Title: Program controlled machine regulator with card reader - has program store, and microprocessor controlling data reading and machine and has phototransistors in reader
Inventor: BUEHL HERMANN DIPL ING
IPC: G05B19/14
Filed: 1978-07-31
Abstract: The control device is for a numerically controlled machine (6) and has a card reader for cards contg. the machine program which is read in single program steps. The fault rate of the program machine, i.e. the cards, is low. This is achieved without requiring the cards to be re-read in order to regenerate the program.

Title: Active agent storage for inhaler - in felt pads of sector cells in turntable magazine
Inventor: ECK WALTER DIPL PHYS
IPC: A61M15/00
Filed: 1978-08-10
Abstract: The active agent for an inhaling appts. is stored in a magazine consisting of a circular plastic moulding which is subdivided into several sectors. The active agent is contained in the cells in felt pads which have been impregnated with it. On the periphery, the felt pads are accessible through an opening so that end of an ultrasonic atomiser can be urged against them. This is a simple method of ensuring a uniform dosage of the inhaling agent. The magazines are easy to replace.

Inventor: HERMANN MANFRED P DR
IPC: C25C7/02
Filed: 1978-12-13
Abstract: Electrode frame is made by assembling thermoplastic polymer bars for electrolytic winning or refining of metals. The frame is pref. made of polypropylene, and consists of four bars which can be joined together at their corners to make a square or rectangular frame which can be dismantled when required.

Title: Device resembling book for keeping items of jewelry - has flat plates with foam layers having recesses and hooks
Inventor: PANAGIOTOPOULOS GEB KIRNER ING
IPC: B42F5/00
Filed: 1979-01-08
Abstract: Number of flat level plates with rectangular surface, is assembled in binder resembling a book, for keeping of items of ornamental jewellery. On the surface of one plate at least a layer of soft material such as polystyrol foam, may be placed, into which ornaments can be pressed and retained, to be covered by a layer of velvet-like material on an adjacent plate. The layers may also include cushion for pins of brooches, etc. whilst recesses are provided for rings, as well as hooks in appropriate positions such as close to the ears of a photograph. Binder has clamping arrangement for number of plates and is of metal fitted with lock. Conventional jewel boxes have the disadvantage that they are immediately recognisable as such, and that if box is tilted, jewellery is not sufficiently secure to prevent pieces becoming mixed together. Binder overcomes these shortcomings and presents ornaments for selection in a highly aesthetic manner.

Title: Transferring specimens onto thin layer chromatography substrate - after evaporation of solvent vehicle on transfer sheet, giving a conc. spot
Inventor: FENIMORE DAVID CLARKE DR
IPC: G01N30/91
Filed: 1979-05-25
Abstract: A device for applying specimens into a thin layer chromatography substrate consists of a thin support sheet or film with a depression in its upper surface and an appts. for dispacing this depression towards the plane of the upper surface of the sheet, in order to transfer the specimen onto a thin layer chromatography substrate adjacent the upper surface. Pref. a transfer layer or coating is used for preventing direct contact between the specimen together with its solvent vehicle and the upper face of the thin sheet. The initial speciment, together with its solvent vehicle is evaporated onto the transfer to form a small spot of specimen before the transfer operation is carried out. In this way the specimen is more concd. than when it is applied together with solvent onto the substrate, the solvent then being evaporated. The method provides a more concd. spot of specimen.

The outlet of each piston is connected to the conveying side of the compressor via a governor that controls the rate of flow of air and therefore the rate of fall of the pistons. A cam is connected coaxially to the pressure cylinder and controls the duration of the wiper's rise and fall.
Patent DE-2927647-A1 (DE)
Title: Surface measurement using length sensor - speed variation derived from stepping probe and proportional variations in high-pass filter cut-off frequency
Inventor: KREIENSEN KURT
IPC: G01B7/34
Filed: 1979-07-09
Abstract: A surface measurement device has a length measurement sensor moved transverse to the direction of motion of a scanning probe at a speed adjusted in steps. The length measurement sensor produces a surface shape signal which passes through an RC high-pass filter whose boundary frequency is also stepwise adjusted. The danger of filter cut-off frequency adjustment errors is economically reduced or eliminated. The arrangement ensures that the individual step changes in filter cut-off frequency are proportional to the individual step changes in the probe speed. The filter frequency adjustment is achieved using a step switch varying the RC element resistor or capacitor value in factors of two by retaining the connection to tower order stages when stepping up.

Title: Appts. reproducing selected areas of text - uses two filters for determining colour marked zones in two separate scanning operations
Inventor: PFEIFER JOSEF
IPC: H04N1/38
Filed: 1979-07-17
Abstract: Particular areas of text are selected for reproducing by a photocopier. The relevant areas can be marked by black lettering on a white background or a coloured pencil. The marked areas are then scanned. The ordinates for the position of the markings are stored, and the information within the areas are read by the system, during a second scanning operation. The two sets of signals are separated by two filters so that two sets of signals of different frequencies are obtained and converted into control signals for two processing circuits.

Title: Shaping thin-wall honeycomb structure for aerofoil - uses profile milling or abrasive cutter working at specified high cutting speed
Inventor: PREIS HANS
IPC: B24B1/00
Filed: 1980-01-24
Abstract: The arrangement is intended for machining thin-walled honeycomb structures, such as may be used for reinforcing aerofoil sections. The operation is carried out by a milling or abrasive cutting tool using a cutting speed between 30 and 100 m/s, preferably between 40 and 80 m/s, or 50 to 60 m/s. The use of these speeds eliminates deformation of the thin honeycomb walls and burred cuts. Air pressure may be introduced (via 17,14) into the honeycomb cells during the operation. The tool used may consist of a number of milling discs (5) of different diameters, with circumferentially offset cutting teeth on a common shaft (6). The envelope curve (7) of the discs forms the desired profile. Similar tools are described for grooving and boring. Cutting teeth may be replaced by abrasive particles.

Inventor: HORSTMANN WINFRIED
IPC: G11B20/18
Filed: 1980-09-08
Abstract: The recording of frequently modulated digital signals is performed to allow accurate time base control of compressed and expanded data.
