Title: Centrifuge with solid bowl - for drying solids with continuous solids removal
Inventor: PECK WILLIAM HOWARD
IPC: B04B11/02
Filed: 1974-06-20
Abstract: A centrifuge has a dish shaped bowl which has sides which slope upwards and end in an open, circular rim. There is a circular flat disc mounted in the bowl and some distance from its surface, forming an annulus. A second disc is mounted above the first forming a second and narrower annulus. This checks the upward flow of slids. The bowl and discs are rotated at high speed as a unit about the vertical axis of the bowl. The solids of the feed slurry which is introduced on the lower disc are thrown outwards in the space between the discs and block the annulus between the top disc and the bowl. The liquid is forced through the lower annulus. A number of ploughs move around the circumference of the bowl and loosen the solids so that they move through the top annulus. Small containers pick up the solids above the top annulus and carry pieces towards the axis. They are lifted above the level of the top of the bowl and are then thrown clear of it. The liquid leaves through an outlet in the bottom of the bowl. Appts. is used for drying powdered coal, sand etc.

Title: Tyre with cross ply tread reinforcement - has reinforced layers prestretched before moulding to final dia.
Inventor: PAKUR HENRYK
IPC: B29D30/00
Filed: 1974-06-25
Abstract: Banded tyres, esp. pneumatic tyres, in which the tread bend comprises reinforcement in two oblique directions (cross-ply), are mfd. by laying the band or individual constituent layers of the band onto the carcass; and, before the band is laid onto the carcass, stretching to increase its dia. by an amt. considerably exceeding, esp. by 5-25(10-20)%, the dia. increase required in the final moulding of the tyre in the vulcanising mould. Pref., the external tread layer is not bonded to the reinforced band until this increase in dia. has taken place. By prestretching in this way, non-uniformity in th reinforced band is balanced out before the band is applied to the tyre, resulting in considerably improved uniformity in the tyre itself, esp. in regard to the direction of the reinforcement.

Title: Thread gripper drive for chain stitch sewing machine - ensuring faultless work at seven thousand stitches per minute
Inventor: LIENEMANN ERNST DIPL ING
IPC: D05B57/32
Filed: 1974-11-12
Abstract: In a chain stitch sewing machine, the motions of the gripper for catching and casting off the thread loop and evading the needle, are effected by a plunger which transmits the movement of a crank on the main shaft, through a tee coupling to the pivot shaft of the gripper arm. Towards its free end, the plunger is machined spherically internally and externally. The outer sphere slides in a guide cylinder having a cutout for a connecting shaft, whilst the inner spheres, offset to the outer, forms a bearing for a ball bored for the shaft. Few components are used so that the very high stitching speed can be achieved cheaply. Noise is reduced and efficient lubrication ensured.

Title: Quadrature phase generator with chain of stages - each consisting of two operational amplifiers giving zero and one eighty degree phase shifts
Inventor: WIECKERT RAINER
IPC: H03B1/00
Filed: 1975-01-09
Abstract: The quadrature phase generator has a phase shifter with operational amplifiers forming a chain. Each stage is constructed from two operational amplifiers one of which performs a phase shift of 0 deg. and the other a phase shift of 180 deg.. the outputs of both these amplifiers are filtered. All circuit elements and amplifiers which can be integrated are grouped into an integrated circuit. The filters can be offset with respect to one another to achieve arbitrary phase shifts. The quadrature generator can also be used as a voltage frequency converter by applying the input voltage to a given point.

Title: Digital fluid control system - has fluid inlet at high pressure and fluid outlet at lower second pressure with several flow channels
Inventor: FRIEDLAND HARRY
IPC: F16K1/54
Filed: 1975-01-09

Each flow channel has an individually actuated valve element with a biconical nozzle, a bistable sealing memer and a positioning device for the sealing member which positions the latter only in a fully open or fully closed position. The minimum difference between the first and lower second pressure is sufficient to make the pressure in the neck of the nozzle independent of the second pressure.

Title: Cutting shapes from glass sheet - through- crack developed by pressure from pneumatically-loaded ball in vertical guides
Inventor: KABANOW NIKOLAJ P
IPC: C03B33/10
Filed: 1975-01-31
Abstract: Shapes are cut out of glass sheet by an appts. including a sheet-supporting table mounted on a frame on which are also mounted a template, a cutting head movable along for making a scratch, and a device synchronised with the head for converting the scratch into a through crack by pressure. The device comprises a tubular guideway in which moves a ball which is urged against the glass surface by fluid pressure. Pref. the pressure device is mounted on a carriage somewhat behind the cutting head, the two components being mounted on a common endless chain. The pressure-applying device can follow the cutting head move accurately than could the previously used roller, while the pneumatic system accommodates irregularities in the sheet surface. Independent mounting of the cutting and pressure heads prevents crack formation advancing ahead of the scratch, and also eliminates oscillation of the cutting head.

Title: Actuator motor for dampers - or flap valves on boilers having gear output with several ratios uses swinging idler gear connecting with wheels of different sizes
Inventor: BUCH ER HERMANN
IPC: F16H3/36
Filed: 1975-03-17
Abstract: The application is principally to the operation of dampers or flap valves controlling the air supply to burners in boilers or heaters. The opening, or closing, time of the damper is determined by the motor speed and gear ratio. In order that several operating times may be available from one motor unit the sprocket (1) on the motor drives the output shaft to the damper through an intermediate gear with several steps (2.1, 2.2, 2.3, 2.4). In a development of this design an idler gear with two wheels (4, 5) on a common shaft is arranged on a swinging link so that the gear (10) on the output shaft can be connected with any of the intermediate steps (2,1......2.4).

Title: Insulated floating floor sub-structure prefabricated element - has monolithic top pressure distributing and second mineral bonded panel layers
Inventor: SIMON WALTER ING GRAD
IPC: E04F15/02
Filed: 1975-04-28
Abstract: The prefabricated structural element is for use in a floating floor sub-structure with sound and heat-insulating qualities, as used in connection with smooth flooring in residential buildings. It is in multilayered form. The pressure distribution and sound and heat insulation are integrated in at least three layers (1, 2, 3), which are sited together in an elastic-plastic combination, and which are conveniently dimensioned to facilitate a rational laying process. The top layer (1) is formed into a monolithic flat pressure-distributing layer in the laying process, both this and the second layer (2) being made of mineral-bonded fibre-reinforced panels, or similar. Together with the bottom layer (3), of thin insulating material, these form a floating substructure of high insulating capacity, with no annoying resonant effect, and usable immediately after laying.
