Title: Noise projection reduction in concrete formwork vibration - with detachable foam layer covering bulk material maintained during consolidation
IPC: E04G21/06
Filed: 1974-08-09
Abstract: The process is designed to reduce the radiation and projection of noise generated in the process of vibrating sheathings, forms and similar hollow bodies, which are shaken to consolidate concrete or other bulk matl. contained within them. A layer of easily removable, and/or automatically self-separating foamed matl. covers the open surface of the heaped bulk matl. and is kept in place during the process of consolidation. The foam may be derived from a matl. which has a chemical reaction with the consolidating matl. to produce a foam-releasing effect, pref. with the foam automatically disintegrating in the course of time.

Title: Grip studs for tyre - with plastic studs clipped to cable inside tread and protruding through conical holes
Inventor: KOSTER THEODORUS
IPC: B60C11/16
Filed: 1974-08-17
Abstract: The tyre tread is provided with a pattern of conical holes and with an array of cables which run round the circumference of the tyre and through the bottoms of the holes.

Title: Regulator for axial piston pumps - vol conveyed adjusted by input device controlling servo motor by control slider
Inventor: WAGENSEIL LUDWIG
IPC: F04B49/08
Filed: 1975-03-26
Abstract: Regulating installation for the adjustment of the volume being conveyed in axial piston pumps has the adjustment effected by an input device which controls a servo motor through a control slider, the servo motor being actuated by an auxiliary oil circuit. The control slider is harnessed between two pre-tensioned stabilising springs with the adjusting piston pre-tensioned against the stop on the control slider by the forceof one of the stabilising springs. The input link acts, in the case of a regulated input force, against the force of the stabilising spring pre-tensioning the adjusting piston either directly or indirectly onto the adjusting piston.

Title: Helicopter aerial vibration damping connection - has lever linkage with friction brake on pivot bushes alongside base
Inventor: ZUCKERMANN KARL-HEINZ ING GRAD
IPC: H01Q1/28
Filed: 1975-09-18
Abstract: A rod aerial on a helicopter is attached to a mounting base (4) by elastic support blocks (5). The aerial base frame (6) is also attached to a lever linkage (8, 9) to oppose a tilting moment on the aerial rod. The lever linkage has three pivot points (7, 10, 11). Two of the rotating pivot bushes are in contact with external spring loaded friction pads (15, 16). The braking action thus produced opposes any movement of the lever linkage. It is thus possible to absorb vibration of the tilting aerial rod (2).
Patent DE-2542788-A1 (DE)
Title: Vibratory drive unit - has elastic device with non-linear resistance characteristic to radial weight displacement
Inventor: BRANDER JAMES EDWARD
IPC: B06B1/16
Filed: 1975-09-23
Abstract: A supporting component is fixed to a secondary shaft so that they cannot rotate in relation to each other, and has a weight mounted on it so as to give to the complete assembly a certain amount of imbalance, due to being eccentric to the axis of rotation. Thus the weight is displaced radially outwards and increases the degree of imbalance. An elastic device normally thrusts the weight towards the axis of rotation, and this has a non-linear resistance characteristic to the radial displacement. The elastic device can incorporate a first spring (3) offering resistance to radial displacement over a first speed range, and a second one (4) coming into action at the end of this range to provide additional resistance over a further range.
Patent DE-2544337-A1 (DE)
Title: Motor regulator for control of winding in glass fibre prodn. - gives constant fibre tension and avoids fibre overlap
Inventor: SPENCER LOWELL C
IPC: H02P5/74
Filed: 1975-10-03
Abstract: A digitally-controlled motor regulator, giving complete control of winding in prodn. of glass fibres consists of a winding unit on which a band motor and a traverse motor are mounted, a SCR converter for the induction of the band motor, a transistor converter for the induction of the traverse motor, a brake control for braking the band motor and digital controls for generating the functions needed for operating the motor control system. To give constant tension on the glass fibres, the speed of the winding motor is programmed directly from the number of revs./minute, which is then converted automatically to the frequency. Control is largely automatic, and the operator needs only to start and stop the machine. Overlapping of the glass fibres is prevented by accurate, control of the speed of the spiral or traverse motor. The system includes a 'memory' so that if the system comes to a standstill before the ending of a complete cycle, it can be brought back accurately to the point at which breakdown occurred.

Title: Support of cryogenic storage tanks inside chamber - e.g. of a ship for transporting low boiling liquefied gases
Inventor: BRAEUTIGAM MAX ING GRAD
IPC: F17C3/00
Filed: 1976-02-07
Abstract: The storage vessel is held in place by supports connecting the upper and lower ends of the vessel with the walls of a thermally insulated chamber.

Title: Pump for dishwasher - has swivelling inlet pipe to facilitate removal of fine particles of food
Inventor: EIERMANN RUEDIGER
IPC: A47L15/42
Filed: 1976-08-28
Abstract: The machine (10) is provided with an electric motor (15) driving a pump (16) which supplies water to the jet (13) for washing the dishes. When the dishes have been washed a flap (24) in the pump delivery pipe (14) is turned through 90 deg. by an electromagnet (25). The water is then deflected to the outlet pipe (27). At the same time a mechanical linkage with the swivelling inlet pipe (20) rotates it through 180 deg. The inlet is deflected downwards so that fine particles of food which have passed through the strainer (17) are sucked into the pump and discharged through the outlet pipe (27).

Title: Projectile-stopping composite material - contg. steel plates, aramid fibre webs and layers of polyamide 12
Inventor: HAUPT GUENTER ING GRAD
IPC: F41H5/04
Filed: 1976-09-23
Abstract: Composite material projecting human body against projectiles, e.g., a bulletproof vest, consisting of a steel plate(s) and aramid fibre web ('Kevlar'; RTM) is improved in that the steel plate is spatially sepd. from the aramid fibre layer by a layer of polyamid 12 (pref. mainly amorphous; obtd. by polymerisation with use of monomeric lauric lactam). Opt. several layers of aramid fibres (pref. 5-15 webs in each layer) and several polyamide 12 layers can be applied in alternating order. The aramid fibre webs are pref. impregnated and/or densely woven. One or two hard steel plates can be used. Articulate steel plates (e.g., a breast plate and a back plate) are used so that a soft protective construction is produced. The aramid fibres have high resistance against deformation so that they very effectively decelerate the projectile. A similar effect is also exerted by polyamide 12; the latter dams the mechanical vibrations produced by the impact of a projectile. The kinetic energy of the projectile is converted into heat which is absorbed by the polymers when they eventually melt.
