Title: Improvements in or relating to television systems
IPC: H04N3/16
Filed: 1946-08-29
Abstract: 624,099. Television systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 29, 1946, No. 25966. Convention date, Dec. 19, 1940. [Class 40 (iii)] An arrangement for generating a scanning current or voltage (e.g. for use in a television system) comprises a cathode-ray tube, the electron beam of which is deflected across the fluorescent screen at a predetermined frequency, a photo-electric cell adjacent the fluorescent screen and a filter, the transparency of which varies across its surface, interposed between the fluorescent screen and the photo-electric cell. As applied to a television receiver, the arrange. ment includes a cathode-ray tube 4, light from the fluorescent screen 6 of which, after transmission through the variable transparency filter 8, is directed by lens 9 on to photo-electric cells 10, 11 between which is positioned an opaque screen 14 to divide the light transmitted through the filter into two parts corresponding to two different filter transparencies arranged to generate two different scanning waveforms (e.g. for line and frame scanning), the waveforms thus generated across resistors 12, 13 being fed to the appropriate deflection means of the television receiver 1. Since a similar screen is employed to generate the scanning waveforms of the transmitter, secrecy of transmission is ensured. The electron beam of tube 4 is deflected by means of a pilot wave (from the transmitter, or from electric mains if common to transmitter and receiver) and applied to a deflecting coil 7, a rectilinear image of the cathode being formed on screen 6 perpendicular to the line dividing the different filter transparencies. Additional secrecy is ensured by replacing the filter 8 by a moving film, the transparency of which varies according to a predetermined law. A method of producing a filter of varying transparency by means of a " Dufour " oscillograph is described.

Title: Urethral catheter applicator
IPC: A61M25/01
Filed: 1971-04-19
Abstract: 1344357 Urethral catheter D H KUNTZ 19 April 1971 [25 March 1970] 26030/71 Heading A5R A urethral catheter applicator device 10 comprises a container for storing a catheter 22, an opening through which the catheter 22 may be withdrawn from said container, and relatively reciprocable elements 14, 18 adjacent the container for withdrawing the catheter for application to a patient. One embodiment of the invention comprises a storage cartridge 12, a first container 14 disposed over a cartridge 12, a coiled spring 16 disposed over container 14, a second container 18 disposed over spring 16 and first container 14, and a nose portion 20 connected to the front end of container 18, the elements assembled as in Fig. 1. The device 10, dimensioned to be manipulated with one hand only, is preferably formed of clean, transparent plastics material so that observation may be made through nose portion 20 during application. The front end 80 of catheter 22 may be inserted manually or by means of the applicator itself into the urethra and the operator, gripping the device at the base 30 and rim 62 between thumb and forefingers, Fig. 7 (not shown), moves containers 14, 18 towards each other against the action of spring 16. The pressure is then eased to allow spring 16 to return to its uncompressed state. This reciprocating action has the effect of progressively drawing catheter 22 from its coiled position in portion (24), Fig. 2 (not shown), straightening and intermittently moving it forward and out of passageway 78 and into and through the patient's urethra. Flaps (54), (66) prevent the catheter 22 from retreating each time spring 16 is released from compression. Further embodiments include the use of a pair of resilient strips (86), Fig. 3, 4 (not shown), instead of a coiled spring 16, a flexible, transparent sleeve (110), Figs. 5, 6 (not shown), and a resilient spring member (124) connecting parts (126), (128), Figs. 8, 9 (not shown).

Title: Apparatus for starting electric synchronous motors
IPC: H02K19/12
Filed: 1920-09-11
Abstract: 151,269. Compagnie GÚnÚrale Electrique. Sept. 20, 1919, [Convention date]. Motors, controlling; exciting.-In the method of starting a synchronous motor by providing the rotor with a two-phase winding R connected through resistances RD which are gradually cut out until the rotor winding is short-circuited, after which the rotor winding is fed with continuous current, the source of continuous current is connected to the rotor winding through resistances RA before the short-circuit is broken. In the final position of the controller the resistances RA are cut out of circuit. Instead of connecting the two-phase windings to two separate sources of direct current, as shown, they may be connected to a single source. According to the Specification as open to in spection under Sect. 91 (3) (a) one of the sections of the two-phase winding may act as a compensating-winding, the other winding acting as the exciting-winding. This subject-matter does not appear in the Specification as accepted.
