Title: Improvements in or relating to electrical apparatus for controlling the detonation of explosive charges and including improved means comprising a momentary contact electric switching means for controlling the detonating circuit
IPC: F42D1/045
Filed: 1932-08-04
Abstract: 405,329. Momentary-contact switches; plug couplings combined with switches. GENERAL ELECTRIC CO., Ltd., and RICHARDS, S. W., Magnet House, Kingsway, London. Aug. 4, 1932, No. 21879. [Class 38 (v).] A momentary-contact switch for use in detonating explosive charges is mounted in an upper compartment of a battery case one pole of the battery being connected to one of a pair of contact springs 16 the other contact being connected by a lead 28 to a metal bushing 25. The other pole of the battery is connected to a single contact spring 17. An operating rod 20 slides in an insulating bushing 21 and in a bracket 18 and is biassed towards the left by a spring 24 engaging a pin 23 on the rod 20. A plate 30 is pivoted on the pin 23 and carries an arm 29 having an insulating tip 32 for engaging the contact springs 16 and a contact (not shown) for engaging the contact 17. A catch plate 36 biassed to the left by a spring 34 has a catch 40 engaging the pin 23, a pin 37 engaging a curved slot 31 in plate 30, and a pin 38 sliding in a slot 39 in mounting plate 19. The conductors from the detonator are clipped on to springs 51 on a detachable key 50 and thus connected respectively to relatively insulated concentric conductors 53, 52. To make a detonation the key is inserted through metal bushing 25 so that the outer conductor 53 which is spring-mounted makes contact with the bushing and hence to one of the contact springs 16. The central conductor 52 makes contact with the operating rod 20 and moves it to the right against the spring 24. The pin 23 thus carries along with it the plate 30 and the catch plate 36 until pin 38 meets the end of slot 39. The plate 36 is then tilted anti-clockwise thus releasing the catch 40 from pin 23. When the plate 36 starts to return due to spring 34 the pin 37 engages the slot 31 to tilt the plate 30 causing the arm 29 to close the contacts 16, 17 momentarily. The circuit from the battery is thus made through contacts 16, bushing 25, conductor 53 to the detonator and from the other pole of the battery through contact 17, arm 29, rod 20 and conductor 52. The return of the latch plate 36 is retarded by means of a rack 41 carried by the plate engaging pins 48 on a pivoted oscillating mass 43 the selection of which determines the duration of the momentary contact.

Title: Improvements in or relating to collet chucks
IPC: B23B31/20
Filed: 1946-07-25
Abstract: 625,578. Chucks. SMART & BROWN (ENGINEERS), Ltd., and LORD, W. July 25, 1946, No. 22174. [Class 83 (iii)] A hollow spindle chuck is operated by a member 7 which engages a sleeve 3 carrying a collet 1 and is adapted, after a period of lost-motion, to move the sleeve positively to the release position, if the resiliency of the collet has failed to shift the sleeve. The operating member or collar 7 is splined to the spindle 2 and is axially movable by a ring 14 mounted on trunnions 14a on a ring 12 on a handle 15 which is pivoted at 13. Rearward movement of the collar 7 causes an internal tapered surface 7a to pivot levers 5 on a member 10 secured to the spindle, and the levers bear on a hardened disc 6 on a cap 11 secured to the sleeve 3, so that the sleeve is moved rearwardly and causes the collet to grip the work. On forward movement of the collar, the resiliency of the collet draws the sleeve forward but, should this fail to happen, a shoulder 8 engages a ring 9 on the cap 11 as the collar nears the end of its movement and positively moves the sleeve to the release position. The collet is screwed to the sleeve and can be initially adjusted by rotating the cap 11 while the spindle and therefore the collet are stationary; domed spring-pressed plungers 16 fitted on the member 10 engage axial grooves 20 in a ring 18 on the cap 11 and hold the cap in the adjusted position relative to the spindle.

