Title: Meat salting machine - with gear type pump having gear wheels made of plastic material e.g. polyamide
Inventor: BACHERT ARTHUR
IPC: A23B4/02
Filed: 1976-09-23
Abstract: Machine includes a pump which feeds the brine to a hollow injection needle. The pump is a gear-type design and both the gear wheel on the drive shaft and the matching gear wheel which is running freely on the counter shaft are made of plastic material. The gear pump permits a high pressure (6 bar) to be used, thus shortening the injection time. The use of plastics reduces the wear rate so that a long service life is ensured. The gear wheels are easy to replace.

Title: Dough kneading machine - with kneading tool and drive cover tiltable around horizontal axis through centre of gravity
IPC: B01F7/16
Filed: 1976-11-05
Abstract: A dough kneading machine with a kneading trough, pref. drawout type, has a horizontal shaft around which the upper part with the drive and the kneading tool can be swung open.

Title: Cement calcining plant - in which aq. raw material slurry is dewatered, pelletised, and fed through calciner to sintering furnace
Inventor: GOTTLIEB STEVEN
IPC: C04B7/40
Filed: 1976-12-29
Abstract: Parent Patent describes the calcining and sintering of pellets, in which the pellets flow downwards as a bed through a vertical calciner contg. an axial burner providing a descending stream of combustion gases; and the calcined pellets then flow into a rotary drum furnace from which exhaust gases provide additional heat in the calciner. In this Addn., the slurry made from water and raw material flour is partly dewatered to form cake, which is pelletised and fed to the calciner. Coal-dust or -slurry may be added to the raw material, and dust may be added during pelletizing to increase pellet strength. The pref. plant includes presses using a vacuum to remove excess water from the slurry, and a screw feeder driving the cakes to a pelletizing dish. Used for mfr. of cement clinker. Partial removal of the water reduces fuel consumption in the furnaces.

Title: Pocket camera with integral flash - has close-up mode using modulating gray filter to scatter light and supplementary lens
Inventor: ORT WOLFGANG DIPL ING
IPC: G03B15/05
Filed: 1977-01-15
Abstract: The compact camera has a retractable electronic flash unit (2) with a switch (9) which couples the flash to the power supply when pulled out. When the flash is to be used for close subjects it is slid into the camera housing under a gray filter (8) to scatter and reduce the light output, and is coupled to the shutter release by a close-up selector switch (7). The latter (7) also moves a close-up lens (7a) in front of the standard lens. The gray filter can be wedge-shaped to aid the light scattering and to avoid the 'red eye' effect. When closed up the electronic flash is inhibited unless the close-up mode is set.

Title: Frost damage preventing drainage device - has funnelled plate with central hole, and flexible pipe inside rigid pipe
Inventor: THEWES OTTO
IPC: E04B1/70
Filed: 1977-01-29
Abstract: The device is designed to provide drainage for a building, which is free from frost damage, usually caused by shrinkage of mortar in cutouts prepared for posts or other additions. A funnel-shaped plate, of any suitable plan form, has a peripheral upward slope, and a central opening with peripheral downward slope as the drip edge. This leads to a flexible star-shaped folded inside pipe, sheathed by a rigid outside pipe at an interval. The plate and inside and outside pipes are firmly joined together. Collected water runs down onto the funnelled plate, and collected in edge drops which fall downwards through the inside pipe, which has room to expand in the event of ice formation.

The grip elements are made from light alloy castings and are secured by screws (6) and clamping strips (8) on the inside of the castings. The clamping strips have a series of captive nuts and are slid into the hollow section of the grip casting. They enable the light metal grips to be used, rather than steel pressings, to provide a lightweight track, with the grip elements easily replaced when worn.
Patent DE-2717438-A1 (DE)
Title: Moulding tool coating system - sprays lubricant onto working surfaces intermittently and briefly before each compression operation
Inventor: VOSS GUNTER M
IPC: B30B11/00
Filed: 1977-04-20
Abstract: The system sprays a coating of lubricant in solution, fusion or suspension onto dies and punches used in the manufacture of moulded items. Before each compression operation, the lubricant is deposited on the working outer surfaces of the tools by means of nozzles working briefly and intermittently. The nozzles can spray a single substance, or use compressed air, steam or gas as an entraining medium for the lubricant. As alternatives, deposition can be effected by an ultrasonic oscillator, or a continuous jet can be divided into successive ones by a perforated disc driven by a synchronous motor.

Title: Worm drive arrangement for electromechanical load handling appts. - has at least one worm shaft with ball runners converting shaft rotation into reciprocal motion of telescopic arm
Inventor: BETZING VOLKER
IPC: B25J9/04
Filed: 1977-09-20
Abstract: Electromech. load handling mechanism has a telescopic arm (4) within which one or more worm drives are located and driven from brakable electric motor (80). At least one worm shaft has ball runners which convert the rotation of the shaft into a reciprocal motion of the telescopic arm (11). Lateral motion of a swingable port (6) of a horizontal support arm is also derived from the same, or other worm drive. The reciprocal telescopic arm (11) is non-rotatable with the fixed part (4) and the application of the drive motion to this is cushiond by spring pockets in both directions. The construction reduces the physical size of all load bearing parts.

Title: Sugar beet scalding vat - with mash zone covered by degassing screen and gas extraction cowl
Inventor: STRAUBE ELMAR
IPC: C13B10/08
Filed: 1977-11-14
Abstract: A scalding vat to transform shredded sugar beet into a state of plasmolysis is a horizontal vessel with a stepped shaft. The mash zone extends over the length of the smaller-diameter shaft and over 1/4 to 1/3 of the vat length. The upper 135 degrees sector of the mash zone periphery is designed as a screen and is surrounded by a gas collector cowl with a gas extraction pipe. This prevents the froth formed in the vat and the gases released during the plasmolysis from entering the diffusion tower.
