Abstract: 777,300. Drilling-machine details. CHICAGO PNEUMATIC TOOL CO. June 20, 1955 [July 7, 1954], No. 17737/55. Class 83 (3). A guide 13 for the drill steel 24 of a rockdrill 11 comprises an arm 16 pivoted on the front-end of the shell 12 along which the drill is fed, a slot 19 in the arm to guide the steel, and a latch 21 influenced by a spring 33, or other resilient means, into position over the slot and rotatable into or out of engaged position by sliding engagement with the steel. This engagement may be caused at the end of a drilling operation by contact between the drillhousing 11 and guide-fingers 43 on the arm, producing rotation of the arm and its supporting-spindle 22 into a horizontal position, the steel freeing itself from the slot by engaging an inclined surface 32 on the latch to rotate the latter about its fixing bolt 26 and uncover the slot. A diagonally-opposite, inclined-surface 31 on the latch is engaged by the steel and rotates the latch in the opposite direction to uncover the slot and allow entry of the steel when the arm is being raised into the vertical position. A spring-pressed pin 47 in the arm engages slots 48, 49 in a bracket 23 carrying the spindle 22 to hold the arm in vertical and horizontal positions. Alternatively, the arm may be operated by a fluid-pressure piston 57 connected by a piston-rod 58 to a crank 69 secured to the spindle 22.

Title: Control of electrical apparatus utilising power during preferred periods
IPC: G05D23/19
Filed: 1976-04-23
Abstract: 1491314 Control circuits for storage heaters LONDON ELECTRICITY BOARD L SHEPHERD and W G PEGRAM 23 April 1976 [29 April 1975] 17859/75 Heading H2H A circuit for controlling the supply of power during 'off-peak' periods to a load such as thermal storage apparatus comprises a counter operative at the start of the period to count signals at a frequency determined by a first adjustable analogue timing circuit until a predetermined count is reached whereupon the counter causes closure of a switch S1 to supply power to the load and simultaneously commences to count signals at a frequency determined by a second adjustable analogue timing circuit until a further predetermined count is reached whereupon the switch is opened to interrupt the supply of power to the load. At the start of the "off-peak" period, the counter in an integrated circuit 20 starts to count signals at a frequency determined by the first timing circuit including an adjustable resistor 23 and a capacitor 21. When the predetermined count is reached, an output at pin 9 of the circuit 20 switches off a transistor Tr3 which in turn switches on transistors Tr1 Tr2. A relay 10 closes the switch S1 to energize the load and simultaneously changes over a switch S2 so that the counter continues counting signals at a rate determined by a resistor 24. When the further predetermined count is reached, the output voltage at pin 4 of the circuit 20 deenergizes the relay to disconnect the load from the power supply. The resistors 23, 24 may be thermistors. In a modification, Fig. 3 (not shown), a diode senses the external temperature and controls the duration for which power is supplied to the load in dependence on the external temperature.

Attached to the conveyer section there is a bearing member 13, and a thrust member 14 which projects from the ram has an arcuate bearing surface 14a. Between the thrust member 14 and the bearing member 13 there is an arcuate bearing plate 12a secured to at least link 12. The bolt 17 extends through the bearing member 13, and trunnions 13a, 13b, on the member 13 engage in vertical slots formed by U brackets 20, 21. These brackets are secured to a flanged bracket 22 fastened to the conveyer section. The bolt 17 is received in a slotted hole 13c in the member 13. Connections as described make allowance for the increase and decrease of pitch distance of conveyer sections adapted to be advanced with a " snaking " action, thereby avoiding unsatisfactory reaction between the jacks and the conveyer sections. Referring to Figs. 1, 2, the permissible width of the gaps G-G7 is <SP>5</SP>/ 8  inch and the normal pitch distance of the sections is indicated at P-P1. With regard to pitch points P2-P5, the leading edges represented by points L-L3 of the conveyer sections progressively creep with a lead over the pitch points, the lead creeping to 2¢ inches. From the pitch point P5, the lead gradually decreases in relation to the leading edges represented by points L4-L8 of the sections 6-9. The section 10 is related normally to the pitch points P9, P10.

Abstract: 1,220,432. Metal wire guides. MORGARDSHAMMAR A.B. 9 April, 1969 [9 April, 1968], No. 18092/69. Heading B3W. The front and rear crop of hot-wire passing from a rolling mill to a reel 8 are severed by shears 4 and guided by switch guide 3 to toggle shears 6 for cutting up into lengths e.g. for samples. To retard the cut lengths moving from the mill at high speed 16 prevent their being damaged and to maintain their order of cutting a guide pipe 9 leads from the shears 6 substantially tangentially at 12 into a cylindrical or conical drum 10. The cut lengths are constrained by centrifugal force to follow a path around the inner surface of the drum, finally falling through an opening 13 on to a conveyer 14. In use, when a predetermined crop length has passed through the switch guide 3 in the full line position an impulse switches the guide to the broken line position and the shears 4 makes a clean cut through the wire. For identification of the cut lengths a spring 11 coats the crop portions nearest the clean cut with a metal oxide slurry. Two spray guns with different coloured sprays may be used for the front and rear crop respectively.

Abstract: 494,038. Flexible tubes ; braiding. SUPERFLEXIT, Ltd., and GRINT, W. H. June 29, 1937, No. 18107. [Class 74 (i)] [Also in Group XXVIII] Threads or wires 19 are braided on a stationary mandrel 5 in a braiding machine and a coating of viscous material is applied to the braided tube so as to produce a flexible tube reinforced by the threads or wires. The viscous material may be applied to the inside of the threads or wires through the mandrel and an annular groove 10 in an extension thereof or to the outside by a nozzle 13 or to both the inside and outside. The groove 10 or the nozzle 13 may be of helical form to prevent the formation of ridges in the hose due to twisting as the hose leaves the machine. Formers 11 and 17 determine the thickness of the internal and external coatings respectively. When the coating is applied either internally or externally it may pass through the braided threads or wires to form a coat on both sides of the tube. A tube of increased strength may consist of two or three layers of coated braiding. The viscous material may be dried by passing the tube through a drying chamber 18 or by supplying a drying medium to the inside of the tube through a nozzle 12. Suitable materials for the coating are aliphatic 'or aromatic vinyl resins or synthetic rubbers. Different materials may be supplied to the inside and outside of the hose. When polyvinyl alcohol is used for the coating a formaldehyde may serve as a drying medium. The braiding of the wires or threads 19 is effected by rows of shuttles 1, 2 which are rotated in opposite directions and traverse sinuous paths which intersect.
