Title: Spray drying tower, for e.g. wax or detergents - has rectangular spray and square downtake compartment
Inventor: KUERSCHNER HANS
IPC: B01D1/18
Filed: 1977-12-24
Abstract: In a spray drying system for materials such as wax or dispersible substances like detergents, the reactor consists of a rectangular spray compartment adjacent to a square downtake shaft. The material is sprayed in an ascending stream at the bottom of the spray compartment which is joined to the downtake shaft by a slot at the top. Both compartments are fitted at the bottom with a perforated plate through which separately adjustable air streams are blown by ventilation. The flow velocity in the downtake shaft is made less than the min. falling velocity of the formed particles. This requires towers of less height and permits a ready adjustment of the residence time.

Located between lens and point is a diaphragm restricting the cross-section of the beam. The distance of the diaphragm from the point is pref. min. 10%, esp. min. 20% of the distance from lens to the point. Diaphragm pref. has a cooling device and can be centred w.r.t. the beam, esp. for achieving the min. current impinging on the diaphragm. The beam can be sharply focussed on the workpiece in a smaller zone than can be achieved by conventional systems.
Patent DE-2815867-A1 (DE)
Title: Tablet sorting machine - with revolving perforated disc, retainer strip and lateral discharge
Inventor: MORISHITA KAZUO
IPC: B07B1/08
Filed: 1978-04-12
Abstract: A sorting machine for tablets includes a slowly revolving circular plate with perforations, through which undersize tablets can drop. A vibrating mechanism oscillates the whole machine except the loading funnel. Tablets which have not dropped through the perforations are retained by a barrier strip and are ejected continuously sideways. A container for "NO GO" tablets is discharged from time to time. The result is a fast and reliable way of segregating undersize tablets. The separating size can be easily varied by changing the perforated plate.

Title: Machine for bending pressure gauge Bourdon tubes - has spring loaded pawls to prevent slipping of tubes during rotation by hydraulic jacks
Inventor: HARALAMBIEV KRUM GERASSIMOV DI
IPC: B21D7/024
Filed: 1978-08-31
Abstract: Bourdon tubes for pressure gauges are bent to shape on a machine with a roller (3) attached to a turntable (7) which can be rotated by hydraulic jacks (9) about a vertical axis. Two tubes (12) supported by guides are clamped against the roller (3) by jaws (2) fixed to a bracket (1). The bracket is moved by an hydraulic jack (10) and exerts pressure on the jaws so that the tubes are pressed against spring loaded pawls (4) which can slide in radial holes in the roller. These pawls reduce the risk of accident when bending the tubes.

Title: Cleaning system for internal surfaces of chemical plant - uses low and high pressure jets of cleaning liquid in succession
Inventor: NIELEBOCK HANS ING GRAD
IPC: B05B3/06
Filed: 1978-09-16
Abstract: A device for cleaning the internal surfaces of pipes and tanks used in chemical plant consists of an inner pipe which is inserted into the pipe or tank. This inner pipe has a row of radial nozzles which eject jets of cleaning fluid at low pressure over the interior walls. A valve inside the inner pipe opens when the pressure of the cleaning fluid exceeds a pre-set value and allows the liquid to flow to a set of rotatable nozzles which are rotated by the reaction of the jets. These high pressure jets remove the fragments loosened by the low pressure jets.

Title: Radio-alarm clock combination supply adaptor - has mains transformer in flat component and uses flat or round contacts
Inventor: WEISE DOMINIKUS
IPC: H02M1/10
Filed: 1978-12-13
Abstract: The power supply adaptor is intended for a radio- and cassette recorder-radio-alarm clock combination. A flat component part houses a transformer for the mains voltage, the component having flat or round contacts for current transfer. When the alarm clock combination is inserted onto the adaptor, its batteries are switched off, and vice versa. The connection between the adaptor and the alarm clock combination can be formed by a suitable frame, contact pins or magnetic platelets. The adaptor contains a light source in connection with a feeler pin which disconnects the current when the alarm clock has been removed. A mechanical slider, however, provides readiness for new adaptor application. On the rear side of the adaptor is a plug socket for the mains connection. This arrangement permits the utilisation of the alarm clock-radio combination outside the bedroom etc.

Title: Flat display matrix excitation device prodn. - uses insulating plate shaped support for matrix switching cells, with corresponding number of apertures containing conductive suspension
Inventor: MARTEN PETER DIPL ING
IPC: H04N3/12
Filed: 1978-12-20
Abstract: The flat screen type display has a coordinate matrix, at whose modal points are provided switching cells, each generating an electrostatic transverse field. This field accelerates charge carriers parallel to the display plane. On each side of the cells are elements generating an electrostic longitudinal field for charge carried acceleration in orthogonal direction to the display plane, as in 2619139. An insulating plate forms the support for the switching cells, having apertures, corresponding to the number of cells and extending orthogonally to the plate plane. The apertures contain a conductive suspension, with conductive particles having a higher specific weight than the rest of the suspension. Then the support is subjected to centrifugal force, which forms a conductive layer on the aperture walls. These cell layers are then contacted with driver line leads, serving for excitation of the cell. The plate is preferably of vitreous or ceramic material.

Filed: 1979-02-16
Abstract: A tool (41) for holding, screwing-in and unscrewing an anchor bolt (31) or a screw tap is provided with a handle (45) and a shaft (43) fixed thereto. The shaft has essentially the same cross-sectional shape as the shaft (31b) of the bolt (31) or of the screw tap and can be inserted in the shaft (31b) of the bolt or screw tap. The tool shaft (43) is provided with axial projections having a neck and a head which project into recesses in the bolt shaft (31b) when the shafts (31b, 43) are inserted into one another. The two shafts (31b, 43) can be fixed in the rotatory position, so as to be fixed against rotation relative to one another, by means of a sleeve (47) displaceable on the two shafts, in which shafts the projections and recesses produce an axially non-displaceable connection. The tool (41) is used during operations in order to screw an anchor bolt (31) or a screw tap into a stepped blind hole (1d) penetrating the fractured surface (3) of a femur (1). At the same time, the sleeve (47) is partially introduced into the blind hole (1d) and thereby brings about guidance of the shafts (31b, 43) in a manner exactly coaxial to the blind hole axis. <IMAGE>

Title: Arm printer with individual type - has distinguishing character for two text types using additional dual position underline arms
Inventor: HARASKO ERICH DIPL ING
IPC: B41J35/20
Filed: 1979-11-09
Abstract: A device for individual type arm printers characterises the printer output, esp. as input or output data in data processing systems. It enables distinction between the two text types even when printout is copied, unlike the case of dual colour identification systems. An additional type arm (4) can be positioned as required with its striker face (9) in contact with the individual regular type arm (3) so that it prints a marker character, e.g. an underlining, as the regular arm moves forward to print. The additional arm may be slid into position beneath the regular type face from below so as to lie in front of a colour tape (5). The arm is a spring-loaded frame with the distinguishing character at the top.
