Title: Telephone exchange circuit reconnecting calls at subscriber's request - includes metering arrangement for debiting cost of reconnected part of call to subscriber being called
Inventor: FREYMADL GEORG DIPL ING
IPC: H04M15/12
Filed: 1980-07-17
Abstract: The automatic electronic telephone exchange provides facilities for reconnecting incoming calls to a different number at the request of the subscriber being called. Such a request is made by the subscriber and stored in a memory. An incoming call is then automatically reconnected to the given number, and the caller advised of what is taking place. The cost of setting up what is in effect a second call is not however a fair charge on the original caller. The system proposed splits the charges between calling and called subscribers if reconnection takes place. The caller is charged for the call to the number dialled. This charge rate commences as soon as the reconnection process begins. The called subscriber is charged for the call between his own number and the number which he selected for the reconnection. The charging commences when the call is accepted.

Patent DE-3104598-A1 (DE)
Title: Seat belt arrangement
Inventor: ERNST HANS-HELLMUT ING GRAD
IPC: B60R22/24
Filed: 1981-02-10
Abstract: The invention relates to a seat belt arrangement in the region of the deflection fitting which constitutes an important component in the seat belt system. The deflection fitting (1) which is attached to the B pillar (6) of the vehicle transmits the forces in the belt (3) from the occupant to the automatic retractor. In this process, in addition to the main forces in the longitudinal direction, transverse forces also occur on the belt deflection axis (13), which forces result in a disadvantageous slipping of the belt (3). This problem is remedied according to the invention in that the pivot axis (2) of the deflection fitting (1) forms with respect to the direction (4) of travel an angle (5) which is smaller than the customary 90 DEG  and lies preferably between 50 DEG  and 70 DEG . As a result, the deflection fitting (1) is aligned more to the shoulder point of the occupant and the negative transverse forces are produced to a much smaller degree. This special alignment can be achieved by means of a corresponding design in the attachment area of the B pillar (6) or by a corresponding design of the deflection fitting (1) itself. <IMAGE>

Title: Circuit arrangement for generating pulse sequences
Inventor: BEST JOERG
IPC: G06F7/68
Filed: 1981-07-04
Abstract: The invention relates to a circuit for generating an output pulse sequence (AS), the frequency of which is m-times an input pulse sequence (ES). A clock generator (1) supplies clock pulses (T) to a counter (2), the count (ZS) of which is supplied to a digital comparator (3) and to a latching register (10). The latching register (10) receives the input pulse sequence (ES) at its input end and its output end is connected to a digital controller (6) via a memory (8). The digital controller (6) is connected to the digital comparator (3). From the comparator (3), the output pulse sequence (AS) is taken. The phase angle (Tsoll) between output pulse sequence (AS) and input pulse sequence (ES) can be arbitrarily predetermined. The actual value (Tist) of the phase angle is determined and the nominal-value/actual-value difference is corrected with the aid of the controller (6). The invention is suitable as trigger equipment for static converters. <IMAGE>
Patent DE-3127642-A1 (DE)
Title: Heat exchanger
Inventor: STRICKER BERNHARD
IPC: F28F19/00
Filed: 1981-07-13
Abstract: The present invention relates to a heat exchanger for use as cooling assembly of a conventional heat pump circuit for cooling and dehumidifying heavily polluted and dusty air, for example in a cow stable (cowshed) or poultry house (hen house, hennery), having at least one air-conditioning battery which is arranged in a box-shaped flow duct, has expanded coolant of the circuit flowing through it, and is arranged in the flow region of the air and extracts heat from the latter. The special feature of the invention is to be seen in that each air-conditioning battery is arranged spread flat in a flat space which is bounded by extremely smooth plates and surrounded on all sides and which is filled with a medium which is a highly effective thermal conductor, and in that the plates, which are exposed to the flowing air and form the front and rear sides of the space are arranged essentially vertically. As a result of this configuration of the heat exchanger, the dirt settling on the plates can flow off together with the condensed water at the latest when the heat exchanger is de-iced.

