Title: Improvements in positioning devices
Inventor: PETRUCCI LUCIANO GIOVANNI DARI
IPC: G05D3/12
Filed: 1956-03-01
Abstract: 860,257. Selective control systems. BIRMINGHAM SMALL ARMS CO. Ltd. May 2, 1957 [March 1, 1956], No. 6403/56. Class 40 (1). A device for positioning a shaft consists of a contact drum rotating with the shaft and, engaging the drum, a series of spaced contacts 7-12, Fig. 1, one of which is energized by closure of an associated switch 13-18, a motor 23 in circuit with the switches serving to drive the drum until the circuit is interrupted by the alignment of an insulating segment 6 with the energized contact. When the motor is energized, a relay 25 connected in parallel with it, holds a locking-bolt 27 withdrawn but as soon as the selected position is reached, the bolt is allowed to project under the action of spring 31 to engage the corresponding gap 29 in a locking- plate 30. The switches 13-18 may be controlled by manual push-buttons or by a punched record sensing device, e.g. as described in Specification 799,299. The shaft 3 may have a crank and a connecting-rod to convert the rotation into linear movement. The conducting surface of the drum may be divided into two parts connected to a double-coil relay controlling a reversing switch. By this means the homing movement of the drum always takes the shorter path.

IPC: E21C35/23
Filed: 1973-02-09
Abstract: 1414917 Mining machines COAL INDUSTRY (PATENTS) LTD 6 Feb 1974 [9 Feb 1973] 6437/73 Heading E1F A rotary cutter head for a mineral mining machine has ventilating means for preventing a build-up of methane at the working face, comprising a nozzle 17 for directing fluid, e.g. water, along a guide 15, the discharge of the fluid inducing air flow along the guide to or from the working surface. In the embodiment of Fig. 5 in which air is drawn from the working face, the dust-laden air drawn along the guide 15 collides with a baffle 18. A proportion of the dust becomes entrapped with the fluid discharged from the nozzle 17 and is collected in the usual way, while the remaining dust and the air are extracted through a duct 33 to a location remote from the workface. In the case where the induced air is directed to the workface, Fig. 4 (not shown), the air is relatively dust-free and the provision of a baffle is not necessary. Further conduits 40 and airinducing fluid-discharge nozzles 42 may be provided on the helical loading vanes 5. The fluid discharged from the nozzles is fed from a distributor 22, the fluid from the distributor being also led through conduits 26 to dust-suppression nozzles in the cutters 4. A conical cover plate 29 is provided to protect the ventilating means from broken mineral, the air at the workface entering the cutter head through a peripheral gap X. The plate may be provided with apertures (60), Fig. 10 (not shown), shielded to prevent the entry of broken material.

Abstract: 199,100. Smith, J. A. Manners-. March 13,1922. Illumination, changing advertisements by controlling.-An advertising or display sign is provided with one or more sources of light, a translucent diffusing screen, and light-intercepting means so spaced from the screen that the position of the image on the screen depends on the position of the light source. The intercepting means may consist of flat or corrugated stencil plates, or letters &c. on a support, and may be movable. As shown in Fig. 3, lamps d are illuminated alternately by a switch e which may be a thermoflashing device. When the illumination is changed the indication on the screen b takes up a different position. The lamps may be of different colours and, in a further example, a third permanently lighted lamp is provided so that the edges of the letters change in colour when the illumination is altered. In a modification, Fig. 8, two lamps d are mounted so as to be rotated by a pulley g and as a result of their rotation the sign changes in colour and position. The apertures in the stencils may be masked by flanges in either direction and may be fitted with coloured translucent material such as silk. The stencil plate may be translucent and coloured or perforated or made of canvas &c. The screen may be arranged to represent the advertisement by opalescent spaces in a dark back-ground for daylight effects. Large signs may be illuminated in sections, each group of lamps being in a compartment. The signs may be cylindrical, the lamp and stencils being capable of rotary or axial movement. The Provisional Specification describes a modification in which a number of lamps are lighted in succession to give the sign the effect of more or less continuous movement.
