Title: Improvements in or relating to cathode-ray oscillographs for use in television
IPC: H03K4/92
Filed: 1934-01-22
Abstract: 424,093. Television. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and JESTY, L. C., c/o General Electric Co., Wembley, Middlesex. Jan. 22, 1934, No. 2190. [Class 40 (iii)] Scanning equivalent to that produced by saw-tooth wave-forms is obtained by deflecting each of a plurality of cathode rays with sinusoidal oscillations, the oscillations being of equal frequency but phase displaced relatively to each other. Three oscillations, a1, a2, a3, each phase displaced by 60‹ from its predecessor, each deflect a separate cathode ray tube. Each scanned screen is masked to cut off the extremities of the paths traced by the cathode rays so that only the linear portions l of the oscillations are effective for scanning. Each cathode ray in turn traces a scanning line, first in one direction, e.g. from left to right, and then in the reverse direction, from right to left. The three scanned screens are optically combined, e.g. by projection so that the final screen is continuously scanned by cathode rays whose direction is reversed every three lines. Each cathode ray tube may produce a separate colour, the combined image then having different lines differently coloured. The oscillations a1, a2, a3 may be phase displaced by 120‹, the direction of the scanning lines of the final screen reversing at the end of each line, Fig. 2, (not shown) ; two oscillations, phase displaced by 90‹, may be used to give a scanning in which the direction is reversed every second line, Fig. 3, (not shown). The screens may have optical absorbing matter near the edges to reduce the brightness produced by the departure from linearity of the deflecting forces.

Title: Improvements in packaging machinery
IPC: B65B11/02
Filed: 1951-01-30
Abstract: 693,716. Wrapping machines. HOLLIS, A. C. Jan. 29, 1952 [Jan. 30, 1951], No. 2270/51. Class 94(i). A wrapping machine includes apparatus for wrapping a wrapper length about a stationary object to form a centre seam in the wrapper length, said apparatus being adapted to unfold to form a substantially level surface to allow the partially wrapped object to be pushed therefrom for subsequent end-folding operations. Rollers 13, driven intermittently through a unidirectional coupling 14 from a reciprocated chain 6, feed a web 12 of wrapping material to a flat table 1 ] where a wrapper is cut from the end of the web by a camactuated knife 16. A square-angled article is transferred by swinging grippers 44 from the base of a chute 50 on to the wrapper on the table 11 preparatory to the folding operation. The grippers 44, which are linked to move together, are loosely mounted on a driven shaft 45 to which is secured a drive disc 46 formed with an arcuate slot 47 with a chamfered face 48 and adapted to drive the grippers 44 through a radial rib on the hub of one of them. Thus when the rib engages the recess 47 a spring is allowed to move the grippers 44 together to hold the article and, as the rib engages the chamfered face 48, the grippers are swung to deposit the article on the wrapper, where resistance to further swinging movement causes the face 48 to over-ride the radial rib causing the grippers to move outwardly and allowing a spring 51 to swing them back to the article receiving position. Hinged folding plates 18, 20 on one side and plates 19, 21 on the other side of the table 11 lie in their inoperative position, flat in the plane of the table 11 and are so linked together and lifted by cam actuated pushrods 22, 23 as first to fold the wrapper up the sides of the article into a U and then to fold the arms of the U on to the top of the article, Fig. 6. The plate 21 moves a little before the opposite plate 20 to allow one edge of the wrapper to lie on the opposite edge to form a centre seam which is heat sealed by a hot edge member 35 on the plate 20, heated by contact with a heating element 35<SP>1</SP> when the folders are in their flat, inoperative position. The folders being in this position, the partially wrapped article is moved thereover into end folding means 37 by a push plate 36, carried by a member 38 pivoted on a member 39 reciprocated by the chain 6, which has a dwell period at the ends of its reciprocating strokes. Ears 36<SP>1</SP> spring-urged apart on the pusher 36 are moved in by engagement with ramps 37<SP>1</SP> at the entrance'to the means 37 to form the rear end tucks. The pivoted arm 38 is lifted in its rearward stroke by engagement with a pivoted ramp 40 to allow the pusher 36 to clear the succeeding article.

