Title: Reflex viewfinder for photographic cameras - has direct viewing or parallel observation options and pivoted mirror and inverting prisms
Inventor: SZIGRISZT LASZLO
IPC: G03B19/12
Filed: 1974-07-25
Abstract: An interchangeable viewfinder for photographic cameras is constructed such that a pivoted mirror is attached which has in the path of the shaft of light reaching the ground glass observation plate and also lies parallel to the objective axis. In one position the mirror reflects the light forming the image observed on the ground glass viewing plate onto two prisms so that the image produced on the plate can be observed in an axis parallel to the objective axis. In its other position the mirror does not interfere with the light shaft originating from the objective and observation can then be directly by means of a second ground glass disc perpendicular to the objective axis. Instead of being two investing prisms, two plane mirrors may be used for image diversion.

Title: Casting grabbed and removed from mould by cranked arm - and tongs advancing longitudinally with ejector and pivoting transversely
Inventor: MAERGNER H-CHRISTIAN ING GRAD
IPC: B22D17/20
Filed: 1974-09-26
Abstract: A device for removing a casting from a pressure-casting machine, which comprises a movable and a fixed machine plate and an ejector slidably mounted in the movable plate, comprises a grab mechanism with a mechanically, hydraulically or electromechanically operated tongs; the grab mechanism is integrally connected to the ejector in the direction of travel of the ejector. Pref. the grab mechanism comprises a cranked arm, rigidly keyed to a shaft which is parallel to the direction of travel of the ejector (which in turn is perpendicular to the plane of the drawing), this shaft being slidably mounted in a bearing block which itself is mounted upon the moving mould plate. Thus, as the ejector moves transversely to the plane of the drawing to eject the moulding, the grab arm advances with it by axial sliding of the shaft. relative to tis supporting bearing block on the moving mold plate, the arm being pivoted to swin in between the fixed and moving parts of the mold in synchronism with the opening of the mould, whereupon the grab seizes the moulding or casting and then swings out to remove it from the mould. A hydraulic or pneumatic cylinder is pref. used to provide the pivoting action. The only motion applied to the grab device, other than the opening and closing of the jaws, is the pivoting action causing it to swing perpendicular to the direction of travel of the moving mould plate and ejector.

Title: Miniature relay for printed circuit boards - has plastic side-plates with lugs protruding beyond casting resin encapsulation
Inventor: PFEIFER JOERG
IPC: H01H50/02
Filed: 1974-09-27
Abstract: A miniature relay for connection to a printed circuit board consists of a rectangular metal casing which is open at the end towards the printed circuit board. Two plastic end plates line the inside of the two narrow faces and terminate in small lugs protruding outside the housing and outside the layer of casting thermosetting resin which closes the open end of the housing. This ensures a precise and stable spacing of the metal relay housing relative to the conductor tracks of the printed circuit board. It makes the mounting independent of slight menisci which may form on the casting resin around the connector pins.

Title: Dough depositing machine - with proximity switches for spacing and limit switch for cantilever belt retraction (NL080676)
Inventor: SCHNEE WALTER
IPC: A21C9/08
Filed: 1974-12-03
Abstract: An automatic machine for the deposition of lumps of dough into dough raising baskets consists of the cantilever end of an endless belt which is moved forward when a loaf passes a proximity switch and stopped when it passes a second proximity switch. The discharge drum of the cantilever end is attached to an endless chain drive which is set in motion when a loaf passes a limit switch. All loaves are discharged into the baskets which are arranged under it at the same spacing as the cantilever end is run back to its feed end. This replaces many successive limit switches by one single switch; this eliminates trouble by faults in trailing cables. An easier adjustment of the spacings becomes possible.

Title: Spike remover for tyre - with hollow shaft cutter to fit round spike and mill away spike head
Inventor: DUBITSCHER AXEL
IPC: B60B15/06
Filed: 1974-12-06
Abstract: A spike removal tool has a hollow shaft (1) with a profiled cutting edge (6) which is positioned over the spike (3). As the tool is rotated it separates the spike from the tyre material, with any swarf thrown out through holes (8) in the side of the shaft. A thin layer of rubber is left between the spike and the tool to secure them together. When the tool reaches the spike head (5) the whole spike can be removed by levering sideways. The tyre is not damaged and a new spike can be re-inserted. The tool is fitted to any convenient drill, either bench mounted or portable, and enables an operator to remove spikes at a rapid rate.

Title: Aq. dispersions of polyolefine fibrids - opt. mixed with cellulose fibres, prepd. by using polyoxyalkylated sulphated alcohol dispersants
Inventor: FIKENTSCHER ROLF DIPL CHEM DR
IPC: C08J3/05
Filed: 1975-06-26
Abstract: The dispersions are prepd. by dispersing the fibrous prods in the presence of a dispersant. Dispersant consists of polyoxyalkylated sulphated alcohols contg. 1-6 structural units having formula -C-O- (CH2CH2O)x (CH2CHMeO) SO3M(I) (where x = 0-30; y = 1-35; M = Na, K or NH4+ and Me is methyl). The fibrid dispersions can be processed to paper or textile-like sheets and webs. Used of (I) prevents foaming and agglomeration on distn. of fibrid dispersions and in sheet formation, esp. on paper machines. Fibre-bonding and initial wet-strength of webs obtd. is improved. Small quantities of (I) are sufficient to disperse the hydrophobic fibrids in water. In an example, high density polyethylene fibrids were mixed with sulphite pulp in water. Dispersion was added to a sheet-former contg. water. 1% CH2O 2 - (CH2-CH2O)38(CH2CHMeO)4o (SO3Na)2 was used as dispersant. The sheets obtd. had wt/area 130 g/m2, initial wet strength 70g. Foaming on distn. and sheet-forming was weak. No sheet could be formed in absence of (I).
