Abstract: 813,630. Hand tools for treating turf. HARGREAVES & CO. Ltd., W. April, 16, 1956 [April 15, 1955], No. 10847/55. Class 6(2). A hand tool for raising and aerating turf comprises two circular plates 13 and 16, the plate 13 being fixed at the lower end of a shaft 10 and the plate 16 being rotatably mounted on the said shaft. The plates are spaced apart by a washer 17, and the plate 16 is prevented from moving axially along the shaft 10 by a collar 18 fixed to the shaft. The lower fixed plate 13 is provided with a set of six spikes 14 and slots 15, and the upper rotatable plate is provided with a further set of six spikes 20 positioned so as to pass through the slots 15 in the lower plate, the length of the spikes 20 being such that their lower tips are in the same plane as those of the spikes 14. In operation, the spikes are inserted into the turf by applying pressure on the handle 11 and then by applying simultaneously a torque and gentle lifting force to the handle, one set of spikes moves relative to the other so as to compress the turf between them and raise it to allow the entry of air below the turf mat. The tool may be modified by using spikes of staple-like shape, as at 14a and 20a in Fig. 5, and by making the lower plate of smaller diameter than the upper one so that it is not necessary for the spikes 20a to pass through slots in the lower plate, and consequently there is no limit to the possible relative angular movement between the plates.

Filed: 1975-03-17
Abstract: 1491059 Logic voltage-conversion interface INTERNATIONAL BUSINESS MACHINES CORP 17 March 1975 [3 May 1974] 10954/75 Heading H3T A voltage level conversion circuit has an input circuit branch comprising a bipolar transistor T1 with input signals applied to its base and a load element P2, an output circuit branch comprising a complementary FET inverter P1, N2 with the gate electrodes connected to the collector of the bipolar transistor T 1, both branches being connected to a common variable-current sink N 1 which is responsive to the potential on the collector of the bipolar transistor Tl to control the current it will sink. As shown the two branches may be connected to a common supply terminal V3, they may also be connected to two different supplies (V5, V3, Fig 3, not shown). Preferably the current sink FETN, and the FET of the inverter having the same polarity N2 have a transconductance greater than the other FET OF the inverter P1, produced by a high gatewidth to length ratio. With T 1 off, N 1 and N2 hold the output terminal C at ground level. As T 1 is turned ON, N 1 provides a low resistance path for T 1 to ground, the current raises the potential of node E which temporarily is at a higher potential than node C. Current flows through N2 in a feed forward effect and speeds up the rise time of the waveform at C. Simultaneously with Tl going ON node B is pulled down and this change turns N2 off, P 1 ON and limits the current flow in N1.

Title: Improvements in the design and construction of latches for vehicles
IPC: E05B63/20
Filed: 1919-05-06
Abstract: 151,042. Sutcliffe, G. W. May 6, 1919. Latches, sliding.-The arrangement described in Specification 21343/13 for holding a latch from being forced back by direct pressure is applied to a sliding latch, which is blocked when shot, as before, by the links 11, 14, and the face 17 of a fixed fence 15. When the door is opened, the latch is held at half-cock by a slam-bolt against the impulsion of a spiral spring upon the handle spindle. If the slam-bolt should accidentally be tripped, a lever mounted upon the main spindle engages the door-post and removes the block before the latch strikes. This lever may carry the inside handle, to which a guard may be fitted. A member 5 having a projection 6 engaging the bolt 2 is operated by a pin-and-slot connexion 7, 8 from the follower 9, so as first to carry the blocking-strut 14 out of engagement with the face 17 of the fence 15, and then to move back the bolt while the part 14 moves along the surface 16 of the fence. When the main bolt 2 is withdrawn, it is held back by the engagement of pallets 18, 19, upon the follower 9 and upon a spring bolt 20, but is released upon slamming the door, and fully shot bv a spiral spring upon the handlespindle 1. The strut 14 at the same time comes into position to bear against the part 17 of the fence 15, and prevents the bolt from being forced back. Should the pawl-bolt 20 become tripped while the door is open, the bolt will be fully shot and blocked. To allow the door to be thrown to, even in this case, a lever 32, Fig. F, secured to the main spindle 1, and carrying, if desired, a finger-piece 34 to serve as an inside handle, is arranged to project from the edge of the door in such a way that it is pressed back by contact with the post, and turns the spindle sufficiently far to remove the block, and draw the bolt into the latching position. In connexion with the inside handle 34, a pivoted guard 35 may be fitted which requires to be positively lifted before the handle can be moved. In one form of the slambolt 20, a screw stop 26, Fig. L, is fitted to the tail 30 of the bolt, but is accessible through a hole 27 in the nose of the bolt, so as to allow the spring pressure upon it to be adjusted. The nose of the main bolt is formed with a longitudinal slit to render it more elastic.
Patent GB-628813-A (GB)
Title: Improvements in devices for the separation of air or gas from a flowing liquid
IPC: B01D19/00
Filed: 1946-04-12
Abstract: <PICT:0628813/III/1> Relates to devices for the separation of a gas from a flowing liquid wherein the liquid enters an inlet chamber separated from the outlet chamber by a perforated partition, the inlet chamber containing a float connected to a gas extraction valve located at or in communication with the inlet chamber, the valve being operated by the liquid level in the inlet chamber through the valve.  According to the invention, the valve comprises a hollow cylindrical member 11 open at both ends and connected to the float 13, the valve being slidable in a guiding sleeve 30 and adapted to seat over a gas outlet orifice 8 in the upper part of the inlet chamber or a chamber above it in communication therewith.  In operation, liquid enters the chamber 4 and any gas in the liquid escapes through the float 13, a tubular member 14, past the valve 11 which is open as shown to the gas orifice 8.  Gas escaping to the liquid outlet chamber 5 passes through pipes 26 to the tubular member 14 and thence to the orifice 8.  When liquid passes the lower end of the member 14, the float rises and through a rod 12 causes the valve 11 to rise against its seating so closing the orifice 8.  Gas escaping from the liquid passes, as before, through the float and member 14, but as the member 11 is against the orifice 8 the gas accumulates and forces down the liquid level and hence the float and member 11 and gas can once more escape through the orifice.  The Specification as open to inspection under Sect 91 comprises also a device (see Fig. 1 (Cancelled)), wherein an inlet 17 has an extension 19 so that liquid is conveyed towards the top of the device in order that gas may be separated therefrom before passing out through outlet 18.  The tube 14 is interchangeable and can be varied in length for liquids of different specific gravity.  This subject-matter does not appear in the Specification as accepted.
