Title: Improvements in or relating to sclerometer apparatus
IPC: G01N3/44
Filed: 1964-09-21
Abstract: 1,069,365. Schlerometers. S. IMAI. Sept. 21, 1964 [Sept. 20, 1963], No.38478/64. Heading G1S. A schlerometer apparatus for measuring the hardness of a specimen 16 comprises a platform 15 elevated by a niotor 10 and magnetic clutch 12, an indentation member 17 for engaging the specimen when it is placed in position on said platform, a rod 18 carrying said punch, means for supporting said rod and for resiliently loading said rod, a pivoted lever 21 engaged by a portion of said rod remote from said punch, and an indication assembly (Fig. 5) comprising a pivoted pointer 25 for sweeping over a graduated dial 24, the lever 21 and the pointer being connected so that movement of the lever causes rotation of the pointer. The apparatus also comprises lever switch means 28 actuable by displacement of the lever 21 into an extreme position thereof, a photo-electric cell switch unit (Fig. 6) mounted with respect to the indicator dial, and comprising a light source 30 and a photo-electric cell 31 spaced from said light source and mounted adjacent the zero graduation on said dial, a mask 29 pivotally mounted for rotation around said dial in synchronism with said pointer so that it passes between the light source and the photo-electric cell when the pointer is in registry with the zero graduation, a control circuit comprising the lever switch means 28 and the photo-electric cell switch, and relay means connected for actuation by said control circuit and adapted to de-energize and stop movement of the motor and clutch unit when the control circuit is actuated. When the test specimen is moved upwardly, it engages the indentation member 17 which is in turn moved upwardly against the action of a spring 20. The movement of the indentation member tilts a lever 21 causing the pointer 25 to rotate about its pivot, indicating the vertical displacement of the indentation member on the dial. As the indentation member 17 approaches its uppermost limit, the lever switch 28 is closed by contact with one end of the lever 21. The mask 29 is attached fixedly to the pointer 25 on the opposite  side of the dial plate 24 so that as soon as the  mask intercepts the light source 30 of the photoelectric cell switch the controlled circuit is closed provided the switch 28 is closed, this position of the pointer corresponding to the zero mark of the scale 27, the motor and clutch mechanism being thus stopped immediately. Thus at the uppermost extreme position of the indentation member 17 the pointer 25 will coincide exactly with the zero of the scale 27. A lever 41 is then released to add a further load to the indentation member, driving the member 17 deeper into the test specimen, the position of the pointer thus reached being a measure of the hardness of the specimen.

Title: Pressure fluid operated valves
IPC: F16K17/00
Filed: 1962-10-11
Abstract: 1,021,263. Brake valves. BERG AIRLECTRO PRODUCTS CO. Oct. 11, 1962 [Oct. 11, 1961], No. 38605/62. Headings F2F and F2V. A valve in which a shuttle 11 is slidable in a chamber A having ports 2 to 5 spaced apart in the direction of travel of the shuttle, has the shuttle normally held in a position wherein there is no communication between the ports but can be moved in response to the pressure of a fluid admitted to the chamber to place pairs of ports in communication. In the preferred embodiment, the valve is employed in the fluid-operated brake system of a tractor and trailer to protect the system of the tractor against loss of air pressure due to leaks or broken lines in the trailer air system. The ports 2 and 4 are connected to the emergency brake systems and the ports 3 and 5 to the service brake systems of the tractor and trailer, respectively. When the system control valve is of the " vented " type, fluid first enters at inlet 7 and flows through grooves 47 into the port 4 until the trailer emergency system has been charged and the pressure at the inlet 7 reaches a value of between 35 and 40 p.s.i. to place the pairs of ports 3 and 5 and 2 and 4 in communication with each other through grooves in the outer surface of the shuttle. When a pressure of over 60 p.s.i. has been attained the shuttle abuts the right-hand end of the chamber A. If the system control valve is placed in emergency position either manually or automatically through a fall in emergency or tank pressure, the shuttle is moved to the left by a spring 15 to isolate the tractor and trailer braking systems, the port 4 remaining in communication with the inlet 7 so that diminution of pressure in the trailer emergency line will cause a relay valve to apply full pressure to the trailer brakes. An inlet 6, which may be plugged when not in use, is coupled to the system control valve when it is of the "non-vented" " type. Fluid flowing through the inlet 6 does not leave the valve but causes movement of the shuttle 11 to the left against a spring 16 to place the tractor and trailer systems in communication. The grooves 33, 35 and 41, 43 in the outer surface of the shuttle may have alternately varying lengths and may or may not have parallel sidewalls, those grooves aligned generally with the ports having parallel sidewalls while the others have not. Retainers 25 for the springs 15, 16 may have slotted or apertured walls.

