Title: Improvements in power presses
IPC: B30B1/26
Filed: 1949-08-17
Abstract: 665,250. Mechanical presses. WILKINS & MITCHELL, Ltd., and WILKINS, E. W. Aug. 15, 1950 [Aug. 17, 1949], No. 21369/49. Class 87(ii) Relates to power presses of the type in which a tool-carrying slide 2 - is moved relatively to a stationary tool-carrying bolster 16, and in which movement of the slide is transmitted from parallel shafts 6, 6, extending forwardly and rearwardly of the press. According to the invention, openings 13 are provided in the side walls of the press, through which openings the slide can be put into place and removed, thus permitting a front opening 17 (through which it has been usual to insert and remove the slide) of less width and height than the slide. As shown, the openings 13 are occupied by gibs or guides 3 which guide the slide, and when the slide is to be removed through an opening, the guide must be removed first. The gudgeon pins 11 are removed through holes 12x in the front and rear of the press (the press being of rectangular box-like structure, open at top and bottom and made from heavy rolled steel slabs welded together). The guides 3 are V-shaped in section and are secured to the side walls of the press, shims 15 being interposed to allow for inward adjustment as wear takes place. As shown, the slide is reciprocated through connecting rods 4 by two eccentrics 5 on shafts 6 driven by spur wheels 7 from common pinions 8 on a first motion shaft 9 driven by a friction clutch at one end and having a brake at the other end. There are two spur wheels 7 for each eccentric, one on each side of it, and there are two pinions 8, whereby a balanced drive is obtained.

Title: Improvements in or relating to time controlled electric switches
Inventor: BOWEN TOM
IPC: H01H43/02
Filed: 1956-07-11
Abstract: 809,867. Time switches; cam-operated switches. SMITH & SONS (ENGLAND), Ltd., S. June 20, 1957 [July 11, 1956], No. 21501/56. Class 38 (5). A time switch, which is operated by a periodically acting time-control mechanism, incorporates an overriding hand-control member which is movable from an inoperative position in either of two directions so as to open or close the switch and which is returned to the inoperative position by the time control mechanism. As shown, a disc 10, which is rotated once every 24 hours by a synchronous motor, carries a pair of tappets 11 which engage a star wheel 12 fixed to one end of a rotatable sleeve 13 carrying at its other end a cam 14 having pairs of lobes 15. Contact springs 16, 17 carrying contacts 18, 19 bear on the cam lobes so that the first anticlockwise movement of the star wheel 12 causes the spring 16 to drop off its corresponding lobe 15 and thus open the contacts and the second anticlockwise movement of the star wheel causes the spring 17 to drop off its lobe and reclose the contacts. The overriding hand control mechanism comprises a rod 20 which is rotatable in the sleeve 13 and to which is fixed a locking plate 26 at one end and a cam 21 having two lobes 22, 23 at the other end. In the inoperative position shown, a projection 36 on a spring-biased latch 32, pivoted at 33, abuts the curved periphery of the locking plate 26 and a pin 35 carried by the latch is consequently held clear of the teeth of the star wheel 12. To open the contacts 18, 19 when they are in the closed position at shown, the locking plate 26 is moved clockwise by a knob (not shown) on a setting plate 40, through a lost-motion connection 31, 41, until the projection 36 on the latch engages in a notch 28 in the locking plate so that the pin 35 on the latch moves into the path of the teeth of the star wheel 12. Movement of the locking plate 26 also rotates the cam 21 so that the lobe 22 engages the tail-piece 24 on the contact spring 17 and opens the contacts. Subsequent anti-clockwise movement of the star wheel 12 by a tappet 11 causes a tooth of the star wheel to move the pin 35 outwards thus unlatching the locking plate 26 and allowing the hand control mechanism to be returned to the inoperative position by a spring 38 engaging a flat 39 on the rod 20. To close the contacts if they are open, the locking plate 26 is moved anti-clockwise by the knob until the projection 36 drops into the notch 29. Movement of the locking plate rotates the cam 21 until the lobe 23 engages the tail-piece 25 on the spring 16, thus closing the contacts. The hand control mechanism is returned to the inoperative position by the subsequent movement of the star wheel as described above. The hand control mechanism can also be returned to its inoperative position by manual rotation of the knob which causes a projection 42 on the setting plate 40 to move the pin 35 outwards.

Abstract: 823,404. Electric correspondence control systems. ESSOLDOMATIC Ltd. Oct. 10, 1957 [July 13, 1956], No. 21721/56. Class 40 (1). [Also in Group XL (b)] In a cinematograph projector, buckling of the film 1 due to heat is adapted to vary the amount of light from an auxiliary source S reflected on to a photo-transistor 6, thereby varying the value of positive voltage pulses produced by the rectifying action of the transistor 6 upon current derived from the secondary winding of a transformer T, the pulses being applied to the grid 7 of a gas-filled triode V to control the instant of striking of the valve V in each positive half-cycle of energization of its anode circuit by the secondary winding of the transformer T, the anode current pulses so produced in the valve V being passed through a winding 13 on a movable magnetic core 12 which by a mechanical linkage displaces the projector lens to adjust the forcus in accordance with the extent of film buckle. The winding 13 acts in opposition to a D.C. energized fixed coil 9. A winding 11 on the core 12 in series with the transistor 6 assists in stabilizing the operation of the apparatus. The grid 7 is biased in phase opposition to the voltage applied to the anode of the valve V by a connection on the secondary of the transformer T.

Title: A process of improving commercial aluminium
IPC: C22C21/00
Filed: 1922-08-17
Abstract: 211,027. Rosenhain, W., and Grogan, J. D. Aug. 17, 1922. Alloys.-A process for improving commercial aluminium containing silicon in solid solution consists in introducing into molten aluminium a small proportion of a metal such as calcium, barium, or beryllium, which will form with the silicon a compound insoluble in solid aluminium, so as to obtain aluminium of high electrical conductivity notwithstanding the presence of calcium and silicon. The calcium may be added to the aluminium in the form of an alloy of calcium and aluminium. Alternatively a suitable calcium compound may be reduced together with the usual aluminium compound by a known process for reducing the latter. For example in the electrolysis of alumina in a bath of molten cryolite, calcium salts such as calcium fluoride may be added to the bath in such proportion that a small quantity of calcium passes into the aluminium to combine with the silicon present.

The container 11 which may have two compartments separated by a partition 15, is supported on a platform 16 capable of vertical movement. The platform initially raises the container to the position of Fig. 1 and the plunger 10 feeds in a stack to one compartment. The container is then moved sideways along the platform 16 and a stack is fed to the second compartment. The platform lowers the container to the position of Fig. 3 and a further stack is fed into the second compartment. The container then moves horizontally so that a second stack may be fed to the first compartment. In an alternative embodiment, on uncompartmented container is filled by placing within it two stacks, one above the other. The platform 9 and end walls of the receptacle 8 may be pivoted to better accommodate filter tipped cigarettes, as described in Specification 890,272.

The coated thread 20 is cooled by passage through a cooling water bath 24, treated with a lubricant or drying agent, e.g. talcum powder, at 25 and wound on spool 26. When used for bonding together fabrics, the coated filament wound on a carrier may be rotatably mounted in an applicator having heating means adjacent its dispensing end so that the coated filament is adhered to the fabric where desired when dispensed from the applicator in a tacky condition, a second fabric being superimposed over the first and the fabrics then heated and pressed together along the line of the filament so that the thermoplastic adhesive is caused to flow and is absorbed into the fabrics.
