Patent DE-2550085-A1 (DE)
Title: Transportable vibrator for clearing trucks - has electromagnet to couple to metal truck used at mineral workings (PT 24.8.76)
Inventor: SANCHEZ MARTIN ANGEL
IPC: G10K11/00
Filed: 1975-11-07
Abstract: The trucks running on the mine railway are cleared of sticky fragments by coupling a vibrator to them. Usually the vibrator has been connected at a special point of the truck, where one half of a coupling has been fitted for it. In the new arrangement, the coupling is by an electromagnet (2) connected to the vibrator (3). Not only does this render the special fittings on the trucks unnecessary, but it allows the vibrator to be applied at whatever point of the truck current experience suggests is best. The vibrator and magnet are mounted on a wheeled trolley (6) and are operated by mains electricity.

Title: Periodic watering system for pot plants - consists of pump with intermediate storage containers overflow pipes and end float switch connected to electronic circuit
Inventor: GRATZA PETER DIPL ING
IPC: A01G27/00
Filed: 1975-12-16
Abstract: The water for watering the plant-pots is contained in a storage tank in which a pump is immersed. A pressure pipe leads to the first intermediate storage container. An outlet pipe leads from each intermediate storage container into each plant pot. An extension hole can also take water into a stand underneath the pot. The outlet pipe is first closed until the intermediate storage container is filled to the required height. The water then flows through a connecting pipe into the next storage container, and so on. The last intermediate storage container contains a float switch instead of an overflow pipe, the float switch switches off the pump by means of a lead.

Title: Vacuum clarifying filter with precoated paper element - with bypass valve across element allowing precoat slurry to suck in
Inventor: MILLER PETER ANTHONY
IPC: B01D29/09
Filed: 1976-01-21
Abstract: In a horizontal element vacuum operating with precoat, a bypass valve allows vacuum to be applied to the upstream side of the filter element at the precoating stage, to draw in the precoat slurry and form the filtering cake. When the valve is closed the liquor to be filtered is drawn through the unit in the usual way. Used for the continuous clarifying of liquors in the food and chemical industries as a 'polishing' filter to produce optically clear liquors. The simple system of drawing in the precoat slurry to form the filter cake is adaptable to automation cyclic operation.

Title: Cardboard cutting machine with adjustable length of cut - increases or decreases speed of rotation of cutting wheels
Inventor: IVERSEN BJORN
IPC: B26D5/20
Filed: 1976-02-06
Abstract: The input shaft drives through the speed control box (12) the bevel gears (14) and shaft (15) to the drive (16) of the cutting wheels (10). This transmission system ensures that the rotational speed of the cutting wheels is proportional to the forward speed of the table carrying the cardboard which is to be cut into specified lengths.

Title: Hydraulic vehicle brake automatic wear adjuster - limits retraction of piston by frictionally supported stop consisting of annular cap on cylinder
Inventor: BARONNET PIERRE
IPC: F16D65/54
Filed: 1976-03-13
Abstract: A hydraulic actuator for a vehicle brake has a cylinder (3) containing a piston (5) movable outwards against the brake mechanism. Retraction of the piston is limited by a first stop (17) defined on an annular cap at the open end of the cylinder. The cap is supported in frictional engagement with the outer periphery (11) of the cylinder. If, due to brake wear, the piston advances beyond a given limit, it engages a second stop on the cap (15, 21) and moves it and thereby the stop into a new position. Subsequent retraction of the piston under the action of a spring (19) is correspondingly reduced by the new position of the first stop.

Title: Steam calendering machine - having a defined fabric path to give steaming , calendering, cooling and stacking with minimum deflection
Inventor: BIESINGER PETER J ING GRAD
IPC: D06B5/08
Filed: 1976-06-01
Abstract: The steam calendering machine, partic. for tubular fabrics, has a guide roller to deflect the fabric at the hip level of the operative. The fabric then follows an upward and angled path to the rear of the unit through a narrow guide slit to pass between two encircling steam chambers.

Title: Modulation of light beam containing several wavelengths - has beams which are modulated by pressure waves and different beams which are separated by diffraction
Inventor: MAIMAN THEODORE H
IPC: G02F1/11
Filed: 1976-12-20
Abstract: The light beam is modulated with separate tv signals in one single acousto-optical modulator. The modulator is excited by pressure waves at different am frequencies in accordance with the separate tv signals, so thaa group of collinearly modulated beams with different wavelengths is diffracted by the modulator. Diffraction of the collinear beams is done with a relatively high efficiency. Simultaneous optical band-pass filtering of tv signal bandwidths is carried out by diffraction of beams produced by cross-modulation, with relatively low diffraction efficiency of the diffraction process for elimination of beams with cross-modulation components. Optical wavelengths are separated in accordance with the tv signal bandwidth, so that the collinear beams and the corresp. the tv signal bandwidths do not overlap.

Title: Mixer for viscous fluids - comprising tube with tangential nozzles inducing alternating rotational flow pattern
Inventor: LEVESQUE GERARD A
IPC: B01F33/40
Filed: 1977-01-07
Abstract: Equipment for mixing viscous fluids comprises a tube with side nozzles A, B, and C. The side nozzles arrive at the inner tube surface almost tangentially, pointing downstream by about 10 degrees. Nozzles B are radial in direction, but point slightly downstream. The fluids moving down the tube are split into substream by nozzles B, and rotates by nozzle A, C. To improve mixing nozzles A, C point in opposite directions. The fluid inserted through the nozzles may be one of the components, or may be a gas such as air. The mixer is partic. suitable for preparation of foamable resin compositions, esp. those containing reinforcing fibres. For such materials, mixing must be rapid prior to moulding. Prior mixers have incorporated baffles leading to dead spots and difficulty in cleaning.

IPC: H01L21/20
Filed: 1977-02-11
Abstract: Appts. consists of a reactor with two fcing discs, each with its own gear motor drive. One disc carried the substrate wafers and the other carries two sources of p-type and n-type semiconductors. The drive motor of the upper disc has also a feedscrew mechanism to vary the distance between the two discs. Heaters are arranged to produce an isothermal temp. field parallel to the active surfaces of the discs. The amt. of material, applied to a substrate in alternate layers can be controlled very precisely within a range 50-10000 angstroms. The accuracy and the lower doping limit does not depend on the reactor volume or on the number of simultaneously treated substrates so that a high throughput is ensured without quality deterioration. Solid monolithic and powdery semiconductors are equally suitable as sources.
