Patent DE-2714543-A1 (DE)
Title: Continuous feeder for packaging machine - uses two vertically movable conveyors, forming step to delay individual containers
Inventor: FREUDENBERG CLAUS-DIETER
IPC: B65G47/32
Filed: 1977-04-01
Abstract: The feeder is for the continuous supply of similar containers to a packaging machine, esp. using plastics sleeves. The feeder consists of two continuous conveyor belts behind each other. The front belt moves at a higher speed, to produce a distance between individual containers. One of the conveyor belts (1, 3) may be swivelled about an axis, extending parallel to the axis of the rollers (2) supporting the belts. The facing ends of the belts may be moved in a vertical direction between two extreme positions. In one position, the two conveyor belts are on the same level, while in the other position, they form a step, which cannot be overcome by the container (4).

Title: Bob sleigh with leading and trailing steerable runners - has pivot axes inclined opposite to each other to allow seat to tilt
Inventor: MAEGELE JAKOB
IPC: B62B13/08
Filed: 1977-05-10
Abstract: The bob sleigh has two pairs of runners, the rear runners carry the seat and the front runners are joined to the seat by a steering linkage.

Title: Tube for sepn. by centrifugation - is made of synthetic material and contains moving cylindrical separator preventing subsequent remixing
Inventor: BALLIES UWE DR MED
IPC: B01L3/14
Filed: 1977-08-02
Abstract: A tube for the sepn. by centrifuging of the heavier components from the lighter components of a liq. e.g. blood, and preventing subsequent mixing of the components, contains a cylindrical body, the density of which is between that of the components, and the external dia. of which is equal to the internal dia. of the tube. The tube is made of a synthetic material. During the centrifuging, the cylindrical body slides along the tube. The lighter component flows past it in the space formed between the body and the tube by the slight expansion of the tube, so that the body is always at the interface between the heavy and light phases. A suction piston may be attached to the cylindrical body and the tube may have a ferrule for an injection needle so that a sample can be drawn into the tube. The suction piston shaft is removed before centrifuging. Problems associated with excessive friction between glass tubes and plugs of elastomeric material, diffusion of mixt. through filter discs, and complicated methods of introducing the sample are avoided. The appts. is simple to make, e.g. by injection moulding. Mixing or diffusion of dissolved components is prevented, even during transport or prolonged storage. Filling is simpler, partic. when the appts. is used for sampling blood.

Title: Spring loaded brake lever on skateboard - is operated when user steps off board by action of link arm attached to mounting bracket
Inventor: BURGERT JOSEF
IPC: A63C17/01
Filed: 1977-08-10
Abstract: A skate-board(10) is provided with a mounting bracket(11) which is attached to the underside of the board. A horizontal pivot pin at one end of the bracket(11a) locates a lever(15) whose free end is provided with a brake pad(16). When the skate-board carries a person on its top surface, a link arm(13) which is attached to the opposite end of the mounting bracket(12) and the brake lever, pulls the brake pad away from the skate-board rollers(17). If the person steps off the board, a compression spring(14), acting on the link arm(13), extends and applies the brakes(16).

Inventor: MATSUURA RYO
IPC: C07C49/792
Filed: 1977-08-18
Abstract: is heated at >200 degrees C in an atmos. free of oxygen, to prepare anthrone. This process is novel, simple without using large amounts of mineral acid, solvent and expensive catalyst required by conventional methods.

Title: Bandstop filter with two or more quartz crystals - is designed to permit filter to cover several stop bands
Inventor: BUECHERL ERWIN DIPL ING
IPC: H03H9/54
Filed: 1977-08-25
Abstract: The bandstop filter allows two or more quartz crystals(Q1, Q2) to be incorporated thereby permitting the filter to be used for several stop bands. The two crystals are connected into a crossed circuit whose diagonals contain reactances that are roughly the reciprocal of the resistance in the pass-bands. The two or more stop bands are attained by choosing the diagonal reactances such that they have a phase condition that is roughly an odd integral multiple of 90 deg. at the given stop frequencies. Specified resonant circuits are connected in parallel with the longitudinal and/or diagonal reactances.

Title: Filter for oil separation from water - contains filter material in mesh bags for easy replacement
Inventor: DIETZ EKKEHARD
IPC: B01D17/02
Filed: 1978-07-18
Abstract: Oil is separated from impure water by passing it through a bed of filter material to which the residual oil forms a bond. The filter material is filled in mesh bages of a shape to suit the contours of the container. This saves the manual labour of shovelling the filter material out and replacing it by fresh material. This work can now be done by a lifting appliance. Wash-outs of the filter bed surface are also eliminated.

Title: Detachable telescopic pipe connection - has clamp fitted over inclined overlapping joint which allows pipes to be easily separated
Inventor: HEILAND HANS DIPL ING
IPC: F16L21/06
Filed: 1978-12-08
Abstract: Two pipes (1, 2) are joined by sliding one inside the other, with a clamp (3) then fixed around the outside. The ends (1', 2') of the pipes (1, 2) are cut off at an angle, so their edges are parallel to one another. The inner pipe (1) is slid so far into the outer (2) such that the rearmost corner (1") of the inner pipe does not reach the vertical plane passing through the rearmost corner (2") of the outer pipe.
