Title: Improvements in and relating to sheeting dies
Inventor: BARAINSKY RUDOLF
IPC: B29C48/49
Filed: 1960-06-23
Abstract: A sheeting die of the type described in the parent Specification has a stirring apparatus arranged inside it in which the stirring implements are formed as pins 511 (Fig. 1). They are preferably offset with respect to one another along the length of the die so that all zones of the die, when viewed in a radial direction, are swept through by the pins.  As shown in Fig. 3, pairs of adjacent pins 5111 may be interconnected at their ends to prevent them from breaking away when of small cross-sectional area.  The material to be moulded may be fed to the die from one or both ends or may be fed to the whole length of the die by one or more screws.  As shown in Fig. 4, the screw 11 has a conical tip 12 rotating in a conical casing 14 which communicates with the die channel 4 through a slot-shaped opening 15.  Each particle after leaving the screw tip 12 traverses the same distance through the channel 4 to the outlet aperture 7 and the effect of friction, and the <PICT:0929629/IV(a)/1> <PICT:0929629/IV(a)/2> <PICT:0929629/IV(a)/3> <PICT:0929629/IV(a)/4> resulting heating and homogenization, are thus the same over the whole width of the die.  In the case of long dies, it is desirable to feed the material by more than one screw, either by two screws directed oppositely to each other and extending over half the length of the die or by two or more screws extending in the same direction and lying either in the same plane or being distributed around the periphery of the die.  A die for making two-layered sheets is shown in Fig. 8 (in cross-section), the materials emerging from the two dye channels 4 passing through the gaps 16 to merge at the tip 17 and pass out together through the lipped slot 2.  The lips 21 are displaceable towards and away from the central plane of the slot 2 by means of screws 18 so that the thicknesses of the two layers can be adjusted independently of each other.

Title: Improvements in and relating to timed electrical switching systems
IPC: H05B41/39
Filed: 1952-09-08
Abstract: 719,677. Switching systems; supply systems for discharge lamps. GENERAL ELECTRIC CO. Sept. 8, 1952 [Sept. 8. 1951], No. 22540/52. Class 38(4) Periodic operation of switch contacts 12, which may be utilized to effect periodic reversal of current in a discharge lamp circuit operating from a D.C. supply, is effected by a cam 11 rotated by a stepping relay 7 having an operating coil 8 which is intermittently energized over the contacts 6 of a timing relay 4 having a coil 5 which is also energized over the contacts 6. Relay 4 is quick to pull-in upon closure of contacts 6 and, thereby, immediately breaks its own energizing circuit. The drop-out time of the relay 4 is, however, arranged to be several minutes, so that a period of several hours may separate successive operations of the switch contacts 12. In the arrangement shown in Fig. 2, for controlling discharge lamps 33 on a vehicle comprising a number of coaches, each coach is provided with push buttons 17, 18, a relay 19 and a battery 16, whereby the lamps throughout the vehicle, supplied from a circuit 32, may be controlled from any coach, whilst the timing relay 4, stepping relay 7 and switch contacts 12 control the periodic energization of a polarityreversing contactor 26 for periodically changing over the connections of the lamps 33 to their supply circuit 32. Operation of button 17 in any coach energizes from the battery 16 a line 15 running throughout the vehicle, so that each relay 19 picks up and holds in from its own battery over its holding contacts 21 and resistor 22. At contacts 23 a circuit is completed for the timing relay 4 and for a relay 28 which connects the lamp circuit 32 to its supply source. Operation of any button 18 short circuits the windings 20 of all relays 19, which thereupon drop out and de-energized all the lamp supply circuits. In a modified arrangement a pair of interlocked reversing contactors are employed which are controlled by a change-over switch operated by the stepping relay.

Title: Improvements in and relating to the production of pressed articles having a pattern extending right through them from materials in powder form
IPC: B29C43/00
Filed: 1937-08-19
Abstract: 491,471. Glass manufacture. SKOLAUDE, H. Aug. 19, 1937, No. 22732. [Class 56] [Also in Group V] Articles having a pattern extending right. through them are produced from powdered materials such as glass powder by filling a mould with the powder, ejecting one or more parts of the material through openings in a matrix by means of profiled plungers corresponding to the desired pattern, filling the spaces so formed in the material with differently coloured powder, and finally subjecting the whole article to a pressing operation. The articles may comprise buttons, buckles, knife handles &c. Apparatus for carrying out the invention comprises a lower mould part B sliding in a, rail 1 and a fixed upper part A which carries the matrix 2 and the plunger 3 sliding therein. The matrix 2 and plunger 3 are independently reciprocated by hand levers 11, 12 through cranks 7, 10 and levers 6, 9 respectively. The mould part B comprises a plate 16 containing one or more mould cavities in which work an ejecting plunger 17 and a patternmaking plunger 18, the two plungers being independently reciprocated by eccentrics 20, 22 actuated by hand levers. The plunger 17 is also adapted to lift the plunger 18 with it when it is operated. In producing an article with a ring pattern, the mould is first filled with black powder and the matrix 2 is lowered thereon. The piston 18 is then raised to eject the centre portion through the matrix, which portion is removed. The plunger 18 is then lowered level with the top of the mould and the matrix is filled with material of a different colour, as shown in Fig. 7, and compressed by the piston 3. The two plungers 18, 3 are then further lowered together to introduce the centre filling into the mould. The lower mould part B is finally moved under a press in which the article is preliminarily or completely pressed. Alternatively the article may be pressed into a recessed press plate by the plungers 17, 18. When making more complicated patterns the article may be ejected into a second mould part where a further pattern is introduced in a similar manner. The upper and lower parts A, B may be arranged in a circle and move relatively to one another. When moulding articles with a target-like pattern, the material forming the outer ring is first introduced, the centre is then filled with material forming the intermediate ring, and finally the centre of this is ejected and replaced by the centre material. The final pressing takes place at a temperature of 1200- 1600‹ C. in the case of glass powder.

[Also in Division G3] A water-cooled engine 11 (Fig. 1) is connected to a radiator 12 by conduits 13, 14 and drives a variable pitch cooling fan having blades 10 and a pitch-adjusting servomotor 15, the latter being connected to a pressure or vacuum source 18 via a temperature-responsive valve 17 mounted in conduit 14. The fan (Fig. 2) has a hub 25 provided with six radial arms 26 in the form of hollow tubular spigots the latter being surrounded by bushes 30 to which the blades 28 are attached at 39, 40. U-shaped torsion springs 33 are attached at 36 to the hub and at 34 to the blades and urge the latter to a zero pitch position. A disc 37 is fixed to the hub to retain the ends of the springs in position. The servomotor comprises an axially fixed piston 45, 46 and a movable cylinder 47 connected to the blades to adjust their pitch via links 50 pivoted at 51 to the cylinder and at 52 to parts 31 of the blades. A fixed conduit 16, 56 enters the cylinder 47 to supply the latter with fluid from valve 17. In Fig. 5 (not shown), a thermally operated switch (20) in line (14) controls a valve (19) in the line between servomotor (15) and power source (18). In Fig.6 (not shown), a valve (60) responds to fan speed to reduce the air-pressure supplied to the valve (17) at high rotational speeds. In a further alternative embodiment, valve 17 is replaced by a valve mounted on stem 56 and operated by a bimetallic member responsive to the temperature of the air passing through the radiator. The links 50 may be replaced by a mechanism comprising an axially movable annular plate having a bayonet joint connection with the servomotor cylinder and co-operating with nylon blocks attached to arms connected to the fan blades. The fan may also be moved with air-cooled engines.
