Title: Magnetically polarised tubular gas laser - has subsystems with capillary producing field and element orientated in field
IPC: H01S3/03
Filed: 1976-03-22
Abstract: Gas laser of magnetically polarised tubular design is compact, rigid and has a long life span. It consists of three laser subsystems which are each separately tested. The subsystems are formed by a suction stem which contains the cathode conductors and getter, the cathode casing (17) with a cathode and a laser capillary with an anode and end piece, such as mirrors, booster windows etc. The permanent magnetic field is applied to the capillary and is intended to polarise the light emitted by the capillary. The laser element is rotated inside of the magnetic field until the field is parallel to the maximum direction for polarised light that is emitted. This is used to orientate the laser element inside the magnetic field. There are two magnets each with a field at a right angles to the longitudinal axis of the capillary.

Title: Application of aphrite from sugar refining as fertiliser - by spraying or sprinkling
IPC: A01C23/00
Filed: 1976-07-08
Abstract: Aphrite, a form of calcite (CaCO3) formed as a by-product in sugar refining, is applied as a fertiliser and soil improver by spraying or sprinkling it over the land. The aphrite can be used directly from the drum filters in which it is sepd. from the refined juice, without intermediate drying. The moist aphrite from the drum filters is slurried with water in a mixer, and the resulting pumpable slurry is transported to the site of application in a tanker. It can be applied by means of a conventional liq.-manure spreader.

Title: Carpet coiling mechanism onto tube - has arms with components engaging in tube sliding on transverse bar
IPC: B65H18/20
Filed: 1977-02-09
Abstract: The mechanism coils a carpet onto a tube, and has a unit opposing movement of the tube, into whose ends components of it fit. These components are mounted on the ends of arms sliding on a transverse bar, and which in turn is supported by arms hinging in the frame. Thus the unit rises as the diameter of the coil on the tube increases, and counterbalancing devices are provided to take its weight when it is freed from the tube, in order to allow removal of the roll of carpet on the latter. The unit can have cones fitting in the tube ends, mounted on arms sliding on the bar.

Patent NL-8000927-A (NL)
Title: Record player pick=up arm - uses small stylus pressure and avoids risk of groove-jumping
IPC: G11B3/12
Filed: 1980-02-14
Abstract: Conventional record plate pick-up arms have the disadvantage that the movement of the disc under the stylus imparts a lifting moment to the pick-up head, making it possible for the stylus to jump out of the groove, unless sufficient weight is added to the head by shortening the distance between the pivot (D2) of the arm (2) and the counterbalance weight (3). This effect is reduced by having the stylus (7) at the rear of the pick-up head on a longer carrier arm (6). The movement of the disc under the stylus then imparts a downwards turning moment (M1) on the stylus which partially counteracts the lifting moment (M2) on the head. This pick-up can thus be used with less head pressure, without the risk of jumping the groove.

The amplifier consists of a pair of emitter-coupled transistors (12,13) fed by a constant current source (21), and an emitter- follower output transistor (17). The amplifier may be in the form of an integrated circuit with the series resonator (11) as the only external component. The resonator can be an inductor and capacitor, or a crystal.

Title: Rectangular-section tunnel steriliser contg. transport chains - is contained in cylindrical jacket held at tunnel pressure during cycling
IPC: A23L3/00
Filed: 1982-06-03
Abstract: The heat sterilising unit for the contents of cans, jars, etc. in wire baskets comprises a rectangular-section horizontal tunnel which is contained in a circumscribed cylindrical jacket and has its projecting ends hermetically sealable by vertically actuated slide doors with inflatable seal rings. The baskets are loaded and discharged in batches each consisting of a continuous row by an endless chain assembly which extends through the entire length of the tunnel and connects with endless belts at the entry and exit (via roller pairs), thus forming part of a production line. The pressure in the jacket is equalised with that (of the steam) in the tunnel during the sterilising cycle to eliminate the need for strengthening the flat tunnel walls. Used as tunnel steriliser for heat-sterilising canned or jar-packed food. The unit is of simple and inexpensive design and permits the use of steam at e.g. 2.5-3 bar without special tunnel wall reinforcement.
