Title: Photoelectric glass coating inspection - using blue and IR filters for incident light and automatic rejection device
Inventor: ATKINSON EVERETT J
IPC: G01B11/06
Filed: 1973-01-03
Abstract: A photoelectric rig to inspect whether the basicity of a coating on the inside of a glass ampoule of high alkali content has been neutralised, includes a light source which produces an intermittent beam of light passed through the ampoules on a conveyor belt. A photocell receives through filters (IR and blue) only light, restricted to a wavelength band which applies to light dispersed, adsorbed or reduced by the deposit of neutral salt (Na2SO4) on the inner surface. Inspection is more precise than visual methods. Effective neutralisation is clearly discerned. Defective ampoules are automatically rejected.

Title: Turning over crusts deposited from crystallising liquors - by wire grille displaced mechanically in vertical and inclined planes
Inventor: TESSMER GEORG
IPC: A23G3/00
Filed: 1973-06-20
Abstract: Mouldings cast from a crystallising liquor into formers shaped in starch powder in mould boxes, are turned over during the crystallising process by means of a grille arranged at the turning station above the mould box. The grille has rods spaced out to suit the pitch of, and fewer in number than the formers posted in a row in the mould box. A carriage moving in guides supports the grille so that it can be displaced vertically to submerge the rods into the mass of powder between the mouldings, as well as laterally in the plane of the rods and transversely to them. This method effectively replaces handwork and ensures high output with very little scrap.

Title: Mincing machine operating in vacuo - with rotating pan and rotary cutting blades
Inventor: MUELLER HELLMUT
IPC: B02C18/06
Filed: 1973-09-22
Abstract: In the machine both the pan and the blade supports are covered by a transparent hood.

Title: Steam winch reverting and speed control valve - is connected to return cylinder supplied with exhaust steam
Inventor: THAETER HANS
IPC: B66D1/10
Filed: 1973-12-05
Abstract: The valve is moved by a lever from a central rest position into one or the other working position. It is connected to a return cylinder, whose piston is subjected to the supply steam pressure in the rest position on both sides. however when a slide valve is moved into a working position, the return piston is subjected to pressure from an exhaust steam pipe tending to thrust the valve the other way. A valve rod can be connected directly to the return cylinder, or via an intermediate lever. Throttles can be fitted in the pipes delivering supply steam to the return valve. In the supply piping to the return cylinder a slide valve can be incorporated, actuated by the return cylinder so as to cut off the supply steam to the cylinder on the side connected to the exhaust steam pipe on movement of the return piston out of the rest position.

Title: Cast metal parts - for the vibrating parts of motors and machine tools
Inventor: KAUDERER ALFRED
IPC: C21C1/08
Filed: 1973-12-22
Abstract: The vibrating parts of motors and machine tools are usually constructed of steel shaped by rolling, pressing, extruding or drawing of the semi-product.

The holes for the suspension hooks are from 1 to 10 cm apart.
Patent DE-2418093-A1 (DE)
Title: Spray head for ink jet printer - has several jets whose outlet openings have projections arranged about circumference
Inventor: RITTBERG EILT-HEYO DIPL ING
IPC: B41J2/20
Filed: 1974-04-13
Abstract: The inner surfaces of the projections serve as flow surfaces and extend the jets. The projections have side and leading surfaces; the latter running parallel to the surface of the spray head and forming the separation plane for drop formation. The side surfaces can for example be inclined to the surface of the spray head and are contoured to merge into the surface of the head. These surfaces convey the returning flow of excess amounts of spray liquid, i.e. ink, after ink droplets have detached themselves from the head. This design of head and surface contour ensures that drop formation is not adversely affected by residual ink in the vicinity of the discharge points.

Title: Hologram production and reproduction system - has sets of object and reference waves for production and uses projection waves identical to the reference waves
Inventor: KIEMLE HORST DR
IPC: G03H1/00
Filed: 1974-08-29
Abstract: The system for production and reproduction of a hologram utilises two identical object waves with constant phase displacement and two reference waves to produce two holograms which are then simultaneously illuminated by two reproduction waves, when they are required to be reproduced or projected, which are identical to the reference waves used during production of the holograms is constructed such that the portions of maximum light intensity on one of the hologram layer represent portions of minimum light on the other hologram and vice versa.
Patent DE-2457844-A1 (DE)
Title: Automatic control system for batch filters - optimises filtration cycle length wrt duration of subsequent operations e.g. cleaning
Inventor: ABRAMOW WADIM PETROWITSCH
IPC: B01D37/04
Filed: 1974-12-06
Abstract: In the system in which the suspension passes through a batch filter fitted with a controller which initiates at least one associated operation, and the filtrate passes through a flow meter, the control channel which initiates the associated operation contains an element which calculates the arranged throughput over a period of time as an operational criterion of the filter. The criterion element is connected to the output of the flow meter and integrates its signal, i.e. the throughput over a period of time, and divides the result by the sum of the durations of the filtration cycle and the associated operation. The control channel further includes an optimising device which generates an optimised value for operation of the filter. The optimising device lies between the criterion element and the controller which initiates the associated operation and transmits a signal corresp. to the attainment of the max. value of the averaged filter throughput to the controller. Max. efficiency of utilisation of the filter is attained.

The 3-pyridyl isomer differs from known stimulants such as isoproterenol in that it causes a redn. in arterial blood pressure only at doses much greater than that required for increasing contraction strength etc. The 2-pyridyl isomer also has beta-receptor blocking activity so may be used in treatment af arrythmia and angina pectoris. (I) also inters. for other pharmaceuticals. The daily oral dose for a 75 kg. mammal is 40-150 mg. (I) may be used in human or veterinary medicine.
Patent DE-2510735-A1 (DE)
Title: Roadway substructure frost-protective layer - of ballast of non-foamed plastic or rubber scraps hardened by high energy radiation
Inventor: MORLOCK GUENTER DIPL PHYS
IPC: E01C3/06
Filed: 1975-03-12
Abstract: The frost protective layer is for incorporation in the substructure of roads, and other traffic-bearing routes, where serious damage can result from the effects of thawing after freezing, usually preventable only at considerable expense. Here the protective layer is made up from a ballast of non-foamed plastic or rubber material, in pieces which are subjected to a hardening process by a preliminary intensive irradiation with energy-rich rays. This produces a pronounced reticulation effect, causing the material to harden, and only a comparatively thin layer is needed. No specially rigid bedding layers are needed above it, and very little earth excavation is involved. Old pieces of tyres, and similar rubber scrap, can be used. Heat insulating qualities are not reduced by prolonged water absoption.
