Patent DE-4216289-A1 (DE)
Inventor: KORB KLAUS
IPC: E05C9/02
Filed: 1992-05-16
Abstract: The invention relates to an espagnolette lock actuable by lock cylinder, with a toothed ring which surrounds the locking bit of the lock cylinder and the outer circumference of which meshes with output gearwheels, the rotational movement of which serves, with a reduction gear interposed, for the displacement of the espagnolette; to achieve a simple and functionally advantageous solution, it is proposed that an espagnolette connecting slide (19) consists of two parts (20, 21) which are coupled to one another and of which one is connected to the one espagnolette (4) and the other possesses, for varying the spindle dimension (D), a toothed strip (26) coming into engagement with the output wheel (17) of the gear. <IMAGE>

Filed: 1992-07-01
Abstract: The description relates to a device for cleaning pipes (1), especially beverage pump pipes, with an automatically operating four-way selector valve (3) with a housing (2). The housing (2) has an inlet connection (4) and an outlet connection (5) for a cleaning fluid, two pipe unions (6) and a sleeve (7) to accept a movable piston (8) with two valve apertures (10) in a control surface (9). In the inlet connection (4) there is a valve stub (11) extending as far as the control surface (9). This valve stub (11) has an external catch component (12) and a sealing component (13) movably arranged therein, the frontal surface (14) of which can be pressed against the control surface (9) by a force acting axially which is at least partly generated by the pressure of the cleaning fluid. This design ensures that the sealing component (13) of the valve stub (11) does indeed seal against the control surface (9) of the piston (8) but does not hamper its reciprocating movement.

Title: Lightweight camshaft
Inventor: SPEIL WALTER DIPL ING
IPC: C21D9/30
Filed: 1993-07-23
Abstract: The invention relates to a camshaft formed by a hollow body to give a lightweight camshaft. It is known to slide premanufactured cams onto a hollow shaft and to expand them locally by hydraulic means in order to fix the cams on the hollow shaft in terms of rotation. The disadvantage is that this camshaft construction requires a thick-walled hollow shaft and the advantage in terms of weight is diminished. The object of the invention is to provide a lightweight camshaft which meets the strength requirements and is of simple, economical design. For this purpose, the invention provides a blank (4, 14) which is punched out of the strip of sheet, corresponds to a developed profile of a camshaft (1, 11) and, having been rolled into a cylinder is used to form a one-piece camshaft. As an alternative, a central tube (28) is provided as the main body of the camshaft (21) and the cams (22) are mounted or slid onto it as separate components or fitted directly into the central tube (28) with their points facing radially outwards. <IMAGE>

Title: Device for testing central vision functions
Inventor: BRAEUNING JOHANNES
IPC: A61B3/032
Filed: 1993-08-10
Abstract: Previous examinations of the field of vision required a spatially large system in the form of a perimeter or a (white noise) campimeter with microcomputer, control and video monitor. Examination of the visual acuity and dark adaption required at least one other device. The invention relates to a device and a method for detection of central scotomata or lesions. It is furthermore possible to test the perception on dark adaptation, as well as the visual acuity and the reactivity to optical stimuli. According to the invention, a measurement device is to be created via a display (21), an optical system (27/28/30), a controlable illumination device (23), a computer, a signal emitter and corresponding control cards, the spatial extension of this measurement device resembling that of spectacles. The device can be used to test all important vision functions in the field of vision of 30 to 40 degrees. <IMAGE>

Title: Method for operating a light-barrier device, and apparatus comprising at least one light barrier
Inventor: ENGBERTS UWE
IPC: H05B44/00
Filed: 1993-09-07
Abstract: The invention relates to a method for operating a light-barrier device which comprises at least one optotransmitter and at least one optoreceiver and preferably serves a purpose of recording positions of parts, including (rapidly) moving parts, or of measuring time (time intervals). Furthermore, the invention relates to an apparatus comprising at least one light barrier having an optotransmitter and an optoreceiver. It is the object of the invention to specify a method and an apparatus of the abovementioned generic types in which disturbing influences and other systematic problems are avoided or detected and corrected as automatically as possible. With regard to method, the object is achieved according to the invention by a method which is distinguished in that the light output (brightness) of the optotransmitter is monitored taking account of the output signal of the optoreceiver and is readjusted in the event of an undesired monitoring result.
Patent DE-4333390-A1 (DE)
Title: Method for setting up a connection involving a wireless paging system
Inventor: VANLANDEGHEM MARC
IPC: H04M11/02
Filed: 1993-09-30
Abstract: If the subscriber of a called telephone terminal (KEA) belongs to the subscriber base of a wireless paging system (PSS) connected to the communications system (KS), both the assigned telephone terminal (KEA) and, via the paging system, the corresponding mobile unit (ME) (pocket receiver) are called either automatically or following prior input by the subscriber concerned during an incoming call. If the subscriber answers on any telephone terminal, the pending connection can be set up and switched through to this different telephone terminal due to the fact that this has been initiated by the paging system in the sense of the "Call acceptance" feature. The transmission of the ringing signal to the subscriber's own telephone terminal is simultaneously ended. The program procedures implemented for the "Call acceptance" feature are enabled in that, despite parallel signalling, the normal entries are made in the so-called connection (VS) and queue (WS) memory only for the connection to the subscriber's own telephone terminal. The advantage lies in savings in terms of additional programs and computer capacity. <IMAGE>