Patent GB-620304-A (GB)
Title: Improvements in automatic yarn-winding machinery
IPC: B65H54/10
Filed: 1945-10-08
Abstract: 620,304. Winding yarn. KIMPTON, W. H. Oct. 8, 1945, No. 26175. [Classes 120 (ii) and 120 (iii)] [Also in Group XIX] An automatic yarn winding machine comprising doffing and donning mechanism embodies a member adapted to be moved to initiate a cycle of said doffing and donning mechanism, and a counter and stop mechanism adapted to be operated step by step by the motion of said member, and after a predetermined number of such steps to act on said member so as to prevent further motions thereof. As shown, a counter and stop mechanism is applied to the automatic pirn-winding machines described in Specifications 534,337 and 619,499 in which, on the completion of a pirn, the stop-start handle 15 is moved upwards to the stop position, thereby moving lever 14 to allow spindle 12 to rotate and catch lever I to rise, releasing spring-loaded lever 6 which forces lever 5 inwards with its end 7 in engagement with a notch 4 in the edge of rotating driving disc 2. In this way, disc 2 drives disc 3 round for one revolution, thereby rotating cam shaft 1 to which disc 3 is keyed, and which brings about the various doffing and donning operations. The counter and stop mechanism is operated from a lever 18 fixed to spindle 12 and comprises a casing 19 secured to the machine frame, a numbered disc 22 on a central spindle 21 which also carries a radial lever 25 on which is mounted a pawl 26 adapted to engage a ratchet wheel 23 secured to a disc 22, the ratchet teeth being angularly disposed opposite the numbers on the edge of the disc and being at least equal in number to the greatest number of pirns to be wound. A stop pawl 27 is pivoted to the body of casing 19, and the movement of lever 25 is limited by a.stop 28. Perforations 30 are provided in disc 22 close to the numbers, a stud 31 being inserted into the perforation corresponding to the number of pirns to be wound. At each doffing and donning operation, lever 18 is oscillated, causing lever 25 to fall and rise so as to advance ratchet wheel 23 by one tooth against the action of a spring. The number of pirns which have been wound is shown in window 24. After the pre-determined number of doffing and donning operations. stud 31 is driven into engagement with lever 18 and prevents it from moving. On the next movement of start-stop lever 15, spindle 12 is held against rotation and the doffing and donning mechanism is prevented from operating, the machine remaining idle. To reset the counting device, button 35 is pressed, releasing stop pawl 27 so that ratchet wheel 23 and disc 22 rotate backwards under the action of the spring, carrying with them lever 25 and pawl 26 until the pawl tail 29 engages stop 28 and releases the pawl from the ratchet wheel which then rotates to zero position unimpeded by either pawl. Spindle 21 may be connected through a free-wheel device to a counter adapted to indicate the total number of pirns wound on the machine. Specification 486,304 also is referred to.
Patent GB-1417465-A (GB)
Title: Labelling machine
IPC: B65C9/46
Filed: 1973-06-01
Abstract: 1417465 Labelling machine PRICEMASTER Ltd 24 April 1974 [1 June 1973] 26187/73 Heading B8F A labelling machine comprises a structure 10 supporting an off-winding supply reel 11 for supporting strip 12 carrying a series of pressuresensitive adhesive labels, an on-winding collector reel 13 having means for imparting intermittent drive motion in the on-winding sense, a guide 33 for engaging the back of the strip, a label applicator 42 adjacent to the guide, a strip path being defined between the guide and the reels which path curves on the guide in an arc of small radius to allow peeling of the labels off of the strip, a printing head 15 and a platen 20 between the supply reel and guide for receiving the strip therebetween, means 34 for co-ordinating relative movement of the printing head and platen and the on-winding reel drive in a cycle of operation of the machine so that the strip is halted whilst the printing head and platen cooperate to print a label, and means for adjusting the position on the labels at which print is applied. Adjustment of the printing position on the labels is effected by an adjustable pawl 56 and a surface in the path of the strip between the supply reel and guide. The on-winding reel 13 has a built in unidirectional clutch system. In operation, an arm 17 is swung forward upon contact with the leading edge 76 of an article and an applicator arm 16 is also swung forward temporarily to avoid contact with the edge. Forward swing of the arm 17 rocks a frame 34 causing displacement of sleeves 39, 39<SP>1</SP> and a corresponding lengthening of the strip path. A pin 37 is carried upwardly and raises links 31 so that movement of a pin 29 in a slot 30 causes the printing head to swing about a pin 24. The printing bands 28 of the head are presented to an inking roller 22. The slots 30 allow overswing of the printing head to ensure inking of the bands over a range of adjustment of the pawl 56 to suit a range of label pitch lengths. Leaf springs 62 rise and thereby cause the pawl to rock about a pin 61 and engage its nose 57 slidably on the strip 12 on the platen 20. During its forward swing arm 17 rotates a lug 19 clockwise via a rod 18 with no rotation of the reel 13 occurring. The action of frame 34 of lengthening the strip path draws a fresh length of strip 12 from the supply reel 11 under the pawl 56, printing head 15 and guide 33 until spragged and halted by engagement of the nose 57 with the leading edge of the next label. At this juncture, a fresh label is ready for printing and a printed label has been peeled from the strip. The longer the effective length of the pawl 56 the sooner does its nose 57 sprag the strip when the pawl is rocked towards it and consequently, the more remote is the printing applied on the fresh label from its leading edge. The strip length which the frame 34 can potentially draw in each cycle can be modified by changing the position of roller 52 in slot 54. Also, the strip may be led over the front sleeve 37 direct to the reel 13.

