Patent DE-2337501-A1 (DE)
Title: Separation of connected fabric sections - using a thread drawing mandrel to impart automation and speed
Inventor: ROCKMAN MURRAY L
IPC: D04B19/00
Filed: 1973-07-24
Abstract: Prior to separation, the connected fabric blanks are spread flat by a spreading frame which is then advanced by a belt drive system. During the advancement, a draw thread is partially withdrawn and engaged with a rotating mandrel which serves to forcibly withdraw it from the fabric. This partially separates the adjacent fabric sections, leaving only a connecting 'cord' of yarns. This is automatically and rapidly severed using a cutting knife mechanism which includes a pair of cyclically operating fingers. The continuing advancement of the blanks during the above operations tends to widen the gap between the partially severed blanks and so minimises the danger of damage during the cutting operation.

Title: Wheel for high speed rail vehicle - with tyre secured on braked hub by rubber and insulating layers
Inventor: BERG JOSEF DIPL-ING
IPC: F16D65/12
Filed: 1973-08-14
Abstract: The main part of the wheel has brake surfaces on each side backed by a pattern of ribs which form a ventilator system to draw cooling air in near the hub through openings. The ribs are designed to take up radial and transverse forces. The tyre is fitted to the wheel on a stepped section for lateral strength and is spaced from the wheel by prestressed layers of rubber. Heat insulating layers prevent the brake heat from damaging the rubber while a heat conducting layer spreads out any heat generated in the tyre for efficient dispersal. Heat deflectors at the edges of the cooling holes prevent hot air being blown over the tyre.

Title: Distributor for powder, such as fertilizer - has downward-tapering hopper in the bottom of which is a rotating brush over a sieve fixed in grooves
Inventor: KNOEVENAGEL KURT DIPL CHEM DR
IPC: A01C15/02
Filed: 1973-11-12
Abstract: The powdered fertilizer or pesticide in the hopper is ejected by means of a rotating brush in the bottom, narrow end through the sieve fixed into a groove on each side of the hopper base. The brush is coupled directly or by means of gearing, to the axles of the wheels carrying the distributor. The sieve may be made of strips of finely perforated metal, or a fine mesh. Underneath the sieve, a second rotating brush rotates at a higher number of revolutions than the brush above the sieve, by means of a transmission. The underneath brush broadcasts the powder to both the top and bottom surfaces of plants underneath the machine. Side plates reaching almost to the ground prevent the powder from escaping sideways.
Patent DE-2362362-A1 (DE)
Title: Assembly unit telephone PBX - has switching stages equal to permitted number of simultaneous connections
Inventor: BRAUNBECK WERNER
IPC: H04Q3/62
Filed: 1973-12-14
Abstract: When a connection is built-up in the P.B.X., switching points in only one switching stage are operated, and each extension has individually allocated to it switching means recognising the loop state and supplying the operating current. Switching means are allocated to each extension for internal and external connections. They convert loop state signals into commands for pulse transmission and switching through, and recognise the free or engaged state. They are combined in groups with control devices exchanging signals with each other. Their number is equal to that of possible simultaneous connections. Thus extension can be carried out according to need with respect to both number of telephone stations and connection possibilities.

Title: Drive for electrode holder in arc furnace - has control device with safety device against electrode breaking
Inventor: FRANKE NORBERT
IPC: H05B7/152
Filed: 1974-01-24
Abstract: The danger of breaking arises when the electrode is power driven and hits a solid charge; breaking is avoided by limiting the forces generated during such incident. The electrode holder is connected to a travel and/or speed pick-up tachogenerator and a detector is allocated to the control device, which operates a switch when the pickup signals a stop and a I/U quotient falls below a specified value; this switch causes the electrode holder to lift and the detector can operate the switch only when the electrode is stopped during lowering, or alternatively when the electrode current falls below a specified limit when an operating voltage is applied to the electrode.

Title: Garage door automatic actuator with electric motors - is moved and guided simultaneously by activating chain
Inventor: WIEMER HERMANN
IPC: E05F15/681
Filed: 1974-02-01
Abstract: The system may have one or more electric motors which (each) run in alternative directions. The motors drive endless chains which move and guide the door panels. The garage door actuating system is triggered by a receiver and the signal is amplified and transmitted to the switching relay. A chain is connected to the connecting pins of the guide rolls. The door upper edge contacts the pin of the locking and releasing mechanism when the drive motor is started and the door is smoothly opened and moved horizontally under the ceiling until it contacts a limit switch. The driving chains are arranged on both sides of the door panel. This drive has low noise and its compact size makes it unobtrusive in use.