Patent DE-3136549-A1 (DE)
Inventor: KRAFT HARALD DIPL ING
IPC: B23B27/16
Filed: 1981-09-15
Abstract: A cutting tool, such as a turning tool, includes a clamping holder with a recess in one of its surfaces, a cutting bit insertable into the recess, and a clamping shoe secured to the clamping holder by a clamping bolt. The clamping shoe has a projecting member engageable within a depression located in the surface of the cutting bit for securing the cutting bit in the recess of the clamping holder. The depression is defined in the surface of the cutting bit by a closed line formed in part by convexly curved first lines and by second lines interconnecting the ends of the first lines. The depression, as viewed in plan, has an oblong or star-shaped configuration. The lines defining such configuration can be convex, concave or rectilinear. The surface of the depression within the closed line is formed by a radius centered at points located outwardly from the surface of the cutting bit containing the depression. Accordingly, the length of the radius is greater than the depth of the depression. The projecting member on the clamping shoe has a half-barrel or half-cylinder shape so that it forms a punctiform contact with the surface in the depression.

Title: Circuit arrangement for telecommunications exchanges, especially telephone exchanges, which are constructed partially using space division matrix technology and partially as time division multiplex coupling arrangements
Inventor: UEBELHACK HEINRICH DIPL ING
IPC: H04Q11/04
Filed: 1981-09-17
Abstract: Expansion units (P, R) for telephone exchanges (L) which are constructed from group and line selectors (I.GW, II.GW. III.GW, IV.GW, LW) using conventional technology are constructed using PCM technology from in each case one line trunk group for digital subscriber points (LTGB1, LTGB2) and one line trunk group for analog subscriber points (LTGA1, LTGA2) and a digital concentrator (C1, C2) which is connected to the line trunk group for digital subscriber points (LTGB1, LTGB2), the two line trunk groups in one expansion unit (P, R) in each case being directly coupled together by means of their connections which are provided for connection to a PCM coupling network. The line trunk group for analog subscriber points (LTGA1, LTGA2) is connected to inputs of II. group selectors (II.GW) by means of its analog outputs (d), and is connected by means of its analog inputs (g) to outputs of group selectors of the same selection stage (II.GW) or a downstream selection stage (IV.GW). A central control mechanism for expansion units is superfluous in the expansion phase. <IMAGE>
Patent DE-3138205-A1 (DE)
Title: Raster and optical limitation pane
Inventor: NAWRATH PETER
IPC: G02B5/00
Filed: 1981-09-25
Abstract: The invention relates to a raster and optical limitation pane made from transparent material, for example acrylic glass, in which vertically extending slots prevent lateral translucency due to the fact that total reflection occurs at the lateral polished surfaces of the slots. The effect is as with a venetian blind, but caused by a different physical mechanism than in a venetian blind. According to the invention, the depth and the mutual spacing of the slots further plays a role with reference to the optical information which is to appear unrecognisably in the case of lateral translucency through the raster and optical limitation pane. <IMAGE>

Title: Sand mixture for producing casting moulds, mould masks and especially cores for metal castings
Inventor: VOHMANN KARL-HEINZ
IPC: B22C1/00
Filed: 1981-11-13
Abstract: A sand mixture for producing casting mouldings, mould masks and core moulds for metal castings consists of quartz sand (2', 2"), iron oxide (1', 1") and synthetic resin binder (3). It should be prepared without special expenditure and be of such a nature that the cracking, based on the so-called cristobalite discontinuity of the quartz sand and causing casting faults, in the casting moulds, mould masks and core moulds is reliably avoided. For this reason, the iron oxide (1', 1") is added in a fine granular form with porous grain structure and in quantities of more than 8 to 40% by weight to the quartz sand (2', 2"), the iron oxide (1', 1") being provided by the hot enveloping method with the synthetic resin binder (3) exclusively on its surface. <IMAGE>

Title: Hydraulic pressure-relief and secondary-suction valve
Inventor: OLBRICH GOTTFRIED
IPC: F15B13/02
Filed: 1981-11-13
Abstract: A hydraulic pressure-relief and secondary-suction valve (14) is proposed, the pressure-relief valve (23) of which works as a dampened, directly controlled differential surface valve. A damping device (38) of the valve body (26) and the guide of the closing member (19), allocated to the secondary-suction function, in a push-in sleeve (15) lie on opposite sides of a plane formed by the two valve seats (17, 27). Despite a simple, inexpensive type of construction and a small overall diameter, a large hydraulic capacity is possible, in which arrangement a hollow-slide type of construction in the pressure-relief valve as well as three components, movable relative to one another, in essentially the same radial plane are avoided. <IMAGE>
