Title: Sausage skin end-closure - application device
IPC: A22C13/00
Filed: 1973-02-15
Abstract: Puckered sausage skin is closed at one end; it is made from an edible substance, cellulose or a thermoplastic synthetic material. The closure is constituted by the puckered end, this is drawn together by press. stuck, at least partially, with an adhesive in the puckered state and then pressed together again. The closure is cheap and does not require foreign bodies, such as adhesive tapes, metal hooks or tied threads. The closing process is effected by means of a tool in the form of pincers, it serves to grip and draw together the puckered end of the sausage skin. A metallic tube distributes the adhesive while the ends of the pincers press the gathers together. Finally, the pincers push the closure into the opening of the skin and are themselves withdrawn. The adhesive is made from physiologically acceptable prods., such as gelatine, starch, gum arabic, casein or collagen. The end closure should not be too solid as this would prevent the easy expulsion of the sausage meat.

Title: Automatic injection syringe appts. for therapeutic liqs. - with electronic controlled step by step motor
IPC: A61M5/145
Filed: 1974-07-03
Abstract: Automatic injection appts. for liqs. is notably intended for the slow injection of a therapeutic prod. into the human body by means of a syringe for a period, longer even than 24 hrs. The appts. comprises a base with a cover. The upper part of the latter has two parallel slots as well as a clip which securely holds the body of a syringe in the horizontal posn. Horizontal columns, under the cover, support a carriage which pushes the piston of the syringe forward. Power is supplied by an electric motor, fed from the mains, the motor drives the carriage through a reducing gear and a transmission chain. A double lever passes through the slots and operates a clutch which grips the transmission belt and drives the carriage forward by a series of steps. A semi-conductor electronic circuit counts the maisn half-cycles; when the number counted corresponds with the number shown by the selector, a calibrated pulse is transmitted to the motor, which turns one step. Counting of the half-cycles starts again from zero until the next pulse is transmitted, and so on. When the injection is completed the carriage comes up against a stop; this switches the motor off and sounds an alarm. The drive is de-clutched and the carriage is quickly brought back ready for the next operation. Appts. is simple, flexible in use and very precise control is obtd. over a wide range of injection speeds.

Title: Continuous rotary drum drier - for wet coke, with electrostatic precipitator for dedusting waste heating gases
IPC: F26B20/00
Filed: 1974-12-17
Abstract: Continuous drying of wet granular material, particularly wet coke, by the known technique of passing it in co-current with combustion gases through a rotary drum, and separating the dust from the waste gases leaving the drum, but with the improvement whereby (a) the combustion gases enter the drum at a temperature such that the temperature differences between the waste gases and the dried granular material at the outlet of the drum is at least 80 degrees C, partic. 150-200 degrees C and esp. 180 degrees C. (b) after leaving the drum the dust-laden gases flow through a trickling layer of granular material of uniform moisture content, (c) the thickness of the layer and cross section of the trickling layer as well as the particle size range of the wet granular material introduced into the trickling layer is selected in such a way that a reduced pressure of 5-20 mm (w.g.) and pref. 10 mm (w.g.) is maintained in the rotating drum, (d) the waste gases leaving the trickling layer are cleaned using an electrostatic precipitator. The rate of revolution of the drum is kept low and the residence time of the matl. in the drum is short, while the waste gases enter the electrostatic precipitator at the optimum temp. for efficient de-dusting.

Title: Cone piston brake expander - has piston length automatically adjusted to take up wear of linings
IPC: F16D65/56
Filed: 1975-01-03
Abstract: The cone piston expander mechanism for the pistons of a brake shoe actuator automatically adjusts the piston lengths to take up wear of the brake linings. The actuator drive rod (6) forces the cone (10) between rollers (12, 13) bearing on ramps (16, 17) on the inner ends of the pistons (18, 19) in the usual way. An extension (20) of the end of the cone projects laterally and carries on a pivot (21) a frame (23) extending each way in the directions of the pistons. Arms of this frame parallel to the drive rod axis form racks (24, 25) which mesh with pinions (30, 31) cut on the inner ends of the pistons. The frame is guided by a link (32) pivoted in the body of the mechanism and can thus swing towards and away from the pistons against the pressure of springs (26, 27) engaging or disengaging the rack and pinions respectively and forming two ratchets. The shapes of the rack and pinion teeth ensure that the pinions are only driven when the drive shaft retracts. When the pinions are driven they rotate the pistons and this automatically screws apart the piston crowns which are mounted on threaded plugs (40, 41). The crowns themselves are prevented from rotating by grooves (42, 43) which locate on the brake shoes.

Title: Floating temporary breakwater for marine engineering projects - comprises submerged enclosure with orifice system controlling rise and fall by wave action
Inventor: FACON PIERRE JEAN ALPHONSE
IPC: E02B3/06
Filed: 1975-02-17
Abstract: The breakwater which gives an area of relatively calm waters to project off-shore engineering projects is sensitive to variations in level between the crest and trough of the waves and consists of an enclosure which is submerged and extends completely to the breast of the mass of water, i.e. below the minimum line defined by by the wave-crests. This enclosure is designed so that variations in hydrostatic pressure brought about by variations in level between the crest and the trough of each waves results in water discharging from the enclosure. This enclosure is so designed that increased wave height causes water to discharge which reduces the total mass of the enclosure and causes greater energy dissipation.

Title: Backflushing water filter cartridge for drip irrigation - using filtered water from a second filter in parallel with the first
IPC: B01D36/04
Filed: 1975-03-03
Abstract: A filter system installation and the installed filter are claimed of the type in which the filter case houses a cylindrical filter cartridge and is provided with a drain valve. A stop valve is fitted in the supply line upstream of the filter and a finely perforated spray tube inside the case to backwash the cartridge after the stop valve has been closed and the drain valve opened. Pref. the filtered water outlet is via a pipe extending axially up the middle of the cartridge, and spray tube backwash water is supplied by reverse flow through the outlet pipe of water filtered by a second filter piped up in parallel with the first. The drain valve and stop valve are pref. motorised and the backflush operation initiated automatically when cartridge blockage is detected. The backflush operation does not require compressed air or high pressure water, so additional compressors or pumps are not required; instead a second filter installed in parallel with the first provides the backflush fluid and is, in turn, backflushed by water filtered through the first filter.
