Title: Hydraulic throttle device with permanent flow channel - has channel gap related by mathematical formula to fluid properties and dimensions
Inventor: KATS ARNOLD YAKOVLEVITSCH
IPC: F16K47/04
Filed: 1975-07-11
Abstract: A throttle for the hydraulic circuit of a programmed machine tool or follower mechanism has a circular housing (1) with a groove (5) around part of it, into which fits an insert (6). The latter is of a higher linear coefficient of expansion then the material of the housing. The housing and insert are ring shaped and enclose a rotating cylindrical member (2), leaving a gap (7) between. The width (h) of this gap is given by a formula relating the viscosity of the fluid handled, the length of the gap, the density of the fluid, and the pressure drop inside.

Title: Clock pulse generator with low capacitive load losses - operates by switching reservoir output capacitor to load capacitance
Inventor: BASSE PAUL-WERNER V
IPC: H03K19/096
Filed: 1975-09-08
Abstract: The clock signal generator is designed so that losses due to its having to charge and discharges its load capacitance are reduced. Each output (A) is connected via a MOSFET switch (MS) to an additional capacitor (CZ) connected to earth. The load capacitance (CL) is between earth and the output. When the load capacitance is discharged over the generator by closing the switch a part of this charge flows to the additional capacitor where it is stored. When the load capacitance is charged via the generator the charge is partly obtained from the additional capacitor by closing the switch.

Title: Flexible coupling with flange dogs and cavities - has peripherally grooved resilient pads between coupling faces
Inventor: FAUST WERNER
IPC: F16D3/68
Filed: 1975-09-26
Abstract: The flexible coupling has shaft flange faces which carry alternate dogs (112) and cavities (113). Each dog projects into a cavity on the opposite flange and the dog and cavity flanks are separated by resilient pads (114). The dog, cavity and pad flanks are plane but the inner and outer peripheral surfaces and the radial faces have concave section grooves. In addition ribs ensure that the pads are firmly gripped in the corresponding mounting cavities. This forms a construction of the pads ensures greater flexibility of the coupling together with increased pad life. To aid assembly, the pads may be mounted at equal pitches around a ring. Various basic sectional shapes of pad are possible, such as trapezoidal or square.

Title: Boiler for combustion of solid-or liquid waste material - introduces finely distributed waste and removes combustion residues along vertical walls of furnace
Inventor: THOMAS GUENTER DR
IPC: F23G5/24
Filed: 1975-10-23
Abstract: Boiler handles solid bulk-state waste materials or liquid waste materials, where the unburnt residues tend to bake, sinter, or melt. The material is dosed from hopper (1) by screw conveyor (2) into tube (3) where it receives acceleration by compressed air supplied through tube (4) and is transported to distributing nozzle (5) fitted at the bottom of vertical furnace (6). Fuel, such as natural gas is added via supply line (7) to the nozzle (5) and the mixture is burnt at the bottom of the furnace. The resulting flue gases, together with the unburnt residue travel upwards along the vertical walls of the furnace. The bottom of the furnace is provided with baffle (17) and the resulting gap is connected to cooling air supply (11). Further, at several levels on the vertical walls of the furnace sets of cooling air inlets (12a to 14a) are provided with upwards-directed flow.

Title: Plastics valve spindle with O:ring seal - has integral cover sleeve for protection of O:seal when valve is installed in its working position
Inventor: ANTLINGER HELMUT
IPC: F16J15/32
Filed: 1975-11-25
Abstract: The valve spindle (10) is made from plastic and has an O-ring groove (17) on its cylindrical stem section (13). A knob (14) is provided so that the valve assembly can be placed and removed from its location. An integral sleeve (19) is attached to the leading edge of the O-ring groove. In order to protect the O-ring seal from the aggressive fluids to which the valve is exposed, the thin plastic sleeve (19) slides over the O-ring when the valve is installed in its location. Since the sleeve (19) is only very thin, it does not impair the radial expansion force of the O-ring.

Title: Combustion engine process separates heavy and light gases - ejects medium weight gases and recirculates rest to engine inlet
Inventor: WOODS CLAUDE A
IPC: F02M25/07
Filed: 1976-03-10
Abstract: Combustion engine inlet and exhaust system may further include the elimination of liquids and solids from the separated light and heavy gase, including water, carbon, lead and sulphur, before recirculation. The process may also include maintaining a suitable pressure for the recirculation of the separated gases by a reversal in a section of the flow path in the exhaust system back towards the inlet system before the light and heavy gases are separated. Separation may be effected by separating the upper and lower layers of the exhaust gases flowing through the exhaust system whilst the central core is allowed to pass through.

Title: Miniature laser with lasing crystal - has pumping diode recessed into crystal to move active region away from corner irregularities
Inventor: MAHLEIN HANS DR
IPC: H01S3/0933
Filed: 1976-05-21
Abstract: The miniature laser consists of a lasing crystal (or of a substrate carrying such a crystal and a super-substrate on top of the crystal) and dielectric reflectors covering the ends. An optical diode pump is located on top of the crystal (or the super-substrate). A recess is set into the crystal (or super-substrate) to hold the diode pump arrangement. The recess places the active region (7) of the pumped crystal (1) deeper into the body of the crystal and thereby avoids the drastic reduction in reflector (2, 3) quality caused by the 'humps' (5, 6) at the corners between the surface and ends of the crystal.
