Title: Improvements in or relating to clutches
Inventor: ENGELBRECHT HELMUT
IPC: F16D25/0638
Filed: 1966-07-13
Abstract: 1,107,776. Friction clutches. INSTITUT FUR SCHIFFBAU 13 July, 1966, No. 31493/66. Heading F2C. The friction discs 5 of an hydraulically actuated disc clutch are urged into engagement by pistons 8 rotating with the clutch and acting on a spring loaded thrust ring 9 which carries a locking bolt 17 in a T-groove 16, which bolt co-operates with a stop ring 34 on the clutch hub 2 to maintain the clutch engaged on releasing the hydraulic pressure in a known manner (not described). The clutch is disengaged by reapplying, and subsequently releasing, the hydraulic pressure. The locking bolt 17 is spring biased toward a pawl .18 free to slide in the groove 16 between two radially separated stops (23), (35), Fig. 3 (not shown), the pawl being spring biased towards the outer stop (23), and the piston 8 carries a secondary piston (27), the nose (30) of which, on driving the piston 8 toward the clutch discs, enters between the bolt and pawl and, on the ring 9 being forced towards the discs by a sufficient amount, causes the bolt to be received behind the stop ring 34. On releasing the hydraulic pressure, the pistons are withdrawn, the bolt remaining clamped behind the stop ring 34, and the pawl 18 springing down against stop 35 into a position such that on reapplying the hydraulic pressure, the piston 27. abuts the pawl 18 and hence, on moving the thrust ring towards the discs 5, allows the locking bolt 17 to spring out from behind the stop ring 34. On releasing the hydraulic pressure, the clutch is disengaged and the pawl and bolt spring back to their initial positions. The stop ring 34 is made as a threaded ring to allow adjustments of the clutch for wear. To render the locking means inoperative, a ring (36), Fig. 8 (not shown), may be provided to hold the pawl 18 in its inner position blocking the piston 27, so that the clutch disengages immediately the hydraulic pressure is released, as is well known.

Title: Process for obtaining fats, fatty oils, and protein products from offal, garbage or other animal or vegetable products
IPC: C11B13/00
Filed: 1937-11-17
Abstract: 505,844. Extracting fats from offal, garbage, or other vegetable or animal products. HANESCHKA. H., and VERMES, J. Nov. 17, 1937, No. 31600. Convention date, Nov. 17, 1936. [Class 91] Oils and fats are recovered from animal or vegetable raw materials, especially garbage or offal, by treating at elevated temperature and under pressure with ammonia and primary ammonium phosphate. The aqueous layer containing emulsified fat is separated by centrifuging, leaving an aqueous protein-containing broth which is dried and worked up to form a fodder meal. In an example, 1000 kg. slaughter house garbage, whale flesh, fish offal, cereals, or cattle cake residues, are fed into a container together with 12 to 20 kg. of concentrated ammonia and up to 2 kg. of primary ammonium phosphate. The container is closed and steam introduced to generate a pressure of 3 atmos. After 25 to 40 minutes with stirring there is formed a protein-containing broth in which the fat is emulsified, and free acids are neutralized. If it is desired to digest insoluble proteins or to destroy the protein, the boiling is prolonged to from 1 to 2 hours. Excess of ammonia is blown out and recovered. The aqueous layer is then fed to a centrifuge, from which the fat is recovered, and the aqueous layer is dried to form a fodder meal.
Patent GB-601295-A (GB)
Title: Improvements in or relating to the generation and control of oxygen
IPC: C01B13/02
Filed: 1945-11-23
Abstract: In a method for the generation and control of oxygen suitable for respiratory pur <PICT:0601295/III/1> <PICT:0601295/III/2> poses in vitiated atmospheres and produced by burning self - combustible oxygen-yielding material, separate portions of the material are electrically ignited consecutively so that they are burnt one at a time and the pressure of the oxygen evolved from each portion in turn, except the last, is utilised to control a pressure-responsive mechanism which automatically effects ignition of another portion when that previously ignited becomes spent and the oxygen so produced is treated to remove impurities. As shown, the apparatus employed comprises a combustion chamber 2 containing a removable magazine composed of an assemblage in a ring of six symmetrically disposed stainless steel openwork tubes 6, each charged with a self-combustible oxygen evolving candle of the chlorate-peroxide type and having individual electrical heating elements 8 mounted in a recessed block 9 of ceramic material fitted into an aperture in the cover 3 of the said chamber.  The heating elements are fired by an ignition switch with spring contacts 78, Fig. 4, in series with a ratchet controlled rotary selector switch (not shown).  Closure of the switch initiates ignition of the associated candle, the evolved oxygen passing through openings 36, Fig. 3, in the corresponding tube 6 into the combustion chamber 2 and leaving the bottom of this through an aperture 37 and pipe 38 to the base of the precooler 39 and hence along the overhead pipe 40, Fig. 4, to the second precooler 41, Fig. 3, and via the gland 43 in sequence through the filter units 44 and 45, Fig. 4.  These comprise a coned sleeve 48 of sintered glass clamped between rubber washers 49 and 50 located in circular plates 51 and 52 which are interconnected by means of the clamping screw 53, the filter element being finer in unit 45 than in unit 44. From these units the oxygen passes into a chamber 47 in the upper part of which there is a piston 70 having a small clearance with the wall of the chamber, thereby initially allowing the oxygen to leak past the piston to the top of the chamber 47 and out to the surrounding atmosphere through the holes 71.  When the pressure of the oxygen is sufficient, however, the piston 70 is raised until the annular port 72 registers with the outlet port 73 in the wall of the chamber 47, thereby allowing the purified oxygen to discharge through the orifice 76 of the outlet unit 74 into the surrounding atmosphere. The leak past the piston 70 permits the piston to actuate mechanism (see Group XXXVII) by means of which the candles are automatically ignited in succession as one by one they become spent.
