Title: Automatic grinding or engraving of glass - according to a pattern, by optical scanning giving electrical control signals for grinder or engraving machine
Inventor: FUELLER HERMANN ING GRAD
IPC: B44B3/00
Filed: 1979-04-25
Abstract: Method of engraving or polishing the surface of a glass body is described in which, by use of various types of engraving or polishing, the bright and dark fields of a picture or grooves corresponding to a pattern, are produced. Specifically the pattern is optically scanned and the bright and dark signals are converted into electrical signals and these are transpose into signals operating an engraving or grinding machine which produces the appropriate hollows and raised areas representing the bright or dark areas. The method overcomes the prior art need for highly skilled operatives using etchants and engraving tools, to obtain the desired patterns, in a costly time consuming way. The method can be used not merely to copy pictures or patterns, but also to produce enlargements or reductions of scale.

Title: Phase difference measurement with optional range expansion - is by successively adding reference increments when threshold difference limits are exceeded
Inventor: MASTNER JIRI DR
IPC: G01R25/00
Filed: 1980-02-23
Abstract: A method and instrument for measurement of phase difference, e.g. in opto-electronic applications, enable optional expansion of the measurement range, e.g. by a multiple of 360 degrees. A phase difference formed from a phase reference signal and a phase measurement signal is converted into analogue form. The analogue signal is monitored for exceeding or falling below an upper and a lower limit respectively. According to the limit check a fixed phase difference value is added to or subtracted from the phase difference. Counter pulses are generated and counted when the phase difference lies outside one or other limit. The difference between the number of times each limit is exceeded is found by subtracting the numbers of each correspondingly generated pulses.

Abstract: The eccentric screw pump is subdivided into several stages by separation planes (18). The stator (1) is formed by distinct stator segments (3) which cooperate with the eccentrics of the rotor formed for example by distinct eccentric discs (22) mounted on a grooved shaft (20). Between the stator and the eccentric of each stage there is inserted an intermediary member comprised of an annular shrouding (240) pivotingly mounted on the eccentric, a piston ring or a wear ring fixed angularly and optionally adjustable longitudinally on the eccentric. The adjacent eccentrics (22) are offset angularly by one angular subdivision of the rotor (tr) about the axis of the shaft (15), the adjacent rings (3) of the stator are offset mutually by an angular shift of the stator (ts) the magnitude of which is twice smaller. The intermediary members (240) are guided by separation planes (18) of the stator. To allow the rotor to freely adapt to an axial thermal expansion different from that of the stator, there are provided free expansion spaces which, in the present case, are formed by annular grooves (67), but which may also be formed by crescent shaped and grooves. The eccentrics of adjacent stages may move in the grooves (67) in case of different thermal expansions.

Patent DE-3118763-A1 (DE)
Title: Electropneumatic door valve
Inventor: SEEGERS GUENTER
IPC: E05F15/50
Filed: 1981-05-12
Abstract: In a door-actuating installation equipped with an electropneumatic door valve, it is necessary for the closing movement of the pneumatically actuated door to be changed over automatically into an opening movement when persons become jammed. Furthermore, it must be possible to deaerate the door drive so that the door can be opened manually. A so-called emergency cock serves for this purpose. When the door drive is aerated again by switching back the emergency cock, the door should not move violently. For this, there is a throttle which may be cancelled only by means of a pulse triggered deliberately. The invention comprises a valve device which embraces the function of the door valve and also the emergency functions described (change-over, emergency cock, throttle).
