Title: Alarm systems
Inventor: SACKS MICHAEL
IPC: G08B13/12
Filed: 1981-10-24
Abstract: An alarm system is used to give warning of unauthorised penetration of a surface such as a window or wall or other structural surface. A layer of conductive material (1, 2) is applied to the surface and its conductivity or other electrical property is monitored with an electrical circuit (6). A change in the monitored property due to penetration of the surface and consequent disruption of the conductive material is detected by the electrical circuit and an alarm indicator (8) is operated. The conductive material may comprise a metal mesh or conductive foil or other material and may be applied over the surface to be protected or alternatively incorporated within same. <IMAGE>

Title: Hydrostatic transmission for driving conveyor of wet ash removal apparatus
Inventor: BUCHMULLER HORST
IPC: B65G43/08
Filed: 1982-10-28
Abstract: Wet ash removal apparatus comprises an endless conveyor having drive input means (5) driven by an electric drive motor (6) through an hydrostatic regulating gear (7), the conveyor being arranged to circulate in a trough (1) of the apparatus. The hydrostatic regulating gear (7) is provided with a pressure monitor (14), which acts on a setting drive (16, 17). A setting lever (17) of the setting drive is connected with a gear shift lever (13) at the hydrostatic regulating gear (7). On a change in the pressure of oil in the regulating gear, a change in the output rotational speed of the regulating gear is effected automatically through the setting drive. Thus, an increase in the quantity of ash causes increased oil pressure resulting in an adjustment of the displacement of the pump of the hydrostatic gear (7) so as to increase the speed of the conveyor. <IMAGE>

Title: Motion compensators and mooring devices
Inventor: BREWERTON ROBERT WALTER
IPC: B63B35/44
Filed: 1984-12-19
Abstract: A compensator for providing resilience in a connection between relatively moveable objects comprises a piston (3) working in a cylinder (2) which is surrounded by a larger coaxial cylinder (1) joined thereto by annular wall members (1a) thus defining about the cylinder (2) a pair of annular reservoirs (8, 9,) The piston (3) divides the cylinder (2) into a pair of chambers (6, 7), chamber (6) being connected by conduit (12) to reservoir (9) and chamber (7) being connected by conduit (10) to reservoir (8). Each reservoir contains a mixture of liquid and gas whilst the chambers contain liquid. Elongation of the connection between the objects causes withdrawal of the piston (3) with consequent expansion of the volume of gas in reservoir (9) against atmospheric pressure and against pressure developed in reservoir (8) as a consequence of decrease of gas volume therein.

Title: Commodity meters
Inventor: JEFFERS RICHARD
IPC: G01D5/25
Filed: 1984-12-19
Abstract: A gas or other commodity meter has a mechanical counter mechanism comprising a plurality of rotating indicators which can be read visually. In order to allow the reading to be read at a distant location or by a computer an electrical coded representation of the reading is set up. Associated with each rotating indicator is a rotating slider, which slides on a stationary printed circuit board (11, Figure 5) having on its face a pattern of four concentric rings of spaced contact strips, arranged in the Gray code. As the slider passes over the strips it energises them in a pattern unique to the decimal digit shown by the rotating indicator. Multicore cable (21) is connected to each of the strips and leads to a reading device at which the pattern of energisation is decoded. Figure 3 shows an alternative pattern of contact strips. <IMAGE>

Title: Screw rotor machines
Inventor: HOUGH DAVID
IPC: F04C18/16
Filed: 1985-05-28
Abstract: A screw rotor machine for compressing air or other working fluid comprises a housing (11) including two intersecting bores axes which together define a working space (14). The pair of intermeshing rotors (22, 23) are rotatably mounted one in each bore. The rotors have helical lands and intervening grooves whereby rotation of the rotors in connecting engagement is effective to compress the working fluid (or to expand the fluid if the machine is used as an expander). A low pressure port (16) and a high pressure port (19) formed in the housing at opposite ends thereof permits inlet and outlet of the working fluid. The grooves (28, 34) of the rotors each have a primary flank (31, 37) and a secondary flank (32, 38). The tips of the primary flanks of both the male and female rotors are formed by parabolic arcs which generate major portions of one of the flanks of the opposite rotors. A major portion of the secondary flank of the female rotor is also a parabolic arc.

Title: Water treatment by means of a cloud of flocs
Inventor: VOSTRCIL JOSEF
IPC: C02F1/52
Filed: 1985-06-06
Abstract: A method for flocculating and separating in a cloud of flocs, during which flocs are enlarged and thickened by a common effect of hydrodynamic and physical-chemical forces in a concentrated suspension at a non-turbulent flow in water cylinders. Water cylinders rotate between a sinusoidally rising vertical flow of water and walls. The average rate gradient is constant or decreases in the direction of flow. The clarifying effect is achieved by adding an auxiliary coagulant and by a periodically repeated change of hydrodynamic forces in the liquid. The space of the cloud of flocs is divided into partial sections by means of a system of vertical submersible walls, which are undulated sinusoidally or with sharp edges, or are flat and provided with deflectors. The upper edge of the walls projects above the overflow edge for sludge. Geometrical shapes of walls and their surfaces, as well as dimensions of defectors are dependent on the width of the partial section. <IMAGE>

Title: Variable proportioner
Inventor: MUELLER THOMAS D
IPC: F04B13/00
Filed: 1985-09-12
Abstract: Fluid pressure drives piston 40, which itself drives slave pump piston 68 via a pin-and-slot connection 156, 154 between the piston rods 20, 152. Spring 150 biases piston 152, 68 to the position where it is fully engaged in its cylinder and the pin-and- slot connection may be adjusted by captive nut 142 to alter the stroke of piston 68 and hence its delivery. Arm 96 carried by piston rod 20 moves reversing rod 100 and hence toggle 106 which is spring biased into its end positions and which moves valve member 64 so that piston 40 is reciprocated by means of altering the direction of supply of driving fluid. The output of the slave pump is fed into the main fluid flow and a pivotable connection 111, 112 is provided for the toggle-lever spring to enhance the life of the spring by reducing its bending. <IMAGE>

Title: Combination labelling and literature applying machine
Inventor: VOLTMER HELMUT
IPC: B65C9/18
Filed: 1986-08-13
Abstract: A system for applying labels 2 and literature packets 35 to containers 7 includes a rotary drum 202, Figure 1 which is heated for activation of adhesive coatings provided on bands 18 to secure the packets 35 and labels 2. The drum is provided with mouthpieces 4 employing suction for holding literature packets 35, support bands 18, and labels 2. Dispensers are mounted peripherally around the drum at successive work stations 1, 17, 48 for transference of labels 2, bands 18, and literature packets 35 to the mouthpieces as the drum rotates. At a final work station, a conveyor 201 transports the containers 7 to the drum whereupon the bands and labels are secured to the containers during rotation of the containers between the drum and pressure pads 59 which engage the adhesive coatings to the outer surfaces of the containers. A photoelectric sensor 301 responds to the presence of a container 7 on the conveyor 201 and triggers a mechanism 302 to dispense a label 2. The presence of a label 2 on the drum closes a first vacuum actuated electric switch 206, Figure 6, to transmit a signal to a solenoid 31 to dispense a band 18. The presence of a band 18 on the drum closes a second vacuum actuated electric switch 210 to transmit a signal to a transfer roller 50 to dispense a literature packet 35. <IMAGE>
