Title: Improvements in photo-electric alarm and like systems
Filed: 1936-07-20
Abstract: 478,366. Locking switches. NOWAK, K. July 20, 1936, No. 20117. Convention date, July 19, 1935. [Class 38 (v)] [Also in Group XL] Relates to photo - electric alarm or like systems, and consists in means for putting the system into operation comprising a single switch member, the manual actuation of which first switches on the source of light and then the relay and alarm or like circuit. A lamp which indicates when the system is operative is also preferably switched on in the end position of the switch member. In the installation shown, a selenium or like cell 1 is connected in series with the winding 2 of a closed-circuit relay to a potentiometer 3, to which current is supplied from terminals 4 when a switch 10 is closed, a lamp 11 which illuminates the cell being lit up at the same time. When the armature 5 of the relay drops it closes a circuit through an alarm 7 or other controlled device, provided that contacts 9 have been closed. The switch 10 and contacts 9, as well as contacts 15 in circuit with a tell-tale lamp 14, are all under the control of a single manually rotatable spindle 16. When this is rotated clockwise as shown in Fig. 1, (anticlockwise as seen in Fig. 4), an arm 12 thereon first effects closure of the switch 10 by engagement with a lever 17, and subsequently cams 18 on the spindle depress springs 19 which carry the contacts 9, 15. By this means, closure of the circuits of the alarm 7 and of the indicator 14 can only occur after that of the lamp 11 and of the cell 1 has been closed. The springs 19 are preferably held in the circuit-closing position until the contact 10 is re-opened, so that the tell-tale lamp 14 does not go out until all the circuits are switched off. For this purpose, spring tongues 21 with insulating ends 22 are provided, to snap behind the springs 19 when these are depressed. The springs 19 are thus held down until, on reverse rotation of the spindle 16 to switch the system off, the arm 12 has shifted the lever 17 to open the switch 10. The lever 17, thus moved back to the position shown in Fig. 4, presses back the tongues 21, allowing the springs 19 to rise and open the contacts 9, 15. The end positions of the switch arm 12, as well as its intermediate positions, may be visually indicated by providing on the spindle 16 a disc, Fig. 7 (not shown), having an arcuate row of perforations, or a slot of varying width, through which may be seen a pilot lamp that is switched on in the primary circuit of the relay.

Title: Gas pressure blasting devices
Inventor: FILSTRUP EDWARD CHRISTIAN
IPC: E21C37/14
Filed: 1960-06-09
Abstract: 905,507. Fluid-pressure blasting cartridges. OLIN MATHIESON CHEMICAL CORPORATION. June 9, 1960, No. 20331/60. Class 9 (1). In a modification of the fluidpressure blasting cartridge described in Specification 901,089, a link 26 pivoted on the sleeve valve 12 is surrounded by a spring 24 and hinged to a link 28 rotatable about an axle 30 mounted in a spring cage 31, Fig. 3, the cage being held in position by a spring 32. Housed in the cage is a spring 37 extending between a pin 38 in a slot 39 and a pin 40 on the link 28 and tending to turn the link counter-clockwise, this movement being arrested by a boss 49. As gas is fed into the main body 13, the pressure on the sleeve valve 12 and its follower 14 produces a thrust in the link 26, which at first tends to turn the link 28 counter-clockwise, and is communicated through the boss 49 to the cage 31 to thrust the latter against its spring 32. As the pressure is increased and equalizes in the head, there is a counter-thrust produced on the link 28 through an adjustable stop 41, which eventually rotates the link 28 clockwise, breaking the toggle 26, 28 and allowing the valve to uncover the ports 10. After venting of the cartridge, the springs 24, 32, 37 return the associated parts to their initial positions. The venting pressure can be varied by altering the strength of the springs, adjusting the stop 41, introducing additional shims 34 between spring 32 and the end plug 36 or by moving the plug 36.

Filed: 1918-12-13
Abstract: 130,259. Frankinet, J. Dec. 13, 1918. Bevelling.-Relates to a machine for bevelling oval pieces of sheet glass &c. The rotating work is so mounted that it can be presented at the required angle to the grinding or polishing wheel, and is given an ecentric motion relatively to the chuck mandrel to ensure that, throughout each entire revolution, the elliptical periphery of the glass is kept correctly in contact with the grinding-wheel; also, during each rotation, the speed is varied, being accelerated whilst the ends of the oval are being ground and retarded when the sides are in contact with the grinding-wheel. The grinding-wheel 5, Fig. 3, is mounted so as to be adjustable in two planes by means of screws 7, 8 and is driven through a pulley 10. For polishing, a counterbalance or spring arrangement at the end of the shaft 4 allows the disk to yield slightly in the axial direction. The work mandrel 19, Figs. 1 and 5, is carried on a sleeve 18 pivotally mounted on a split collar 16 adjustably fixed to a standard 35, the arrangement providing a universal adjustment for the work. The mandrel 19 is driven from pulleys 29, Fig. 5, through worm gearing 26, 27 and elliptical gearing 21, 22. The chuck 20 is not directly coupled to the mandrel, but is mounted on a plate 30, Figs 1 and 2A, which is traversed relatively to a plate 31 carried by the mandrel, by means of two tappets 32 engaging with a ring cam 33 adjustably secured with the correct degree of eccentricity relatively to the mandrel bv means of bolts 36 passing through slots 37 in a flange 34 on the sleeve 18. This ensures that, as the chuck rotates, the oval glass is always kept in correct contact with the grinding-disk. The glass is secured to the chuck 20 by suction supplied from a vacuum pump through a nipple 40 and air passage 38.
