Title: Lead, copper, zinc and silver recovery from sulphide concentrates - by sequential sulphuric acid, lime and chloride leaching
Inventor: PETERS ERNEST
IPC: C22B3/00
Filed: 1977-11-11
Abstract: Pb, Cu, Zn and Ag are selectively recovered from sulphide concentrates by (a) contacting the concentrate with sulphuric acid in the presence of oxygen at elevated temp. and pressure (pref. >=100 degrees C and 60-80 psi) to extract Cu and Zn values; (b) contacting the concentrate with lime (pref. at 95 degrees C) to remove elemental S; and (c) contacting the concentrate with a mixt. of CaCl2 and FeCl3 to extract Pb and Ag values. The metals are recovered in high yields from low grade materials such as smelter dusts, metal drosses, middling concentrates from flotation, etc. Pyrite gangue in the concentrate remains inert at all stages of the process.

Patent DE-2752593-A1 (DE)
Inventor: BRAENDLI GEROLD DR
IPC: H01J61/30
Filed: 1977-11-25
Abstract: In the case of a low-pressure gas-discharge lamp of high radiation intensity in the region of the 254 nm line, the structural design of the discharge tube (1), which is filled with mercury and noble gas and contains two discharge electrodes (3, 3'), is intended to be simplified and, at the same time, the life and efficiency are intended to be improved, while maintaining a high radiation intensity. This is achieved in that two thermoemissive electrodes (3, 3') are provided which are virtually identical in terms of their geometrical dimensions, their construction and their material composition and to which alternating current can be applied, and in that argon, krypton and/or xenon is provided as the noble gas, at a gas pressure of between 0.01 and 0.5 torr in the operating state of the discharge lamp. This lamp can be used as a high-current, low-pressure UV radiation source for killing germs in the food and packaging industries. <IMAGE>

Title: Tuning aid for car radio - mutes sound output until signal is tuned in with field strength exceeding threshold level
Inventor: SNDLER HANS-JOACHIM
IPC: H03J3/12
Filed: 1977-12-09
Abstract: The tuning aid, for a car radio, allows the driver to distinguish weak from strong stations at the very outset and thereby select a strong station. It is esp. intended for use in the VHF band. A manually operated pulse switch (12) actuates a muting circuit (11) that suppresses sound output. A detector (13) compares the field strength of a station with a given level and disables the muting circuit when this level is reached.

Title: Granulate for oil absorption and degradation - prepd. by drying bacterial sludge from water purificn.
Inventor: ZAHN RICHARD
IPC: C02F11/12
Filed: 1978-01-28
Abstract: Granulate made from bacterial sludge from biological purification of domestic and industrial effluents, by careful drying to retain active bacteria in the pores, is used for absorption of mineral oil and similar pollutants, and subsequent degradation. Used for addn. to conventional granular absorbents after use, treatment of contaminated workshop floors in the metal processing industry, etc. The granulate can be stored for years and rapidly regains its original biological activity when water, biodegradable material and air are added. When dumped after use for oil absorption, the oil is degraded and risk of pollution eliminated. Development of unpleasant smells is prevented by addn. of oxygen-releasing salts, without killing the bacteria.

