Title: Improvements relating to the production of glass fiber mats
IPC: D04H3/02
Filed: 1960-07-13
Abstract: 923,972. Producing glass fibres; maintaining level of molten glass. AMERICAN AIR FILTER CO. Inc. July 13, 1960 [July 13, 1959], No. 24396/60. Class 56. Apparatus, for the production of glass filamentous mats, of the type including a reciprocating furnace which is moved axially of a rotating drum and in which a plurality of filaments is drawn from orifices associated with the furnace and fed on to the surface of the rotating drum to build up a cylindrical filamentous mat thereon and including means for weighing said furnace and its contents, comprises a supply material hopper and electric switches responsive respectively to a predetermined departure of the weight of the furnace and its contents from a predetermined value and to the position of the reciprocating furnace relative to the hopper, and means responsive to coincident actuation of the switches to cause transfer of material from the hopper to the furnace. In the form shown, fibres are drawn from orifices at the bottom of a furnace 28 and wound on to a rotating drum below it while the furnace is reciprocated on a carriage 10, running on a track 14, as described in Specification 846,624. The furnace is carried on a frame 32 supported on the platform 22 of a weighing-machine 20. A contact 34 is closed by the arm 26 of the weighing-machine when the weight of the furnace falls by a predetermined small amount from a datum. At each traverse of the furnace an arm 38 thereon strikes the actuating arm 66 of a spring-loaded gate 60 of a hopper 40 from which the furnace is replenished with oullet through a hopper 30. No material is fed, however, until a vibrator assembly 56 is actuated by air fed through a solenoid-operated valve 70 which is opened only when the switch 72 is closed by the furnace and the end of its movement and also when the contact 54 is closed. The weight of the furnace is thereby maintained close to the datum value. The hopper 40 is itself carried on a platform 42 of a weighing- machine 44 the arm 48 of which co-operates with the contact 50. The latter can be set to close after a predetermined loss in weight of the hopper 40 and to operate an alarm signal to indicate that this weight of fibre has been wound on to the drum. U.S.A. Specification 2,798,531 also is referred to.

Title: A process for preparing condiments
IPC: A23L27/24
Filed: 1960-07-18
Abstract: A condiment for enhancing the taste or flavour of foodstuffs is prepared by extracting yeast with an aqueous solvent, separating water-insoluble matter from the extract, hydrolysing the yeast extract by means of a phosphodiesterase-containing enzyme system of a microorganism, if necessary removing from the thus obtained hydrolysate any toxic components and components having unpleasant taste or odour, and admixing the resultant composition with a hydrolysate of the water-insoluble matter obtained from the extraction of yeast.  The hydrolysis of the nucleic acid in the yeast extract to produce 51-nucleotides is described and claimed in Specifications 912,790 and 933,826.  According to an example, ten kilograms of dried brewery yeast is extracted under heating at 90 DEG C. for 4 hours with 150 litres of a 3% saline solution the pH of which had previously been adjusted to 8.0 with sodium hydroxide; the extract is then separated centrifugally from insoluble matter.  To 150 litres of the yeast extract there is added 50 litres of a culture filtrate of Streptomyces griseus and hydrolysis is carried out at a temperature of about 40 DEG  C. for 15 hours.  The hydrolysate is filtered after 500 grams of diatomaceous earth have been mixed with it; the filtrate is passed through a column of ion exchange resin and then is neutralized. The insoluble matter is boiled for 20 hours with 20 litres of dilute hydrochloric acid and is then filtered, neutralized with sodium hydroxide and admixed with the neutralized effluent from the ion exchanger.  The mixture is concentrated under reduced pressure and spray dried to obtain 700 grams of a powdery condiment containing various amino acids together with 51-guanylic acid, 51-inosinic acid and other 51-nucleotides.  The Specification mentions other yeasts and micro-organisms, and specifies suitable ion exchange resins. Specification 933,827 also is referred to.

Filed: 1944-12-15
Abstract: 584,214. Variable-speed epicyclic gearing. DAIMLER CO., Ltd., and TAIT, J. N. H. Dec. 15, 1944, No. 25172. [Class 80 (ii)] In a variable-speed gear for automobile transmissions of the type having three epicyclic trains of spur gears which are compounded together to give various speed ratios, the drive issuing always from the planet carrier of the first train, two further trains are added to give a reverse and an overdrive respectively. As shown, the planet carrier 9 of the first train 3 is secured to the driven shaft 15 and carries planets 7 meshing with a sun 5 keyed to the driving shaft 1 and with an annulus 11. The planet carrier 21 of the second train 17 carries a gear 23 meshing with the annulus 11, and its planets 19 mesh with the sun 5 and with an annulus 25 connected tu the planet carrier 37 of the third train 29, whose planets 31 mesh with an annulus 35 connected to the carrier 21 and with a sun 33 freely revoluble on the shaft 1. The reverse train 45 comprises a sun 47 integral with the sun 33, and an annulus 57 keyed on the shaft 1, both meshing with the planets 49 keyed on the carrier 51. The annulus 57 also forms the planet carrier of the overdrive train 59 whose planets 61 mesh with an annulus 63 integral with the carrier 51 and with a sun 65 free on the shaft 1. Brake mechanisms 13, 27, 43, 55 and 71 coacting with brake drums mounted on annuli 11, 25, sun 33, annulus 63 and sun 65 respectively are operated singly in turn to bring in the different speed ratios. The first, or lowest, speed is obtained by locking the annulus 11 and using the train 3, the second speed by locking the annulus 27 thus compound ing the trains 17, 3, and the third speed by locking the sun 33 and compounding the trains 29, 17 and 3. The reverse drive is obtained by locking the annulus 63 and therefore the carrier 51, so causing the sun 47 to rotate oppositely to the shaft 1, the motion being compounded with that of the trains 29, 17 and 3 to rotate the shaft 15 reversely. The overdrive is engaged by locking the sun 65, the resultant motion of the annulus 63 being compounded with that of the other trains to cause the shaft 15 to rotate faster than the shaft 1. A direct drive is provided by clutching the brake drum member 69 mounted on the sun 65 to the shaft 1 by means of a multiplate clutch 73, which locks the gears giving a solid drive. Specifications 164,042 and 329,277, [both in Class 80 (ii)], are referred to.