Patent GB-871909-A (GB)
Title: A method for the production of casein-containing products
IPC: A23C9/123
Filed: 1959-07-31
Abstract: In making spreads by the lactic acid fermentation of a casein- and lactose-containing solution, the fermentation is effected by thermobacteria, e.g. Lactobacillus (thermobacterium) bulgaricus, Lactobacillus (thermobacterium) acidophilus, Streptococcus thermophilus, at the optimal growth temperature, and is halted by cooling, e.g. to a temperature below 20 DEG  C., when the required pH has been attained.  The casein employed may be rennet casein, acid casein, or matured cheese.  The solution may contain a phosphate or a citrate, or may be made weakly alkaline by an alkali metal carbonate, lactate, or tartrate.  Butter may be incorporated in the casein-containing solution.  The casein-containing solution may be sterilized, e.g. by heating at 70-90 DEG  C. for 15-5 minutes, before the fermentation is undertaken.  The fermentation may be carried out in the packing for the product.  After fermentation, the product may be covered by fruit jam or jelly, e.g. an alginate jelly, to prevent access of air and prevent surface infection.  An example is concerned with fermenting a sterilized, homogenized mixture of milk curds, butter, skimmed milk, sodium tripolyphosphate and water with Lactobacillus (thermobacterium) bulgaricus at 40 DEG  C.

Title: Improvements in the production of oxygen-containing compounds by oxidation of hydrocarbons
IPC: C07B35/04
Filed: 1948-10-13
Abstract: Oxygen-containing compounds are produced by the partial oxidation of hydrocarbons with gaseous oxygen in two stages at elevated temperature and pressure, the first stage being effected in presence of an inert gaseous diluent, and the second being effected at a higher temperature by introducing oxygen substantially free from inert diluent into the product of the first stage.  The oxidation of propane, butane, and other aliphatic, cyclo-aliphatic or aromatic hydrocarbons to acetaldehyde, formaldehyde, propionaldehyde, acetone, acetic acid, and methyl, ethyl, and propyl alcohols is referred to. The first stage is preferably effected at about 600-900 DEG  F. with air, and the second at 900-1250 DEG  F. with additional oxygen. Pressures are preferably 75-200 p.s.i.  The product is preferably cooled to 300-500 DEG  F., tars and resin removed by scrubbing, further cooled to 100-200 DEG  F. and scrubbed, and watersoluble compounds, e.g. aldehydes, acids, and ketones removed by absorption in water.  The residue of hydrocarbons and inert gas may be treated with a solvent such as kerosene or mineral seal oil to absorb particularly aromatic and unsaturated hydrocarbons.  Diethylene glycol or the like may be added to remove water vapour.  The hydrocarbons removed may be stripped from the solvent and recycled or separately oxidized.  The residual gaseous hydrocarbons and nitrogen may be compressed, e.g. to 600-1200 pounds per square inch, cooled, and treated with a hydrocarbon solvent, the unabsorbed nitrogen being expanded to cool it and compress air which is cooled by means of the nitrogen so as to liquefy it, fractionated, and the oxygen supplied to the second stage of oxidation.
