Title: Pneumatic system pressure intensifier - has valve for variable input pressure in bore of control body
Inventor: ROTH GUENTHER
IPC: F15C3/04
Filed: 1974-10-10
Abstract: The intensifier has a bored control body which may be displaced within housing. Both bodies form a first valve, to control the air outlet into the atmosphere. A second valve (15, 16) is formed between the housing and the bored body, to control the air supply to one outlet, and a variable input pressure, acting onto the other body. The air supply (Z) is guided between the valve seat (16) and a membrane suspension (14) of the bored body. The active membrane surface and the valve seat have the same diameter. The output pressure (A) engages in both directions on the bored body via two surfaces of the same size. The piston body (5) is suspended from two membranes (7, 8) of different diameters.

Title: Sugar cane shredder construction - with multi blade cutter sliding over perforated disc and suction pump impeller
Inventor: PRESS VIKTOR ING GRAD
IPC: B02C18/12
Filed: 1975-04-17
Abstract: A shredder for fibrous matl., such as sugar cane, which has to be shredded for the rapid sugar analysis of a sample, consists of a multi blade cutter which is revolved by a motor as it slides above a perforated disc. The impeller of a suction pump arranged below this disc acts as the conveyor for the carrier liq. in a container with the sugar cane. This saves time of up to over 50% compared with the conventional beater blades. The temp. rise is much less and does not affect the result of the analysis.

Patent DE-2537220-A1 (DE)
Inventor: BOTTLAENDER WILFRIED DR ING
IPC: F24F8/133
Filed: 1975-08-21
Abstract: The space requirement and spraying water required and the resistance to flow of the air passed through are intended to be lower than in a spray chamber air scrubber. The open cross-section of a rectangular air duct section is covered by a thin filter sheet (1) made of tangled fibre web having a density of packing increasing in the air flow direction and inclined to the air flow direction. Upstream of the air intake side (6) are arranged spray jets (7, 14) which moisten the filter sheet (1) by spraying water (8). By increasing inclination of the filter sheet (1) to the vertical, the residence time of the moistening water in the filter sheet (1) is increased. In channels (10, 16) or bottom troughs (27), the water leaving the filter sheet (1) is collected; it can be sprayed again as water (8) from the spray jets (7, 14). By intermittent spraying, the required amount of water (8) to be sprayed is reduced; by occasional drying, algal and bacterial infestation of the filter sheet (1) is significantly restricted. <IMAGE>

Title: Asymmetrical controlled rectifier with high power factor - has forced commutation on two phases of three-phase bridge comprising thyristors
Inventor: FOERSTER JOHANNES PROF DR ING
IPC: H02M7/162
Filed: 1976-10-01
Abstract: The three phase bridge rectifier feeding a dc load (1, 2) has thyristors in four arms (5-8) and diodes (3, 4) in the remaining arms. The thyristors are provided with forced commutation circuits comprising auxiliary thyristors (19-21) commutating capacitors (9-12) and their charging circuits (17, 18, 13-16). Control is by triggering the main thyristors at the voltage crossover point and then commutating them off to give the required output voltage. The combination of controlled and uncontrolled elements in the bridge combined with forced commutation and capacitors larger than necessary for commutation only enables the rectifier to operate with nearly unity power factor and low harmony distortion.

Title: Transformer lamination insertion apparatus - has actuator with adjusting wedge to control height of bundle inserted into winding former
Inventor: LEICHER HANS
IPC: H01F41/02
Filed: 1976-12-15
Abstract: An automatic assembly machine for insertion of bundles of laminations in the winding former of small transformers includes an actuator to move the bundle of laminations and a height equalising wedge to ensure the bundle is of correct height to match the transformer. The machine has a base plate having a hole to receive the winding former. Bundles of laminations are removed from a stack held in a magazine and pushed into position by an actuator. Due to slight variations in thickness of individual laminations, the overall height of the bundle may vary. The end of the actuator is therefore provided with a height adjusting wedge to prevent uncontrolled movement of the topmost lamination.

Title: Removing odorous sulphur cpds. from waste gases or water - esp. in cellulose mfr. or in petrochemistry
IPC: B01D53/72
Filed: 1977-01-07
Abstract: An oxidn. soln. contg. water, an oxidant, and min. 0.3g.-/l. V2O5. The pref. oxidants are (a) an alkali metal chlorate, esp. over 100g./l. NaClO3; or (b) a peroxide. Powdered V2O5 is pref. first mixed with water to obtain a clear soln. of V2O5, obtd. esp. by calcining NH4VO3 in an air stream, and then the oxidant is added. Alternatively, the V2O5 may be dissolved in an alkaline soln. to which acid is then added, followed by the oxidant. The oxidn. soln. is pref. employed to oxidise organic cpds. in an aq. phase, esp. to eliminate odorous sulphur cpds. from residual gases and/or waste waters and condensates obtd. in the sulphate process for mfg. cellulose. The S-cpds. may be present in low concn. in an inert carrier gas; and the reaction prods. may be recovered by known methods from the soln. and made into commercial prods. Used for removing S-cpds. from inert gases in petrochemistry. The odorous and toxic cpds. are e.g., H2S, alkali sulphides, (CH3)2S, CH3SH. Process is simple and inexpensive, where the S-cpds. do not form SO2 gas, but form soluble prods. in the soln., the V2O5 acting as a catalyst.
