Title: Nutritional products from skim milk with higher lactose conversion - as additives to baking doughs or to animal fodder (BE050476)
Inventor: HOLT WILLIAM R
IPC: A23K10/28
Filed: 1975-10-06
Abstract: A technique for the manufacture of a product from skim milk, in which a relatively higher proportion of lactose is converted into lactic acid, operates by (a) inoculating a skim milk containing less than 10% of solids, at a temperature of 32,2 to 54,4 degrees C, with a culture of a mutant of a lactobacillus having the characteristics of lactobacillus bulgariscus and lactobacillus acidophilus, being capable of converting lactose into mainly left rotation lactic acid, being aerobic and microaerophilic, viable at a pH value of 3,2; having the form of minute rods, and dyeing off in a weakly alkaline environment. The strain used is obtained by repeated cultivation of skim milk from cheese making, and grows on tomato agar, forming colourless, smooth, flat, round colonies beneath the surface (b) fermenting the inoculated skim milk at least once, at a temperature between 26.7 and 54.4 degrees C whilst blowbing in air, agitating and continuing the operation until the pH value falls to 3,2 to 3,8 c) reducing the liquid content of the milk at least once by vaporising under vacuum to reach a solids content of 40 to 52%. Replaces in baking, all the milk products as well as a large pasrt of the egg products. Increases the keeping qualities of the baking products to five days, reduces the cost, improves the taste.

Title: Pressing liq. from sludge esp. sewage sludge - in decreasing gap between two rising surfaces e.g. drum and belt
IPC: C02F11/123
Filed: 1976-03-11
Abstract: The sludge is sandwiched between two moving surfaces which carry the sludge continuously upwards. The gap between the two surfaces becomes progressively less from inlet to discharge, so that pressure on the sludge is gradually increased and liq. expelled. Liq. expelled laterally of the surfaces is pref. blown away into a collector, e.g. by jets of compressed air. One or both surfaces can be impermeable or made up of a filter screen. The installation pref. comprises a rotary drum with an impermeable circumference to form one of the two pressing surfaces. The other pressing surface is provided by the outer face of a continuous conveyor band, pref. perforated. The band extends tangentially and horizontally from the lowest part of the drum circumference to provide a feed extension on to which sludge can be loaded. From this lowest part of the drum, the band continually approaches the drum surface, following a rising path until it moves away over a drive pulley. This simple, robust installation expels interstitial liq. laterally as well as through filter screens and is therefore not impedded to the same extent by blockage of the screen.

Title: Automatic cleaning of rotary fibre processing element - using brush which itself is cleaned by rotary comb and suction device
Inventor: GROSSI OSCAR
IPC: D01H5/60
Filed: 1976-03-25
Abstract: A rotary element (e.g. opening or combing rollers) of a textile machine is cleaned by a cleaning brush in peripheral contact with the rotary element and mounted within a housing having an exhaust duct connected to a suction device. Also mounted within the housing is a comb which rotates and which is mounted within a rotating cylindrical casing. The teeth of the comb, project through holes in the casing. The axis of rotation of the comb is eccentric w.r.t. the axis of rotation of the casing so that as the casing and comb rotate, the teeth project from the casing in the region, of the brush, to penetrate the tufts of the brush, and collect waste fibres removed from the rotary element. Further rotation of the casing and comb, causes the needles to withdraw into the casing in the region of the exhaust duct.

Title: Multiple saws for radial slotting of plastics pipe - using gang saws with automated rotation or convergence (BR051076)
Inventor: HOPF DIETER
IPC: B26F1/00
Filed: 1976-04-08
Abstract: Equipment for slotting plastic tubing radially is claimed. Gangs of rotary saws or knives mounted on one or more oscillating axles cut into the pipe surface externally. The pipe is advanced in stages between cuts. The pipe may be rotated to accept circumferentially spaced cuts if the saws do not converge along sufficient radii during each cut. Used for mfr. of ground drainage pipe etc. Gang saws offer higher throughput rates than use of single saws. Use of automate convergent saws or automated pipe rolling is more efficient and reproducible than manual rolling to stagger slots circumferentially. The saw shaft cradle allows simple interchange of different patterns and spacings of saw blades.

Patent FR-2369039-A1 (FR)
Title: Continuous casting of vertical strands - in which induction motors oppose the descent of the strand
IPC: B22D11/128
Filed: 1976-10-29
Abstract: In the continuous casting of vertical or near vertical strands, the strand is removed continuously from the lower end of a continuous casting mould, and during its descent from the mould, the strand is moved between electromagnetic induction devices which exert on the strand a force tending to oppose the descent of the strand. The induction devices are centred with respect to the strand and are located a predetermined distance from the surface of the strand. The conventional dummy bar used to start the cast can be of shorter length than is usual so the mould can be located near to the ground. In addition, the motor-driven extractor rolls can be located nearer to the mould with little fear of piercing the strand crust. The arrangement is particularly useful where the strand is cast with an axial rotation motion.
