Title: Improvements in or relating to the cultivation and sterilization of bacteria and the like
Inventor: WRIGHT ERNEST CHARLES
IPC: C12M1/00
Filed: 1958-06-05
Abstract: 926,541. Incubators. MINISTER OF AGRICULTURE, FISHERIES & FOOD. Sept. 4, 1959 [June 5, 1958], No. 17985/58. Class 5(2). An incubator for cultivating bacteria, moulds or tissue comprises a container which may either be maintained fluid-tight or may be provided with a controlled, constant or intermittent supply and exhaust of air, the container comprising an observation panel and a door in the wall thereof, and having an air circulating system, heating means controlling the temperature of the circulating air, a culture flask carrier, and means external to the container for moving the carrier to bring the flasks into register with the observation panel. The incubator comprises a casing 13 of polished aluminium and fibre glass mounted on an annular base 1 of concrete covered with a layer 2 of asphalt and a layer 3 of waterproof cement, and provided with an observation door 19 of transparent material such as armoured glass. Bacteria can thus be inspected whilst being cultivated and sterilized within the incubator, without the risk of infection being incurred. The casing contains a circular rack 21 for culture flasks 22, mounted on a rail 23 fixed to the base 1 of the incubator. In order to bring the various culture flasks into register with the transparent door 19, the rack is rotated on the rail 23 by means of a motor 24 mounted on the top of the incubator and driving a sprocket wheel 27 which in turn drives a chain 28 fixed to the rack. The bacteria within the culture flasks 22 are cultivated by circulating a current of warm air round the incubator by means of a fan heater unit 36, 37 detachably mounted within a duct 32 suspended from the top of the incubator, and controlled by thermostats 45 coupled to a control panel 46. The culture is sterilized by feeding water into the well formed within the annular base 1, and boiling the water by circulating steam round the coils of a steam pipe 12, the steam so generated being circulated round the incubator with the air. By operating the wheel 11, the plug 8 is then raised from the outlet 4 of the well, and the water is thereby drained off, and in order to cool the incubator after the sterilization process, a strong current of cold air is passed through it via the inlet and outlet pipes 40, 41, these pipes being provided with valves 42. Bleed pipe lines 43 and 44, fitted with valves for controlling the rate of flow of air therethrough, provide a means of gradually changing the air within the incubator without causing variations in the temperature. Control culture flasks may be housed in a stationary rack 47, and then observation facilitated by one or more fluorescent light tubes 48.

Abstract: 515,595. Making cartons. BISHOP, E. L. June 17, 1938, No. 17998. [Class 18] A carton blank formed with end wall a' and tabs a<1>, a<2> passes, in its passage through a carton making machine, deflectors e which bend these walls and tabs upwards, the tabs subsequently falling back into an horizontal position due to their inherent resilience while the walls a' are kept upright by a support h, or two supports f, h. While in this condition the blank passes gumming rollers which apply adhesive to the tabs only. The leading face of support f, and the leading edge of support h are oblique so that the tabs are forced to the horizontal position and pass underneath them. In a modification, a bar which is adjustable in height connects the deflector e and support f and is employed where the length of the tabs is comparable with that of the wall, but the height is less. The blanks slide on rails b and are moved by projections c' on chains running in the rails, and they are pressed down by belts d. The deflector and the supports, the latter being adjustable, are duplicated on the opposite side of the machine. Specification 515,596 is referred to.

IPC: A43D49/00
Filed: 1938-06-25
Abstract: 516,471. Welt - beating machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). June 25, 1938, No. 18863. [Class 17 (i)] A welt-beating machine has a work rest and work feeding jaws arranged for swinging movement to feed the work past the hammer. A presser foot holds the welt when it is not being fed. A slashing knife is brought into operation at the will of the operator, the feed of the welt being interrupted while the knife is making a slash. The hammer moves widthwise of the welt, to smooth the inseam. The work rest 12 has a thin lip 24 to enter the welt crease. The hammer 14 is carried by a lever 48 pivoted at 56 and oscillated by a cranked portion of a shaft 64. The hammer can yield against a spring 39, and is pivoted at 52 to the lever 48, the lower end of the hammer being connected by a link 82 to a bell crank lever 78, 74 actuated by a link 68 reciprocated by the cranked portion of the shaft 64. When not being fed the welt is clamped to the support 12 by a foot 16 secured to a lever pivoted at 88 and carrying at its other end a slide block 92 oscillated by a fork 94 urged in a direction to clamp the work during a large part of the machine's cycle by a spring, and cam actuated to free the work when this is to be fed. For feeding the work a claw 20 co-operates with a rest 18 sliding on the support 12, both claw and rest being mounted on a bracket 142 pivoted at 144 and swung from side to side by connections, including a link 190, from the lever 48. On the feeding movement the claw is depressed by a lever 174 driven from the arm 74 by connections including a latch 250 urged to operative position by a spring 256. The knife 22 is carried by a knife 276 reciprocated by a link 324 and lever 284 oscillated by a cam 294. This cam is set in motion when a treadle is depressed, a treadle rod 316 swinging a lever 312 to release a clutch bolt 306 co-operating with a groove 308 in the main worm-wheel, the starting piece 310 withdrawing the bolt after one revolution if the treadle has been released. The knife is caused to make five small successive forward movements during one rotation of the cam, after which the knife is withdrawn from the slash so made by a single movement. The hammer, also, strikes five blows during one rotation of the worm-wheel. The feed of the work is interrupted while the knife is making a slash, the lever 324 being resiliently connected to a lever 340 having a hooked portion 342 arranged when swung clockwise to hold the lever 174 up at its forward end. The cam 294 is formed with a dwell so that three steps occur before the lever 174 is held. Therefore, if the treadle is held down, a slash alternates with three steps of work feed.
