Title: Multiposition selector valve
Inventor: ACKER RICHARD C
IPC: F16K11/074
Filed: 1982-04-19
Abstract: A multiposition selector valve of the rotary type includes a valve body having a single inlet port and a plurality of outlet ports. Fluid communication between the inlet port and any one of the outlet ports is provided via a check valve assembly 60 mounted on the valve body, and via a fluid-providing conduit connected at one end to the inlet port via the check valve. The other end of the conduit is movable in rotary fashion for fluidtight engagement with any one of a plurality of valve seat areas associated with the outlet ports. The valve seat areas are integral portions of a flat metal disk 17 that can be removed from the valve body to facilitate maintenance of the valve. A single handle 90 rotates the conduit through its various selected outlet positions and operates the check valve assembly to open and close the valve at selected outlet positions. A ball 110 is interposed between the handle 90 and a check valve operating pushrod 100. <IMAGE>

Patent GB-2100312-A (GB)
Title: Cistern regulator
IPC: E03D5/10
Filed: 1982-05-07
Abstract: A water saving device for controlling the frequency of urinal cistern flushes comprises a float 15 which actuates a micro-switch 17. As the water level in the cistern 1 falls during flushing, the microswitch 17 closes and activates an electronic control means 19; this causes a valve 21 to cut off the water supply to the cistern through the inlet pipe 11 and a twenty minute timer to be actuated. Twenty minutes later the valve 21 is opened by the control means 19 and the cistern fills at full water pressure and empties through the syphon and downpipe 9. The process is repeated throughout the day alternative timer circuit diagrams are disclosed, and include a light sensor so that the process is discontinued at night. <IMAGE>

Title: Automatic continuous flow method for the assay of creatinine
Inventor: BASSI DANIELE
IPC: C12Q1/50
Filed: 1982-06-24
Abstract: An automatic continuous flow method for the assay of creatinine in a biological fluid comprises enzymatic transformation of the creatinine with an insolubilised creatinine desimidase, to give ammonia and N-methylhydantoin followed by quantitative determination of the resulting ammonia. The enzyme is preferably immobilized on a nylon tube by a technique involving:     a) alkylation of the nylon with triethyloxonium tetrafluoroborate; b) introduction of a linear-spacer chain on the alkylated nylon by treatment with hexamethylenediamine or ethylenediamine; c) activation of the spaced-nylon with a two-functional reagent such as dimethylsuberimidate a and/or glutaraldehyde; and   d) attachment of the enzyme to the activated nylon.   The assay is carried out using a set of reagents comprising (1) a reagent to remove any endogenous ammonia from the sample, (2) a reagent to detect ammonia produced from the creatinine and (3) the immobilized enzyme.

Patent GB-2124966-A (GB)
Title: Process and equipment for winding a flattened extrusion blown tubular plastics foil ribbon into a coil
Inventor: HALTER HARTMUT
IPC: B29C48/28
Filed: 1982-07-29
Abstract: A flattened plastics foil ribbon (3), which is drawn from a blown foil extrusion unit at a prescribed constant drawing speed and is wound into a coil (4), is subjected before winding to a periodic angular displacement of a thickness error (10), which is effected by a displacement tool e.g. the extruder die (1), which rotates at a certain angular displacement velocity (w). To produce a coil 4 of truly cylindrical external form, the angular displacement velocity (w) is reduced as the plastics foil ribbon is wound, in proportion to the increase in the winding times for successive foil layers, thereby maintaining a constant displacement arc of the thickness error (10) for each of a long succession of foil layers. Equipment for carrying out this process incorporates a monitor (15) which emits a control signal based on the number of foil layers and/or the coil thickness, the rest of the control equipment being adapted so that the controller (14) for the displacement tool driving means (13) maintains a constant displacement arc. <IMAGE>

