Patent DE-3034998-A1 (DE)
Inventor: HANSEL NORBERT
IPC: E05B35/08
Filed: 1980-09-17
Abstract: The authorisation lock (31) for a plurality of locking positions possesses, for the key (33), an extension (34) which projects beyond the lock cylinder (12; 32) and which can be connected to a contact element (36) assigned to the lock. Affixed to the extension is a coding (35') which cooperates each time with one of a plurality of stops (42, 46, 49) arranged at different angles of rotation. The outside diameter of the lock is thus not increased in spite of blocking members, so that it can also be inserted into contact elements and versatility of use is therefore provided. A key introduced into the lock can consequently thus be rotated only as far as the authorised position, since rotation is limited by the stops and by the coding of the key. <IMAGE>

Patent DE-3045435-A1 (DE)
Title: Knots in sawn timber are secured - by polyurethane dowel cast into blind hole drilled through knot
Inventor: BOXLER JOHANN
IPC: B27G1/00
Filed: 1980-12-02
Abstract: The quality of sawn timber, esp. wide, flat timber such as planks, boards etc., containing black knots is improved by drilling a narrow blind hole (30) into the plank and extending at least as far as the boundary of the knot, pref. some distance into the knot, and then injecting into the blind hole under high pressure a metered quantity of polyurethane casting material. The blind hole may be drilled first through the knot (12) and then continue into the parent timber (10). Process is used in particular for planks, boards etc. where the appearance of a "black knot" detracts from the quality. A "black knot" is defined as a knot where the dead wood has shrunk away from the parent timber but still remains in place. The polyurethane material possesses good flow properties, makes a firm and permanent connection and resists impact.

Title: Circuit arrangement for establishing phase synchronism between clock pulses and sync bits of data envelopes
Inventor: KLOPPE KARL DIPL PHYS
IPC: H04L7/04
Filed: 1981-02-03
Abstract: Circuit arrangement for establishing phase synchronism between clock pulses (T10) and sync bits (S) of data envelopes (EV1, EV2) which in each case contain n bits and are transmitted within the framework of a data signal (D10). The data signal (D10) is delayed by a number of cells of a shift register (SR) and forwarded via a switch (SW) to a comparator which compares bits which are n bits apart from one another with one another and transmits comparison signals (V1) or (V2) which signal defective or, where appropriate, identified synchronisation. A first counter (Z1) counts the comparison signals (V1) relating to the defective synchronisation and, once a predefined counter reading is reached, transmits an error signal (F) to a second counter, which controls the switch (SW) according to its counter readings. <IMAGE>
Patent DE-3104513-A1 (DE)
Inventor: ZEITRAEG ROLF DIPL PHYS
IPC: H04B14/04
Filed: 1981-02-09
Abstract: 1. Method of converting linear-coded PCM-words into non-linear-coded PCM-words (companding) and vice versa for converting non-linear-coded PCM-words (linearisation), in accordance with a 13-segment curve which obeys the A-law, using a shift register into which, in the case of companding, a linear-coded PCM-word is input and is shifted until a significant bit appears at the shift register series output, whereupon, for the formation of the non-linear-coded PCM-word, the complement of the bit combination which characterises the number of shift clock pulses required for this purpose is used as higher-value word component, and a number of bits which follow the afore mentioned significant bit and which are contained in the shift register are used as lower value word component, and in the case of linearisation, the lower-value word component of a non-linear-coded PCM-word, which word component corresponds to the grading within the segments of the aforementioned curve, is input and shifted by a number of digits which is related to the relevant segment number of the curve, designated by that part of the non-linear-coded PCM-word which has not been taken into account, whereupon it is used, with the value which has been hereby changed, in order to form the higher-value part of the linear-coded PCM-word, characterised in that in the case of companding, the advance of the linear-coded PCM-word (L) which has been input into the shift register (SCH) and which is to be converted is prevented also when the aforementioned significant bit does not appear at the shift register series output but information shifts have taken place in a number which is 1 smaller than the highest segment number (7), and a counter (Z) which serves to count the shift clock pulses (t) and which is normally brought to a halt when the significant bit appears and whose count then indicates the complement of the number of the segment at which the converted PCM-word is located, is stepped on to its end count, and that in the case of linearisation, the lower-value portion (d, c, b, a) of a non-linear-coded PCM-word (K) which portion corresponds to the grading within a segment, prior to input into the shift register (SCH), is added to a specific bit combination if the PCM-word is assigned to the lowest-value segment (0) of the curve, and is added to another specific bit combination if it is assigned to a higher-value bit combination.

