Patent DE-2726361-A1 (DE)
Title: Lead recovery from scrap accumulators - by crushing, sieving and sepn. into lead, lead cpds. and plastics
Inventor: TRIEP EUGEN DIPL ING
IPC: H01M10/54
Filed: 1977-06-10
Abstract: The scrap is first crushed, and then sieved to obtain a coarse fraction which is sepd. by flotation to form heavy materials and light materials. The fines obtd. from the sieve are suspended in circulating water and fed through a hydrocyclone to obtain heavy materials and light materials. The sieve pref. produces fines of 0/8 mm, esp. 0/5 and 0/6 mm; and the hydrocyclone pref. has an effective washability adjusted for sepn. at 1.5-1.8, esp. 1.6-1.7 kp/dm3. After leaving the hydrocyclone, the materials pref. pass through dewatering sieves to recover water, part of which goes to a concentrator or evaporator before being re-used to form the aq. suspension fed through the hydrocyclone. About 40% of the world prodn. of Pb is employed in accumulators so the recovery of Pb from scrap accumulators is very important. The invention provides various improvements over previous methods and is cheaper.

Patent DE-2741272-A1 (DE)
Inventor: LUETHY OSKAR
IPC: A61H15/00
Filed: 1977-09-14
Abstract: The roller arrangement for the feet differs from known roller arrangements of this type, having a plurality of massage rollers lying parallel to one another, in that the axis of the roller (R4) situated furthest outside in the direction of the front of the foot can be mounted either in the same plane as that of the other rollers (R1, R2, R3) or else can be raised towards the user side and situated at a distance from the next roller which is greater than the distance between the other rollers, as a result of which an improved massage of the sole, particularly the area between the toes and the sole, is achieved. By additionally providing the massage rollers with copper wires or chains, and as a result of the possibility of wetting the rollers, a further increase in efficacy can be achieved. <IMAGE>

Title: Reciprocating swashplate type hydraulic motor - has axial cylinders in stationary drum surrounding revolving shaft and swashplate
Inventor: DIENER HERBERT
IPC: F01B3/00
Filed: 1977-11-21
Abstract: The motor has an output shaft (15) which carries an inclined swashplate (11) midway along its length. It has a valve plate (17) at its far end. The shaft with the swashplate and valve plate revolves within a stationary drum (2) which is assembled from two axial sections (6, 7). The drum contains opposed axial cylinders (8) on either side of the swashplate. A piston (9) reciprocates in each cylinder and is given its motion by the rotation of the swashplate. The valve plate admits and releases hydraulic liquid to and from the cylinders through passages within the shaft. The construction reduces the rotating masses and thus enables quicker acceleration and deceleration.

Title: Regenerating mixed ion exchange resins for water desalination - by backwashing then removing middle layer of mixed resin
Inventor: YOKOTA KENJI
IPC: B01J49/09
Filed: 1978-01-03
Abstract: Method for regenerating mixed anionic and cationic exchange resin comprises backwashing with water to separate the resin into upper, middle and lower layers. The upper and lower layers are regenerated separately then remixed. The middle layer of mixed resin is withdrawn and added to the resin mixt. during the next regeneration process at same stage before backwashing. Either the upper or lower layer is also removed for regeneration and pref. fine particles are removed from the middle layer. Used for water desalination e.g. in thermal or nuclear power station boiler systems. Since only pure resin layers are regenerated loss of regeneration efficiency and ion-exchange capacity are prevented. Water quality is thus improved esp. the amt. of impurities such as Na+ introduced from any cation exchanger mixed with the anion exchange during regeneration with NaOH.

Title: Fuel gas ignition system - has flame sensor and oscillator circuit extinguishing spark when flame appears
Inventor: YOSHIMATSU TAKESHIRO
IPC: F23Q3/00
Filed: 1978-03-07
Abstract: The gas ignition arrangement has a feeder switch for an oscillator circuit. The oscillator circuit is controlled by a flame sensor. The oscillator output voltage is stepped up by a transformer connected to discharge electrodes. Ignition sparks are generated on closing the feeder switch. The igniter is disconnected automatically when a flame appears, for preventing unnecessary consumption of battery or other source of power. A flame sensor (11) is fitted into the area of gas flame so that the oscillator circuit (3, 4, 5) is switched off when flame appears. The flame sensor circuit is completed with the flame sensor (11) and by the conducting flame. The feeder switch (2) is linked with a fuel outlet arrangement.

Title: Prodn. of cigarette with reinforced end - removing different quantities from tobacco strand portions forming opposite ends to leave thicker filter end
Inventor: RUDSZINAT WILLY
IPC: A24C5/18
Filed: 1978-07-24
Abstract: The system produces cigarettes with reinforced ends, forming an endless strand of tobacco from a stream to which excess tobacco is delivered.

Title: Uniting fabric layers by heat and pressure - by incorporation of weldable yarns in the fabric structure
Inventor: STUPPARDT RUDOLF
IPC: D06M17/00
Filed: 1978-12-29
Abstract: In a process for joining together two textiles, surface to surface, such as a lining material to an outerwear fabric, the fabric is composed at least partially of heat-weldable yarns, which units the two layers of material under the application of heat and pressure. The weldable yarn may be a polyamide or copolyamide with a softening temp. of about 120 degrees C; or it may be of polyethylene or a copolyethylene material with a softening temp. in the range 110 degrees-140 degrees C. It may be a covered yarn; and it may, alternatively, be incorporated as the under-thread of a sewn seam. The process replaces that of distribution over the textiles of adhesive material in the form of powder or film, which may not occur uniformly and create waste material. The composite material produced has a homogeneous, unified structure with improved strength, handle and flexibility. The technique can be employed in various applications where materials comprising two or more layers of fabric are required, with the aim of improving the life, the stability and the usefulness of the material. Common applications are in outerwear; upholstery for domestic furniture or car seats; camping equipment.

Title: Pivoted circuit board tester unit - has angled chute with liftable strips for diverting rejects
Inventor: STROHMEYER LOTHAR
IPC: B07C5/36
Filed: 1979-03-16
Abstract: A simplified tester for printed circuit boards ensures a rapid and reliable checking. It has strips set at an angle to the direction of the incline. The strips are connected to the tester for tilting into one of their two positions depending on the result of test. The checked board reaches the inclined surface through an opening and when it is in the acceptable state the strips do no project over the surface. This allows the board to slide down freely. Short-circuit or broken connection in the board causes a lifting of the strip to divert the board to the corresp. reject box.
