Patent DE-1803254-A1 (DE)
Title: Baking oven for bread
Inventor: KRAFT GOTTFRIED
IPC: A21B1/50
Filed: 1968-10-16
Abstract: Oven for lye-treated pretzels operates with a hearth plate and perforated tray set flat and removed. The results is an accumulation of lye scale on the tray, as the pretzels are baked first, followed by bread and then black bread. To avoid scrubbing the tray a bottom-closed sheet is placed under the tray, between this and the hearth plate. This sheet is of metal, cleans easily and is re-used several times a day. This sheet should be twice as long as the tray and as wide, so that a single sheet is needed for two trays, the sheet projecting beyond these to avoid lye dripping onto the base hearth. The sheet should have rims on three sides to keep lye off the hearth. One of these rims should have a grip point for the tool used to handle it.

Title: Gas spray metal refining apparatus
Inventor: GLYN DAVIES DAVID ROBSON
IPC: C21C5/56
Filed: 1969-04-19

The gas jet ring is provided with scraper mechanisms for keeping the jet orifices clear of deposited metal.
Patent DE-1925470-A1 (DE)
Title: Stirrer construction for silos
Inventor: SAXLUND ODDMUND
IPC: B65D88/68
Filed: 1969-05-19
Abstract: A stirrer and conveyor device, particularly for large silos, which consists of a central shaft having one or more hubs attached thereto, to each of which is fixed one of more stirrer arms consisting of one or more stirrer arms consisting of one or more bars or rods of a glass fibre reinforced polyester or other suitable reinforced plastic, within a flexible wear-resistant plastic sleeve or tube. The stirrer arm may be designed with a special shape, which would either require a thicker core of reinforced plastic than was necessary or an unduly thick outer layer of wear-resistant plastic, and in such a case, a filler strip of wood or other resilient material is used. An assembly of rods within a common outer sheath may be used and such an assembly may also incorporate filler rods or strips, as already described. Each rod may carry its own separate sheath and this rod assembly may then be fixed together. The substitution of wood or metal stirrer arms by reinforced plastic, enables a large weight reduction to be achieved in stirrer arms for large diameter silos, without risk of breakage, whilst enabling the profiled to be designed particularly for the type of material to be treated.

Patent DE-2019362-A1 (DE)
Title: Laminated welded pipe production process
Inventor: ZIEMEK GERHARD DR
IPC: B21C37/15
Filed: 1970-04-22
Abstract: High pressure pipes will laminated walls are produced by forming a metal strip longitudinally round an open joint inner tube. This is followed by welding together of the outer tube, drawing it down so as to fit on tightly over the inner tube, the process being repeated several times. Pref. the longitudinal seams of successive tubes formed are offset angularly relative to each other. This method is considerably cheaper than the coiling method of generating laminated tubing.
Patent DE-2027881-A1 (DE)
Title: Slide mounted inter changeable casting pipes -for melt transfer - in continuous casting plant
IPC: B22D11/10
Filed: 1970-06-06
Abstract: Device for the renewal of melt transfer from an intermediate vessel to the casting mould in the interval between which melt remains in the vessel, comprises at least two units consisting of a slide, to which is attached a casting pipe.

Patent DE-2040751-A1 (DE)
Title: Walking beam design - for heat treatment furnace
Inventor: KNAAK RUEDIGER DIPL-ING DR
IPC: F27B9/20
Filed: 1970-08-17
Abstract: The moving and fixed beams of a walking beam furnace in which heat is applied from top and bottom consists of water cooled tubes. The lifting beams describe a circular motion, which is transmitted to them by transverse water cooled beams which project through the furnace side walls and are supported on the drive mechanism outside the furnace chamber. The sealing of the passage for the beam through the wall is effected by means of refractory sealing cylinders, the imaginary axis of which is identical with that of the circular motion of the relevent beam, which is passed through them. In the prefd. version the motion is produced by a cam mechanism to which the refractory cylinder is also attached. The design results in minimum cluttering up of furnace chamber thereby facilitating uniform heat transfer.

