Title: Dental X=ray diagnostic unit - has controlled dose rate related to film speed proportional to set signal value
Inventor: GRASSME ULRICH DIPL ING
IPC: H05G1/60
Filed: 1980-11-03
Abstract: The dental x-ray equipment consists of a framework (2), which supports a film holder (3) containing x-ray film (4), a dose detector (5) and an x-ray tube (6). The head of the patient is held in a support (7) ready for taking a series of pictures of tooth or jaw, by rotating the equipment around his or her head. During the filming run, the dose of the x-ray beam is controlled so that after the passing of the pre-set exposure time, an optimum film density ensues. The dose detector (5) is connected to a control unit (8), to whose input (9) a set value signal is applied (10). This set value is influenced by the output signal of a digital- analogue converter (11) which receives its input from a storage unit (12). The store (12) is controlled by a positional transmitter (13) for each position of the exposure unit (1). The set value for the dose output can therefore be related to the x-ray film speed.

Filed: 1980-12-01
Abstract: The top of the chain coupling (3) has a wider slot that does the bottom end, under the middle section of the inserted chain link. A securing bolt (7) passes through the middle of the coupling, between the two parts of the slot, and secures the chain. The wider top prevents the chain from jamming in the slot. The lower slot is wide enough to cater for the maximum tolerance of the chain designed for the coupling. The securing bolt limits the upper end of the narrower section and the wider section also accommodates any central cross link (4) of the chain element, with this link likely to be thicker than the chain.
Patent DE-3105604-A1 (DE)
Title: Mitre-groove cutting apparatus for corrugated cardboard
Inventor: BENKERT STEPHAN ING GRAD
IPC: B26D3/06
Filed: 1981-02-16
Abstract: Mitre-groove cutting apparatus for corrugated cardboard, which can be employed in the corrugated-cardboard box manufacturing and processing industry and also by corrugated-cardboard packaging manufacturers. Thus, for the packaging of large appliances - e.g. dishwashers, etc. - edge guards (corner angles of cardboard), which have to be manufactured in a correspondingly economical manner, are often required for transportation purposes. Hitherto, a bending of the cardboard articles has taken place from case to case up to a certain thickness per flute for this purpose. With thicker cardboard articles, the method has a natural upper limit, so that it will be possible with the above apparatus to produce and manufacture economically also thicker corrugated-cardboard articles as edge guards with a mitre groove, thereby achieving a clean outer edge. A known method merely results in an incision in the corrugated cardboard, so that when edging the material for the protective purpose a relatively sensitive protection results and tears easily. Another method by cutting a V-groove into the corrugated cardboard has the disadvantage that it is not environmentally friendly at the workplace and renders additional chip-exhausting installations necessary. The method described here cuts a mitre groove in the corrugated cardboard by means of two rotating cutters, so that no dust arises and the prism-shaped strip can be easily disposed of as a waste product in an environmentally friendly manner. The apparatus can be built onto existing machines and also employed in special machines. The mitre groove is clean and smooth, resulting in perfect gluing, if desired. The minimum groove spacing is currently 130 mm if a plurality of mitre-groove cutting apparatuses are employed simultaneously.

Title: Equaliser system for equalising transit-time fluctuations and fixed frame displacements
Inventor: SZIGETI TIBOR DIPL ING
IPC: H04J3/06
Filed: 1981-02-28
Abstract: This equalisation of transit-time fluctuations and fixed frame displacements is achieved by the fact that the simultaneous equalisation of the transit-time fluctuations and fixed frame displacements is effected by an information store (SP3) which is used as buffer and which allows a displacement of the loading and reading-out of the information bits within a wide range. The clock phases of the information bits in each case to be loaded and to be read out pass in opposite directions through this information store (SP3). Figure 3 shows the block diagram for the equaliser system (A1...An). The input to the equaliser system (A1...An) is formed by an 8-bit serial/parallel converter (SPW1) into which the input bit streams (I'1...I'n) are loaded and thus divided into packets of 8 bits. <IMAGE>

Title: Circuit arrangement for activating a fluorescent display
Inventor: OLDENDORF CHRISTIAN ING GRAD
IPC: G09G3/12
Filed: 1981-04-18
Abstract: If a fluorescent display and a keyboard are intended to be multiplexed in parallel by a PMOS microprocessor, difficulties arise in the case of relatively large displays since they require considerable current, which leads to a voltage drop at the control output of the microprocessor so that, when a keyboard key is pressed, the signal amplitude at the associated microprocessor input is no longer adequate. The invention therefore proposes to provide a transistor (13 in Figure 1) between the cathode of the fluorescent display and the cathode supply voltage, which transistor disconnects the cathode of the fluorescent display from its supply voltage during a short monitoring period for the keyboard. The display thereby requires no current during this period and the full open-circuit (no-load) output voltage of the control output is available for the keyboard. The application indicates two embodiments for activating the transistor. <IMAGE>

Patent DE-3133436-A1 (DE)
Title: Drawing machine
Inventor: VIGNON LOUIS
IPC: D01H1/22
Filed: 1981-08-24
Abstract: The machine possesses an electric drive motor (M) and a main shaft (H) which is drive-connected to a plurality of rollers (W1-W4, W1'-W4') to be driven, in two drawing heads (11) of the machine. An adjusting belt transmission (V, HO) and a coupling (K) are arranged between the motor (M) and the main shaft (H). The transmission ratio of the adjusting transmission (V, HO) is gradually reduced automatically from a maximum value to the operating value during the starting of the machine, so that the main shaft (H) is accelerated smoothly. Stop devices are provided for automatically stopping the machine when any fault occurs. The stop devices switch off the electric motor (M), release the coupling (K) and actuate a brake (B), acting on the main shaft (H), and an adjusting member of an adjustable pulley (V) of the adjusting belt transmission (V, HO). The brake (B) can be relatively small, since it does not have to brake the uncoupled motor (M). The motor (M) and the adjusting transmission (V, HO) continue to run for a short time as a result of their inertia. During this time, the adjusting transmission (V, HO) is automatically set to its maximum transmission ratio without difficulty, so that it is ready for the next starting of the machine.   <IMAGE>

Title: Brake/clutch combination
Inventor: LINSER JOERG PROF DIPL ING
IPC: B66D1/14
Filed: 1981-09-04
Abstract: This brake/clutch combination with a) the clutch released and the brake in the load-holding position, b) clutch engaged to move the load and the brake released, c) clutch and brake released for free cable (rope) payout, reduces the outlay on construction and space as compared with the hitherto customary embodiments by limiting the number of parts to the minimum. Thus only a single friction disc is used for both the braking and coupling operation. The series arrangements of the clutch and brake makes possible an enforced overlap of the braking and clutch torque, as required for reasons of safety. By displacement of the clutch disc (7) to the left, a clutch torque is built up via the friction disc (11) while, at the same time, the braking torque between the pressure plate (12), the friction disc (11) and the braking surface (8) is reduced. The input shaft (1) thus takes along the output shaft (15) without an interruption to the cable force. By displacement of the sleeve (13) to the left, the transmission of force from the spring element (14) to the braking surface is interrupted and the brake is released to allow free cable payout. The series connection of the brake and clutch permits coupling and brake release with just a single expenditure of force. <IMAGE>
