Title: Plastics ladder with integral rungs and stringers - of hollow trough section, esp. of polyester or thermoplastics
Inventor: BONNET CHRISTIAN
IPC: E06C1/06
Filed: 1974-02-01
Abstract: A ladder element comprises side stringers and rungs all formed integrally as one plastics component. Pref. the stringers and rungs are of hollow or trough-like section, so that the ladder element is an open shell. Two such shells may be bonded together, e.g., by gluing, welding, screwing, etc., to form a closed section hollow ladder. For either the open, single-shell type or the closed, double-shell type, the open spaces between adjacent rungs may be stiffened, e.g., by diagonals which permit sufficient space for the toes, or alternatively by fully closed panels which are however offset or recessed from the main plane of the ladder to give th form of a step providing adequate toe hold. The tread region may be roughened or treated with a coating to improve grip. Prefd. matls. include polyester, esp. hand-laid, pressed or injection moulded, and thermoplastics, opt. contg. glass fibre reinforcement. Plastic foam, balsa wood, etc., may also be used. The element is light in weight, corrosion-resistant and esp. easy to mfr. due to the integral construction without joints. The single-shell type is esp. strong.

Title: Automatic door closer for train - has photoelectric system for sensing objects trapped between door panels
Inventor: RAPPENGLUECK WALTER
IPC: E05F15/43
Filed: 1974-07-04
Abstract: The photoelectric device (1) has a light source and sensor arranged above the door, and the light beam is directed on monitoring through one or more flexible covers (4) in the vertical direction in front of the door sealing lip. A reflector (2) is provided within the door flexible covers. The photoelectric system is connected by a limit switch at a point when the door is almost closed. In the case of an object being trapped between sliding doors, the flexible covers are deformed and the light beam is interrupted so that the photoelectric circuit is actuated to monitor this event. This reflector can also be arranged on the door threshold. Alternatively a sensor can be used instead of the reflector.

Title: Luminous scale cct. - consists of several light emitting elements connected in series in same direction
Inventor: SCHIRMER RUDOLF DIPL ING
IPC: G01R13/40
Filed: 1974-09-07
Abstract: Each light emitting element is controlled by a parallel switching transistor.

Title: Automatic stamping and bending machines for mfg small parts - using roller chain and chain wheels to actuate tools
Inventor: KATZ WOLFGANG
IPC: B21F3/00
Filed: 1974-12-03
Abstract: In a driving unit for automatic stamping and bending machines, an endless roller chain is employed to drive the individual bending and stamping tools via chain wheels. The various tools are pref. located on one assembly plate and are independent of a pitch circle, i.e. the tools do not need to be located on a common pitch dia. Both sides of the chain are pref. employed to transmit the power so shock absorption during bending or staming is improved. If required, additional tools can be mounted on the reverse side of the assembly plate, which was possible when a central driving wheel was used in conventional designs. Used for high speed automatic prodn. of shaped springs, leaf-springs, clips, electric contacts, and other small parts. Gives improved flexibility w.r.t. the sequency of mfg. operations which can be undertaken, e.g. the tools do not have to be located round a circle with a common pitch dia.

Title: Battery testing circuit for emergency power supplies - discharges test battery through inverter into mains
Inventor: SPECKMANN WERNER ING GRAD
IPC: H02J9/06
Filed: 1974-12-31
Abstract: The circuit is provided to permit the periodic controlled discharge of batteries to a predetermined minimum voltage in order to make tests of life and storage capacity in accordance with mandatory standards. Each section of a battery group is connected in turn to an auxiliary d.c. busbar and disconnected from the main bars. An inverter connected to this auxiliary bus then discharges the battery section at sensibly constant current into the a.c. mains. By this means the losses arising from the test are minimised, the discharge rate kept constant, and the availability of the remainder of the battery group for emergency power supply duty unimpaired.

Title: Tachometer for aircraft or spacecraft - with precise measurement of effective speed of craft by craft itself used beam of light passed through optically dense medium
Inventor: BROESSKE LUDWIG
IPC: G01P3/36
Filed: 1975-01-07
Abstract: Tachometer for aircraft or spacecraft comprises a moving optically dense medium (M) through which two interference beams (A, B; C, D; D', C', B', A') are passed in opposite directions, which provide direct indications or, when the arrangement is reversed, shifts which are measured by electronic or other sensing means and which can be converted to direct speed values by automatic means on the basis of experimental values. If the assembly moves at a speed of 'v', according to the Fizeau test the beam CD is delayed and the beam D'C' is accelerated, causing an interference shift which doubles on rotation of the apparatus.

Title: Contact mechanism for relay - avoids contact chatter by defining relative positions of spring arm contacts in terms of motion
Inventor: BOSCH WERNER DIPL PHYS
IPC: H01H1/50
Filed: 1975-03-21
Abstract: The contact mechanism, for a relay, has a pair (G22, G21) of contact buttons on the free ends of spring arms, whose opposite ends are wound around fixed posts (S1, S2), and a moving contact button fixed to a moving spring arm (F6) whose opposite end is likewise wound around a fixed post. Lines (M6, M21 etc.) drawn through the centres of the motions of the moving contact arm and the 'fixed' contact arms intersect the point of contact (K2) to form a triangle.

Title: Equipment attaching soles to indoor shoes - leaving felt outer sole visible under plastic border
Inventor: GERISCHER MICHAEL
IPC: A43B1/10
Filed: 1975-04-01
Abstract: The felt outer sole is thought to be more comfortable in wear than the plastic soles hitherto used. At the same time, the invention aims to rationalise the industrial methods now in use. The outer sole, bottom filling and heel wedge are fastened together and placed in a former under the metal-laster upper, which sinks into the former to a depth of 2-3 mm. Plastic, introduced through the opening runs round the sides of the bottom filling and heel wedge, but is kept by the close fit of the former from flowing over the sides of the outer sole. If desired, the plastic can also be used as a substitute bottom filling.
