Patent DE-2335874-A1 (DE)
Title: Roller conveyor points for link up with branch line - has adjustable points rollers driven by friction element
Inventor: STUMPF KARL
IPC: B65G13/07
Filed: 1973-07-14
Abstract: At the point section of a conveyor a number of horizontal cylindrical rollers are carried by individual forks. A common base locates the spigot end of the forks so that the alignment of the roller axes in a horizontal plane can be altered simultaneously. Thus the rollers remain parallel to one another but any object carried leaves the conveyor at the angle which is formed between the point rollers and the fixed conveyor rollers. Each point roller is driven by a friction roller or a friction belt. They are carried by a common channel section placed inside the forks which carry the rollers. The friction rollers whose rotational planes remain parallel with the conveyor path are spring loaded so that they stay in contact with the circumference of the point rollers.

Title: Flow regulating valve with poppet valve - uses output flow relief pressure tapping for constant flow operation
Inventor: JESCHKE NORBERT DIPL ING DR IN
IPC: G05D7/01

Title: Box garage adjustable in size - has lift taking cars to floor where air compressor switches motor on to park car
Inventor: MILENKO BOSKOVIC
IPC: E04H6/20
Filed: 1974-01-02
Abstract: Box garage whose construction provides 40% more parking area is constructed in situ and can be adjusted in height and length to suit requirements.

Title: Working time recorder - with times recorded on card and automatically counted for central data processing
Inventor: STEIDLE GERHARD
IPC: G07C1/08
Filed: 1974-02-15
Abstract: The time recording system, permits the recording of the times taken in specific activities on a printed card, and evaluation of the data recorded either by inspection of the card or in a central data processor. The card is divided into columns, each for a separate time cycle, and is fed by a motor into the recorder and a marker on the card initiates the action of a path counter for the machine distance travelled by the card. The distance travelled is proportional to time, and starting and finishing times for an operaton are printed at the appropriate parts of a column on the card. The card shifts to present the next column for timing of the next operation. Total times are summed by a timing counter or can be added by inspection of the card on completion of the recording.

Title: Fan light operating linkage - has ratchet wheel rotated unidirectionally by string over pulleys
Inventor: GEBHARD OSKAR
IPC: F24F13/14
Filed: 1974-02-22
Abstract: A bracket near a high level window flap supports a shaft on which is fixed a ratchet wheel. A lever pivoted on the shaft is connected by a spring to a dog pivoted on the bracket. Another spring loaded dog is pivoted on the lever. A string attached to the end of the lever runs over pulleys to a convenient operating position. Deflection of the lever by the string releases the first dog and causes the second to push the ratchet wheel and shaft round. The shaft carries another wheel which is the first arm of a four bar chain linkage such that when the wheel performs a complete revolution the flap reciprocates from open to shut and back again.

Title: Dispenser for measured liquid soap - comprises lever mechanism for opening and closing supply of soap container refills
Inventor: VAHL JOACHIM
IPC: A47K5/122
Filed: 1975-03-06
Abstract: A resiliently compressible container (17) is enclosed in a rigid casing and with an integral delivery opening. A mechanism opens the supply opening when pressure is exerted on the container and closes the opening when the pressure is relinquished. The container is bubble-shaped with a downwardly aligned opening in the form of a tube, opening into the aperture at the bottom of the casing. The operating mechanism comprises a manually operated leverl (16) by which pressure is applied to the container. The lever moves a slide (20), which as pressure is applied to the container via a further lever (23) releases the opening of the hose but on release of the pressure compresses the tube opening, allowing a measured supply of the contents to be dispensed. The supply containers are in the form of throw-away refill packs.
