Title: Filter sleeve for removing dust from gases - with several coaxial cloths, giving reduced volume and easy maintenance
IPC: B01D46/06
Filed: 1974-10-25
Abstract: A tubular filter sleeve for removing dust from gases has several tubular cloths inside one another, connected at the ends. It is made from a sleeve, which is in the form of a truncated cone, by turning the narrow end upwards inside the sleeve towards the larger end, then downwards, and so on. The resulting shape may be conical or pyramidal, formed by inserting a suitably shaped support made from rigid wire suspended in a frame. A grid may be put between the wires. The filter occupies less vol. from a given filter surface than existing filters, the velocity of gas through the cloth is substantially constant and laminar, wear is uniform, and the filter is easy to clean by reverse flow.

Title: Electronic measurement of machining size on machine tool - detects errors in system and alerts operator and indicates cause of error
IPC: G05B19/23
Filed: 1975-04-07
Abstract: The machining size indicator is electronically operated by a transducer. Impulses fed into the counter depend on the direction and the circuit. These are totalised, memorised and displayed. A logic system detects counting errors. It comprises a counter with automatic zero reset. This occurs when the first zeroing impulse is received at the start of an operation and must be zero at each reference impulse. A detector circuit permanently checks that the counter is on zero each time. If not, an alarm circuit operates. To determine the origin of the error, a signal lamp lights up to indicate its nature.

Title: Memory for data in keyboard sequence - has rapid storage and retrieval by keyword comparator controlling shift register
IPC: G06F17/30
Filed: 1975-05-06
Abstract: A memory for data consists of a keyword and sets of data, with a shift register (RSR, MSR, LSR) for the sets of data and a terminal from which the data can be fed out in sequence, leading to a comparator (10) in which the keyword (K) of the momentarily fed-out data is compared with a wanted keyword, and whose output controls the feed-in or feed-out through the terminal to the shift register, the data stored on one or other side of the connecting lead being suitably shifted when a set of data is to be fed in or out. Then shift register may be a linear two-way register with the connecting lead in its centre. The arrangement facilitates the easy recording of data in the order of the keywords, with correspondingly simple retrieval.

Abstract: 1527228 Light guides POST OFFICE 10 Dec 1975 [18 Dec 1974] 54764/74 Heading G2J Apparatus for launching, Fig. 1 or detecting, Fig. 2 radiation in selected modes in a core/cladding waveguide comprises a tapered section 3, 20 of waveguide, long compared to the wavelength, and a prism 6, 21 of R.I. greater than that of the cladding positioned adjacent the waveguide either at, but not overlapping, the tapered section 3, 20 or at least partially overlapping it. To launch radiation, Fig. 1, light from laser 10 passes through prism 16 and enters the waveguide core in a weakly bound mode which is transformed to a selected, strongly bound mode by travelling in the outwardly tapering section 4 before reaching the main waveguide part 5. To detect radiation, Fig. 2, radiation in a selected mode in waveguide 5 is transformed to a weakly bound mode by travelling in the inwardly tapering section 20 and is then extracted by prism 21 so as to impinge on defector 23. An index matching liquid 8 may be present between the prism and the waveguide. The waveguide may be of sodium borosilicate glass having an external diameter tapering from 70-100Ám down to 12-15Ám and a core diameter which tapers from 12Ám to 3Ám.

Title: Collapsible fishermans keep net with rod handle - has recoil mechanisms for extension and three way hinge joining rod to net support arms
IPC: A01K77/00
Filed: 1976-01-21
Abstract: The fishermans keep net with a telescopically retractable rod handle includes a three-way hinge at the junction of the rod and the two branches supporting the net. The net and handle assembly folds and retracts down into a compact protable form. The hinge and the telescopic mechanism are recoil sprung whereby the assembly is automatically extended upon the release of catches. The hinge permits relative pivoting between the rod and the net support branches, and also permits the branches to pivot relative to one another. The net is, thus, retracted by bringing the branches together and then pivoting them into a position approx. adjacent to and in alignment with the rod.

Title: Pen tip made of nonporous oxide ceramic - and possessing surface grooves for the passage of ink
IPC: B43K1/00
Filed: 1976-12-09
Abstract: The pen tip is made of material which is impermeable to the ink, and the ink flows along directional channels in the surface of the pen tip. The essential constituent in the pen tip is pref. (a) Al2O3, (b) BeO, (c) ZrO2, (d) TiO2, or (e) a mixt. of the oxides (a,b,c,d). The oxide(s) pref. constitute 80-100% of the ceramic mass, esp. 90%.

Title: Hydraulic jack with increased force at end of stroke - has secondary piston with wedge on end of piston rod
IPC: F15B15/20
Filed: 1976-12-28
Abstract: A hydraulic jack has a cylinder (1) with a main piston (2) which houses an inner secondary piston (6). The secondary piston has a piston rod with a wedge shaped end (4) which acts against the end surfaces of radially arranged wedges (3). These radial wedges slide in slots (5) in the main piston (2). When the main piston approaches the end of its stroke the wedges are forced radially outwards and their outer ends engage the sloping surface (7) of the cylinder end cap (8). The reaction from the cylinder end cap produces an additional force in the axial direction which is transmitted to the piston through the surfaces of the slots in which the wedges are fitted.

Title: Solution polymerisation partic. of diene(s) - in which solvent is removed by thin film evaporation
Inventor: DELCLOS A
IPC: C08C2/06
Filed: 1977-03-14
Abstract: One or more monomers are polymerised in soln., the solvent being removed by evanpn. of a thin film of the polymer soln. The evapn. is effected under a partial vacuum of 200-500 mm Hg at a temp. of 100-200 degrees C. An anionic type initiator is pref. used. The monomer is pref. a diene. Polymerisation in soln. is usually followed by pptn. of the polymer by a non-solvent. However, if the polymer is not a solid it is difficult to separate it entirely from the solvent and the non-solvent. Also, sepn. of the latter two liqs. from each other involves a supplementary stage. thin film evapn. eliminates these problems. The method is applicable to polymers which are not subject to heat degradation, e.g. polyethylene or polyisoprene.

Title: Animal restraining cage mounted on tractor three point linkage - has cable connecting support to towing point to tilt cage on lifting for locking in horizontal position by catch
IPC: A01K15/00
Filed: 1977-04-15
Abstract: A bottomless cage is rotatably mounted about the middle of its rear wall and is carried by the three point linkage of a tractor. A support on the rear wall of the cage is connected by a cable to the tractor towing point. The open bottom enables the cage to receive an animal and straps are provided to hold the animal. On raising the lift linkage, the cable causes the cage to pivot, laying the restrained animal safely on its side. The cage latches in this position and the linkage is re-lowered so the animal can be tended safely at a convenient height.
