Patent DE-2339872-A1 (DE)
Title: Pump or rotor gearwheel unit - has pressur medium fed between gearwheel teeth without connection between feed chamber and outflow chamber
Inventor: NONNENMACHER GERHARD DIPL-ING
IPC: F04C2/08
Filed: 1973-08-07
Abstract: Adjustable gear wheel engine e.g. a pump or rotor, with at least two gear wheels in outer engagement with each other, and which are fed with pressure medium into teeth spaces from a feed chamber. This pressure medium is forced out of the teeth gaps into an outflow chamber as the teeth of the gearwheels engage. A controllable channel is provided for the feedback of pressure medium from the outflow chamber to the teeth spaces at the feed side. This channel is so arranged that it discharges into the teeth spaces, and no connection between the feed chamber and the outflow chamber exists. The channel is formed by a recess in the circumference of a non-rotating plate connecting with a rotating gear wheel and an aperture running radially in the gearwheel which corresponds with this recess, ending in the teeth spaces of the gearwheel.

Title: Oblong material feed mechanism - has assembly of rotary tubes indexed into delivery position in turn
Inventor: FORTUNE WILLIAM SAMUEL
IPC: B23B13/02
Filed: 1973-08-17
Abstract: The mechanism is partic. for use with an automatic lathe, and incorporates a rotary assembly comprising tubes, each accommodating a length of material, and parallel to the lathe spindle. The tubes are indexed in turn in line with the latter, whereupon a feed mechanism thrusts the material forward into the machine. The presence or absence of material in a tube is detected, and in the latter case another tube is indexed into position. Compressed air can be used to feed the material forward, supplied from a receiver in a position radially inwards from the tube, and the indexing mechanism can also be compressed air operated.

Title: High pressure flexible hose - produced continuously from a stationary mandrel
Inventor: PAHL KARL-HEINZ DR
IPC: F16L11/12
Filed: 1973-08-01
Abstract: Reinforced rubber hose of bore >=50 mm and length >100 m has uniform cross section lengthwise but pref. has variations in wall thickness and/or reinforcement distribution which induce twist-free flattening of the hose by external pressure. It is produced on a stationary mandrel having >=1 annular array of support surfaces which allow straight (i. e. non-rotating) haul off with negligible friction of continuously laid up pipe. Mandrel supports pref. comprise rollers rotating parallel to the mandrel axis, or fluid pads, or internal conveyors. An external band may oppose torque generated during haul off. Tube walls may incorporate recesses to accept counterweights for under sea use. Wall section or reinforcement pattern may be changed near the ends to accept coupling or fittings. Esp. for mfr. of hydraulically pressurised hose for ocean bottom laying. Lighter and more corrosion resistant than steel pipes, involves few joints because of continuous lay-up and compact, non-twisting coiling characteristics. Undamages if flattened by pressure during laying, can recover shape and sustain an adequate pressure differential between the core pressure and external hydrostatic forces without requiring excessive wall thickness.

Abstract: An optical system is used to provide an image for a character recognition system such that optimum contrast may be obtained for detection by photo-sensors. An image (U'12) of alphanumeric symbols (U/2) is produced by a convex lens and a slit aperture (S). The relationship between the length (U) and breadth (U) of the symbols in relation to the slit length (S) and width (t) is given by a mathematical formula U/S=v/t=Delta b times a/b(b+Delta b) where a = length from lens to symbol and b = image distance and Delta b = distance of the image from the focal plane of the lens. The image and object distances are related by: 1/a + 1/b = 1/f where f = the lens focal distance.

Title: Weldable foil packaging installation - has objects inserted between inclined foil webs before surface pressing and welding
Inventor: BECK HANS
IPC: B65B9/02
Filed: 1975-03-19
Abstract: The objects are inserted between two wedge shaped fois running together and forming an upper and a lower foil. During the surface pressing together and subsequent welding of the upper and lower foil sections, the pressure of the guide and conveyor elements tensioning the foil sections in the wedge shaped combination area between them is simultaneously reduced. The upper and lower foils are then adjustable in a longitudinal direction in relation to the guide and conveyor elements and thus capable of being dawn tight up to the limits given by the height of the object to be packaged.

Title: X-ray film casette with contrast enhancement - having film pressed flat between phosphor layers using elastic padding
Inventor: STOFF GERHARD
IPC: G03B42/04
Filed: 1975-03-20
Abstract: The contrast of the X-ray exposure is enhanced, and the amount of radiation exposure reduced, by sandwiching the X-ray emulsion between two phosphor layers, in a special cassette. The cassette has a back plate (5) coated with one phosphor (6) while the other half of the cassette has a padded filling (7) coated with the second phosphor (9). The padded filling ensures an even pressure over the film and intimate contact between the phosphor layers and the film, to prevent loss of contrast and resolution. For improved life the phosphor material is mixed with a hard resin binder. This eliminates any protective coating layer and improves the contrast even further.

Abstract: Process for prepg. sulphamoyl halides of formula (I) comprises reacting sulphamic acids (II) or their metal salts with carbonic acid halides in the presence of dichloromethylene ammonium chlorides (III) R1NH, SO3H (II) R2R3N+=CCl2 Cl- (III) R1-NH.SO2X (I) (R1 = aliphatic or cycloaliphatic residue; X = halo; R2 and R3 are each an aliphatic gp. or together complete a heterocycle). Pref. (II) are formed by reacting R1NCO with H2SO4. (I) are starting materials for plant protection agents, dyes and pharmaceuticals e.g. reaction with anthranilic acid then cyclisation of the resulting o-sulphamidobenzoic acid gives 2,1,3-benzothiadiazin-4-one-2,2-dioxides which are herbicides. Compared with the process of the parent patent, this modification gives better yields and purity, and is simpler and less expensive because COCl2, which is cheaper than the other acid chlorides and produces only CO2 and HCl as by-prods. can be used.

Title: Walking beam or pump control - by timing unit determining percentage of open time of delivery valve
Inventor: DOUGLAS BOBBY LYNN
IPC: E21B47/00
Filed: 1975-05-13
Abstract: An oil well pump which is controlled by a valve in the delivery line which indicates that oil is flowing, and if the oil flow stops, it automatically cuts off the pump, is provided with a timing unit to determine the percentage of oil productive time and to decide on this basis whether the pump can continue to function or has to be stopped. After a certain number of abortive attempts to restart, the pump is shut down permanently. This system responds both to varying production rates of a well and to failures due to mechanical breakdown. The pump always operates at optimum efficiency; the improved utilisation factor saves power and cost.
