Title: Ring piston for vehicle transmission clutch - has radial return springs moved by hydraulic fluid
Inventor: HENSEL WERNER DIPL ING
IPC: F16H57/08
Filed: 1975-05-17
Abstract: The ring piston (1) is used in automatic transmissions for motor vehicles, and has return springs (11) trapped between the piston and spring retainer caps (9) on the housing. There are sealing rings (2, 3) on one end in slots (4, 5), and a circular recess (6) at the other end providing an opening (7) for the lug (8) of the spring retainer cap (9). A fastening device (14) in a groove (12) in recess (6) supports the return springs around the piston (1) circumference and produces an initial compressive stress. The fastening device is a ring of wire. The ring piston (1) is subjected to hydraulic fluid pressure through canal (20) and this releases the friction coupling of the clutch by counteracting the return spring force. Releasing the pressure during declutching moves the springs in the reverse direction.

Title: Knitted plush fabrics having pile knotted into ground - produced on double latch needles in circular machine dial
Inventor: NUBER OTTO
IPC: D04B1/02
Filed: 1975-08-07
Abstract: The fabric consists of a ground and a plush thread forming loops which are anchored into the stitches of the ground fabric. The plush thread is drawn in a loop through the stitches of the ground fabric and is bound in by being slung around the two legs of each stitch and pulled tight, so that the plush thread is, as it were knotted in the stitches of the ground fabric, with vertically standing loops which may be cut. A row of stitches of the ground fabric is first of all laid in and these ground thread stitches are pushed back on the needles. Then, in the zone between needle hook and ground thread stitch, a plush thread is laid on the backs of the needles, and pulled into plush loops; these loops being dranw through the ground fabric stitches. The ground fabric stitches now slide back towards the needle head, and finally the plush thread loops are pushed over the needle heads with moderate tension and pulled tightly in. The plush pile stands verticaly to the fabric and is firmly bound in without too much pile material being worked into the ground. There is no need for further treatment to fasten the pile in, and the fabric can be used for all purposes.

Title: Cable layer with friction drive to cable drum - coupled to road wheels of trolley pays cable out at exactly correct speed
Inventor: FOECKERSPERGER WALTER
IPC: H02G1/06
Filed: 1975-08-11
Abstract: The cable laying trolley is particularly intended for the installation of less robust forms of cable, for example coaxial cables, where axial forces must be avoided in order to prevent damage. This difficulty is overcome by providing a drive to the cable drum from the road wheels in order to dispense the cable as the trolley is drawn forward. Friction drive wheels are mounted on the end of an arm attached to the trolley chassis, and which can swing away from the cable drum axis to allow drum changing. A gear drive joins the road wheels to the friction wheels, the latter driving the drum by pressing against the cable.

Title: Microwave sterilisation of food - using very steep microwave pulses of short mark to space ratio
Inventor: FRITZ KARL DR
IPC: A23L3/01
Filed: 1977-03-22
Abstract: Food is sterilised by microwaves which act on it as pulses with a very short mark-to-space ratio. The amt. of emitted energy is so dimensioned that a steep temp. gradient with a maximum temperature, which does no harm to vitamins, hormones or flavour, is followed by a steep cooling gradient. The steep gradients donot give the microbes time to adjust the osmosis through the infusorial wall to the changed conditions. They are therefore killed at a lower max. temp. (70 degrees C in the case of milk).

Title: Steering or tracking system for guided missiles - has semi-transparent mirror and two dimensional light transmitter for generating target mark
Inventor: OPPELT FRIEDRICH HANS
IPC: F41G7/30
Filed: 1977-06-08
Abstract: The arrangement for steering or tracking a missile uses a reflected target mark on a semitransparent mirror in the user, field of vision. The target mark is brought to coincidence with a target whence coordinate signals are derived which indicates the position of the target in the field of vision. This arrangement can be used to steer a missile launched from an aircraft onto a aerial target. The missile is tracked after its launching. Even though the projectile has a homing head it is necessary to inform the projectile about the required target. Coordinates of a target are established reliably and by relatively simple means. The coordinate signal system is controlled by the user. A two dimensional light transmitter is controlled by the coordinate signals and generates an illuminated target mark. An image optical system generates the target mark by the semitransparent mirror at infinity and reflects it into the field of vision of the user.

Title: Reaction time reduction - for biological treatments by superimposed alternating or steady magnetic fields
Inventor: HIRCHE ERNST DIPL ING
IPC: C02F1/48
Filed: 1977-07-09
Abstract: The reaction times of biological, chemical or physical sewage treatments are reduced by applying an alternating or constant magnetic field. Apart from the treatment of sewage and industrial wastes, for all bioproduction processes in breweries, and the pharmaceutical industry, for the treatment of water for process purposes or drinking water. This requires little extra expenditure because the magnets can be connected directly to an ordinary 220 V or 380 V mains supply at 50 Hz. Suitably a coil to produce a magnetic field is encapsulated in polyethylene. It has a diameter of 200 mm. and a length fo 200 mm. and is immersed into an aeration basin for activated sludge. The process treatment time is considerably shortened thereby and the total volume required is reduced thereby.
