Title: Padded side panel for bus seat - to limit gangway width and secured by conical wedge in concentric tube sections
Inventor: BERMANSEDER ROBERT
IPC: B60N2/24
Filed: 1975-05-16
Abstract: The sides of the seats nearest the central gangway in the bus are fitted with detachable panels which restrict the gangway width to prevent too many standing passengers. The padded panel (1) is mounted on two tubular sections (9) which are slotted axially at the free ends and which slide into larger tubes (10) in the sides of the seat frame. The inside of each inner tube is provided with a conical wedge (8) on a spindle (11) which is tightened by a nut (13) accessible from a cut-out in the padded panel. The panel is thus secured on the side of the seat using simple tools and can be removed by the bus operator when required.

Title: Clothes dryer reverse drive - has drive wheels and freewheel units acting with a common drive belt
Inventor: ROTTMANN FRANZ DIPL ING
IPC: F16H7/08
Filed: 1975-08-28
Abstract: The reverse gear, in the transmission train to a clothes drier or a combined washing machine/dryer compises a drive belt and two drive wheels located between the drive motor and the reverse gear. In conjunction with a freewheel unit, the selection of the appropriate wheel determines the direction of rotation of the fan blade shaft either through one directly-coupled freewheel or a drive from the other freewheel. The assembly and dismantling of the drive unit is simplified as there is only one bearing for the belt drive wheel and wheels with a common tooth formation can be used for both drive wheels meshing into a profiled drive belt.

Title: Hygienic swimming pool water intake system - has part of inflow horizontally directed across bottom to move impurities
Inventor: STAUSBERG HANS
IPC: E04H4/12
Filed: 1975-09-29
Abstract: A water feed system for swimming pools, where high hygienic standards are essential, is used where the water is brought in by the displacement principle. Part, at least, of the volume of water to be introduced, near the pool bottom, is ducted in horizontally above the bottom. The inlet apertures are preferably evenly distributed on the bottom surface, with a larger volume entering horizontally and a smaller one vertically. In addition to the overflow (9) at one end of the pool (1), near the bottom, there can be one or more draw-off outlets (7) for water, while one or more horizontally aligned inlet apertures (5) are fitted at the opposite end, also near the bottom. Sedimentation of coarse impurities is prevented by the current of water flowing across the bottom of the pool.

Title: Adding inoculants and/or alloying agents to metal before casting - where agents are located in pouring funnel used to fill mould
Inventor: VITT GERHARD
IPC: B22D1/00
Filed: 1976-02-28
Abstract: Molten metals are inoculated and/or alloyed by the addn. of agents during the mfr. of castings, the agents being added via the pouring funnel forming part of the mould. The agent(s) can be located in the funnel by coating a sieve plate with the agent(s); making a sieve plate from the agent(s); or placing a disc made of the agent(s) on top of the sieve plate. The agent(s) may also be used as a coating on the pouring funnel, or as a moulding forming part of the funnel. A further alternative is to use a disc made of the agent(s) and located in the funnel below a disc made of plastic or metal which retards the reaction of the agents with the melt. The pouring funnel may also be provided with a plastic sheath leaving a conical annulus filled with powdered agent(s), the plastic sheath being destroyed by the molten metal. Ensures that all the agents react with and are mixed with the molten metal, without the loss of agents which occurs when they are added to a ladle.

Title: Converting industrial dust into pellets - for use as coarse aggregate in concrete mfr.
Inventor: SALOMON DIETER
IPC: C04B18/02
Filed: 1976-07-07
Abstract: Factories remove dust from contaminated air by filtration before the air can be released into the environment. The dust cannot be deposited in the open air because winds would blow it into the environment. The dust is therefore pelletised, and the pellets employed as large-grained gravel in concrete. The use of the pellets recudes the consumption of conventional materials in concrete mfr.

Title: Echo suppressor using artificial telephone echo - has coefficient of intermediate switching circuit reduced when input signal exceeds threshold for preset time
Inventor: SATO AKIRA
IPC: H04M9/08
Filed: 1976-11-05
Abstract: The echo suppressor derives an artificial echo from an echo path pulse response and subtracts it from the real echo, leaving a small residual echo. The pulse response is corrected using the product of the residual echo and the received signal. The suppressor has a switching circuit with variable coefficients (6) between a switching circuit (5) forming the product and a circuit (2-4) for the pulse response correction. Control devices (7, 8) reduce the switching circuit coefficient when the input signal received exceeds a certain threshold value, for longer than a certain time after the end of connection build-up.

Patent DE-2702219-A1 (DE)
IPC: B65G1/08
Filed: 1977-01-20
Abstract: The individual articles (5) are raised in series from below so that they are accepted in a stacking shaft (6) in a plurality of rows (7) of single articles, located one above the other. These rows (7) of single articles located one above the other each form a column and are supported during the stacking process by retaining elements arranged in the stacking shaft (6) and released from the retaining elements during the unstacking process. In order to permit extensive buffer possibilities with high throughputs, the first column of individual articles is moved transversely for the purpose of storing after reaching a height that can be predetermined, and together with the stacking shaft (6) surrounding it. The second column and further columns thus formed are likewise moved transversely together with the stacking shaft (6) that then surrounds them. The process intended for unstoring the articles then proceeds in reverse sequence. <IMAGE>

Title: Photoelectric receiver signal transformation - provides binary signal dependent on output signal by using variable or fixed reference
Inventor: KUGLER ROLAND
IPC: G06K7/10
Filed: 1977-03-25
Abstract: A system to transform the photo electric receiver output signals received when checking marks on a drawing carrier into a binary value (25) by comparing the signal with a reference value. The reference value (41, 43, 44) is changed proportional to the signal amplitude (26). An alternative is that the output signal is delayed by limiting the signal in the region of a constant reference and releasing it when the amplitude is exceeded. The input signal is passed via a capacitor and a clamping circuit to prevent polarity change to one input of a comparator. The other comparator input is connected to the reference value. The signal (26) switches an integrator when larger than the reference value and so changes the input signal to the comparator. Further suitable circuits are described.
