Patent DE-2416600-A1 (DE)
Title: Plastic barrel head and base ring - has U-section rolling ring portion with transverse radial stiffening ribs
Inventor: HAMMES THEO
IPC: B29C49/20
Filed: 1974-04-05
Abstract: The previously prepared rings are inserted in recesses in one of the blowing mould halves so that their halves protrude from it and form with it during the extrusion process a free passage for the hose below the blowing nozzle. When the mould halves are assembled the free portions of the rings slide into mating recesses in the other half, and the axis of the hose squeezed in the process runs through the ring centres. The rolling ring extends from each ring in the radial and axial direction and is of U-section, and its inner shank extends upwards further than the outer one. The inner shank forms an extension of the anchoring shank welded to the barrel side, which also joins via a curve onto a horizontal anchoring shank welded to the barrel top or base. The inner, outer and base shanks of the rolling ring are joined to each other and to the horizontal anchoring shanks by radial transverse ribs.

Title: Electric hot plate baking unit - plates rotate about central shaft to bake several steaks etc.
Inventor: KRAMER HANS
IPC: A47J37/04
Filed: 1974-05-14
Abstract: A number of electric hot plates are mounted on a common support, which is mounted to rotate about a central vertical shaft so that several omelettes, steaks, etc. can be baked at once by a single cook who can rotate the stand to bring the hot plates into position. The plates are evenly distributed about the vertical shaft at a radial distance, whilst a stationary heating unit radiates heat downwards to the side of the vertical shaft and t a distance above the hot plates. The baking process is speeded up since the food is cooked from both sides. A drive mechanism with an electric motor can rotate the shaft.
Patent DE-2423741-A1 (DE)
Title: Stressed concrete reinforcing-wire-cluster anchorage - with additional reverse holes in disc to anchor outgoing individual elements

Patent DE-2440181-A1 (DE)
Title: Ozonising fluids, drinking water, sewage by molecular filter - zeolite particles charged with ozone and regenerated by heat
Inventor: JACOB GERNOT
IPC: C02F1/28
Filed: 1974-08-22
Abstract: Fluids, possibly carrying suspended solid matter, are ozonised by means of gas adsorbent particles. A mixture of a carrier gas and ozone is caused to flow through a mass of the particles which take up the ozone molecules into their pores, and are then transported by a conveyor to a reaction vessel. In this, as the fluid flows from below upwards, the adsorbed ozone is given up, and the ozone-free particles are then dried and recharged with ozone. The particles comprise molecular filters such as zeolites, particles of silica gel, active carbon, porous metals, ceramics, etc. Ozone alone may be used to charge the particles, and the flow in the reaction vessel may be from top to bottom. Gas losses are reduced to the minimum. Only a small amount of ozone is required, and it may be used without a carrier gas, 100% pure. The zeolites can be regenerated at 200 degrees to 400 degrees C, and flushed through with dry nitrogen or air.

Title: Electronically self-locking switch has three divider flip-flops - has interconnected clock input to reset input, and has reset programming diodes
Inventor: SCHIEBELHUTH HEINZ
IPC: H03K17/56
Filed: 1974-09-10
Abstract: The electronically self-locking switch, for radio and television equipment, has flip-flops (1, 2, 3) acting as binary dividers whose clock inputs are supplied with a pulse when an external switch is operated. Each flip-flop has a reset input (13) connected to the clock inputs (4 etc.) of the other flip-flops. Diodes (28, 29) are used to programme mutual resetting and are connected between the clock and set inputs. Lamps (30 etc.) indicate the output conditions of the flip-flops. The advantage lies in the circuit allowing not only all switch states to be reset on operating one switch but also individual switch states.

Title: Metal installation flange for double glazed panels - is suitable for use with replacement panels in existing frames
Inventor: PEETZ HANS-DIETER DIPL ING
IPC: E06B3/54
Filed: 1974-09-12
Abstract: The method of mounting is for a double glazed window panel, especially suitable for use when replacing existing single glaxing where traditional methods may not be sufficiently strong for the increased weight. One of the sheets of glass (1) is made larger than the other (3) to form a peripheral projection and the two sheets are sealed (4) together around the edges. The fixing method consits of bonding (5) a piece or pieces of sheet metal (8) around the projecting edge of the larger plane and to the seal so as to form a projecting flange or a number of projecting portions which can be drilled (9) to take screws for affixing to the frame (2). Various shapes of flange for internal and external fixing are possible and malleable metal may be used so that the flange may be bent out to fit the frame on site.

Patent DE-2461904-A1 (DE)
Title: Curved door lock safety rod - is hung over handle shank to pass through key handle hole
Inventor: FLECK GUNTHER
IPC: E05B13/04
Filed: 1974-12-31
Abstract: The door lock safety device is a metal rod bent in the form of a walking stick. The hooked part of the rod is hung on the door handle shank and the straight part passes vertically through the hole in the key handle. This rod type safety device is made from a material which is difficult to bend such as aluminium or steel. On locking, the key is left into the keyhole and rotated so that the safety locking rod device can be readily pushed through the key handle hole. This restricts the rotation of the key so that the locks cannot be opened by picking.

Title: Motor vehicle hydraulic brake system - has hydraulic power booster with integral pressure reservoir for emergency application
Inventor: BACH LOYD GENE
IPC: B60T13/12
Filed: 1975-02-21
Abstract: The hydraulic brake booster has a main housing with inlet for pressure medium from supply source and return pipe to reservoir. A foot operated device controls a valve providing connection between inlet and return pipe on one hand and the inlet and pressure chamber on the other one. A piston moving in the housing bore defines a chamber, into which it is resiliently engaged. The chamber is coupled to the inlet by a pressure relief valve on a preset pressure gradient between them. Part of the pressure medium supply is deflected from the inlet into the chamber via a valve responding to the pressure relief valve actuation, as well as to the failure of pressure medium supply to the inlet, in order to connect the emergency pressure medium reservoir to the chamber.

Title: Jaw type oil and gas well preventer - has slotted reinforced elastomer jaws in converging guides with power ram
Inventor: ARSUMANOV SUREN AKOPOVITSCH
IPC: E21B33/06
Filed: 1975-07-02
Abstract: A jaw-type preventer for oil and natural gas wells has guides for the two jaws which converge from the outside towards the central passage which is to be sealed. Each jaw consists of two lateral metal parts which are joined by an elastic medium. The latter has embedded reinforcing plates towards the central passage, separted in the open position from each other by slots. A hydraulic cylinder at each end actuates the jaws. This is a simple design which combines small height with adequate strength. It ensures a hermetic seal against tools of any diameter and shape and does not impede round-tripping when the well mouth is sealed.
