Title: Recovering lead from spent batteries - by cruching, burning and melting in an oxygen atmosphere, slagging the sulphate, and recovering the residual lead from the waste gases
Inventor: FISCHER REINHARD DR
IPC: C22B7/02
Filed: 1974-04-30
Abstract: The process for recovering Pb from spent acid Pb batteries comprise, after removal of the acid and neutralisation of residual acid, crushing the batteries to a particle size of 5 mm in a unit to which is feed an alkali- or alkaline earth oxide, -hydroxide, or -carbonate, or a mixt. of these. The crushed mixt. is molten in a furnace with an oxygen enriched blow under slightly reducing conditions and under a sulphate slag layer, the molten Pb being tapped. The waste gases, after removal of the greater part of dust, are passed through a furnace of larger cross section, which is also provided with an oxygen blow, and in which the residual Pb is molten. The gases are then cooled in a heat exchanger and passed through a dust precipitator. The process is simple and time saving and does not require magnetic separators and the use of cascade sieves. Environmental pollution problems are avoided.

Title: Self adjusting handbrake linkage for brake cylinder - with self locking link between linkage and piston to even out travel
Inventor: VUYST HUGO DE
IPC: F16D65/54
Filed: 1974-05-09
Abstract: The hydraulic brake piston (2) is fitted with a special mounting containing a stack of flat metal plates (4). The stack of plates is surrounded by a hollow cylinder (5) to which is clipped the yoke end (6) of the handbrake linkage. The cylinder is spring loaded to slide over the stack. When the handbrake linkage is pulled up the yoke tilts and a nose of the yoke presses a pressure peg (11) into the stack to displace some plates. The other end of the plates is displaced through a hole in the other side of the cylinder. The cylinder is thus locked firmly onto the stack, and is released when the handbrake linkage is released.

Title: Telephone instrument with flash key - has cct for delivery of brief interruption of specified duration
Inventor: SILBER MANFRED
IPC: H04M1/53

Title: Multi-position pull switch for electric motor - has axially shiftable switching rod pivotally supporting contact wiper with snap-action spring inbetween
Inventor: ZOEBL HELMUT
IPC: H01H1/54
Filed: 1974-08-30
Abstract: The pull switch for an electric motor in vehicles has off, start and run positions, and a snap-action hemispherical spring (20) linking the contact wiper arm (19) and the axially moving switching rod (14). The spring holds the contact wiper arm in an end position defined by a stop (22), when the switching rod is in an end position. In this end position the wiper arm makes no contact. As the rod moves out of its end position, the contact (19a) at one end of the wiper arm touches its opposing contact (29). As the rod moves farther, the spring snaps the wiper arm over so that the contact (19b) at its other end touches its opposing contact (30), while breaking the first contact.

Title: Preheating or predrying webs - using combined effect of hot air supply and irradiation to ensure uniform temp distribution
Inventor: KLIMEK CAROL MARTIN DIPL ING
IPC: F26B13/10
Filed: 1974-11-04
Abstract: Textile are pre-dried by using a convection effect provided by hot air taken completely or partially from a web treating machine and using simultaneously an irradiation effect by exposing the web directly to 180-200 degrees C. The hot air is supplied to the web uniformly using a distributor provided with Coanda-effect nozzles permitting of direct and indirect air supply to the pre-drier. Air is supplied to the distributor for impinging normally to the web surface through spigots, lateral openings in the side walls of the distributor as well as through parallel rows and staggered rows of openings in the cover of the distributor. The air supplied in this manner after impinging on the web across its whole width is exhausted by natural or induced draught. Used for pre-heating or pre-drying textile web prior to feeding them to heat treating appts. Size of web treating appts. is reduced. Webs are uniformly heated and production rate is increased.

Title: Phase shift of multi-terminal network as frequency function - uses constant frequency reference oscillator and variable frequency test oscillator
Inventor: HIROSE MASAAKI
IPC: G01R27/28
Filed: 1974-11-07
Abstract: The phase shift is used in an analyser of frequency characteristics. The two oscillator frequencies are mixed in a first mixer, whose output voltage is applied to the multi-terminal network. The output voltage from the latter is applied to a second mixer controlled by the test oscillator, and the test frequency component extracted; then the reference frequency phase is compared with that of the reference oscillator. In order to measure the amplitude characteristic, the reference frequency component amplitude is compared with that of the reference oscillator signal. The measuring oscillator may be energised by a periodically variable deflection voltage, changing its frequency accordingly.

Title: Selection device for multichannel monitoring and operation - designed for test value processing from odd number of lines
Inventor: MACHAC VLADIMIR DIPL ING
IPC: G05B9/03
Filed: 1975-01-23
Abstract: The multi-channel lines carry analogue signals of about the same amplitude. The system has a logic circuit for formation of a common output signals smaller than the greatest, and greater than the smallest input signal, or proportional to such a signal. A monitoring circuit responds when an input signal deviates too much from the rest. The logic circuit is a selection type which detects the line with the highest analogue signal as well as the line with the lowest analogue signal. It prevents these lines having an effect on the output signal. The logic circuit output signal depends on the line's input signal to carry the mean value of all analogue signals.

Title: Layered insulated chipboard and plastics flooring panel - with offset grooves and cross stems on both sides of foamed plastic layer
Inventor: MANG JOSEF
IPC: E04F15/10
Filed: 1975-02-27
Abstract: The flooring element is in the form of a chipboard panel, with a continuous panel of foamed plastic glued onto its underside, as used between a concrete or other ceiling and a floor covering, with the foamed plastic providing heat and sound insulation. Here a series of parallel wide groove-shaped recesses (3, 4) is incorporated in the top and bottom bearing surface of the foamed panel (2) leaving cross-stems (5, 6) between them which are narrower. The recesses on one bearing surface are offset relative to those on the other, in such a way that there is always a cross-stem on one side opposite to a recess on the other side. The grooves may be rectangular, trapezoid or round-edged in cross-section. A layer of moisture-checking material may be let into the top surface of the chipboard panel. Deformation of the chipboard panel, resulting from uneven moisture retention, is prevented.
