Title: Improvements in or relating to an adhesive for coating, penetrating, sizing, priming or waterproofing a base or backing, and/or for bonding grit to a base or backing to form with such base or backing an article in the nature of a flexible waterproof abrasive
IPC: C09D161/24
Filed: 1933-03-09
Abstract: Adhesives comprise the condensation products of an adehyde and urea and/or urea derivatives and/or an aromatic amine gelatinized by water-soluble non-alkaline salts having a high degree of electrolytic dissociation together with one or more flexibilizing agents. Suitable initial materials for the condensation products comprise urea, thiourea, monomethylol urea, dimethylol urea, carbodiphenylimide, S - diphenylthiourea, S - diparatolylthiourea, toluidine, xylidine, aniline together with formaldehyde, paraldehyde, or furfuraldehyde.  The aldehyde and urea or aromatic amine may be in approximately equal parts and when formaldehyde is used, approximately 2 to 5 parts of 40 per cent formaldehyde are used to each part of urea or amine.  The flexibilizing agents include aryl phosphates, e.g. tricresylphosphate, dibutylphthalate, triethanolamine, oil, preferably non-drying oils, as castor oil, polyhydric alcohols and glycols, e.g. glycerol and diethylene-glycol. These agents may be further modified by protein base glues, such as ordinary glue solutions.  According to an example, 60 parts urea, 150 parts of 40 per cent formaldehyde solution and 6 parts of hexamethylenetetramine are heated under a reflux condenser.  The product is gelled quickly by the addition of 2 parts potassium sulphate.  A flexibilizing agent or agents is added before condensation.  The product may be hardened by heating from 60 to 125 DEG  C.  The adhesives may contain 40-70 per cent resin, 0,1 to 5 per cent flexibilizing agent, the remainder being solvent, and are particularly useful for coating, sizing; waterproofing &c. a base or backing and/or bonding grit thereto to form a flexible, waterproof abrasive material.  Reference has been directed by the Comptroller to Specification 181,014, [Class 121].

Title: Process and apparatus for impregnating meat
IPC: A23B4/28
Filed: 1960-06-29
Abstract: 891,827. Impregnating/injecting meat HYGRADE FOOD PRODUCTS CORPORATION. June 29, 1960 [Jan. 26, 1960], No. 22750/60. Class 49. [Also in Group XXX] A meat product such as bacon bellies is impregnated with a liquid e.g. curing pickle, by contacting the surface of the meat product with a device comprising a duct of restricted cross-sectional area, one end of the duct intersecting the portion of the device in contact with the meat product, and feeding a liquid into the other end of the duct under high pressure thereby causing the liquid to discharge from the duct at high velocity, whereby the liquid is introduced into the meat product. The portion of the device in contact with the meat product may be a nozzle 45, Fig. 11, with a curved surface whose radius is at least one half the diameter of the shaft 36 of the nozzle; preferably, the diameter of the shaft is between 1/4 and 3/8 inch and the duct of the nozzle is cylindrical in shape having a diameter of 1/64 inch and a length of <SP>3</SP>/ 32  inch. For injection into fatty parts of meat such as bacon belly, a spiral insert 46 is inserted in the shaft to give a deep penetration and moderate distribution of the pickle; for lean parts, where shallow penetration and wide distribution are required, there is employed a solid cylindrical insert 48, Fig. 13, with diametrically opposed longitudinal grooves 49 of sufficient size to avoid objectionable back pressure effects and a recess or well 50 approximately 1/8 inch deep. Bacon bellies 13 are fed from a shoot 35, Fig. 3, into an injection machine 10 having a compartment 11 for injection by nozzles 32, 33, into the (lower) fatty sides of the bellies, followed sequentially by injection into the (upper) lean side by nozzles 32a, 33a in a compartment 12, Fig. 1. The bellies, which rest on spring rods 20, 20a, are conveyed by banks of rods 21, 21a mounted on eccentrically pivoted frames 22, 22a, Fig. 2, cyclically rising above and below the rods 20, 20a; the frames 22 and 22a in the respective chambers 11 and 12 are arranged to move in phase opposition to each other. Periodic contact of the bacon bellies over the nozzles 32, 33, by means of a pressure plate 37 and of the nozzles 32a, 33a upon the bacon bellies is achieved by the reciprocation by cams 42, 42a of rods 39, 39a, respectively, in phase opposition to the respective frames 22, 22a; pickle liquor is automatically supplied to the nozzles when they are in contact with the meat. The headers for each bank of nozzles 32, 33 or 32a, 33a are spaced 3 inches apart and the nozzles on each header have a 1 inch spacing; the bacon bellies are moved 2 inches between each pumping cycle. Drained pickle is collected on a tray 52, Fig. 3.

Filed: 1958-07-21
Abstract: 853,600. Aerials. ALFORD, A. July 21, 1958, No. 23330/58. Class 40(7). In order to increase the bandwidth of a directive aerial system comprising a primary element, or a plurality of primary elements, associated with a reflector the primary element or elements are in the form of flared slots fed at their narrowest end with the direction of flare arranged either towards or away from the reflector. Figs 1 and 3 show the construction of an embodiment utilizing four slot elements mounted in front of a plane reflector consisting of rods 31 extending between bars 32. The slots, of which three 5, 6, and 5<SP>1</SP> are indicated in Fig. 3 are formed between the central portions 1, 1<SP>1</SP>, and caps 2, 3, 2<SP>1</SP>, 3<SP>1</SP>, of aerial members that may be circular, ellipsoidal or of other regular or irregular shape. These members are connected centrally by electrically neutral supporting stems 4 to the main structure. A coaxial feed line 27, 28 feeds the system through a coupling arrangement 23, 24 from which four sub-feeders extend one to each slot. The sub-feeders extend through tubes (e.g. 19, 20) as far as the stems 4 and thence along the inside of the stems and the central parts of the aerial members to be connected across the narrowest ends of the slots. The slots are narrowest at the ends closest to the reflector and widest at the point furthest therefrom. If the circumference of the aerial member, measured round the slot is of the order of a quarter of the working wavelength or less the primary element radiation pattern has, it is stated, been found to be approximately omnidirectional whilst circumferences of the order of a half wavelength give a directional pattern having a maximum in the direction extending from the feed point through the widest part of the slots. In dimensioning the system described above for wide-band operation it is arranged that the directivity of the slots themselves is utilized at the upper end of the band whilst at the lower frequency end of the band the slots become omnidirectional and the reflector is spaced to give the required directivity. Dimensions, and an explanation of operation, are given in the Specification for an aerial system capable of operation over the band 300 - 1050 megacylces. In another embodiment (Fig. 6) two primary element slots flared towards a parabolic reflector 40 are shown, at lower frequencies the slots are omnidirectional and the reflector spacing is such that direct and reflected radiation add. At higher frequencies the major part of the radiation is reflected as the slots become directive and there is little loss due to cancellation of the reflected by the direct signal.
