Title: Prevention of destruction of machine elements
IPC: F16P7/02
Filed: 1979-10-04
Abstract: A method of preventing the destruction of machine elements and a machine provided with means for such prevention is particularly applicable to shafts of printing machines, rotary folders and so forth. Precautions are to be taken against the destruction of machine elements especially in the case of breakdowns. In order that repairs can be avoided and machine standstill times reduced, the machine is stopped at the onset of overloading of the machine elements without the product processed by the machine having to be observed optically or by similar means. Overloading is measured at a region of a bearing (7), the measurement result detected, compared with a predetermined value and a signal for stopping the machine is triggered on a given tolerance being exceeded. Deformable spacer members (8) are arranged between a wall bore of the machine and the bearing (7) and a measurement value pick-up (14) (electrical fine indicator), which is connected with a motor switch (19), is arranged in a spacer member (8') disposed in the direction of loading. The invention is applicable not only to shaft bearings of printing machines, but generally in machine construction. <IMAGE>

Patent GB-2034204-A (GB)
Title: Cyclone Dust Separator
IPC: B04C5/28
Filed: 1979-10-25
Abstract: A separator for separating particles of contaminate matter from gas, e.g. dust from air, is of the type in which the incoming contaminated gas is caused to swirl around the inside of one or more cyclone tubes (2), the purified gas being discharged via a vortex finder (8) within the or each cyclone tube. Hitherto the contaminated gas has entered the tube(s) tangentially to establish the desired swirl. In the separator of the invention means, preferably flat plates (10, 12), are provided in the space between the tube (2) and the vortex finder (8) to establish the swirl and hence the gas may be introduced axially enabling the tubes, in the case of a multi-tube separator, to be packed closer together within the separator body. <IMAGE>

Title: Air Compressor Equipment
IPC: F04B39/00
Filed: 1980-01-21
Abstract: An air compressor unit has a housing (10, 12) containing a resiliently mounted electric motor (32) and compressor (30), which draws air into the housing through inlets (23) via a tortuous passage (20) formed by sound absorbent baffles (22), and delivers the air externally of the housing through outlets (54, 56). The housing is made in two halves (10, 12), each comprising a rigid metal outer layer (14) and a thermally conductive, sound absorbing inner layer (16), e.g. of lead-filled rubber. Silencers (38, 40) are preferably fitted to the compressor, and may comprise air expansion chambers (78, 80 - Fig. 3 - not shown). In this way the production of noise is reduced and its escape from the housing is kept low, since the housing does not need any openings for the through flow of cooling air by convection. <IMAGE>

Patent GB-2047434-A (GB)
Title: Pressure relief valve
IPC: F15B11/044
Filed: 1980-03-25
Abstract: A hydraulic pressure relief circuit includes a main valve (14), a bleed flow orifice (18) to provide stability to the main valve, a pilot valve (20) having a differential area piston (30,32) and a damping orifice (46) in conjunction with an accumulator (44). System pressure is limited by opening the main valve and allowing fluid flow from the system back to tank. The main valve is controlled as a bleed flow servo wherein the pilot valve (20) meters the bleed flow from the bleed flow orifice (18) to tank, thereby controlling the opening of the main valve. Fluid flow through the damping orifice (46) in conjunction with the accumulator (44) acts on area (A1) of the pilot valve to provide damping forces acting on the pilot valve with both rising and falling system pressures, thereby limiting the maximum rate of pressure increase in the circuit (10). <IMAGE>

Title: Car parking apparatus
IPC: E04H6/06
Filed: 1980-05-27
Abstract: The invention relates to car parking apparatus of the type including a frame carrying a platform for a car which can be raised to enable another car to be parked underneath. Such apparatus has been proposed in which the platform can be raised and lowered while maintaining a substantially horizontal orientation. While it has been quite satisfactory it has been difficult to ensure smooth operation and there is a need for such apparatus which will perform smoothly and reliably with the complete safety that is required. According to the present invention the platform (2) is raised and lowered on a pair of two stage piston cylinder mechanisms (32) adjacent upright frame members (10) on either side of the platform. Preferably the platform (2) is supported on a carriage (4) which itself has upstanding members parallel to the frame members (10). The horizontal orientation of the platform (2) is maintained in the preferred embodiment by vertically spaced rollers on the upstanding carriage members running in tracks in the frame members. <IMAGE>

Patent GB-2061117-A (GB)
Title: Respirator mask
IPC: A62B9/02
Filed: 1980-10-07
Abstract: A respirator mask has a valve 11 for admitting breathing gas and a pressure chamber 8 between a breathing space 9 in front of the user's respiratory organs and the surrounding atmosphere. The purpose is to set up a gauge pressure in front of the user's respiratory organs during the inhalation phase as well as during the exhalation phase. Pressure chamber 8 is defined by two dish-shaped ports 12, 13 (port 12 being connected by holes 14 to space 9) and by a diaphragm 7. Port 13 is forced downwards by a spring 19. When the user inhales, pressure chamber 8 moves downward under the action of spring 19 and diaphragm 7 and pivots an arm 28 which causes the valve 11 to open. When the user exhales, pressure chamber 8 moves upwards and closes valve 11, port 12 abuts against flange 18, and port 13 is forced further upwards against spring 19 to allow gas to escape to the outside. A detent unit 31 may be present to push pressure chamber 8 upwards and keep valve 11 closed. <IMAGE>
