Title: Roof support assembly suitable for use in mines
Inventor: PAWLING FRANK
IPC: E21D23/20
Filed: 1965-09-30
Abstract: 1,112,647. Advancing mine roof supports. DOWTY MINING EQUIPMENT Ltd. Dec. 28, 1966 [Sept. 30, 1965], No. 41561/65. Heading F1P. A series of advanceable roof supports A, B ... each having pressure operated support props 1, an advancing jack 2 and a pressure operated prop release valve 4, each also has manually operated valves 5, 6 connected to a main supply line P and a return line R, whereby manipulation of the valves 5, 6 on one support e. g. A can cause in an adjacent support B, (a) prop release, (b) support advance, (c) prop setting and (d) the advance of a conveyer acting as a conveyer for the supports. In the neutral position of the manually operated valves 5, 6 of support A, lines 7, 8, 9, 12 are connected to the return line R and valve 4' maintains the props 1' in roof supporting condition. To release the props 1' from the roof, valve 6 is operated to cause pressurization of the line 12 and consequent operation of prop release valve 4', the fluid from the props 1' passing through line 9 and valve 5 to the return line R. Subsequent operation of the valve 5 pressurizes line 8 to cause contraction of the jack 2' and the advancement of the support B. With the valve 6 still in its open position i. e. holding valve 4' open the valve 5 is operated to pressurize line 9 and thus re-set the props 1' against the roof. Closing of the valve 6 allows the prop release valve 4' to close since fluid in line 12 drains away. With the support B now set against the roof, conveyer advance is caused by operating the valve 5 so as to pressurize the line 7 connected to the extending side of the advancing jack 2'.

Abstract: 1477430 Controlling printers INTERNATIONAL BUSINESS MACHINES CORP 10 Oct 1975 [11 Nov 1974] 41580/75 Heading G4H In printing, data from a computer is assembled into lines in a buffer 70, the data for each line including identification of the desired character height for that line. In Fig. 3, 8-bit character code bytes from the computer are converted into graphic code in table 72, compressed at 76 by dropping repetitions of like characters, and assembled into pages in buffer 78. 8-bit forms control bytes from the computer are routed to a buffer 79 which has a respective storage location corresponding to each line storage location in a page buffer 78. The 4th bit of each forms control byte selects one of two character heights for the associated line and the last 4 bits of the forms control byte define a channel number used in cooperation with an address register 80 for defining a number of lines to be skipped, a "black line" code being insetted in the page buffer 78 for each line to be skipped. The data leaving the page buffer is decompressed at 81, and minor modifications to a page may be introduced at 82. 64 character generator modules 74 are provided for each of 4 different fonts and are addressed via line buffers 83, 84, used alternately. The outputs from the character generator modules modulate a laser beam (132) scanned across an electrographi print drum (142) in a plurality of horizontal lines to form a line of print. The number of horizontal "slices" read out from the character generator modules to form a line of print is controlled by the forms control byte for that line, which sets the starting and end values of a scan line select counter 148. For 6 lines per inch, counter 148 starts from zero and ends at 24, for 8 lines per inch, it starts at 4 and ends at 22.

