Patent DE-2430481-A1 (DE)
Title: Electronic flash gun charging arrangement - with some magnetic energy retained in the transformer core, decreased time to charge storage capacitor
Inventor: OGAWA FRANCIS T
IPC: H02M3/338
Filed: 1974-06-25
Abstract: The object is to decrease the time taken to charge the storage capacitor which provides the energy for the flash tube. The capacitor is charged to typically 350 volts from a primary battery of a few volts via an inverter and transformer. To increase the charge rate the transformer core is not permitted to give up all its energy during the charging half cycle before the remagnetising half cycle recommences. As the demagnetising, or charging, follows a natural growth law the bulk of the stored energy is transferred at the beginning of the half cycle. By remagnetising before full decay has taken place the capacitor recharging time can be cut to about half that required by a hitherto conventional charging circuit having full decay of transformer flux.

The frame can comprise three or more radial arms of flat vetical section hooking under the edges of the bin mouth, some of the hooks pivoting between the free and engaged positions and being locable in the latter.
Patent DE-2436996-A1 (DE)
Title: Carbon dust compression machine - vibrator has two shaft control drive
Inventor: JAKOBS WILLY
IPC: F16H3/72
Filed: 1974-08-01
Abstract: The control drive is used for the generation of linear oscillations by means of two contra-rotating eccentric masses, the drive shafts of which are linked. The oscillations are used e.g. to shake carbon dust which is loaded by weights into pockets to form electrodes. The drive system consists of two parallel shafts. The first shaft is driven by an electromotor. A hydraulic controller is also connected to this shaft by a one to one gear drive. The first shaft is connected by a toothed belt to the second shaft which is driven by a hydraulic motor. Hydraulic motor and hydraulic controller are interconnected, so that the hydraulic motor will drive the second shaft at the same speed as the first shaft.

Title: Pulsating fuel injector for diesel engines - has pressure applied to injector plunger via pneumatic connection to engine
Inventor: MOIROUX AUGUSTE
IPC: F02B3/06
Filed: 1975-03-14
Abstract: A free piston divides a cylinder into two parts, one working as a normal compression ignition engine with a direct injection system actuated by compressed air. The second chamber is filled with air which acts as a return spring to the piston. The injector pump consists of a pneumatic plunger regulated by the lower part of the piston provided with an inner chamber between the recessed outlet walls of the piston and the cylinder. The length of the recess is the same as the difference between the largest and smallest piston stroke. When the piston reaches b.d.c. compressed air enters the inner piston chamber and is able to move the pump plunger when the inner piston chamber outlet aligns with the plunger communication passage.

Title: Magnetic hover track half side guided vehicle - with reversed compressed air guidance facilitating high speed negotiation of rigid junction points
Inventor: HARTUNG HEINZ
IPC: B61B13/08
Filed: 1975-05-20
Abstract: The vehicle travelling on the magnetic hovertrack are carried and guided on one half side, whether for passenger or goods transport, so as to make it possible to guide them through rigid junction points at high speeds. At the same time the combination of a number of controlled electromagnets, operating at different levels, facilitates the provision of extremely smooth hover motion, even when very heavy loadings are involved. The vehicles are compressed-air guided and borne without contact, with the air guiding acting directly on the potentiometers of the carrier and guide magnets. Reversed compressed-air guiding permits a change in direction at rigid junction points, at high speeds.

Planet wheels are located between the drive shaft and the wheel, in needle bearings in the chassis support, and drive an inner gearing cut in the wheel rim. The two bearing support allows large loads to be carried by the wheel, which is solid tyred. The planet wheels can be left out if the wheel is non driven. The system has a large reduction and is suitable for rotating booms in sewage works or other slowly moving equipment. The solid tyres are either pressed on the rims or are vulcanised in placed.

Title: Thermal reactor for completing combustion of IC engine exhaust - has flame holder welded to casing and projecting into combustion chamber
Inventor: SCHELLMANN KLAUS DIPL ING
IPC: F01N3/26
Filed: 1975-09-02
Abstract: The thermal reactor for completing combustion of IC vehicle engine exhaust gases is for engines with two (9, 10) or more separate exhaust stubs coming together to form a common outlet/inlet (11) to the reactor. The reactor casing (2) is dished (6) around that junction (4) to a shape which permits a gastight (welded) joint (13) to be made. A flame holder (14) also welded to the casing (15) projects into a combustion hamber (3) within the reactor through an opening (5) in the chamber wall. The single outlet pipe from the reactor and the stub pipes between cylinder head and reactor are so connected and separately supported as to free the reactor from any outside mechanical loading. However, they nevertheless absorb any relative movement between cylinder block and reactor, due to differing thermal expansion.

Title: Gravity operated davit for inflatable boat - with pivoted supports for flat bottom of boat secured in place by ratchets
IPC: B63B23/16
Filed: 1975-12-22
Abstract: The flat bottomed inflatable lifeboat is slung from davits (14) which run down an inclined track at the side of the ship, to sling the boat over the side. In the storage position the underside of the boat is supported on horizontal arms which are dropped into the track as the boat is released. The arms are linked to pressure arms on the side of the davit, which are pressed as the boat is hauled in. This raises the arms under the boat, in which position they are secured by ratchets. Several arms are spaced under the length of the boat for the best possible support. The boat can be launched even with a severe list on the ship.

Title: Photosensitive measurement of liq. colour - uses controlled collimated beam directed through liq. and lens to photocell
Inventor: PFEIFER KURT ING GRAD
IPC: G01N21/25
Filed: 1976-04-26
Abstract: A transducer is used for measuring the colour or transparency of a liquid. A light beam of controlled intensity is directed through the liquid to a photosensitive detector. The device can be used to find concentrations of solvents in liqs. such as solutions of plutonium nitrates in atomic generating plant. A lamp (2) and convex alternating lens (8) mounted in an outer case (1) produce a light beam which is directed through a half reflecting mirror (9). The reflected beam falls on a photosensitive detector (10) to produce a signal used to control the source (2) energy which the remaining beam is filtered (11) and directed through a flat cavity formed by two parallel glass plates (19, 20) and containing the liquid concerned applied and drained through suitably attached pipes (17, 18). A photosensitive detector (21) produces the measurement signal required. The liquid supply pipes (17, 18) and light source (2) are easily exchangeable.

Title: Non:slipping rope haulage system - uses clamping roller for guiding and movement
Inventor: MEHNERT WALTER DIPL ING DR ING
IPC: B66D1/74
Filed: 1976-08-05
Abstract: The non-slipping rope haulage system uses a clamping roller to guide, move and control the rope, which is reeved round it through an angle of less than 360 deg. The rope can be moved and controlled either direct by hand, or by a mechanism, at whose input force acting on the cable is reduced and/or altered by slippage. The roller can guide the rope in both directions, letting it free when pulled off, and securing or releasing it under load. To move and control the rope, the main and auxiliary mechanism can be moved in three directions at least.
