Title: Wire attachment element for corrugated cardboard cartons - has corkscrew form with bevelled end and insertion tool with chuck to match
IPC: F16B25/00
Filed: 1975-01-30
Abstract: Firm joints in corrugated cardboard cartons are possible with this form of wire screw. The wire (1) is made in the form of a corkscrew with one end (4) bevelled to aid penetration and the other formed into a ring head (2) with a radial portion (6). The radial portion and ring head are so formed to match an insertion tool chuck. Radial slots in the chuck accept and apply torque to the radial part (6) of the wire and an annular rebate centres the wire in the chuck. The chuck itself is driven axially within a cylinder by a coarse thread screw connected via balls to an air driven ram and made to rotate by the fixed nut.

Title: Electronic ignition circuit for IC engine - varies output of magnetic generator to reduce power consumption at lower engine speeds
IPC: F02P3/045
Filed: 1975-03-27
Abstract: The electronic ignition circuit is used for an internal combustion engine. It simplifies the alteration of dwell time (= closed/open time) by varying the output of the magnetic generator. This variation is a function of the speed of the engine and it is such that the power consumption of the ignition circuit is less at lower speeds. The generator has its output varied by a diode and capacitor circuit, and this diode and capacitor circuit is connected to the armature winding of the generator and produces a dc voltage proportional to the peaks of the generator's output. This dc voltage modified the output and thereby alters the percentage dwell.

Title: Precast alveolar paving slab for car parks - is rammed into loose ground obtaining contiguous paved area with edge tied by inclined pins
Inventor: COIN ANDRE
IPC: E01C9/00
Filed: 1976-05-19
Abstract: The precast pacing slabs may be used on hard shoulders or car parks. They may be of reinforced concrete with regularly distributed through drainage holes, and are tied together once installed. The tying system may deploy inclined removable pins (5) which unite the edges of two abutting slabs (1).

Title: Removal of sulphur oxide cpds. from waste gases - by contact with soda slag from metal desulphurisation
Inventor: JECKO GERARD
IPC: B01D53/50
Filed: 1976-06-25
Abstract: Desulphurisation of waste gases contg. S oxides (esp. SO2) is carried out using a desulphurising agent comprising the soda slag formed during the desulphurisation of metal melts with Na2CO3 (e.g. in a blast furnace). Process for combatting water pollution by Na salts of sulphur oxyacids (esp. the Na2SO4 formed above) comprises adding the Na salts to an aq. Fe2(SO4)3 soln. at 50-90 degrees C, thereby forming an insoluble ppte. The two processes A and B can be integrated to combat air pollution by SO2-contg. waste gases (e.g. from iron ore briquetting units), water pollution by the Na2SO4 formed with the first, and also water pollution by FeSO4 formed by picking rolled steel sheets with H2SO4, since the FeSO4 can be oxidised to Fe2(SO4)3 for use in the second process.

Title: Conjugates of penicillin and gamma-globulins - useful for suppressing penicillin allergy
IPC: C08H1/00
Filed: 1976-08-31
Abstract: New non-immunogenic conjugates (I), suitable for suppressing the formation of reaginic antibodies in a host are described. They consist of the hosts own gamma-globulin (II) to which are attached, 4.3-19 (pref. 9-12) benzylpenicilloyl (BPO)gps.

Title: Flocculating and draining sludge from effluent purificn. plant - in low cost low energy potentially mobile filter plant
IPC: C02F11/123
Filed: 1976-09-03
Abstract: Thesludge is received into a primary flocculating, rotary drum inside, a coaxial contra-rotating filter drum. The flocculating drum delivers into a pre-dehydrating, rotary drum from which sludge is spread via a distributor onto an endless first filter band. The loaded, first filter band is lapped around the filter drum under pressure of an outer, driving filter band. This first pair of filter bands delivers to successive filter bands, zig-zag lapped between pressure rollers to achieve adequate drainage. The flocculating drum pref. has central, coaxial inlet and outlet and is supplied with a mixt. of sludge and flocculating agent. Filtrate passing into the filter drum via perforations in its circumference is pref. discharged to the sides of the drum by deflectors. Paddles are pref. provided on the exterior of the flocculating drum to assist lateral discharge of filtrate. Used for dehydrating sludge discharged from waste water purificn. processes. The installation is inexpensive to install and simple and cheap to run, requiring negligible maintenance. It produces a dehydrated prod. of desirable homogeneity, density etc. It eliminates a supplementary flocculation station. The design lends itself to a packaged, mobile construction which could be used at several sites.

The installation is capable of handling much larger quantities of fluid than known machines. From the mixt. fed in under pressure, the liq. can be drained off below whilst gas, free from liq. is delivered at the upper end.

Title: Non-return valve for pipeline - has metal flap disc enclosed in rubber which forms spring loaded hinge and also seals on valve seat
IPC: F16K15/14
Filed: 1976-10-26
Abstract: A non-return valve (1) consists of a metal disc (2) with a central hole (4) clamped between the flanges of a pipe line. The valve flap (6) is a metal disc enclosed in rubber and joined by a flexible neck (7) to a surrounding ring (5) also of rubber. The valve flap (6) is normally held open by the pressure difference due to the flow of fluid (F). When the flow ceases or tries to change direction the resilience of the rubber neck (7) pulls the flap (6) onto the seat (8). The rubber coating of the valve flap forms an effective seal on the valve seat and at the same time protects the metal part of the flap against corrosion.

Title: Water thermal pollution prevention system - has cooled air circulated through tubes arranged in bundle perpendicular to water sheet falling in gallery
IPC: F28D7/16
Filed: 1976-12-08
Abstract: The system prevents thermal pollution by water used for cooling in factories and particularly thermal power stations. The water is brought into contact with cooling elements, typically tubes through which cold air circulates, and assembled in a bundle at right angles to the sheet of water falling through a gallery. The gallery can be divided vertically for its whole length into three distinct contiguous sections, the central one being used for the water flow. One outer section forms the air intake chamber, via filters, into tubes, and the other mixes the air originating from different levels.

Title: Mechanical element position sensing system - operates using switches enclosed in single hermetically sealed replaceable assembly
IPC: H01H13/18
Filed: 1977-03-23
Abstract: The position of a mechanical element is sensed by a number of switching elements enclosed in a single casing with any necessary telescopic mechanism. This avoids using numbers of hermetically sealed switches thus simplifying maintenance. A hermetically sealed detector comprises a cylindrical tube (1) with a deformable membrane (2) on one end and is soldered (3) to a base (4) in which there is a sealed connector (5). The base supports switches (7) retained by pins (8) and with their press buttons not aligned. The switches are wired to the connector. A disc (12) with telescopic system attached floats between the membrane and a compression spring (13) to contact all switches. A lever (15) welded to the tube prevents membrane fatigue by external operating system.

Title: Correction of errors in calorimeter - employs thermometer probe output to correct flowmeter output as function of density (SW 6.2.78)
Inventor: METZGER MANFRED
IPC: G01K17/16
Filed: 1977-05-26
Abstract: Errors produced by sensors or by data processing are integrated by a calorimeter. Digital processing of the sensor output enables high precision to be obtained using standard equipment. A flowmeter in the secondary circuit of a heat exchanger produces pulses which are transmitted to a binary frequency divider. Outputs of thermometric probes are subtracted and applied to an analogue to digital converter whose output determines the frequency division ratio. The divider output is then applied to a binary frequency divider correction circuit operating from a temperature sensor signal. This provides correction of flowmeter output as a function of temperature dependent density. A counter provides an output reading.
