Patent DE-2454060-A1 (DE)
Title: Nonlinear braking system for escalators - has brake pads swinging through arc as force is applied to vary braking torque minimising initial braking
Inventor: FORSTMEIER GUIDO
IPC: F16D55/224
Filed: 1974-11-14
Abstract: A disc breaking system for moving staircase escalators has a shaped characteristic such that deceleration is gradual at first and increases towards the end of the cycle. The brake pads (7) are mounted on an arm (6) tied to a support (5) pivotted on a main bearing block (3). The support is cranked (8) to provide a coupling (10) to a hydraulic damper (9). When activated the braking pads contact the surface of the disc (2) coupled to the main shaft (1) of the escalator. The friction force between pads and disc results in the pads moving in an arc about the bearing block centre (3) until a point of equilibrium is attained. The resulting braking characteristic ensures that a sharp initial checking action is avoided and the total braking time is reduced compared with a linear braking characteristic.

Title: Tool for removing protective coating from pipe fittings - is used with electric hand drill for heating installations and consists of wire brush suitable for cleaning inside pipe
Inventor: ROSENKRANZ SIEGFRIED
IPC: A46B13/00
Filed: 1975-01-23
Abstract: The tool (1) has a shank (2) provided at one end with a ball bearing (33), the outer race of which carries a plastics boss (31) with a conical end surface. A wire brush (7) is clamped against the shoulder (29) by the locknuts (26, 27). The other end of the shank (21) is suitable for fitting in the chuck of an electric drill. When the tool is placed over the threaded hole (51) of the radiator (5) the rotation of the wire brush removes the coating used to protect the radiator during transit. The use of the rotating brush prevents damage to the thread (51) but provides a clean surface (53) to ensure a leak-tight joint with the pipe fitting.

Title: Polymeric positive image prodn. using aromatic nitroso dimer - as inhibitor precursor, increasing max. wavelength for selective exposure
Inventor: NEBE WILLIAM JOHN
IPC: G03F7/027
Filed: 1975-09-22
Abstract: An aromatic nitroso dimer (I) is used in the prodn. of polymeric positive images on substrates by coating the substrate with a photopolymerisable compsn. contg. a non-gaseous ethylenically unsatd. cpd. (II), which can be polymerised by free radical-initiated chain propagation, a photodissociable nitroso cpd.

Title: Sequential remote variable measurement and data transmission - produces reliable direct digital output at local transmission line receiver
Inventor: DUELL PETER G DIPL ING DR
IPC: G08C19/22
Filed: 1976-10-09
Abstract: The reliable method is for measuring a variable at the remote end of a transmission line and transmitting the resultant information to a receiving unit at the local end of the line, using a sequential switching technique which produces a direct digital output. The network, consists of a timing and receiving unit (1) and a transmitting unit (3) at the remote end of a transmission line, the transmitting unit (4) being attached to a transducer of some kind. The timer and receiver (1) contains a flip flop and current generator (5) which produce a timing pulse when a reading is required and feed this to the transmission line (2). The transmitter unit receives this pulse and short circuits the line after a time the duration of which is dependent on the amplitude of the variable measured. Meanwhile the receiver allows an oscillator (34) of fixed frequency to increment a counter (35) which proceeds until the line is short circuited by the transmitter. The counter then holds a digital representation of the variable amplitude. Two monostable multivibrators (31, 32) of different pulse lengths a flip flop (4) and an oscillator are used in the timer receiver unit (1) to control this sequence.

The tips of the resetting cores of the digit drums can also form a switching tooth for stepping on the next digit drum.
