Title: Telephone exchange out going junction selector - stores two incoming pulse trains then searches and marks junction over signalling wire
Inventor: KROP GUENTER
IPC: H04Q3/00
Filed: 1980-06-26
Abstract: The selector has an extended bank capacitor to enable it to accommodate up to 12 trunks on each level. The selector has two pulse storing circuits for two incoming pulse trains which control the marking trunk search relay circuitry. Earth pulses incoming on the speech wires operate two relays plus a third having a delayed release circuit. Pulses are then stored in contact banks. Further relay operate sequences enable a further pulse train to be stored. Finally, one control relay drops out and the search and mark procedure over the c wire is initiated.

Apertures along the groove are closed by lock segments shaped to match the blade foot. The aperture and lock segments facing this are angled to the blade-axis plane (A-A), the segment being locked in by a spacer (4) fitting tightly between the two surfaces. The spacer may be parallel-sided, but pref, the spacer angle (alpha 1) is slightly greater than that of the lock segment (alpha 2). A wedge (5) forced into a radial slot in the spacer during insertion pushes its sides to fill the gap.

Title: Active carbon fabric - is of fibres which can be converted to active carbon
Inventor: BREMUS HERMANN-JOSEF
IPC: B01J20/28
Filed: 1980-10-04
Abstract: The fabric is constructed of a fibre material which, when treated, becomes an active carbon prod. The fibre for conversion to active carbon, is of natural fibres, artificial fibres of a vegetable or synthetic base, or a mixt. The raw material is in the form of a slubbing, a single or multiple yarn, braiding, woven fabric, felting or matting. High tensile fibres with a high heat resistance are included to increase the strength of the end prod. using glass, aramide, metal, graphite, or boron fibres or mixts. The added fibres can be introduced as a mixed yarn, additional yarns, or an additional woven layer to give an added mixt. of 1-10 wt.% or 11-20 wt.% or over 20 wt.%. The air permeability of the activated fabric is 0-100 (or more) 1/dm2/min at 20 mm water column. The activated fabric is clad on one or both sides with an air permeable material. The process simplifies the mfr. of an active carbon material, for gas masks or other similar applicns., which can be developed in a number of grades according to use.
Patent DE-3041557-A1 (DE)
Inventor: HEINZLE AUGUST
IPC: D05C9/16
Filed: 1980-11-04
Abstract: In conventional embroidering machines, there are provided at the longitudinal ends side cheeks which carry the embroidering tools and which have guide parts for displacing the creel. The vibrations of the embroidering tools are transmitted to the entire embroidering machine and therefore also to the embroidering creel. According to the present invention, the guides for the embroidering creel (4) are to be separated from the side cheeks, carrying the embroidering tools, and intermediate struts. For this purpose, two stationary, horizontally extending guide rails (8, 9) are provided as a supporting part (3) for the embroidering creel (4), and two travelling rails (10, 11) extending at right angles to these are movable in the horizontal direction in the guide rails (8, 9). The embroidering creel (4) is then mounted on the travelling rails (10, 11) so as to be vertically displaceable. The drive for the horizontal movement of the travelling rails (10, 11) and for the vertical movement of the embroidering creel (4) takes place from an embroidering machine, and for example this drive can take place via cable pulls (15, 16, 17, 18) which start from the output shafts (14, 35) of the embroidering machine. <IMAGE>

Patent DE-3104078-A1 (DE)
Inventor: RUHENSTROTH-BAUER GERHARD PROF
IPC: G01N33/84
Filed: 1981-02-06
Abstract: A process for determining the pH value in the interior of a cell is described. This is accomplished by measurement of the emission of a fluorescent substance which is absorbed by the cell through incubation in a solution. The solution contains a compound of the said fluorescent substance; the fluorescent substance is separated from this compound in the cell by an enzyme present in the cell. The fluorescent substance selected is one such that the frequency of the emission maximum is dependent on the pH value. The compound of this fluorescent substance which is selected is one which is membrane penetrating. Measurement of the fluorescence is based on the principle of measurement of the frequency at which the emission maximum occurs. A fluorescent substance suitable for this purpose is 2,3-dicyano-1,4-hydroquinone. A suitable membrane penetrating compound is 1,4-diacetoxy-2,3-dicyanobenzene or 1,4-dibutyryloxy-2,3-dicyanobenzene or 1,4-di(-tert-butyloxycarbonyl-1-alanyloxy)-2,3-dicyanobenzene.

