Title: Operation acceleration cct. for electromagnetic relays - reduces relay operation time to 25% nominal
Inventor: NARAYAN VENKAT S DIPL ING
IPC: H01H47/04
Filed: 1973-10-24
Abstract: The basic circuit uses two resistors, one capacitor, two diodes and two contacts. One resistor is connected in series with the relay and they are connected across the D.C. supply through one of the contacts and a forward biased diode. The second diode is used for flywheel discharge of the relay inductance. The second resistor is connected to the capacitor and the second contact. The resistor is thus switched across the supply. The capacitor is connected to the first diode. When the contacts are simultaneously operated the capacitor which was charged to supply potential will be connected to the rail and will back bias the diode and instantaneously place twice the supply potential across the relay and first resistor. This will fall as the capacitor discharges into the relay, and the diode will continue to supply current.

Patent DE-2415704-A1 (DE)
Title: Separator for blood serum - consists of piston in cylinder with filter and valve opened by insertion of rod
Inventor: SARSTEDT WALTER
IPC: B01L3/02
Filed: 1974-04-01
Abstract: Filter for sepg. blood fractions consists of a cylindrical vessel in which runs an airtight piston made from a flexible material, esp. plastic. In this is a filter element which is permeable to serum but impermeable to cake. In series with this is a valve device which seals the outlet neck from the piston. To open the valve a rod is used which has a pair of flights on each side which will rest on the neck of the piston. When depressed, the rod opens the valve and the flights then depress the piston causing serum to flow up through the valve. When the rod is extracted the valve closes automatically. The valve is membrane like deformable disc of a flexible material to which is attached the stopper device for the central outlet on the piston. Alternatively the valve can have a roughened surface in contact with the piston which acts as a filter medium and avoids the need for a separate element. The piston can have a means of attaching a plunger to it in order to use the cylinder as a syringe by attaching a needle to the end.

Title: Switch tube for pneumatic mail capsule conveyor - leaves and approaches connection seat in axial direction
Inventor: KIRK JOHN ROBERT
IPC: B65G53/56
Filed: 1974-09-26
Abstract: A pneumatic conveyor tube (2) for mail capsules is connected to a switch tube (5). The switch tube which can be moved axially can also swivel about a hinge (8) so that a link up with either one of two parallel tubes (3, 4) can be obtained. The switch mechanism consists of a forked lever (27) located on a pivot (26) between the two parallel tubes, and driven by a geared motor (22, 23). When the switch tube is operated, it first moves axially away from its location seat, then it swings through an angle and finally it approaches its new location in an axial direction. This enables the location of an effective seal ring in the link up area.
Patent DE-2448711-A1 (DE)
Title: Shunt connected DC voltage limiting cct. - employs thyristor switch in series with resistor for use with inductively loaded rectifiers
Inventor: SCHULZE MANFRED DR ING
IPC: H02H9/00
Filed: 1974-10-12
Abstract: In rectifiers, or frequency converters with a d.c. intermediate stage, feeding inductive loads transient high voltages may arise. These are sensed by a level detecting element (VD) connected to the common point of a RC element (R1, C2) across the d.c. supply. The level detector output triggers a thyristor (Th) in series with a limiting resistor (Rb), also across the d.c. The thyristor is shunted by an LC element (L, C1). When the voltage level on the first capacitor (C2) rises due to a voltage transient to a predetermined level the detector (VD) responds and excites the thyristor gate, thus applying a controlled short circuit across the d.c. lines. The detector is typically a four layer semiconductor device.

Title: Iron cores choke for radio interference suppression - with a ferrite and iron particle core with particles about ten microns in size
Inventor: KAY ROBERT ANTHONY SMEDLEY
IPC: H01F37/00
Filed: 1974-12-07
Abstract: The use of a core comprising ferrite and iron particles allows the design of a choke sufficiently small to fit into standard domestic installations for example, as part of a light dimmer control for suppressing the radio frequency oscillations set up by the phase controlled operation of the dimmer. The iron particle size should be such that the induced eddy currents do not give rise to any significant heating in the core. In a typical application the core comprises a ferrite rod (12) which fits into a tube (11) made of iron particles bonded together by a sintering process. Over the tube is wound the coil (10) which in turn is covered with a sheath or housing (13).
Patent DE-2504425-A1 (DE)
Title: Reduction of fluid-generated noise in hydraulic systems - pressure oscillation diminished by elastic damping chambers near pumps-etc.
Inventor: MUEHLE CHRISTOPH DR RER NAT
IPC: F16L55/02
Filed: 1975-02-03
Abstract: Sound-damping chambers annexed to hydraulic pipes prevent the onward transmission of sound by reflection rather than suppression, and, indeed, tend to augment the fluid pressure oscillations at the sound source, commonly a pump, motor or valve. In the present alternative the pressure oscillations are diminished by putting the damping chambers close to each source of sound vibration (1), at a distance (a) not exceeding a sixth of the shortest sound wavelength to be dealt with. The chambers (3) contain an elastic medium (4)-gas, or porous, foamed material-retained behind an elastic membrane (5) which itself is protected by a perforated cover (6).

Title: Stabilised anti-skid brake control - with differential pressure valve between two sides of vehicle to prevent slewing
Inventor: GOEBELS HERMANN-J ING GRAD
IPC: B60T8/34
Filed: 1975-02-14
Abstract: The anti-skid brake control divides the braking circuit into two sections, one for each side of the vehicle. To ensure stability for short wheelbase vehicles being braked on uneven road surfaces, a special differential pressure valve is fitted to the T-piece link between the master brake cylinder and the two brake circuits. The valve has two elements, with the elements being subjected to their respective circuit modulated pressure when closed and to the modulated pressure of the other circuit when opened. This provides good lateral stability and safe braking on poor surfaces.