Title: Electrical bay security device
Inventor: BILLINGHAM RIDLEY
IPC: F16P3/00
Filed: 1982-12-14
Abstract: An electrical bay unit has a disconnect switch which is switched off automatically when the bay door is opened. Mechanics or testers will often wish to switch on the unit independently of the door, e.g. using tools. However, such defeat of the automatic disconnect can lead to catastrophe if attempts are made to replace the unit in the bay with the switch on, at connect. To avoid this, a switch operated interlock tongue 3 is moved via a pin 10 in a slot 11 with transverse clearance, to interlock with a recess in a rail 2. At interlock the unit can no longer slide in and out of the bay on the rail. The tongue is part of a plate 5 in which the slot is cut, and which slides vertically between locking and unlocking positions between pins 6, 7, 8 and 9 which have circumferential grooves to guide the horizontal edges of the plate. This interlock is governed only by the disconnect switch and is practically undefeatable, howsoever the skilled man may manipulate the switch. <IMAGE>
Patent GB-829714-A (GB)
Abstract: 829,714. Vibration dampers. UNIVERSAL CONTROLS Inc. Aug. 20, 1957, No. 26259/57. Class 108(3) [Also in Groups XIX and XXXVIII] In a coin-collecting and registering apparatus (see Group XIX) there is provided a device for damping the vibration of a lever 19 which oscillates about a pivot at its upper end. A rod 104 is fixed at one end to the foot of the lever and has a stop nut 105 at the other end. A weight or plurality of weights 106 is free to slide along the rod for a substantial distance e.g. # inch. The inertia of the freely sliding mass tends to nullify any tendency of the lever to rebound.

Inventor: READER MICHAEL WALTER
IPC: E05B13/10
Filed: 1984-02-17
Abstract: A cylinder lock with a deadlock action can be left in a locked or an unlocked condition with the key removed. A lock barrel 16 is located within an inner housing 12 and the inner housing is located within an outer housing 10. A bolt 26 has one (locked) end position in which it locks together the inner and outer housings and one (unlocked) end position in which the inner housing can rotate relative to the outer housing. The mechanism protected by the lock is operated by turning the inner housing. Turning the key in one direction in the lock moves the bolt one way, and turning the key in the other direction moves the bolt the other way. However returning the key to the centre for withdrawal does not move the bolt. <IMAGE>

Title: Method and apparatus for assessing particle deposits
Inventor: JONES DAVID BRIAN
IPC: G01N15/06
Filed: 1984-04-09
Abstract: Particle deposits on a substrate (11) are quantified by placing them in a magnetic or electric field and noting the change caused to the field by the deposit. The invention has particular utility to ferromagnetic wear particle deposits removed from a lubricant sample by the influence of a magnetic field. Substrate (11) and deposit to be assessed are placed on support (13) positioned above coil (4) of differentially balanced coil pair (4) (5) coupled to AC energised coil (2) wound on core (1). The particles of the deposit distort the flux through coil (4) giving rise to an output at 9 after amplification and filtering (6) (7a. . . 7b), (8). If the substrate (11) affects the field a substrate without a deposit is located below coil (5). <IMAGE>

Title: Flexible containers
Inventor: YAZAKI JINICHI
IPC: B65D35/08
Filed: 1984-05-25
Abstract: A squeeze package comprises a flexible plastic hollow vessel containing a viscous substance e.g. tomato paste, the hollow vessel comprising a flexible cylindrical barrel, a narrowed orifice passage 8 connected to the barrel through a shoulder 5 and a residence portion 10 connected to the orifice passage through a stepped portion 9 and having a squeeze opening 6 on the top end thereof. The substance has a viscosity of 1,000 to 250,000 cP, and the dimension of the vessel and the viscosity of the substance are within the range satisfying the requirements represented by the following formulae:  log  eta  >/= -log l -log S1/S0 + 5.45,  log  eta  >/= 0.588 log S0 + 0.764 log E + 2.30, and  S1/S0 ??? 2 wherein  eta  stands for the viscosity (cP) of the substance, S0 stands for the cross sectional area (mm<2>) of the orifice passage, S1 stands for the cross sectional area (mm<2>) of the residence portion,  l  stands for the length of the residence portion in the axial direction and E stands for the elastic recovery (g) of the cylindrical barrel in the non-packed state. The narrowed orifice passage helps prevent air from being sucked into the container as the container returns to its original shape when the pressing force is released. <IMAGE>
