Title: Drop bolt emergency lock opened from outside - has link bolt tongue extending through bolt head
Inventor: GROTHE UDO
IPC: E05C7/04
Filed: 1979-04-10
Abstract: The drop-bolt-type emergency lock is opened from outside, having external and internal handles, and is for doors of transformer sub-stations etc. so that maybe inadvertently trapped inside can get out, but only authorised personnel with keys can get in. The bolt head is guided in the lock plate opening, and a link-bolt slides parallel to it, being brought into three different positions by a key which can turn through two revolutions, and moved back by an emergency lever actuated by the internal handle. A coupling member between the handles is engaged and disengaged by the link-bolt. On the link-bolt (32) is a tongue (32") extending through the lock-bolt head (20') and beyond it in the initially-locked position. This is thrust back by a locking lever (44) on a window-fastener-type lock (4) for emergency use, on the opposite door leaf.

Title: High-quality lead crystal glassware mfr. - by melting glass pellets in continuous first stage to make glass balls, and melting balls in discontinuous second stage that supplies moulds
Inventor: SIMMINGSKOELD BO KURT WILHELM
IPC: C03B7/00
Filed: 1979-04-23
Abstract: Production method for high quality decorative household articles made from lead crystal glass where, in the initial process step, glass beads are made in a continuous, 24 hr. per day operation. Subsequently the beads are remelted in small batches and fed to moulds for continuous production of the articles. The method of continuous production of the glass beads in the first step makes full use of the high investment value of the equipment required, is conservative in the use of energy and gives good working conditions with a minimum of atmospheric pollution, whilst at the same time avoids the problems of maintaining high quality under continuous shift working and also enables the type of glass to be changed quickly and inexpensively in the second batchwise process step. A closed furnace can be used in the second step.
Patent DE-2917655-A1 (DE)
Title: Thermal stratification prevention system - transports air at ceiling of closed room to bottom of room or vice=versa
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: F24F7/007
Filed: 1979-05-02
Abstract: The system avoids the usual thermal stratification in an enclosed space. The hotter air near the ceiling of the room is transported downwards to where the air is colder. Conversely the colder air at the bottom of the room may be extracted and transported upwards. It is then re-introduced at the top of the room just under the ceiling. This produces a mean temp. between the max. and min. Heat losses to the outside are reduced, as the system essentially only mixes the air in the room.

Title: Double-sided integrated circuit mfg. process - permitting matching and adjustment of component values before final connection
Inventor: PRISILLE KLAUS ING GRAD
IPC: H05K1/09
Filed: 1979-06-01
Abstract: The circuit components (B) with interconnecting conductors (L) are applied to both surfaces of a substrate, for example by screen printing processes. Conductors (L) are brought from each component (B) to one edge of the substrate where they end in terminals (1-11;1'-11') for the upper (Fo) and lower (Fu) substrate surface. Where necessary, open link points (B1, B2, B3) may be included in the conductors. In this state the values of individual components, for example resistors and capacitors, can be measured and adjusted. After setting the correct component values the necessary links can be fitted (B1-B3) and the required interconnectors between upper and lower sides made by connecting terminals together (for example 4-4';8-8'). The circuit is now ready for final surface treatment and encapsulation. The proposed mfg. process makes improved use of the available substrate area, and can also assist in reducing mfrg. time.

Title: Contact thermometer with mercury temp. sensor - has several chambers surmounted by capillaries into which circuit contacts project
Inventor: LAPPE ULRICH
IPC: G01K1/18
Filed: 1979-06-20
Abstract: A contact thermometer uses a relatively large amount of mercury in its temp. sensor yet maintains a low time constant. The sensor is immersible in the medium whose temp. is to be measured. Thermometer capillaries are mounted above the sensor to receive the mercury upon heat expansion. Two contacts of an electrical circuit delivering a control signal project into the inner space of the capillaries. These contacts are closed by the mercury rising against the force of gravity. The temp. sensor consists of several chambers around which the medium can circulate. They are spatially connected to receive the mercury and form a space with large inner wall surfaces w.r.t. the vol. of the spaces. Their walls are of a material that is chemically inert w.r.t. mercury and whose heat conductivity is equal to, or greater than, that of mercury.

Title: Trolley-bus with energy feedback via hydrostatic system - supplies braking pressure energy to hydraulic store with converter and pump with motor
Inventor: SAHM KARL
IPC: B60K6/12
Filed: 1979-09-22
Abstract: The trolley-bus incorporates a system for hydrostatic recovery of braking energy. It is able to travel a long distance without drawing power from the overhead lines. The braking energy is in the form of pressure energy which is transmitted to the hydraulic store supplied by a hydrostatic converter. The energy can be transmitted to the driving axle, or drive wheel, or the vehicle. The drive axle or drive wheel is only driven by the hydrostatic converter. The hydraulic store is charged by the hydraulic pump. This is achieved either via the gears or used to supply an electric motor.

Title: Moisture proof power cable - with elastomer stuffed conductor core enclosed in sectional wire layer
Inventor: RICHTER SIEGFRIED
IPC: H01B7/285
Filed: 1980-03-06
Abstract: An electric power cable for medium and high voltage, with a plastic insulation has a stranded conductor which is protected against moisture by stuffing an elastomer material, such as silicone rubber, petrojelly or a thermoplastic elastomer, in the cavities between the stranded wires.
