Patent DE-2964948-D1 (DE)
Title: Device for supplying the cross warp threads in a weaving machine
Inventor: KOCH BERNHARD ROBERT
IPC: D03D47/44
Filed: 1979-06-11
Granted: 1983-04-07
Abstract: The crossing thread supply system for the weaving machine employs a rotatable bobbin carrier and a thread tensioning means for controlling a thread pay-out from a bobbin on the carrier as a function of thread tension. The tensioning means employs a control lever which is pivotable under the influence of the paid-out thread and a pivoting lever which engages via a pawl with a ratchet wheel connected to the bobbin carrier. The control lever serves to pivot the pivoting lever when moved to an innermost position. This disengages the pawl from the ratchet wheel to permit indexing of the ratchet wheel and bobbin carrier.

Title: Adapter for gas discharge tubes fed from ac mains
Inventor: WALZ ALFRED PROF DR ING
IPC: H05B41/04
Filed: 1980-03-21
Granted: 1982-05-19
Abstract: A starting circuit for gas discharge lamps, such as fluorescent lamps, includes a relay coil controllable switch. A rectifier-multiplier has its input connectable to the alternating-current mains via the controllable switch. A polarity-reversing switch is coupled to an output from the rectifier-multiplier for supplying direct-current to electrodes of at least one gas discharge lamp. Devices responsive to energization of the mains effect reversal of the polarity-reversing switch upon each energization of the mains. A time-delay relay responsive to each energization of the mains effects the closing of the relay coil controllable switch subsequent to each polarity-reversing action of the polarity-reversing switch.

Abstract: An endoscope ocular device (1) comprises a hollow cylindrical housing (2) and a return ring (28) which is ro- atably mounted on the housing (2), and rotated with a photographic camera (106) fixed in place, whereby adjust- ng an ocular (12) to a prescribed dioptric position, no natter how the ocular (12) was previously disposed. A contact chamber (60) is provided between the return ring (28) and housing (2). Provided in the return ring (28) is a first contact (43), one end (44) of which is exposed to ihe outer periphery (45) of the return ring (28), and the other end (46) of which projects into the contact chamber (60). Provided in the contact chamber (60) is a second contact (47) which is removed from the first contact (43) when the photographic camera (106) is taken off, and connected to the first contact (43) when the photographic camera (106) is fixed in place, and is also connected to an electric power source (113). That end (44) of the first contact (43) which is exposed to the outer periphery (45) of the return ring (28) is accessible and can be cleaned with water quickly and reliably. Where the photographic camera (106) is taken off the ocular device (1), the first contact (43) is disengaged from the second contact (47). Therefore, the operator who happens to touch the exposed end (44) of the first contact (43) is not subject to an electric shock.
Patent DE-3068391-D1 (DE)
Title: Mechanical snubber
Inventor: SULZER HARRY EDWARD
IPC: F16L3/20
Filed: 1980-01-09
Granted: 1984-08-09
Abstract: A mechanical, seismic-shock-absorbing snubber adapted to accept extremely high impact loads that may be imposed upon it by reason of its interposition between heavy, relatively moveable structures. While permitting essentially unrestricted, slow, relative motion between the structures, such as may be caused by thermal effects (e.g., the expansion or contraction of a high pressure steam pipe yieldably attached by way of hangers or supports to a building structure as in a nuclear power plant), the snubber limits both the velocity and acceleration of relative motion between the structures such as might result from violent seismic shock or vibration. The snubber employs, as its damping mechanism, an escapement wheel, which rotates in response to relative movement of the structures between which the snubber is interposed and employs a cooperating, pivoted, pallet member of predetermined effective mass driven by the escapement wheel into oscillation. It is the oscillation of the pallet member, the rate of which is limited by the pallet member's mass and natural period of oscillation, that resricts or damps the velocity and acceleration of relative motion between the structures with which the snubber is associated. Alternatively, instead of employing an escapement wheel, a rack may be employed, with the teeth of the rack engaging hooks or pallets on the pallet member to drive the latter into oscillation as the rack is moved relative to the pallet member.

Granted: 1989-03-09
Abstract: An audio signal transmission system having a noise reduction circuit (6), which includes a transmission medium (101) such as a magnetic tape to be used to transmit a digital signal converted from an input audio signal and thereafter to output the audio signal reproduced from the digital signal, a digital signal transmitter having a pulse-code modulator and demodulator (MODEM) (9). The noise reduction circuit (6) includes a compressor (20) for compressing the dynamic range of the input audio signal according to the detection level obtained by detecting at least the high-frequency components thereof in order to supply the output from the compression to the digital signal transmitter and an expan- ,der (21) for expanding the dynamic range of the demod-I ulated signal from the transmitter according to the detection level of at least the high-frequency components thereof. The transmission system has a low-pass filter which limits the frequency band of the input signal to be supplied to the dynamic-range compressor (20) to at most half the sampling frequency of the MODEM (9) and thus permits the noise reduction circuit (6) to compress and expand signals supplied thereto in the same frequency band without causing any erroneous operation.