Abstract: 949, 215. Linear dimension gauges; measuring strip thickness electrically. DAVY & UNITED ENGINEERING CO. Ltd. Oct. 25,1960 [Nov.18, 1959], No. 39093/59. Headings G1M and G1N. The thickness of moving hot strip 23 is gauged by rollers 11,12 carried on rotatable shafts 13,14 mounted in bearings in pivoted tubes 19, 20. The inner ends of the shafts 13,14 are mounted in bearings 26, 25 between which is mounted a telemetering device 24, the signals from which are transmitted to a remote indicator or recorder having a long time constant and so not responding to high frequency variations in the signals. A suitable device is stated to be an inductance type transducer coupled to a damped moving coil meter. Since the shafts 13, 14 rotate they are heated uniformly by the strip 23, but even if they do tend to buckle the periodic variations caused by this buckling have no effect on the indicator or recorder and the mean distance between the shafts is measured. In another embodiment the rollers 11 are replaced by non- rotatable feelers and the shafts are rotated directly by a motor. The motors used for this purpose may be electric or pneumatic. In the latter case, air exhausted from them may be used to keep the interior of the device at a controlled temperature. In each embodiment pneumatic means are provided to separate the feelers for insertion of the work.

Title: Improvements in automatic control systems for tools carried, semi-carried or trailed by a tractor
IPC: A01B63/22
Filed: 1959-11-24
Abstract: 883,643. Tractor power lifts. SAME SOC. ACC. MOTORI ENDOTERMICI. Nov. 24, 1959 [Sept. 23, 1959], No. 39831/59. Class 79(1). In a tractor hydraulic power-lift mechanism wherein an implement may be automatically held at a predetermined position relative to the tractor, the pump for the hydraulic system is operated from the tractor engine independently of the tractor gears and is housed in a casing separate from the tractor gear casing and not in communication therewith. The hydraulic ram, control valve therefore, and pump are housed as a unit in the container which may be attached to the casing of the gear mechanism of the tractor. The tractor power lift linkage comprises the lower arms 5, which are pivoted at 6 to levers 7 attached at their lower ends to a rotatable shaft 8 and pivoted at their upper ends to rods 11. Each rod 11 can slide between washers 12 and 13, Fig. 2, separated by a spring 16 and abutment members 10 and 90 cause one or other of the washers to move with the rod according to -its direction of movement. The lower arms 5 are attached by links 17 to power lift arms 18 which are attached to a shaft 40 rotated through a lever 39 by a hydraulic ram 37 to which fluid under pressure may be supplied by the pump 20 driven by the tractor engine. The pump has two opposed pistons and has a delivery side and a suction side which may be connected selectively to the ram 37 by a valve 43 which is connected by linkages to hand levers 21 and 22. The valve 43 also has a position whereby both delivery and suction conduits are closed. The valve 43 is displaced by a lever 49 pivoted at 50; the hand lever 22 is connected to lever 49 through the rod 60 and the hand lever 21 is connected to 49 through rod 57 and bell crank lever 53, one arm of which carries a roller 55 which bears upon a cam surface 56 carried by levers 39. The lever 49 is also connected by links 62, 25, 24 to the rod 11. The hand lever 21 is used for direct control of the hydraulic power lift system, for raising and lowering the power lift arms; the hand lever 22 is used for obtaining a predetermined depth-for a given setting of the lever 22 the lift arms will descend until by action of the cam 56 and bell crank 53, the valve 43 is shut off. Automatic depth control of the implement is obtained through links 62, 25, 24, 23 dependent upon reciprocations of the rod 11, the bell crank lever 53 being moved to an inoperative position. In a modification, Fig. 3, the implement is partly supported by a wheel 71, the position of which relative to the implement is adjusted from the power-lift arm 18 through a flexible cable 73. In a further modification, Fig. 4, the implement is partly supported by wheels 80, 77 attached to a link-work connected to a hydraulic jack 79 actuation of which from the power lift arms determines their position relative to the implement.