Title: Pulse-Doppler radar receiver
Inventor: KLEMM RICHARD DR ING
IPC: G01S13/44
Filed: 1981-03-06
Abstract: A coherent integration of phase monopulse signals by means of discrete Fourier transformation is carried out in both the summation channel and the differential channels, separately for the distance elements, and the detection threshold is then determined through averaging via the output voltage of all Doppler channels of the discrete Fourier transform. The quantities are then formed from the complex output signals of the individual Doppler channels, the maximum of these values being compared with the determined detection threshold. If the threshold is exceeded, the radar target data are forwarded for target tracking evaluation. The Pulse-Doppler radar receiver according to the invention is suitable for use within a computer-controlled multifunction radar, in particular with an electronically phase-controlled antenna array. <IMAGE>

Patent DE-3115114-A1 (DE)
Title: Slide valve
Inventor: RICHTER RUDOLF
IPC: F15B13/04
Filed: 1981-04-14
Abstract: Slide valve for connecting a pump to a preferably reversible consumer, with an annular groove on the slide, which, in its neutral position, connects the pump to a drain line, the pump being connected to a feed line to the consumer in a set position of the slide and at the same time a return line of the consumer being connected to a drain line. In this arrangement, the slide has an axial bore in which a brake piston serving to choke the flow from the consumer to the discharge can be displaced against the force of a spring. The brake piston in turn has an annular groove which, in one position of the brake piston, connects transverse bores in the slide to one another, one of the transverse bores being connected to the return line, and the other to a drain line. To permit steady braking of the consumer and to prevent the consumer from moving quicker in the braked state than corresponds to the flow supplied, a choke point is arranged in the feed bore in the slide and a choke point is arranged in the brake piston, the space which acts upon the brake piston being in the pressure-medium flow between the two choke points.

Title: Device for holding solid objects, especially telephones, and the articles required for using the telephone
Inventor: LAPP OSKAR
IPC: H04M1/15
Filed: 1981-04-30
Abstract: The invention relates to a device for holding telephones and the associated automatic telephone cable reeler which is mounted for non-stationary use or is firmly integrated in the device, and the articles frequently required for using the telephone, such as telephone directory and writing utensils. According to the prior art, telephone holders are available in many designs. These have the disadvantage that they serve only for mounting and do not offer the possibility of automatic cable reeling. Additionally, it is not possible according to the prior art to use the stored telephone directory without removing it from the storage place. The object of the invention is to eliminate the disadvantages and, at the same time, to achieve a wide field of use and thus a practically suitable and economic solution. In addition to the preferred use as a telephone workplace, the device can also be used as a desk or lectern. The object of the invention is thus achieved, in that an automatic cable reeler with a suitable holder is accommodated on the flat upper side of the device. The underside of the device forms a sliding shelf, preferably for using an open telephone directory which does not have to be removed or changed in its position for this purpose.

Title: Method of determining the ignition processes for internal combustion engines with unsymmetrical ignition sequence
Inventor: SCHLEUPEN RICHARD DIPL ING
IPC: F02P3/045
Filed: 1981-05-20
Abstract: A method for determining the ignition processes for internal combustion engines with unsymmetrical ignition sequence is proposed, counting pulses for determining engine speed-dependent count values being counted during angular intervals of a rotating which consist of two signal generator signals generator arrangement (10 to 17), which signals detect unequal angles, in an alternating sequence. The intermediate count value reached in each case after the first signal generator signal is tested for a specific ratio in relation to the engine speed-dependent count value reached and, as a function thereof, a trigger count value which is assigned to the shorter or longer angle is counted out. As a result, the counter for determining engine speed-dependent count values is simultaneously used to take a decision as to whether a short or long angular segment is present in the following, that is to say which associated trigger count value is to be counted out. <IMAGE>

Title: Self-cocking block breech for hunting and target rifles
Inventor: PONTA ENGELBERT EDMUND
IPC: F41A19/49
Filed: 1981-05-26
Abstract: The invention relates to a self-cocking block-breech rifle which affords excellent preconditions for accurate firing with the shotgun trigger for shooting at fleeing game and with the adjustable German hair-trigger. The impact transmission to the ignition pin by the striking roller takes place with minimum friction. The construction of the striking angle with the rollers is extremely space-saving. Absolute opening reliability is achieved by the immediate cocking of the striker during the opening of the breech by the cocking roller. The striking pin is relieved immediately. The extractor is suitable for rimmed and rimless cartridges because of the shape of the extractor angle and is variable by varying the breast of the extractor lever in the extractor path. The connection of the opening lever with a trigger group (12-21) to the block affords the best possible assembly and dismantling preconditions. The construction is characterised by an easily understandable arrangement of all the parts, with very good production possibilities.
