Title: Improvements in or relating to electric steaming irons
IPC: D06F75/26
Filed: 1945-06-23
Abstract: 598,199. Electric steaming irons. KISTNER, M. M. June 23, 1945, No. 16073. Convention date, June 5, 1940. [Class 138 (ii)] A steam-electric iron comprises an ironing plate, a heating means united therewith and projecting above the surface of the plate or means secured to the plate providing steam flow passages. The base of the iron is formed of an aluminium die casting and is divided by a transverse wall 29 into a nose portion and heel portion. Cast integrally therein' is a heating element 36, Fig. 8, surrounded by an insulating sheath 37 and a metal sheath 38. The element extends to the nose of the iron from terminals 72 at the heel as shown by dotted lines 40, 41 in Fig. 4. A steamgenerating zone 43, 48 is cast in the base, the contours of which generally conform with the shape of the element, the wall of metal surrounding the latter being thin to allow rapid heat transference. Steam generated by the iron communicates with the atmosphere through channels 57, 55, 63, 64, chambers 58, 59 and small bores 62. The channels are completed by a sealing plate 31. The heating element is controlled by a thermostat 74 adjustable by a pointer 78. A water reservoir is provided in the body 21 of the iron which comprises a metal shell 79, the bottom 82 of which is spaced from the base of the iron to reduce conduction of heat therefrom. The body is connected to the heel of the iron base by screws 93 and to the front end by a ring 98 secured to a nipple 94 by a valve member 100, the nipple being screwed into the base. The iron handle 104 is secured to the reservoir by screws 107 at the rear and a bush 110 and nut 111 at the front. A valve 103, operable by a thumb-ring 122 in the handle 104 adjusts a needle 102 relatively to a port 101, the valve member 100 thus regulating the rate of flow of water to the steam generating zone 43. The reservoir is filled by pouring water through a passage 124 in the valve stem 103, air from the reservoir escaping through an outlet 129. such outlet limiting the level of water in the reservoir. When up-ended the iron rests on its heel 90 and a rib 132, in which position the water level falls beneath the valve 100, and a ball 127 within the valve stem prevents the escape of the water by seating against a shoulder 128. When used as a dry iron, the valve is closed and when used as a steam iron the thumb-ring 122 is set in correspondence with the setting of the thermostat pointer 78, Fig. 2.

Title: Improvements in or relating to the production of moisture-proof sheet wrapping material
Inventor: BERRY WILLIAM
IPC: C08J7/048
Filed: 1949-06-16
Abstract: 670,108. Moisture-proof sheet wrapping material. BRITISH CELLOPHANE, Ltd. June 12, 1950 [June 16, 1949], No. 16108/49. Class 140. Moisture-proof sheet wrapping material is produced by a process of.the kind in which a partially condensed urea-formaldehyde resin is applied to a base film of water-sensitive, non- fibrous organic material from an aqueous dispersion containing substantially no condensing agent, the resin film is dried and a moistureproof coating is produced by applying a composition containing a film-forming agent and a volatile organic solvent containing a dissolved acid condensing agent for the resin, and the solvent is then evaporated. According to the invention, the condensing agent is a material which yields sulphur dioxide, e.g. sulphur dioxide itself, sodium sulphite or hydrosulphite which evolve sulphur dioxide in the presence of traces of acetic acid, &c. The sulphur dioxide may be added as a liquid or gas to the coating composition to provide a pH of 4 or less. As the base film, there may be used regenerated cellulose from viscose, cuprammonium cellulose, &c., alginic acid derivatives, gelatin, casein, lowly substituted cellulose ethers or esters, polyvinyl alcohol, &c. As the moisture proofing coating, there may be used solutions of nitrocellulose, ethyl cellulose, cyclized rubber, copolymers of vinyl chloride and acetate, &c, The term "urea-formaldehyde resin " includes thiourea formaldehyde resin and (thio)urea-formaldehyde/aliphatic alcohol resin.

Title: An improved integrating circuit
Inventor: RASMUSSEN JENS
IPC: G06G7/186
Filed: 1961-05-04
Abstract: 981,149. Integrating circuits. ATOMENERGIKOMMISSIONEN. May 4, 1961 [May 5, 1960], No. 16123/61. Heading G4G. An integrating circuit comprises a D.C. amplifier, a main capacitor connected between the input and output of the amplifier and an auxiliary capacitor arranged so that it may be connected alternatively either between the input of the amplifier and a point on a voltage divider connected between the output of the amplifier and earth or as a member of a circuit designed to change the charge of the auxiliary capacitor, so that the voltage output of the amplifier may be scaled by a given factor. One circuit embodiment (Fig. 3) may be used for either up or down scaling, and allows the auxiliary capacitor to be charged from the initial potential across the amplifier itself. During the initital operation of the integrating circuit the auxiliary capacitor C 2  is connected as shown in Fig. 3, so that it is charged to a voltage e u . For upscaling, the switch 4 is opened, and the switch 10 is adjusted to connect the capacitor C 2  to the point 9. Then, since total charge remains constant Cu (C 1  + C 2 ) = ae u  C 1  + kae u  C 2  where k = R 2 /R 1 +R 2  and a is the scaling factor. Thus a = C 1 /C 2  + 1 / C 1 /C 2 +K, representing an upscaling since k < 1. When the operation is finished the switches 10 and 11 are changed so that C 2  is connected to earth (through the resistor R 3 ) and to the output point 3 so that the capacitors become charged to a value in accordance with the output voltage of the amplifier after rescaling, i.e. aE. If the capacitor C 2  is finally connected across the amplifier 1 again and the switch 4 is closed, the operation of the integrating circuit can continue. (The switch 4 could be kept closed throughout the operation, but with loss of accuracy). Downscaling may be produced by altering the switching sequence. The switches may be automatically operated by using circuits designed to operate appropriate relays when the output voltage from the integrator reaches a limit value. A more simple circuit suitable only for upscaling is also described, using a battery for charging the ausiliary capacitor (Fig. 2 not shown).

Filed: 1921-06-13
Abstract: 185,529. Sabulite (Great Britain), Ltd., Bellingham, J., and McCandlish, W. H. June 13, 1921. Presses, delivery.-In a machine for moulding concrete. blocks &c. in which the pressure is applied by an hydraulic ram to material contained in a downwardly discharging mould-box invertible for filling, the pressure is transmitted by the ram lifting a movable press head associated with the mould into contact with a fixed portion of the machine. After charging, the mould 2, which is of the type described in Specification 181,754, is inverted, along with the head 11, on trunnions 3, by means of a wheel 6, and is then raised by the ram 22 until the ends 11<1> of the head 11 contact with the fixed projections 1<1> in the frame 1. The head 11 is connected to the mould by bolts 9 having limited movement, so that further advance of the ram causes a plate 13 slidable in the mould to contact with the head 11 by means of upwardly extending legs 15, and thus compress the material. The plate 13 is shaped according to the required contour of the block, and is supported by springs 14 against pins 14<1> adjustable to regulate the thickness of the block. The legs 15 have enlarged ends and slide in the plate 13, so that the upper portion of the material is compressed first and then the lower portion. Between the ram and the mould are mounted a stool 18 to allow restriction of the ram's stroke, and a tray 16 to receive and deliver the moulded article. The stool 18 is mounted on wheels 19, and is moved into and out of position by links 46, 47, 49 operated by a wheel 45. The tray 16 rests by means of projections 17 on brackets 25 carried by cross-heads 26, and is reciprocated in guide-rods 27 by levers 31, 32, 35, 35<1>, 36, 36<1>, actuated by a wheel 28.
