Title: Improvements in or relating to vehicle parking installations
IPC: E04H6/36
Filed: 1959-09-24
Abstract: 971,330. Mechanical garages. G. R. F. NUTTALL, and T. E. FOULKES. Dec. 23, 1960 [Sept. 24, 1959], No. 32464/59. Heading B8E. A car park consists of at least one row of movable platforms, the platforms of each row being releasably coupled together and one platform in each row being a motor-driven master platform. Vehicles are driven on to vacant platforms in a direction transverse to the length of the row or rows, there being a plurality of entry positions arranged side-by-side in a line parallel to the row or rows with, at each entry position, signal means permitting or forbidding entry and control means for uncoupling the platforms at points in the rows in line with such entry position and also for energizing the motors of the master platforms of a selected row or rows. In Fig. 1, there are six rows 1 to 6 and the entry positions are adjacent the platforms in row 6. At each entry the signal means is a semaphore arm 24 mounted on a post 23 and the control means are operated by push-buttons mounted on the post 23. Each platform comprises two wheel-supporting channels 25 and 26, Fig. 2, mounted on cross-struts 27 which carry trolley wheels 29 and 30, Fig. 4, running on rails 31, 30a respectively. The master platform, preferably an end platform, of each row is connected by a belt 34, Fig. 2, to a fixed drive motor (not shown) and each platform carries an hydraulically operated hooked latch 35 normally securing it to the next platform. To move the platforms, the control means at any entry can be operated to break the latches in line with that entry and to energize the motors for leftward or rightward movement. Movement is, however, only possible if all the signals are set at " stop," since the power supply to all the motors includes an isolating switch which is arranged to open automatically whenever any of the signals is set to " go." In Fig. 11, each of two separate rows of movable platforms i has its direction of entry at about 75 degrees to the line of the row and a guard door n is provided to bar access to that space at the end of a row into and from which the master platform is moved. On the side of each row i remote from the entries thereto is a row of fixed platforms j. The system may be multistorey, communication between floors being by way of a lift m.

[Class 87 (ii)] A foot and calf last of a vulcanising mould for making high rubber boots is divided into separate portions 1, 11, Fig. 1, in a plane such that by relative movement of the portions, the foot of the last is shortened and the periphery of the calf is reduced. When the portion 11 is shifted upwards as indicated in dotted lines in Fig. 1, the boot becomes detached from the last and is then pulled off by hand. The portions 1, 11 are arranged on a guide 21 housing a spring-loaded bolt 3 which at one end connects the stationary portion 1 with the guide 21 and at the other end abuts against the movable last portion 11. A toothed rack at the inner side of the portion 1<SP>1</SP> meshes with a pinion 4 which in turn meshes with the external rack teeth of an internally screw-threaded nut 5 secured against turning by a feather 6.. The nut 5 engages a screw-threaded spindle 8 which carries at its lower end a pinion 7 in mesh with another pinion 9. The last is carried by swivelling arms 16, 17, Fig. 4 (not shown), for inserting it into the vulcanising mould and withdrawing it to the position for removal of the boot. After vulcanisation and opening of the mould the last is brought to this position when the pinion 9 automatically engages a driving member 10, Fig. 3 which is set in motion and thus the last portion 11 is shifted upwards. The movable last portion 11 may be provided with a tiltable tip 19, Fig. 1. Two lasts may be provided so that while one is in the mould, the other is in the boot removal position.

Title: Improvements in vacuum valves for train control systems
IPC: B60T13/46
Filed: 1921-12-05
Abstract: 197,350. Regan, J. B. Dec. 5, 1921. Fluid-pressure.-In an electrically - controlled venting valve for vacuum brakes adapted to give a service application, an attempt to restore the vacuum while the valve is operative results in the opening of an additional venting valve. Fig. 1 shows the parts in the operative position. Normally the chamber 15 is open to the vacuum reservoir by way of the solenoid actuated valve 9 and passage 12, and the chamber 17 being open to atmosphere at 18, the diaphragm 16 holds the valve 20 in the upper position in which the chamber 26 is connected to the train-pipe which is connected at 23. The chamber 29 beneath the diaphragm 27 is connected at 28 to another branch of the train-pipe leading directly to the driver's valve or it may be connected to the same branch as the connection 23. The valve 32, connected to the diaphragm 27 and controlling port 36 to the atmosphere, is thus held closed by the spring 34. If the solenoid is de-energized the valve 9 is closed and the valve 8 opened to vent the chamber 15 to atmosphere, thereby depressing the diaphragm 16 so that the train-pipe is vented through the openings 18 which are sufficient only to admit of a service application of the brakes. The valve 20 in its lower position also closes the chamber 26 which thus remains at the original train-pipe pressure. If the driver as by putting into operation the large ejector attempts to restore the vacuum and release the brakes, the chamber 29 being still connected to the train-pipe, the diaphragm 27 will be depressed to open the valve 32 so as to connect the train-pipe to atmosphere through the port 36 when the vacuum in the chamber 29 exceeds that in the chamber 26.

Abstract: 1465518 Cathode-ray tube circuits AMERICAN OPTICAL CORP 24 July 1974 [24 July 1973] 32725/74 Heading H4T Spurious deflections of the beam of a scanning charged particle microprobe apparatus, such as a scanning electron microscope, due to external electrical or magnetic fields is compensated by determining the magnitude of the spurious deflections at predetermined beam positions and then generating and supplying to the beam deflection means (in addition to the normal deflection signals) deflection signals which produce deflections of the same magnitude but of opposite sign to the spurious deflections. Fig. 1, shows the general arrangement in which the beam 14 of a field emission scanning electron microscope scans a specimen 16 in line raster fashion under the control of horizontal and vertical sweep waves 34H, 34V respectively, supplied to a stigmator 24 and also supplied to a display monitor cathode-ray tube 32 on which information concerning the specimen, derived via a scintillation detector 26 and photomultiplier 30, is displayed. A measure of the spurious deflections of beam 14, (deemed to be caused by local 60 Hz equipment) is obtained, in the case of spurious deflection in the horizontal direction, by arresting the vertical scan of the beam 14 so that monitor 32 now displays a single vertical line 52 (Fig. 4) which, in the absence of the spurious deflections would be a straight vertical line. It is stated that it is not necessary to compensate for each horizontal sweep of beam 14 compensation being sufficient if effected over 24 sweep groups SG1 ... SG24. The compensation required to "straighten" line 52 in terms of voltages from twenty-four potentiometers superimposed on the horizontal deflection of beams 14 is then determined a similar determination involving a further set of twenty-four potentiometers being made in respect of the spurious deflections in the vertical direction and the voltages from each potentiometer in each set, contained in function generators 36H, 36V, then being sequentially supplied (under the control of a circuit 36 supplied from the scan generators 34H, 34V) to horizontal and vertical deflection coils in stigmator 24. Details of the function generator 36H and 36V are given with reference to Figs. 2 and 3 (neither shown).
