Patent GB-2031457-A (GB)
Title: Staining and analysis of bacteria
IPC: C12Q1/04
Filed: 1979-09-11
Abstract: A bacterial staining composition for both gram-negative and gram- positive bacteria comprises a chelating agent and a basic dye, both of which are operative at a pH above 7.0. Staining is effected by contacting concentrated or fluidly suspended bacteria with the composition at a neutral or basic pH. Bacteria thus stained and concentrated by filtration, or centrifugation are readily visible. The gradations of color of the stained, concentrated bacteria correspond to the number of bacteria and semi-quantitative analysis may be effected by comparison with a standard. Differentiation of gram-negative and gram- positive bacteria is accomplished by treating the stained bacteria with an organic acid wash at pH 2.5-2.6. which decolorizes only stained gram-positive bacteria. A method for determining bacterial susceptibility to antimicrobial agents comprises incubating bacteria with an antimicrobial agent, staining, and thereafter comparing the color gradation of the stained, concentrated bacteria with a control or standard.

Title: Improvements in or relating to a mechanical drive mechanism for rotary cultivators
IPC: F16H37/08
Filed: 1980-03-27
Abstract: A variable ratio transmission utilises a double expanding VEE-belt pulley 15a 15b, 16 the shaft 14 of which is driven in use to transmit drive to two respective VEE-belts 17a, 17b. Each belt in turn drives one input 19a, 19b of a corresponding differential 11a, 11b, so that the rates of rotation of the output shafts (not shown) of these latter will depend upon, inter alia, the adjustment of the common member 16 of the double VEE-belt pulley. The other inputs 10a, 10b of the differentials are driven by belts 8a, 8b from a shaft 6 which also drive the shaft 14 through gearing 12, 13 and itself driven by a prime mover 1 through a belt 4. Reversal of relative rotation of the two output shafts may be achieved. The transmission is illustrated in use in a rotary cultivator. <IMAGE>
Patent GB-2052889-A (GB)
Title: Terminal block
IPC: H01R9/24
Filed: 1980-05-15
Abstract: Some terminal blocks, e.g. as used in telephone switching installations use wire guides with channels to guide the wires to the contacts to which they are to be connected. Hitherto these wires were introduced from the sides of the block and emerged at the front or rear sides, but this made the introduction of new conductors difficult when numerous cables and jumpers were present. The terminal block described herein has a stack of flat terminal strips (7) interleaved with the wire guides (8), thereby extending between the front and back plates (3-3') of the block. The wire guides each have channels for the wires each of which is preferably crescent- shaped with both ends (e.g. 5) at the same edge of the wire guide. The wires come in from the front or back, via fingers (24) which together define a cable comb, and each such wire is pushed into one of the channels from which it emerges near the terminal (e.g. 26) to which it is to be connected. The wire is then connected to the terminal, e.g. by insulation displacement. <IMAGE>

Patent GB-2053432-A (GB)
Title: Incinerator device
IPC: F23G5/46
Filed: 1978-09-21
Abstract: Oven exhaust gases containing combustible solvent vapours are introduced (e.g. via a duct 20) into a housing 21 for the incineration therein (to oxidise said vapours) in a U-tube 30 supported in the housing (e.g. on legs 38) and having an inlet end 33, Fig. 2, opening into the housing to receive the gases from the housing, a burner, e.g. 46, being mounted in said inlet end to incinerate the gases before their discharge from the outlet end of said tube (e.g. to a heat exchanger 40). The oven gases within the housing and surrounding the incinerator tube effectively provide thermal insulation and so avoid the need for the use of absorbent insulation material within and around the incinerator tube. A negative oven pressure created within the housing and duct (e.g. by a suction fan 16 withdrawing the gases from the oven to and through the incinerator device) reduces the risk of fire in the event that the incinerator flame is temporarily extinguished, and reduces leaks. <IMAGE>

Title: Continuous towel cabinet
IPC: A47K10/28
Filed: 1981-03-27
Abstract: A continuous towel cabinet 10 has an arrangement of rollers 14, 15, 16, 19 for allowing clean towel to be withdrawn and for soiled towel to be rerolled, and a device for metering the length of clean towel which may be withdrawn at any one time. The metering device operates on a cycle defined by two revolutions of one of the rollers 14 during which a pin eccentrically mounted on one end of said one roller engages during the first revolution a first flange 28 on a plate 25 mounted for vertical movement to lift the plate from a lowered release position into an intermediate position where it is held by interengagement of holding means on said one roller and the plate, then engages during the second revolution a second flange 29 on the plate to lift the plate into a raised stop position in which it is held for a fixed period of time by engagement of a sucker 30 carried by the plate with a fixed sucker 31, and finally engages a stop 43 on the plate which precludes further rotation of said one roller and thereby further withdrawal of clean towel until the suckers disengage allowing the plate to fall to its release position. The holding means which prevents the plate 25 for falling from its intermediate position after the pin 38 has disengaged from flange 28 and before it has engaged lower flange 29 comprises a projection 39 on the plate which slides over a peripheral ramp on the rotating roller while the plate is in the intermediate position but can pass through slot between the ends of the ramp during vertical movement of the plate. <IMAGE>
