Title: Control circuit arrangement for an electrically operable clutch of a motor vehicle
Inventor: LUTZ DR DIETER
IPC: F16H63/46
Filed: 1982-12-22
Abstract: The control circuit arrangement for an electrically actuatable clutch (7) of a motor vehicle, the gear (5) of which is to be shifted by means of a gear shift lever (3), comprises a switch (9) responding to the shift movement of the gear shift lever (3) and initiating the clutch release operation. With a setting member (11, 17), for example the accelerator pedal or its actuating linkage, which determines the engine output of the motor vehicle, there is coupled a positional device (21) which renders the switch (9) inoperative when the setting member (11, 17) is in positions in which the engine rotation rate, in operation of the engine under no load, exceeds a predetermined limit rotation rate. In this way the disengagement of the clutch during driving by unintentional contacting of the gear shift lever (3) is prevented. A further switch (19) may be closed when the accelerator pedal is in the idling position. The clutch may be controlled by a logic network with the switches (9, 21) in series or parallel or incorporated in voltage divider networks. The positional device may be in the form of a potentiometer. A constructional form for switches 19 and 21 is also disclosed. <IMAGE>

Title: 'Peel apart' coloured photosensitive materials
Inventor: GASSON JOHN PHILIP
IPC: G03F7/34
Filed: 1983-11-07
Abstract: Photosensitive materials comprising two carrier sheets having therebetween a photo-polymerisable layer which contains a light- attenuating, non-photosensitive dye or pigment and material which changes colour under the influence of actinic radiation. When the photosensitive material is imagewise exposed to actinic radiation the photo- polymerisable material is polymerised and the colour changeable material changes colour in the exposed areas. Thus there is obtained an image which is immediately visible after the imagewise exposure step and accordingly can be used to check that exposure has correctly taken place and which is developable by peeling apart of the two carrier sheets whereby the material therebetween shears imagewise along the edges of the image areas. The photosensitive material according to this invention is particularly useful in the production of sign making materials and in the production of dry transfer materials.

Patent GB-2141108-A (GB)
Title: Continuous feeding tape
Inventor: YAMASHITA KYOUICHI
IPC: B65H35/00
Filed: 1984-05-14
Abstract: A first tape (T1) is fed to a cutting station (5, 6) in a bookbinding or other machine by a drive arrangement comprising a capstan (3) and a pressure roller (4). At the cutting station, sections of the tape of predetermined lengths are cut off for feeding to a next workstation of the machine. When exhaustion of the first tape (T1) is detected, a standby tape drive (3', 4') is energised, so that the leading end of the standby tape (T2) reaches the cutting station at the same instant as the trailing end of the last section of the first tape (T1). Due to this arrangement, no time is lost through exhaustion of the tape supply. The leading end of the now stationary exhausted tape is retracted back from the cutting station, eg by a deflecting pin or air jet, to prevent interference with the now advancing standby tape. <IMAGE>
