Title: Storage circuit for electronic emergency-call branch exchange - has clock signal sent via delay line to flip flop
Inventor: SCHMIDT MICHAEL
IPC: H04M11/04
Filed: 1975-03-14
Abstract: The store circuit, for an electronic emergency-call branch exchange, stores the last two keying operations of the attendant operator and also their sequence. A clock signal is sent via a delay line (311) to a flip flop (312) to allow the information about keying to be accepted by a store (32, 33). The clock signal is applied to the set input of the flip flop (312) and is generated by a binary coder (30) that converts the operated key's signals. The output from the flip flop is differentiated by two differentiating units (313, 314), and the differentiated output is used to free a store (32, 33) for accepting the binary signals from the coder (30).

Title: Multiple channel data transmission system - derives channel from coded address using two translations combined with data
Inventor: ZEIDAN DAVID
IPC: H04Q3/545
Filed: 1975-12-11
Abstract: A data transmission system between an exchange and a set of terminal stations uses multiple transmission channels terminated by translations. To transmit data to a data terminal station the exchange derives from the coded address the multiple transmission channel to which the required station is connected. The corresponding translation is marked through an address wire. The marked first translation receives the coded address and the data, and transmits them to a second translation, in which the address is decoded and the terminal station activated. It then receives the data. To transmit data to the exchange the second translation codes the terminal station address and transmits it together with the data to the first translation which transmits a calling signal to the exchange through an address wire. It then transmits the received coded address and the data unchanged to the exchange.

Title: Multiple burglar alarm network - uses glass breakage detection monitor recognises two phase characteristic of breaking glass
Inventor: KARGER WILHELM
IPC: G08B13/04
Filed: 1976-03-19
Abstract: A burglar alarm network uses a number of parallel connected monitors which recognize the characteristic two phase disturbance envelope of breaking glass. The monitors are mounted in a small box (1) on a base plate (2) and are potted in a suitable resin (6). The box is fixed closely to the protected object incorporating typically a glass window. An electromechanical transducer (4) typically a piezo-electric crystal feeds a two transistor amplifier (11, 16) which charges up a capacitance (23) during the first high energy phase of a glass breakage. The longer, low energy signal following this triggers a flip-flop (26, 27) if the capacitance charge (23) is sufficient, and if this happens the central alarm is triggered over the common supply and signal cable (3). Several such transducers can be connected in parallel to this cable, which terminates in a matching resistance (34).

Title: Flow element for liquids and gases - being helical spring coil attached to a mounting with spacers
Inventor: KUNZ GERHARD DIPL ING DR ING
IPC: B01D46/40
Filed: 1976-06-24
Abstract: Flow element for use in liquids or gases has >=1 mounting in the wall or enclosure of the flow space with a passage through it for the medium. This is formed by a compression or a keyed in component. Flow passages are narrow slots when the flow is in one direction but open out when the flow is reversed. This is achieved by the use of an elastic spring as the flow element, the tensile contraction of which is used to ensure the narrow apertures in one flow direction. This spring is a helix and the gaps are the spaces between the windings of the helix. One end is joined to a closure and the other end is fixed to a mounting with a passage through. The element is for use in systems where liquids and gases flow from one space to another esp. where filtration is needed. Permits filtration in one direction but backflushing in the other. The element permits flow through at relatively low pressure drop yet ensuring that blockage does not occur.
