left, and the awl 9 is released from the catch 30 and driven down upon the work, which is meantime fed forward by the mechanism 11. On the rod 6 is pivoted a pawl 47, Figs. 1 and 4. pressed inwards by a flat spring 48 but which when drawn downwards by the cam 18 engages the bevelled edge 49 and is thrust outwards to release the cam 18. The fabric feeder in its lowest position is engaged by a spring catch 38, and on the movement of the carriage 1 to the left feeds the work in that direction. The amount of feed can be regulated by adjustable nuts 41, 42. At the end of the feed the catch is released and the rod 6 is drawn up by the spring 45. The knife 51 is connected to a lever pivoted at 54 and oscillated by an arm 56 engaging an abutment 8 on the rod 5.
Patent GB-1508662-A (GB)
Title: Sweetening compositions
IPC: A23L27/30
Filed: 1975-06-09
Abstract: Cold-water-soluble synthetic sweeteners are produced which contain as sweetening component an L-aspartic acid derivative conventionally used for this purpose. The desired increased solubility in cold water and the elevated bulk density of this synthetic sweetener are achieved by using a salt serving as diluent or fixing agent and processing this in an aqueous medium together with the L-aspartic acid derivative to form a paste which is then dried to form the end product having stable moisture content. The L-aspartic acid derivative preferably used is the methyl ester of L-aspartyl-L-phenylalanine, to which the desired high solubility in cold water is imparted by this novel formulation process.

Title: Improvements in or relating to apparatus for preventing the aeration of centrifugally treated liquids
IPC: B04B15/08
Filed: 1925-10-06
Abstract: 241,194. Aktiebolaget Separator, (Assignees of Hall, S. H.). Oct. 8, 1924, [Convention date]. Density separators; discharging; leakage, preventing.-A centrifugal separator particularly for purifying oil, has liquid outlets from the bowl enclosed by gas-tight chambers to prevent leakage of gas from outside into the collecting chambers. Transformer oil or other liquid to be purified is supplied through the pipe a to the cup c the flow being controlled by a valve e operated by the float d. When the oil enters faster than the separator can deal with it, the float d rises and stops or reduces the supply by closing the port b. When the separator takes the oil faster than the pipe a supplies it, the float falls and the valve closes the port f to prevent air from being indrawn. A pipe g leads from the cup c to the separator-bowl h which has two discharge passages i, s; the heavier liquid passes through the passage i over the ring j, into the chamber k, while the oil or other lighter liquid passes from the passage s into the chamber 10 enclosed by a copper bellows v. A bearing t is flexibly supported by the bellows and is able to follow the oscillations of the bowl. A pipe 15 connects the chamber 10 to a pressure regulating valve 16 which has ports 17 communicating with the oil discharge pipe 21. The ports are kept closed by a weighted plunger 18, the weight 19 in the oil cup 20 forming a dash-pot. When the separated oil reaches a predetermined pressure the plunger is lifted, and the oil discharged. A pressure is thus maintained in the discharge chamber 10 and air is prevented from leaking in through the bearings. The leakage of oil outwards is prevented by the arrangement shown in Fig. 2. Two annular chambers w, x are formed in the bearing t; they are in communication with grooves m, o, n in the bowl neck, and also by means of the pipes y, z with the oil tank 11. The groove m pumps oil upward from the chamber w, while to ensure against entrance of air to the chamber w the groove o pumps oil from the chamber w to the chamber x from whence it passes to the tank 11 and any air in the oil then separates out. The groove n prevents the escape of oil from the chamber x and in order to ensure this it pumps air which passes along the tube z to the tank 11.

Title: Improvements in and connected with fluid pressure apparatus for operating bulkhead and other doors
IPC: B63B19/00
Filed: 1926-10-09
Abstract: 283,623. Stone & Co., Ltd., J., and Peacock, J. Oct. 9, 1926. Regulating delivery of two or more combined pumps.-A fluid-pressure installation for operating bulkhead and other doors comprises in combination a constantly-running variable capacity motorpump unit a having an automatic capacity control on its delivery, this control being sensitive to pressure conditions in the installation or pump, and a normally idle motorpump unit n having an automatic starting and stopping control responsive to emergency pressure conditions, these motor-pump units being adapted to supply the installation with operative fluid pressure by either individual or joint action. The pump a of the rotary variable-stroke type is coupled with the motor b and its effective stroke is varied automatically. It is connected with a supply tank e through the pipe d and it delivers through a non-return valve f to a connection g leading to an air vessel h, to a non-return valve in on the delivery of the larger pump n, and to a pipe j fitted with a mastercontrol valve k for distributing pressure fluid to the mains r, s of the door-operating devices. The pump n, also supplied from the tank e, is driven by a motor q. The constantly-running pump a is of small capacity, and its function is to maintain a minimum pressure in the installation under normal conditions. When a power demand is made for the operation of one or more doors and the pressure falls below this minimum pressure, the movement of a switch u served by the pump a operates to start the electric motor q and the pump n then operates to satisfy the demand on the installation, the pump n being cut-out when the pressure in the installation has risen sufficiently. The non-return valves f, in on the pump deliveries may comprise screw-down devices, and either of the pumps a or n will function in the event of a breakdown of the other. The electric motors b, q, may be connected with two different sources of power, one being the main dynamo and the other an emergency generating set. An additional control may be added to the pump n in order that it may be operated from the central or other control station. An installation is also described in which the pumps and other parts are more compactly arranged.
