Patent DE-2337976-A1 (DE)
Title: Concrete skip for use with crane - has frame supporting it in standing or lying position
Inventor: EICHINGER FLORIAN
IPC: B66C3/00
Filed: 1973-07-26
Abstract: The skip is equipped with a frame which can be changed over to support it in the standing or lying position. In the former position, the upper cylindrical portion of the skip can be cut off at right angles to the cylinder axis, and in the lying position a cylindrical section in the shape of a cap peak can swing down to form an extension to the cylindrical part and act as a filling funnel. In this position, the skip can be supported in a sliding frame solidly attached to it, with cross-members at front and rear joining its main beams, and inclined struts leading from beams or members to the skip, which are vertical when the skip is upright.

Title: Moisture-impermeable soap powder cartons - cardboard printed with vinyl and/or rubber dispersion on conventional carton-making machinery
Inventor: SCHNEIDER ERICH
IPC: D21H23/66
Filed: 1973-08-17
Abstract: Cardboard suitable for carton making with decreased permeability towards moisture and scents is mfrd. by printing on the surface of the board using solns. or dispersions of synthetic resins as lacquers. The pref. resins are acrylic, polyvinylidene chloride or rubbers, esp. chlorinated rubber or isomerised rubbers contg. chlorinated paraffins and waxes. A single-coat process with e.g. acrylic and polyvinylidene chloride, or a double-coat process comprising acrylic and polyvinylidene chloride resins as first coat and rubber plus waxes as a top coat, can be used on conventional board-preparing; low-pressure printing machinery, followed by cutting and stamping into shape for folding and gluing into cartons. The lacquers can be modified with pigments e.g. titanium dioxide, or with optical bleaches which augment the colour values of printings applied to the coated board. It is used for cartons to contain products which are sensitive to warehousing conditions, especially for soap and detergent powders where ingress of moisture or loss of perfumed additives can degrade te product.

Title: Gas discharge display element - has metal particle paste sintered to form leads and electrodes on ceramic particle plates
Inventor: MILGRAM ALVIN A
IPC: H01J17/49
Filed: 1973-10-11
Abstract: The gas discharge display element forms part of an array of such elements and consists of two dielectric plates, e.g. of aluminium oxide, each containing fine ceramic particles. The top plate has a large cavity to contain the gas, and two countersunk regions at its ends for the ring electrodes. The bottom plate has two fine holes for the conductors leading to the two electrodes in the top plate. The plates are aligned in a press and joined together. A paste containing noble metal particles is screen printed onto the countersunk regions and into all the holes. The plates are then sintered until the noble metal particles and the ceramic particles have formed a monolithic structure. The cavity in the top plate is filled with a rare gas, such as neon, krypton, argon, etc., and the cavity sealed with a transparent window.
Patent DE-2355594-A1 (DE)
Title: Pressure casting machine control - has high pressure booster with stepped piston for finishing pressure phase accumulator
Inventor: EMMERICH VALENTIN
IPC: B22D17/32
Filed: 1973-11-07
Abstract: A pressure casting machine is controlled by separate control circuits for the mould filling and finishing pressure phases. The conventional intensifier piston to produce an adequate press cylinder pressure for the finishing pressure phase has been replaced by a high-pressure charging device with a stepped piston which supplies the pressurized fluid for the accumulator during that phase. A higher pressure casting productivity is achieved by reducing the moving inertia masses. The time required to build up the finishing pressure is reduced, and this time can be adjusted independent of the pressure force. The new system requires less capital expenditure.
Patent DE-2355749-A1 (DE)
Title: Wedge-shaped dovetail for forging machine tool - is angled to avoid use of locking wedge and including securing bolt
Inventor: KUBIAK HANS
IPC: B21J13/02
Filed: 1973-11-08
Abstract: The length of engagement sufficiently long that the taper of the interlocking faces is in the transition zone, nearly self-locking. For security a hole is drilled through the forging machine just beneath the bottom of the dovetail through which a long elastically extensible bolt is passed. At the small end of the dovetail a small collar bears on the machine face. At the large end a collar presses against the end of the tool. With the bolt tightened so that it is flexibly extended it will exert a force tending to press the taper further into engagement. After removing the bolt, a light blow on the small end will extract the tool.

Title: Metering device with stirrer for injection moulding machines - the stirrer being a pivotable, adjustable rod mounted on the stirrer shaft
Inventor: ROSEMEIER DIETER
IPC: B29C48/03

Abstract: A metering device for charging a moulding cpd. into the barrel of an injection moulding machine has an axially mounted, motor-driven stirrer shaft which extends as far as the outlet of the charging hopper and on which a stirrer is laterally fixed. The stirrer is a rod which is pivotably mounted at the stirrer shaft and the angle that it subtends with the shaft is adjustable and may be locked in a desired position. Accurate and even flow of the moulding cpd. is achieved without risk of blocking the hopper outlet. This is independent of the particle size of the granulate being metered.

Patent DE-2452680-A1 (DE)
Title: Mixer valve with two inlets and one outlet - is controlled by valve spindle with inclined taper
Inventor: THOMPSON ARTHUR D
IPC: F16K11/02
Filed: 1974-11-06
Abstract: The base of the valve body encloses the two flexible inlet pipes and the outlet nozzle within which the fluids of different temperatures are mixed. The upper part of the valve body locates the valve spindle and the two clamping arms. The valve spindle has a push and pull action by which the valve can be opened and closed. By rotating the valve spindle in the pulled position, the inclined tapered end of the spindle describes a circular motion which operates the two clamping arm alternatively. This regulates the flow in the two pipes from zero to maximum 180 deg. out of phase. It is thus possible to obtain any mixing ratio required.

Title: Hollow spindle for internal clamping - is expanded by internal hydraulic pressure
Inventor: KOSTYRKA PETER
IPC: B23B31/30
Filed: 1975-04-23
Abstract: The internal clamping spindle consists of a thin-walled hollow sleeve with end cap. The sleeve has longitudinal slis (3) around its circumference. The slits are closed off at the inside by a second sleeve made from a thin elastic material, forming a pressure chamber (7). The length of the slits is limited so that they do not extend over the thickness of the end cap on the sleeve. When hydraulic pressure is applied to the pressure chamber, the sleeve will expand. It is is mounted in the bore of a workpiece, the workpiece will be clamped by the sleeve. The configuration of the slits around the circumference of the sleeve can be modified to vary the degree of flexibility of the clamping sleeve.

Title: Clothes button securing clip of spring steel wire - which passes through the button and garment and springs back to hold button in place
Inventor: KATTA GEB ALBER ROSWITHA
IPC: A41H37/00
Filed: 1975-06-11
Abstract: Clothes button securing clip has a given shape, and can recover its original shape after deformation. The clip is gripped between thumb and index finger, and the two ends are pressed together to the distance between the holes in the button so that they pass through the holes. The button is then placed in the desired position on the material and the two wire ends are passed through the material. When the clip is released, it springs back into its original position, thus securing the button. The clip allows the button to be attached easily and rapidly even by inexperienced persons, e.g. in case of emergency when no needle and thread are available, or for professional use in the clothing industry.
