Title: Safety closure caps
IPC: B65D50/04
Filed: 1981-06-10
Abstract: A safety closure cap consists of resilient material and is used to close the opening on a container. The opening has an annular bead and the closure cap has a plurality of projections 14 which engage the bead. The closure cap is provided with two handles 12 which are diametrically opposed to each other and which project above a top surface of the cap. When the handles are moved towards each other, the projections, which are hook-shaped, are released and the closure cap can be removed. To facilitate deformation, the rim 11 of the cap is weakened by slots 15, see Figure 6. A locking member 13, Figure 1, which must first be moved to the side or released if it is desired to remove the closure cap, is disposed between the two handles 12. The locking member can be constructed as a bar which can be swung away or removed as a releasable element 33 Figure 6. <IMAGE>

Title: Earthworking implement side plate wear member
IPC: E02F3/815
Filed: 1980-02-04
Abstract: Improved wear member (15) useful in protecting the bottom edge portion (14) of the sidewall (11, 12) of an earthworking member (10). Removable pins (33) may extend through the U-shaped bottom bight portion (25) of the wear member (15) and the bottom edge portion (14) of the sidewall member (11, 12). The pins (33) may be locked against axial displacement by locking rings (35) received in inwardly opposed recesses (34) of the legs (26, 29) of the bight portion (25). A heavy half arrow shaped wear member (16) may be secured to the frontedge of the sidewall member (11, 12) above the U-shaped bight bottom portion (25). This design has the advantages of being simple, economical of construction and allowing for fast replacement of the wear member (15).
Patent GB-2078513-A (GB)
Title: Escape equipment
IPC: A62B1/14
Filed: 1981-06-19
Abstract: A travelling clamp 10 comprises a frame 11 carrying a pair of jaws 12 and guide means 13 for guiding a radially resilient hose 19 between the jaws. By movement of handles 16, the jaws are moveable between an open position and a closed position. In the open position, a hose 19 can be introduced between the jaws 12, while in the closed position the jaws 12 secure the travelling clamp 10 to the line. When in the closed position, the jaws 12 of the travelling clamp 10 compress the line to an extent such that the weight of the clamp alone is not sufficient to let the clamp travel down the line. On the other hand, with the extra weight of a human being, the gap between the jaws is sufficient to allow the hose to pass up between the jaws, the clamp thus travelling gradually down the hose with progressive radial compression and relaxation of the hose or line. <IMAGE>
Patent GB-2083299-A (GB)
Title: Stored charge inverter circuit
IPC: H02M7/538
Filed: 1981-08-12
Abstract: An inverter circuit having a pair of transistors Q1, Q2 connected to alternately and repetitively apply electrical energy to an inductive load 21. Short duration turn-off pulses 37, 38 are alternately applied to the transistors, and means 26, 28 are connected so that when each transistor is turned off, flyback current induced in the load is applied to the other transistor to create a stored charge for turning it on and keeping it on until it receives its next turn-off pulse. Thus, no externally supplied repetitive forward base current is required. Alternatively the turn off pulses are not provided and each transistor remains conductive until its stored charge drains off sufficiently so that the transistor automatically turns off and the circuit is then free running. Instead of the half-bridge inverter circuit it can be of full-bridge or push-pull type. <IMAGE>

Title: Lubrication of a bearing assembly
Inventor: BRIGGS JACK
IPC: F16C33/66
Filed: 1981-12-11
Abstract: A bearing assembly 34 separates two co-rotating shafts (8, 16). Both races (34, 36) rotate, as does the surrounding structure (shaft 16). An annular oil catcher (70) is fixed to the outer race (36) to catch oil which has traversed the rolling elements (40). Oil catcher 70 is an integral member which has no joints which are exposed to oil which is being acted upon by centrifugal force. Oil is piped from the oil catcher to a space (52) bounded by a non rotary casing (54) which absorbs the kinetic energy in the oil. <IMAGE>

Title: Battery plate grids
Inventor: PEARSON ERNEST JAMES
IPC: H01M4/74
Filed: 1982-04-15
Abstract: This invention is a method of making a battery plate grid from a continuous sheet of expanded metal with a central unexpanded reservation 11 with slitted and expanded metal in portions of the grid 12 and 13 on either side of it.

Title: Brush making machines
Inventor: MUSCHELKNAUTZ KLAUS
IPC: A46D3/08
Filed: 1982-11-22
Abstract: A brush-making machine has a twin filling machine with two filling tools or two individual filling machines provided in the vicinity of a transporting device. A transfer apparatus 10, provided for delivering the filled brushes 9 to the transporting device 11, is arranged and constructed so as to reduce the lateral spacing between the filled brushes 9. For example, the brush gripping means 14 arranged side by side on the transfer apparatus 10 are mounted so as to be movable relative to one another into the receiving position or delivery position. In the case of individual filling machines (not shown), the fact that these machines are arranged side by side at a spacing from one another automatically results in a large spacing between the individual brush bodies, and this is also reduced by the transfer apparatus according to the invention to give the required small lateral spacing between brushes which are to be machined simultaneously. <IMAGE>

Title: Capacitive position transducers
Inventor: SIDEY ROGER CHARLES HEY
IPC: G01D5/241
Filed: 1983-02-07
Abstract: A method for measuring angular (Fig. 1) or linear position by means of a capacitive or electrostatic device where the positional information is conveyed by the relative phase of the output signal of the measuring device to that of a system of associated energizing supplies. The capacitance between an array of energized electrodes H on a stationary element E, and a sense array D on a movable element B is maintained substantially constant. By this means, and by the utilization of energizing sources that apply signals of small electrical phase difference to adjacent electrodes on the stationary element, a close approximation to a linear measurement characteristic is achieved. <IMAGE>

Title: Discharging pulverous material from containers
Inventor: AMIRTE ANDREW BRYSON
IPC: B65D88/70
Filed: 1983-11-10
Abstract: A container for pulverous materials has a discharge hopper fitted with air inlets serving to effect fluidisation of the contents to assist gravity discharge. Each inlet comprises a stainless steel air-box body 20 with a threaded spigot 21 and nuts 22 by which the body may be secured to the wall of a hopper in a manner which affords simple removal and replacement. The spigot 21 couples with an air supply at 23 whereby the interior of body 20 may be fed with air. The open or apertured 20a face of the body is normally closed by means of a rubber diaphragm 24 which is secured by means of a back plate 25 and nut 26. The diaphragm comprises a central core 24a and a peripheral annular skirt 24b. On application of air pressure through spigot 21 in the direction of arrows A the diaphragm skirt 24b is caused to lift from the upper surface of body 20 as illustrated, thus providing a distributed air flow around the diaphragm. With this arrangement the product in the hopper is unable to contaminate the air pipes as the diaphragm closes the passageways as soon as pressure is relieved. <IMAGE>

Title: A Method of Determining the Oxidizing Activity of a Biological Liquid, and a Mammalian Lens- derived Reagent for use in the Method
Inventor: TESTA MICHELE
IPC: A61K35/44
Filed: 1984-02-24
Abstract: A reagent based on homogenized mammal lenses which have been dialysed and optionally freeze-dried for preservation is used for exact, reproducible measurement of the oxidizing activity of a biological liquid more particularly serum. A known method is used to test two samples of the biological liquid treated with the reagent, one sample having been incubated at from 10 DEG C to 40 DEG C for 20 to 4 hours and the other sample not having been incubated, the oxidising activity of the liquid being determined from the difference in the two test results. A reduction in oxidizing activity following administration of a drug for treatment of cataract indicates that the drug is effective.