Title: Tennis racket has extruded profiled metal frame and plastics handle - the latter having a polyurethane foam core
Inventor: VAUGH GEORGE A
IPC: A63B49/08
Filed: 1970-08-28
Abstract: A tennis racket comprises a frame, especially one made of an extruded metal profile, whose spaced end sections are connected by a heart-shaped wedge piece and whose ends are connected by a plastics handle. The handle has a core made of plastics foam, pref. polyurethane. The plastics foam core ensures an even spread of the flexural moment over the entire length of the handle at the moment of impact of a ball on the racket. In this way, vibrational effect with consequent risk of breakage or racking is minimised.

Title: Manganese dioxide-coated condensers - treated with nitric acid before after-forming to prevent deterioration in impedance
Inventor: HASELMANN INGBERT DR RER NAT
IPC: H01G9/00
Filed: 1972-03-06
Abstract: In the prodn of an electrical condenser by forming a dielectric oxide coating on an electrode of valve metal, producing a semiconducting MnO2 coating on this and forming again, the MnO2 coating is treated with HNO3 before forming again. This eliminates or considerably reduces the deterioration in electrical impedance during operation or artificial ageing. Treatment is carried out with dilute HNO3 (1:1 mixt. by vol of conc. HNO3 and H2O) near its b.pt. for ca 10 min. After treatment the MnO2 coating is dried at 200 degrees C. When several MnO2 layers are produced, treatment is carried out after the prodn. of about every fifth layer.

Patent DE-2344298-A1 (DE)
Title: Filter coffee maker with heater for correct temperature - comprises filtered coffee container enclosed in vessel contg boiling water
Inventor: LEPPER WILHELM DR-ING
IPC: A47J31/057
Filed: 1973-09-03
Abstract: The filtering device and the collecting container for the filtered coffee are completely or partly enclosed by boiling water which can be used for both brewing the coffee and keeping it hot. The amount of water above the filtering device is that which is necessary for making the coffee, which is carried out by opening the top or side of the filter chamber. The coffee leaves the supply container through a pipe running through the lower water zone and this pipe may also have a branch which allows the hot water to flow through a mixer with the coffee and then out into the cup set beneath the machine. The coffee is thus kept at the right temperature without boiling over or losing its flavour.
Patent DE-2345658-A1 (DE)
Title: Blanking press for magnetisable parts - with a magnetic conveyor for removal of blanks

Title: Carpet cleaning machine with fluid applicator - has rotary brush and vacuum head behind applicator
Inventor: COLLIER SYDNEY WELLINGTON
IPC: A47L11/20
Filed: 1973-09-24
Abstract: A nozzle extends below the wheels (14) and brush (21) and is shaped to form a skid on which the free end of the head rides to ensure positive pile penetrating contact with the carpet to maximize the effect of the vacuum. The nozzle has two parallel spaced apart walls (15' and 17) which are joined on three sides to form a chamber and the fourth side which is open forms a narrow elongated opening (18) adjacent the rug. Fitted over the opening is a channel-shaped nozzle shoe (30) with opening (31) matching opening (18). Shoe (30) is held in place by bolts (32) and is sealed by a silicone sealant to prevent leakage so that the full effect of the vacuum is felt at opening (18). Shoe (30) aids in the smooth passage of the nozzle over the carpet surface as it presses into the pile. Centrally located on the closed side opposite opening (18) is a hose (19) which is in communication with nozzle (16) through which the spent cleaning fluid and dirt is vacuumed into a recovery tank.

Title: Mechanical-electrical transducer system - has a mechanical or hydraulic sensing element and a transducer proper
Inventor: ROESSLER LUDWIG-KARL
IPC: G01L19/00
Filed: 1973-10-04
Abstract: The transducer and sensing parts are separable, but are firmly joined together for a test process. The sensing element is joined to the object by a flange, by screwing, clamping or locking together. The sensing element has a displacement pickup as transmission element to which corresponds a displacement transmission element in the transducer proper. They are firmly joined together when the sensing element and transducer proper are assembled.