Filed: 1973-09-05
Abstract: 1448738 Magnetic tape player SHARP KK 5 Sept 1973 [5 Sept 1972] 41821/73 Heading G5R A magnetic tape record player has a first control means to select fast forward wind and fast rewind, and a second control means, Fig. 2, operative during fast wind and/or rewind to sense whether or not there is information recorded on the tape and to act on the first control means to discontinue fast winding or rewinding only when the second control means senses that there is no information recorded on a portion of the tape after it has first sensed that there is information recorded on a preceding portion of the tape. A sensing head 1, independent of the record/playback head, contacts the tape under fast forward and/or rewind modes and a switch 12 energizes the circuitry in such modes. Signals from head 1 pass through an amplifier 2 to a rectifying circuit 3 wherein a capacitor 26 is charged by such signals and when the charge on capacitor 26 reaches a predetermined level transistors 27, 28 in Schmitt circuit 4 turn ON and OFF respectively to charge capacitor 31 via diode 29. In this state transistor 32 is held off. If, once capacitor 31 is charged, head 1 senses no signals for longer than a predetermined time, capacitor 26 discharges, transistors 27, 28 turn OFF and ON respectively, transistor 32 turns ON and capacitor 31 discharges mainly via transistor 32, capacitor 39 and resistor 38 thereby charging capacitor 39 positively to a level to turn SCR 6 ON causing current supply to a coil 10 to move a rocker plate, associated with a push-button tape transport control, to shift the apparatus to the stop or playback mode. Unless the head 1 has previously sensed information on the tape 1, capactior 31 will not have been charged and thus will not be able to charge capacitor 39 to trigger SCR 6 whereby the circuit is inoperative if a completely blank tape is used. The blank area sensing circuit is also disabled on closure of a switch 14. A ring magnet 7, located for example on the supply reel hub, turns reed switch 8 on and off to produce square pulses which are differentiated in autostop circuit 9, the negative differentiated signals passing via diode 42 to normally maintain capacitor 39 negatively charged. When the supply reel hub stops at the tape end, capacitor 39 charges positively via resistor 44 to turn on SCR 6 and energize coil 10 to place the apparatus in the stop mode. If the pause mode is selected, a switch 13 is closed to disable both the autostop and blank area sensing circuits.

Title: Oil level maintaining means for the lubricating systems of internal combustion engines
IPC: F01M11/06
Filed: 1965-10-04
Abstract: 1,121,695. Lubricating; valves. S. z. MILLEDGE. 3 Jan., 1967 [4 Oct., 1965], No. 42033/65. Headings F2A and F2V. Oil in an engine sump is automatically maintained at a predetermined level by means of the fluctuating pressure in the induction manifold of an engine. An auxiliary reservoir is provided and is constructed in two parts, a lower part containing oil and an upper part forming a suction dome; the parts being separated by a flexible diaphragm or by bellows. In an embodiment, a reservoir 1 is connected to a sump 3 of an internal combustion engine 2 by means of a pipe 4 and a tube 5, the latter being located in a dip-stick opening in a lug 6 on the side of a crank-case 7 and extending to the required oillevel 8. The reservoir 1 is also connected, via a cover 12, to a manifold 10 of the engine by means of a pipe 9; the cover 12 also extends to form a valve-guide 14 for a valve 15. The latter makes a sealing engagement with an upper surface of either a rolling-diaphragm 13 or a bellows 13a, one of which is provided and has a lower portion clamped between the cover 12 and the body of the reservoir. The valve is urged into a closed position by means of a spring 19, having one end engaging a washer 20 which is mounted on a stem 16 of the valve by means of a retainer 21 and having the other end engaging a ring 18 which is attached to the reservoir. The upward movement of the valve 15 is limited when the diaphragm or bellows have been fully extended and engage protuberances 22 formed in the cover 12; thus allowing air to pass from the reservoir, through the valve 15, via grooves 17 in the stem 16, into the space above the diaphragm or bellows. In use, when the manifold pressure is low, the diaphragm or bellows will lift or expand so as to draw excess oil from the sump 3 into the reservoir 1, the opening of the valve 15 will then control the flow until the required oil-level is attained. When the manifold pressure rises as the engine speed increases, the valve closes and a quantity of oil is returned to the sump due to the volume of the reservoir decreasing when the diaphragm lowers or the bellows contract. Thus the oil-level in the sump 3 is maintained constant by being progressively topped-up from the reservoir 1. The cover 12 may be transparent and made of plastics material, an oil-level indicator 11 may be provided in the reservoir 1, an oil resistant plastics bag containing a resilient open-cell sponge may replace the diaphragm, baffles may be provided to prevent frothing, and an oil-trap may be provided between the manifold and the reservoir.
