Title: Elimination of backlash in differential gears - with active flanks of gear teeth maintained in contact by spring loaded pinions
IPC: F16H55/20
Filed: 1975-07-04
Abstract: The mechanism is used to eliminate backlash in epicyclic gear trains. The active flanks of the teeth of a differential gear are maintained in contact by arranging that the spacing between the pinions is controlled by spring pressure. The pinions are mounted in pairs on transverse shafts at right angles. An intermediate shaft at 45 deg. to the pinion axes carries sliding hubs which are connected via short connecting rods to the pinions. Disc springs ensure that the hubs are forced towards the centre, the pinions being forced outwards because of the relative spacings of the pivots. Adjusting nuts on the intermediate shaft allow the preload between pinions and crown wheels to be set as required.

Title: Treatment of effluents partic from animal houses - with swilling, water sepn. and recirculation and solids collection
IPC: A01K1/01
Filed: 1976-05-10
Abstract: An appts. for separating solids from liqs. in effluent disposal systems incorporates an inclined perforated screen on to which the effluent flows from a tank. The liq. passes through the screen in a spray and is recirculated, while the solids pass over the screen. The screen may be a single panel with several sections, or it may incorporate several panels, staggered or overlapping, adjustable angularly, with side walls. The suspension of solids in liq. is fed to the elevated tank by mechanical means, e.g. pumping. A supplementary liq. e.g. a coagulant, may be added to the effluent. Used partic. for systems handling effluents from byres, piggeries, stable and the other places where animals are kept. The system is automatic, easily put into operation, efficient and requires little maintenance. Little odour is produced and abad weather has little effect. There are no mechanical parts in the animal quarters.
Patent FR-2312754-A1 (FR)
Inventor: WEIDNER PETER F
IPC: F41A19/64
Filed: 1976-05-26
Abstract: In the case of high-voltage detonating devices on automatic canons for detonating caseless cartridges (7) which are provided with fuzing elements (9), detonation failures frequently occur as a result of combustion residues. Such detonation failures can be prevented by means of a device (11, 12) which produces a high voltage, which is supplied to the fuzing element (9) via a detonating electrode (6), using a high-voltage switch which is connected upstream of the detonating electrode or using a normalising spark gap, which is positioned upstream of a detonating electrode, in that the detonation takes place independently of combustion residues that are present.

Title: Hovercraft lift and propulsion system - has suspension motor running at constant speed once single main engine exceeds given speed
IPC: B60V1/00
Filed: 1976-06-10
Abstract: The method of energising a hovercraft vehicle with a rotating support mechanism and propulsion system is driven by one main engine. When the main engine speed increases the support only is driven. Above a certain engine speed the support equipment runs at constant speed. There are three pumps connected to the engine and one hydraulic motor driving the support equipment and two driving the propulsion equipment. In addition, there are two position distributors to the propulsion motors and a fluid reservoir. These distributors are acted on by engine speed, automatically to bring the propulsion motor to constant speed, once the engine speed has reached a given value.

Title: Decomposing polyvinyl alcohol in aq. soln. - by culturing bacteria belonging to Alcaligenes using polyvinyl alcohol as carbon source
IPC: C02F3/12
Filed: 1976-12-28
Abstract: The method comprises culturing bacteria belonging to Alcaligenes a culture medium contg. PVA as the carbon source. PVA in aq. soln. can be easily decomposed and the method can be adapted for disposing of waste water contg. PVA. A representative stock is Alcaligenes KP-12(FERM-P-3184); these bacteria can be collected widely from nature. When the stock is cultured successively in culture medium rich in nutrients, the utilisability for PVA of the stock is decreased. The addn. of yeast extract or corn steep liquor increases the multiplication velocity of the bacteria without giving harmful effect on the utilisability for PVA. The culture is practised at 20-37 degrees C and pH 6.0-8.0 under highly aerobic conditions and the decompsn. of PVA is completed in 2-7 days.