Title: Flexible packet tying machine - has arms moved to grip packet through spring loaded lost motion connection
Inventor: HANSCOM HARRIS FORSYTHE
IPC: B65B13/18
Filed: 1978-05-29
Abstract: The machine for tying parcels has laterally spaced arms (16), connected by a tie (18). They are mounted on a rotary shaft (17) carried by a support (12). The arms can swing freely towards the side of the support. The packet to be tied is held by the free ends of the arms when in a lowered position. A member (25) moves up and down causing oscillation of a bent lever (21, 22) alongside. The movement of one arm (22) is imparted to lever (19) which is connected to shaft (17) through a spring loaded lost motion connection (28 to 31). Pin (43) causes spring loaded latch (40) to engage so that arms (16) hold down whilst the packet is tied. A rotary cam then releases latch (40) and spring (38) returns the arms and lever upwardly for the next cycle.
Patent DE-2832512-A1 (DE)
Title: IC engine speed limiting circuit - has pulse shaper stage and electronic stage switching path to ignition magneto in parallel to utilise half-waves, unnecessary for ignition
Inventor: WESEMEYER JUERGEN DIPL ING
IPC: F02P9/00
Filed: 1978-07-25
Abstract: The circuit trips switching steps in dependence on the engine speed. The engine ignition transmits speed pulses via a pulse shaper stage (12) to the input of a measuring stage (13) with an electronic switching element. This stage output is in parallel to a capacitor of a series RC element, the capacitor being connected to the input of a gate whose output is in parallel to a capacitor of a second series RC element, coupled to the input of a further gate. The output of this gate controls an electronic switching stage (14) tripping the switching step. The pulse shaper stage and the electronic switching stage path are parallel connected to the terminals of the ignition magneto (17), whose half-waves not required for ignition are supplied to the measuring stage via the pulse shaper stage. The half-waves necessary for ignition are supplies to the electronic switching stage.

Title: Emergency telephone connection construction - uses simple operation on domestic telephone instrument to trip switching process which connects it to required point
IPC: H04M11/04
Filed: 1978-08-29
Abstract: The telephone connections are built up between a point requiring assistance and a point which can provide assistance. A simple operation at the point requiring assistance trips an automatic switching process from at least one wired telephone station. When the connection is established, information can be exchanged between the two stations. The point requiring assistance uses a domestic telephone station. The data for acquisition may include name, place and risk factors for the person requiring assistance.

Title: Portable electromechanical weighing machine - has load plate and strain gauges fitted to bending support beams for indicator mounted on vertical frame
Inventor: PFREUNDT HANS-GUENTHER
IPC: G01G19/12
Filed: 1978-11-02
Abstract: The scale measures the weight of a load placed on the load plate (1). The load plate is fixed to parallel beams (7) by supports (11). Each beam is pinned to the base frame (3) at two points (6) near its ends. Each beam has a circular centre section of reduced cross -section (4). A strain gauge (5) is fixed to the bottom side of the centre section. A load placed on the scales causes the beam ends to move downwards which results in the beam centre moving upwards. This bending is measured by the strain gauge which controls the display unit (10). The frame is supported by wheels (7) and is moved by pushing the handle (8).

Title: Multicylinder reciprocating IC engine - has common servo valve adjusting compression ratio in all cylinders to maintain efficiency
Inventor: KRUEGER HERMANN DR ING
IPC: F02D15/04
Filed: 1978-11-10
Abstract: The engine has a cylinder block with pistons reciprocating in the cylinders. Each cylinder has an auxiliary cylinder above it in which a piston is moved by oil pressure to vary the effective volume of the working space. Oil from a pump reaches the adjusting cylinders through non return valves from a common connection. It leaves the cylinders through non return valves into a common outlet.

Title: Selective isolating circuit breaker system for several loads - has bimetal thermal element in parallel with main switch and controlling switch lock
Inventor: GOEHLE ROLF ING GRAD
IPC: H01H71/10
Filed: 1978-12-18
Abstract: The system has power circuit breakers associated with each load, having a first tripping characteristic. In front of the breakers is slide-connected a main circuit breaker with a second tripping characteristic, which has a thermal bimetal element in parallel. When a short circuit occurs the current is switched by a change-over device at least partly through this thermal element, which controls the position of an intermediate lever such that the latter moves into the path of an armature, moving with the contact lever and into the region of the switch lock. Thus when the armature is operated, the switch lock is released by the armature via the intermediate lever. The change-over device is preferably controlled by the movement of the contact lever. The change-over switching may be carried out on breaking. A PTC current-dependent resistor may be in series with the bimetal element.