Patent GB-587572-A (GB)
Title: Improvements relating to the finishing of textiles
IPC: C07C275/14
Filed: 1944-02-09
Abstract: Textiles are finished by impregnating them with an aqueous solution of a quaternary nitrogen salt of a melamine formaldehyde condensation product and decomposing the salt by subjecting the textiles to heat at temperatures above 80 DEG  C. and setting the resin on the textile fibres.  Methylol melamines or their alcohol reacted products are used in their uncured state in preparing the quaternary nitrogen salts, i.e. in unpolymerized or only partially polymerized products of general formula <FORM:0587572/IV/1> <FORM:0587572/IV/2> where A is -NH2, NHCH2OR or -N(CH2OR)2, B is -NH.CH2OR or -N(CH2OR)2, R1 is hydrogen or CH2OR, R is hydrogen or an alcohol forming radical, Mx represents the nucleus of a partially polymerized melamine - formaldehyde condensation product.  In the alkylated products the alcohol used may be methyl, ethyl, propyl, isopropyl, butyl, isobutyl, amyl or isoamyl, but the water repellancy of the product is improved by using a higher aliphatic alcohol such as octyl, decyl, dodecyl, tetradecyl or octadecyl alcohols.  Cyclo-aliphatic and aliphatic alcohols, e.g. cyclohexanol and benzyl alcohol respectively may be used.  The more important classes of nitrogen bases to be condensed with the monomeric or uncured melamine formaldehyde products described above include the two of the formul <FORM:0587572/IV/3> <FORM:0587572/IV/4> where X1, X2 and X3 are alkyl radicals, Z is the residue of a pyridine base, Y is an anion, e.g. chlorine, bromine and iodine.  The salts are prepared by heating the melamine-formaldehyde and tertiary nitrogen compounds together at temperatures not substantially higher than 80 DEG  C., methanol or ethanol being present if desired.  Salts of pyridine bases react quickly with the melamine-aldehyde condensation products at 50-70 DEG C.  The salts are applied to the textiles in aqueous solution either alone or mixed with other materials, e.g. monomeric methylol melamines or their water-soluble methyl ethers, water-soluble methylol ureas, curing accelerators such as acid salts of phosphoric acid, hexamethylene tetramine, starches, gums and sulphonated oils. The textiles are impregnated by immersion, spraying or other mechanical means, then suspended in a drying oven at temperatures preferably between 240-300 DEG  F.  The cloth is washed with aqueous soap solution containing sodium carbonate. Cotton, linen, wool, viscose, cellulose acetate, spun rayon and silk may be satisfactorily treated as above.

Patent GB-192696-A (GB)
IPC: H01F38/18
Filed: 1923-01-30
Abstract: 192,696. Signal Ges. Feb. 1, 1922, [Convention date]. Addition to 172,637. Subaqueous audible signals.-In a receiving device for subaqueous sounds, wherein the diaphragm is loosely coupled to the detector, as described in the parent Specification, the diaphragm has a diameter of more than ten centimetres. The diaphragm and the mass around its edge are constructed from one piece of material, and in the form shown in Fig. 1, in which the diaphragm 2 forms part of a casing 1, it is constructed in one piece with the latter. The loose coupling between the diaphragm and the detector is obtained by making the mass of the detector attached to the diaphragm greater than the freely vibrating mass in the ratio of at least 10 to 1. In the example shown in Fig. 1, the diaphragm has an annular projection 3 into which is screwed the casing part 5 of the microphone with the interposition of an insulating ring 4, whilst the second electrode is mounted on a diaphragm 7 held by a cover 10. This mounting includes non- axial vibrations. In the case of an electromagnetic detector, Fig. 4, the field magnet 23 is attached to the diaphragm, the small mass being constituted by a coil 24, or an armature elastically mounted. Such a detector mav be combined with a similarly constructed telephone receiver and, owing to use of permanent magnets, the system needs no batteries. The diaphragm and detector are tuned to the same frequency, and the frequency range due to coupling agrees with the range of frequencies to be received. The Specification as open to inspection under Sect. 91 (3) (a) states that the diaphragm oscillates in the form of its fundamental. This subject-matter does not appear in the Specification as accepted.

Title: Improvements connected with automatic voltage regulators for dynamo electric machines
IPC: H02P9/20
Filed: 1943-02-22
Abstract: 565,355. Automatic control systems. STONE & CO., Ltd., J., and NIXON, L. R. Feb. 22, 1943, No. 2885. [Class 38 (iv)] Voltage.-A voltage regulating system having an electromagnetically operated variable resistor, such as a carbon pile or multiple - contact type resistance, in which the force movement characteristic of the magnet system is substantially rectilinear and the spring characteristic is steeper than the magnet characteristic to render the system non-astatic, has compensating means in the circuit of the resistor to increase the excitation of the magnet as the resistance increases. In one arrangement, the magnet has a second winding R<SP>2</SP> acting in opposition to its main winding R and connected in series with the resistor P. As the resistance increases the effect of the opposing winding becomes less, the resultant excitation being increased. In another modification, a fixed resistance is connected in series with the resistor P and the winding R connected to a tapping between them. The voltage applied to the winding thus increases when the current through the fixed resistance diminishes owing to an increase of the variable resistance. The result is a voltage control equivalent to that of an astatic balance of the forces of the magnet and spring, without its instability.
