Title: Safety arrangement for doors of transport coaches - has hollow flexible sealing profile with photosensor sensing seal collapse
Inventor: KRAUS VIKTOR DIPL ING
IPC: E05F15/43
Filed: 1977-01-18
Abstract: Closing and sealing arrangement is used for doors or goods or passenger transport coaches. The door has a flexible hollow sealing profile, is reliable in operation and servicing is greatly reduced. One end of the sealing profile cavity (4) has a light radiating device (3) for a light beam (6). The light source can be an electrical incandescent filament lamp or an electroluminescent diode. The other end of the seal cavity (4) has a photosensor such as a photocell, phototransistor or a photoresistor. This arrangement prevents trapping of passengers when the light path is interrupted due to a trapped passenger. It also prevents arbitrary opening of doors by passengers when the door is already shut.

Title: Controlling casting speed of steel ingots - using ladle weigher in electronic circuit actuating bottom pour stopper
Inventor: NASHIWA HAJIME
IPC: G05D9/12
Filed: 1977-02-28
Abstract: Appts. for casting metal ingots uses a ladle with a bottom pour stopper actuated by a servo unit driven by a controller. The controller contains a casting speed programmer feeding the desired speed to both a coupling unit (I) and a comparator fed with the actual speed and the difference is fed to the unit (I) which then actuates the servo. The ladle is weighed and the weighing machine feeds signals to a signal generator which is periodically scanned to obtain signals converted to Sa and fed to the comparator. The generator pref. uses formulae and/or functions derived from the change in ladle wt. w.r.t. time. A second signal generator may be used between the unit (I) and the servo, and additional comparator circuit being connected to this generator.

Title: Tampon for protection against water ingress - with elongated absorbent element mostly covered by elastic sealing coating
Inventor: POPP WOLFGANG DR MED
IPC: A61F13/20
Filed: 1978-10-04
Abstract: A tampon for introduction in the vagina consists of an elongated inner element which consists at least partly of a material with a capacity to absorb water and to swell. Its outside is covered by an elastic coating which is impermeable to liquids except at one narrow end where the water can penetrate. This protects the vagine against the ingress of germs and bacteria from the water in swimming pools. Chlorination is only possible to a certain degree, and water entering the vagina makes the antibody function of the human body inoperative. The new tampon also prevents allergic reactions.

Title: Solar cell with increased efficiency - has buried metal finger electrode system to reduce charge carrier diffusion path length
Inventor: HEZEL RUDOLF DIPL PHYS DR
IPC: H01L31/062
Filed: 1978-10-23
Abstract: Solar cell with increased efficiency consists of a semiconductor conductor device, in which the active regions, in which charge carriers are produced by the incident and penetrating energy, are in at least one electrically insulating layer parallel to the surface. The current produced by the charge carriers is removed by a metal finger system, which is buried in the semiconductor body, instead of applied to its surface. The diffusion path length of the charge carriers to the contacts is shorter than ususal, which increases the efficiency of the cell. The contacts are pref. formed as Schottky contacts or have MIS structure. The insulating layer consists of a double layer of Si oxide and Si3N4 and/or Si oxynitride (produced reaction silane with NH3 and/or O2 in a glow discharge and tempering at 400 degrees C) whilst the semiconductor body consists of mono- or polycrystalline or amorphous Si, Ge or AIIIBV cpds.

Title: Emergency number manual start call transmitter - has tone recognition before number transmission to enable use with common control electronic exchanges
Inventor: SCHROETER JUERGEN
IPC: H04M19/08
Filed: 1979-02-08
Abstract: The emergency number call transmitter for use into electronic common control exhanges. The unit has manual release but the number is not transmitted unitl correct tone is received from the exchanged, i.e. the exchange line scan has cycled until it has scanned this line and recorded an 'off hook' condition and connected it to a register to receive the incoming dialled information, consequently there is no danger of the first digit being lost because the exchange common control was not ready to receive it. The call transmitter has integral batteries charged by the line current available from the exchange. The emergency call transmitter comprises power storage circuit (SV) to supply the exchange tone recognition circuit (ZE), a delay circuit (VZ) and the bistable stores (SP1, 2, 3) coupled to the MF oscillator (MF). When the manual release is operated the bistables are enabled (SP1, SP2) to send the number but are only triggered when the exchange tone is recognised (ZE) and a start pulse sent from an electronic switch (ES) into the delay circuit (VZ) to operate the AND gates and bistables so that the number is transmitted from the multi frequency oscillator (MF).
