Title: Friction clutch
Inventor: BIRK ALBERT
IPC: F16D13/46
Filed: 1984-03-26
Abstract: A friction clutch for a motor vehicle, has a clutch carrier plate (3) which can be secured to the crankshaft (2) of an engine, an axially movable pressure plate (4), a diaphragm spring (5) disposed between the pressure plate (4) and the clutch carrier plate (3) bearing with radially outward regions against the clutch carrier plate (3) and with radially further inwardly disposed regions against the pressure plate (4). Leaf springs (26) connect the pressure plate (4) and the clutch carrier plate (3). A counterpressure plate (12) is axially and non-rotatably secured to the clutch carrier plate (3) by way of spacer means (13). A clutch plate (10, 11) is disposed between the pressure plate (4) and the counterpressure plate (12).

Title: Conference circuit
Inventor: CROWE DAVID HAROLD
IPC: H04M3/56
Filed: 1984-04-06
Abstract: A simple and economic implementation of a conference facility is provided in a distributed telephone exchange, such as an PABX, solely by equipment at the nodes. It includes samples stores (SS1 ... SSN) connected to the transmission medium (1) so that a number of PCM form samples can be received from the other nodes in the conference. These samples pass via a multiplexer (3) to a digital-to-analogue converter (4) and therefrom via a low-pass filter (5) to the handset. Thus the output to the handset is an analogue signal representing the combined (but not summated) effects of the samples from the other conferees. <IMAGE>

Title: A bearing assembly
Inventor: HOFMANN HEINRICH
IPC: F16C35/067
Filed: 1985-12-18
Abstract: A two-row angular contact ball bearing with two axially spaced inner races arranged in the shaft and outer rings with outer races disposed around the inner races. The outer rings are held apart by a bushing. One end of the bushing rests against one of the outer rings. The other end of the bushing has a radially enlarged end section which extends over the other outer ring and defines a free space between the other outer ring and a shoulder at the beginning of the enlarged section of the bushing. An annular, conical spring is in the free space between the outer ring and the shoulder. A cutout in the bushing enables installation of hardening material in the free space radially outside the annular spring for rigidifying the spacing of the bearings once the shaft carrying the bearings has been installed in a final installation.

Title: Liquid crystal light shutter
Inventor: OTA MORIO
IPC: G02F1/139
Filed: 1986-01-06
Abstract: The liquid crystal 21 of a liquid-crystal light shutter is of the guest-host type and includes a dichroic dye, and serves to pass or absorb the incident light to cause the shutter to be opened or closed. The shutter is provided with polarizing plates 22,23 on either side of the cell 21 with axes 25,29 parallel to each other and to the alignment directions of the cell walls. The polarizers eliminate light leakage when the shutter is closed. The shutter is two-frequency-driven by frequencies (fH and fI) higher and lower than a frequency (fC), which inverts the dielectric anisotropy of the liquid crystal. 
<??>The shutter is used to control writing on to the drum of an electrophotographic copier.

Patent GB-2175672-A (GB)
Title: Thermostatic gas valve
Inventor: ROBERTS PETER DEREK
IPC: F23N5/06
Filed: 1986-03-03
Abstract: A thermostat for a gas valve is calibrated by moving the expansible element 22 in and out of a sleeve 30 32. The sleeve 32 is rotationally free but axially captive in the body of the valve, at least during the calibration step. Hence the element moves 24 axially when the sleeve is rotated. When set to the required position, the element 22 is angularly fixed and this prevents axial movement and prevents the calibrated position being disturbed. The fixing is achieved by making the element angularly fast with the sleeve so that if it turns, both turn together, or by fixing the sleeve 32 against rotation relative to the body relying upon alternative means such as the stiffness of the capilliary tube connected to the expansible element, to prevent angular movement of the element in the fixed sleeve. The sleeve may be crimped to the element 22 to prevent relative movement. Alternatively, fixing may be effected with adhesive or cement. <IMAGE>

Title: Tuning system for a receiver
Inventor: DOMINEY RAYMOND JAMES
IPC: H03J7/02
Filed: 1986-03-21
Abstract: A tuning system arranged to receive an incoming signal, e.g. a signal modulated with teletext data in the case of a television signal, comprises a tuner (10), a decoder (14) and a microprocessor (16). Digital data on the incoming signal is used by the microprocessor to modify the tuner (10). The microprocessor (16) is used in a closed loop system to carry out fine tuning of the receiver and/or selection of a particular transmission. Fine tuning can be accomplished by monitoring errors in the data in the incoming signal. Automatic selection of a particular transmission is achieved by inspecting the data in the incoming signal for a content that is unique to a particular signal source. <IMAGE>
