Patent DE-2410809-A1 (DE)
Title: Oxygen measurement probe for liquids - having membrane protected cathode as exchangeable unit on threaded anode mounting
Inventor: GAMER GEROLD DR
IPC: G01N27/30
Filed: 1974-03-07
Abstract: The O2 content of liquids is measured by the polarographic method using a diffusion sensitive film in the form of a steel mesh reinforced (PTFE or polyethylene) membrane in the proximity of the cathode and an anode in effective contact with this by means of an electrolyte. The cathode and membrane are formed as an exchangeable unit mounted on the anode. The membrane is brought into contact with a carrier when the cathode is screwed up, this carrier being metal and therefore acting as cathode. The method is esp. used for environmental protection in waste water and effluent outfalls. The device described combines greater mechanical stability with much improved exchangeability of the more fragile components.

Title: Heat recovery between exhaust and make-up streams - consists of several independent heat transfer circuits
Inventor: CUBE HANS-LUDWIG VON DIPL ING
IPC: F24D11/02
Filed: 1974-04-04
Abstract: The system can apply to fresh air and extract ventilation or to other processes requiring heat exchange between leaving and entering streams. A series of heat exchangers is placed in the entering fluid stream and a second series of heat exchangers is placed in the leaving fluid stream. Each exchanger of the first set is connected to one exchanger of the second set by vapour and liquid lines through which a heat transfer medium circulates. The medium condenses in the heat exchanger in the intering stream and evaporates in the heat exchanger in the leaving stream. Each heat transfer circuit operates on a smaller temperature difference than the overall difference and thus the total efficiency is increased.
Patent DE-2416379-A1 (DE)
Title: Metal pipes internally coated with plastics - in continuous plant with walking beam to convey pipes
IPC: B05C19/00
Filed: 1974-04-04
Abstract: The parent patent describes a method of internally coating metal pipes with plastics, by blowing in plastics powder, then air alone, while simultaneously drawing an induction coil along the outside of the pipe. This patent describes an apparatus for this purpose, consisting of a store of pipes, a walking beam device and a lifting beam which receives the pipe from the walking beam and brings it to the inlet and outlet couplings of the air circuit; here the pipes are internally coated with powder frit; then a second lifting beam takes a pipe, again from the walking beam, and raises it to the smoothing station; from here the finished pipe rolls down a roller path to a finished pipe store. Both the internal powder-coating station and the smoothing station have induction coils conveyed longitudinally outside the pipes by a common conveyor. Appts. is economic, rapid and space-saving.

Title: Tubular heater with axial cooling ribs - has ribs which are made of two sheet metal strips suitably shaped and joined together
Inventor: HILLINGER ERICH
IPC: H05B3/50
Filed: 1974-04-22
Abstract: Cooling ribs hold the heater between them, and the heating element is directly embedded in the tubular sheath produced by the two shaped metal parts.

Title: Rinsing valve for glass washing device - reciprocating piston gives time lag for washing and rinsing in same chamber
Inventor: SCHMITZ HERMANN
IPC: A47L15/00
Filed: 1974-08-24
Abstract: A glass washing device with a push down spindle with a brush on top, with a rinsing tube (8) inside, has a water control valve with a piston (12) inside a chamber (16) controlling water fed through a side entry (25), so that if the piston is pushed down very radidly, the water in the lower part of the chamber cannot escape immediately. The piston head (12a) has a channel (21) through it blocked by a non return valve (19) in that direction of flow, so that when pressure in the lower part is excessive, the lip of the valve lifts, and water passes into the upper part (15) of the chamber.

Title: Automatic twisted pair wiring and wrapping mechanism - wraps joints of two twisted pair leads and lays twisted pair along defined paths automatically
Inventor: STEINER EWALD
IPC: H05K13/06
Filed: 1974-09-20
Abstract: The wires are twisted simultaneously round a pair of contacts (4) with the insulation being broken by the sharp edges of the contacts. Both wires are fed from rolls of wire (2) through a twisting and laying head (3), which is turned to twist the wire as it moves across the wire laying field; so as to leave the wire lying neatly between rows of contacts, which act as a conduit. The heat (3) is described in some detail. It consists of two pairs of counter-rotating heads through which the wires are fed sequentially, so that the first pair wraps the first pair of contacts, the head then moves, rotating as it does so, and the second pair wraps the final pair of contacts.

The spacer piece can be between an adjusting screw (4) and the bearing, and can be in the form of a wedge.
Patent DE-2453931-A1 (DE)
Title: Button with hollow shaft for snap fastening - has separate reinforcement peg fitting into shaft from above
IPC: A44B1/34
Filed: 1974-11-14
Abstract: The button, for use with articles of clothing, is provided with a button plate supported by a shaft having a longitudinal cavity into which a separate peg is inserted from the top of the button plate. The peg fits on the underneath of a disc which covers the entire upper face of the plate to which it is connected by an articulated tab around the edge. The shaft of the button is resilient allowing its diameter to be reduced to enable a snap-fastening with the mating part whilst the peg is designed to fit in to prevent any reduction in size and thus loss of button once it has been fixed. The peg does not have to penetrate the material which is particularly advantageous where linings are used.

Title: Anti skid brake system - has brake pressure restricted by regulator dependant piston which throttles fluid flow
Inventor: ROSANOWSKI OSWALD JOSEF
IPC: B60T8/74
Filed: 1975-01-28
Abstract: The anti skid system consists of a housing containing a sliding piston provided with two sleeves. A safety ring limits the piston movement and a spring provides its return force. An adjoining housing contains either a hydraulic, pneumatic, mechanical or electronic regulator of which no details are given. During the braking process, brake fluid enters housing bore and flows into a groove provided in the piston and out via a second bore in the housing to the wheel cylinder. As the rod wheel loses speed, the unspecified regulator in the housing takes effect and displaces the piston to progressively restrict the hydraulic passage.

Title: Braided bread dough structure prodn - for subsequent baking from dough extrusion
Inventor: HAFFA WALTER
IPC: A21C11/00
Filed: 1975-03-22
Abstract: In the production of dough ropes for making finish-shaped dough structures ready for baking to braided bread, by a pretreatment of the subdivided dough pieces consisting of kneading, raising (fermenting) and rolling out lengthwise and a further processing to form the dough ropes, single pieces of dough having the total weight of the finished dough structure are separated off and are calibrated after the pre-treatment and then subdivided longitudinally with simultaneous rolling to shape to form the dough ropes for the appropriate dough structures. Ensures that deviations from the standard weight of the product are minimised by always forming this from a single piece divided into e.g. two parts before braiding on twisting together rther than cutting these parts separately from a long dough rope.

Title: Water separator for vehicle fresh air intake - with sandwich of fine and coarse mesh for min. airflow resistance
Inventor: MICHEL FRANZ
IPC: B01D45/06
Filed: 1975-11-05
Abstract: The air intake ducts the air to a sandwich of a fine mesh in frontof a coarse mesh. Both meshes are angled towards the airflow. The first mesh splits the air droplets into a fine moist which collects on the coarse mesh and runs down to a collecting tray. the meshes do not impede the airflow as much deflector plates, and the collected droplets are less likely to be dragged back into the airflow. For improved effect a second sandwich is spaced behind the first, followed by a water gutter for collecting droplets from the roof of the system. The water separator is fitted above the windows of buses, and can deal with a large throughput.