Title: Circuit arrangement for a stored-program controller
Inventor: BADER VOLKER DIPL ING
IPC: G05B19/045
Filed: 1981-02-21
Abstract: This controller is used for controlling machining and processing machines. The aim of the invention is to minimise the circuit complexity in input arrangements, particularly the use of selection circuits for variables. The object of the invention consists in restricting the number of required multiplexer inputs to the simple number of input variables. This object is achieved by the multiplexer output being associated with a controllable negator so that the multiplexer output signal can be forwarded in true or negated form in dependence on the stored program. The invention can be applied in the entire field of digital data processing for selecting variables in time-division multiplex. <IMAGE>

Title: Annular-gap magnet system for dynamic loudspeakers
Inventor: STEINGROEVER ERICH DR ING
IPC: H04R9/02
Filed: 1981-03-07
Abstract: The invention relates to an annular-gap magnet system for dynamic loudspeakers, the air gap of which is formed by a top plate with a pole opening and a pole core of iron, arranged therein, and through which a magnetic flux generated by an annular permanent magnet passes. The zones of the top plate (4) and of the pole core (2) adjacent to the air gap (3) consist of pressed parts (7, 8) which can be annular or plate-shaped and are manufactured of iron powder with a plastic binder. Due to the pressed parts, the eddy currents impairing the frequency response of the loudspeaker and generated by the voice coil currents in the iron poles close to the air gap are reduced in a simple and inexpensive manner. <IMAGE>

Title: Air-conditioning floor
Inventor: HAUGENEDER HANS ING
IPC: F24D5/02
Filed: 1981-04-28
Abstract: The invention relates to an air-conditioning floor which consists of distance elements mounted on a subfloor and a cover layer supported by the distance elements. In the interspace defined by the distance elements between cover layer and subfloor, the heating pipes are laid, preferably in a meandering shape. Through the interspace and past the pipes, an air flow is generated, which after heating by flowing around the pipes is conducted into a room. According to a preferred embodiment, the air-conditioning floor can be combined with a floor heat exchanger so that, in the summer, incoming air cooled by the floor heat exchanger can be guided into the room interior and, in the winter, air preheated by the floor heat exchanger can be introduced into the interspace. The incoming air guided into the interspace can, in summer, be further cooled by the pipes if the pipes are charged with cold water or another cold-transmitting medium whereas, in winter, the incoming air supplied from the floor heat exchanger is heated by the pipes, the pipes being charged with a heat-transmitting medium.

Title: Arrangement for a double-sided cooling of disc-type semiconductors
Inventor: RENESSE EKKEHART VON DR ING DR
IPC: H01L23/467
Filed: 1981-07-31
Abstract: This arrangement uses the shaft type of construction for forced cooling over heat sinks, the coolant remaining separate from the voltage-conducting parts of the semiconductors. To combine the cooling advantages of the double-sided cooling with the space advantages in the case of unilateral cooling and taking into consideration ease of maintenance of the devices and low smoothed constructional height, it is proposed that the heat sinks of both sides of the disc-type semiconductor (1) are arranged in a common cooling duct (9), one side of the disc-type semiconductor (1) being directly connected to the associated heat sink (2) and the other side of the disc-type semiconductor (1) being raised indirectly via a U-shaped cooling rail (3), which can be adapted to the spatial conditions and on the side legs (4) of which other heat sinks (5, 6) can be mounted, to the cooling duct level. <IMAGE>
