Title: Extending step for mounting tram - has safety switch operated by lever below step to prevent retraction while occupied
Inventor: KRAMER ROLF DIPL ING
IPC: B61D23/02
Filed: 1975-12-10
Abstract: Access to and from the tram is improved by an extending step (1) which swings out of the profile of the tram under the level of the lowest fixed step (8). The step is supported on two sets of pivoted levers (3,4) which hold it in a horizontal, extended setting. It folds away into a slightly inclined setting under the fixed step when the tram moves off. The step is linked to a safety lever (9) which operates a safety switch (11) and inhibits the retraction movement if the step is occupied. The retraction is reversed if the switch is operated with the step partly retracted. The step reduces injury risk and is simple to operate and install.

Title: Digital PCM signal transmission system - uses pseudo:ternary transmission along coaxial cable with spaced repeaters along line
Inventor: JUNGMEISTER HANS DR ING
IPC: H04L25/24
Filed: 1976-05-25
Abstract: Distance supplies repeaters positioned at intervals along the line comprises an equalising amplifier (VR), an amplitude dicision unit (AE) with two decision thresholds and a certain hysteresis, a clock pulse controlled scanning circuit (A) carrying out timing regerneration, and a clock pulse generator deriving the timing cycle from the signal. In order to produce a separate supply current path at each repeater, a short-circuited line is provided at the repeater input and output, with the output line also serving for reconverslion of the regenerated binary signal into its pseudo-ternary form. A binary- re-coder (UC) is connected in the sending terminal station in series with the circuit converting the original binary signal (sig) into a psuedo-ternary signal. It changes the binary signal at its output when a binary "one" appears at its input. A decoder (DE) is provided at the receiving terminal station (E) which eliminates the above coding.

Title: Signal suppression system for record player - has stereo playback head for generating pair of correlated signals which attenuate source signal
Inventor: SACKS JACK
IPC: G11B3/00
Filed: 1976-12-01
Abstract: The signal suppression system for a record player is used to detect parasitic signals, caused by mechanical defects in the record, which produce cracking. A pair of correlated signals are generated using the source signal recorded on the record. These correlated signals are combined so as to attenuate the source signal and to amplify the parasitic signals for detection of the latter. The two correlated signals may be obtained via a stereo playback head providing two output signals corresponding to two distinct recording tracks.

Title: Baking ceramic blanks which contain fuel - in tunnel kiln designed for max. use of thermal energy in blanks
Inventor: RIEGER WALTER ING
IPC: F27B9/36
Filed: 1977-02-22
Abstract: The blanks travel in the same direction through a preheating zone as preheated air, and then move through a calcining zone followed by a cooling zone which employs a counter-current of cold air. The flue gases obtd. in calcining travel in counter-current to air (1) and form a recuperator heating air (1) before it reaches the blanks, which are heated to their ignition temp. when they reach the end of the preheating zone. In the pref. tunnel kiln, the preheating zone is fitted with two roof arches forming a channel through which gases flow to the recuperator; and air (2) heated in the cooling zone can enter the preheating zone at several points. Fresh air can also be fed into the preheating zone. Used in the mining of coal, mixts. of clay and coal are obtd. which can be moulded into high quality prods., e.g. bricks possessing high strength, plus porosity, which contain sufficient coal so they can be burned in a tunnel kiln without using any other fuel in many cases. Max. exploitation of the heat content in the bricks is obtd. without environmental pollution; The kiln has burners for use when the blanks only have a low fuel content.

Title: Internal combustion engine exhaust system and silencer - uses tubes with multiple bores to cool exhaust gas
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/18
Filed: 1977-05-02
Abstract: A silencer forming part of the exhaust system of an internal combustion engine consists of two concentric tubes (51, 52). These tubes are joined by radial walls (55) which extend longitudinally so that the annular space between the tubes is divided into a number of separate compartments (5). A cooling fluid flows in these compartments (5) in the opposite direction to the flow of gas in the central bore (50). The outer wall of the outer tube (52) has a number of radial fins (56) which also extend longitudinally. These fins help to dissipate the heat which has been transferred to the cooling medium by convection and radiation.

Title: Vehicle fuel economy meter - is incorporated in conventional speedometer and tachometer so that pointers coincide at optimum working rate
Inventor: BUSCH GUENTER
IPC: G01F9/02
Filed: 1977-05-12
Abstract: The fuel economy meter is based on conventional forms of continuous-reading fuel consumption instruments without requiring the attention of the driver which has also to be directed towards the speedometer and/or tachometer. The new meter has a pointer which is incorporated in a conventional speedometer or tachometer instrument. The transmission arrangement between the transducer and the actual display pointer is such that the most economical rate of fuel consumption at the corresponding speed and engine revolutions is shown when this additional pointer is masked by the speedometer or revolution counter needle, ie. the driver endeavours to keep the pointers coincident.

Title: Ultrasonic testing of construction materials - employs pulsed ultrasonic waves to measure propagation time through material
Inventor: YAMSCHIKOV VALERY SERGEEVITSCH
IPC: G01N29/07
Filed: 1977-06-14
Abstract: Building materials such as concrete and granite are tested for faults and fissures by subjecting them to pulsed ultrasonic waves to measure propagation time through the material. A pilot generator (1) is connected to a pulse generator (3) whose output drives an electroacoustic convertor transmitter (7) mounted on the surface of the construction material (8) under investigation. An electroacoustic receiver (9) with two resonators receives the transmitted signals. One resonator receives a direct signal while the other has an inbuilt delay. Both signals are amplified (12, 13) and multiplied (14). The signals are then formed into digital signals having time intervals. After processing the digital signals are converted into video signals.