Title: A fabric diaphragm for electrolysers
IPC: C25B13/00
Filed: 1962-06-08
Abstract: 934,035. Diaphragms for electrolytic cells. MASCHINENFABRIK OERLIKON. June 8, 1962 [July 26, 1961], No. 22356/62. Class 41. Diaphragms for electrolytic cells, e.g. for generating oxygen and hydrogen, are made impervious to gas at the top when wet but pervious to electric current, and of open weave fabric at the lower part. An anode 1 and a cathode 2 are mounted on either side of a woven asbestos diaphragm 3, densely woven at the base 3<SP>11</SP> to give mechanical strength, and at the top 3<SP>1</SP> extending downwards for 10- 15 % of the height of the diaphragm. By this means the oxygen and hydrogen gases given off vigorously at the top level of the electrolyte are prevented from mixing through the diaphragm and the explosion risk is lessened. The fabric is closely woven at the top to give 100% masking to light but in the centre the threads may be spaced apart by the amount of twice the thread diameter. The threads may be reinforced with nickel wire or plastic thread. Alternatively, the diaphragm may be of a thin permeable fabric with reinforcing strip or strips applied at the top.

[Class 51 (i).] Lump or granular fuel fed from a hopper 2 on to a travelling or other mechanical grate 1 is loosened or agitated by fixed or movable means such as chains 14, Fig. 7, fixed to the regulating slide 15 and passing out through the fuel to the front of the furnace, and a channel 22 supplies a blast of air stronger than the rest of the undergrate blast to the point of agitation so that the fuel is re-arranged with the smaller pieces at the top. A blower 16 supplies air through pipes 17 to the ordinary undergrate blast channels 18 and through a pipe 19 to an additional blower 20 which supplies the stronger blast to the channel 22. The blower 20 may be replaced by a steam injector in the pipe 19. A pulsating air current may be supplied to the channel 22 by a blower 20 with few blades or by a pulsating injector. The chains 14 may be replaced by fixed or movable rows of hooks 4, Fig. 2, on rods 3 or a single row, which may be reciprocated, or by screws 7, Fig. 4, which may be positively rotated or freely mounted in bearings 8 so as to be rotated by the moving fuel. Other modifications of the loosening means are fixed ploughshares, downwardly directed hooks pivoted to the wall of the hopper and a blade wheel either positively driven or turned by the fuel. The hopper 2 may be divided so as to supply successive layers of slag, main fuel and ignition fuel. Unburnt portions of waste fuel may be returned to the grate, and the gases from the rear end of the grate may be sucked off and mixed with the fresh combustion air. The hooks 4 may have flattened portions arranged to sweep over a thin lowest layer of fuel without agitating it.

Title: A procedure and device for the direct transposition of raised configurations and creation of composite patterns upon plane surfaces
IPC: B44B3/00
Filed: 1965-05-28
Abstract: 1,035,750. Pantographic apparatus. A. STADERINI. May 28, 1965, No. 22864/65. Heading B6P. [Also in Division G1] A device for representing a three-dimensional body, such as a coin or medal, in two dimensions comprises a pair of synchronously rotating discs 1, 2 and a pantograph arrangement mounted on lead screw means for traversing the pantograph across the discs. Vertical movements of the pantograph feeler 42 as it senses the relief configurations of an object a are translated into horizontal movements of the tracer 33. The vertical movement of the feeler 42 and the arm 41 is translated into pivotal movement of arm 40 (having a counterbalance 44) about a pivot point 43, Fig. 2 (not shown), at the junction of arm 39 with arm 40. Arm 39 and upstanding pin 38 therefore rotate about the longitudinal axis of the arm 39. Movement of the pin 38 is translated into horizontal oscillatory motions of arm 35 about pivot point 29, which arm 35 is attached to the frame 30. Pivoted to the frame 30 on a horizontal axis 31 is the arm 32 supporting the tracer 33. An adjustable counterbalance 34 adjusts the applied pressure at the tracer 33. The object a can be positioned on the disc 1 having regard for cams 49 and 50 around the rim thereof. These cams operate a switch 51 which in turn causes the discs to accelerate during that period when the feeler 42 is not sensing the object a. A cam 52 on the common drive shaft 3 for the discs, operates through levers, Fig. 3 (not shown), to raise the pantograph out of working contact with the discs during periods of acceleration. In a modification, Figs. 2 and 7 (not shown), the feeler 42 is vertically reciprocated by tappet means from a cam disc 69 driven through gears 70, 71 from the drive shaft 3. The cam disc 69 which comprises a wheel provided with one or more concentric arrays of holes 75, may have its working profile varied by selecting the number and position of rotatable rolls 77 mounted on pins 76 in the holes 75. Various patterns may be traced on the disc 2 with the modified arrangement.
