Abstract: 1,165,344. Seals. JOSEPH LUCAS (INDUSTRIES) Ltd. 13 Feb., 1967 [9 Dec., 1965], No. 52219/65. Addition to 1,110,119. Heading F2B. The sealing ring 12 and groove 11 of the parent Specification are of such size that substantial movement of the backing ring 13 towards the base of the groove is prevented, the relationship of the sizes of the groove and sealing ring allowing expansion of the sealing ring within the groove. The arrangement prevents the backing ring 13 from being damaged during assembly. Expansion of the resilient ring 12 under operating conditions is accommodated by the chamfered edge of the groove remote from the backing ring. If desired, the groove may have a cross-section of truncated triangular form.

Patent GB-1541332-A (GB)
Title: Colour picture projection apparatus
IPC: H04N9/31
Filed: 1977-12-16
Abstract: The projector includes three cathode ray tubes with associated deflection devices, and an arrangement of projection lenses in front of each cathode ray tube, to project the pictures which are generated on the screens onto a concave projection screen (4). The cathode ray tubes and their projection lens arrangements are arranged vertically one over the other, as projection units (1, 2, 3). With this arrangement, geometrical errors in the projected picture, which are caused by projection, must be corrected in the horizontal direction only, and for a viewing audience which is mainly spread out horizontally, the picture is reproduced with less distortion than with arrangements which also require picture error correction in the vertical direction. <IMAGE>

Title: Device for Regulating the Rate of Flow of Gas
IPC: F17C7/00
Filed: 1966-12-01
Abstract: 1,166,495. Mixing gases and powders. INSTITUT DE RECHERCHES DE LA SIDERBURGIE FRANCAISE. 1 Dec., 1966 [14 Dec., 1965], No. 53841/66. Heading B1C. [Also in Divisions C7 and G3] The overall flow rate of a gas which is to be divided between main and auxiliary delivery conduits 13, 15 respectively, is kept strictly constant whilst the delivery through the auxiliary conduit 15 is adjustable by a valve 16. The flow before branching is passed through a venturi 8 operating at or above the critical pressure drop. The upstream pressure is held constant in a supply tank 7 by regulating means 10, 11, 12. In order to maintain a constant pressure downstream of the venturi, the loss from the main conduit 13 through the branch conduit, is compensated as regards pressure by a regulating valve 14 downstream of the branch which is responsive to the main conduit pressure through a regulator 19. The device controls the supply of oxygen to the lance 1 of an apparatus (not shown) for refining pig iron into, steel. Whilst the main flow issues directly from a central tube 2, the auxiliary flow is directed at right-angles into the issuing jet through an annular space 4. By adjusting the auxiliary flow, the divergence of the jet is varied as required. In a variant, Fig. 2 burnt lime in a container 21 is fluidized and its flow into a main oxygen stream 13 regulated by auxiliary streams 30, 31, 32 which rejoin with the mixed stream. The fluidization is effected through a valve 33 and screen 25. Coarse regulation of the lime flow is effected by maintaining constant pressure in the container through regulator 34, 36 and outlet restrictor 38. For fine regulation of the lime flow, the outlet pipe (26) is interrupted by an annular gap 27 and oxygen is injected at right-angles into the stream under the control of a regulator 39, 40.

Abstract: 1,151,240. Measuring combustible gas concentrations, electrically. R. HœBNER. Dec.3, 1966, No.54208/66. Heading G1N. In a portable methane gas detector for mines there are two heated catalytic resistor filaments R 1 , R 2  Fig.1 and two heated non-catalytic reference filaments R 3 , R 4 , mounted in a chamber into which a gas sample is drawn through a duct 11 by a pump 17. The resistors form the arms of a bridge connected to a stabilized D.C. source through circuitry which ensures that the bridge is not energized until the pump finishes pumping. With methane concentrations up to 5% the catalytic combustion effects predominate to produce an indication on the bridge meter 21 in sector 21a Fig.2. With higher concentrations there may be insufficient oxygen to sustain combustion and the resistance of the filaments is determined by the thermal conductivity of the gas, which produces a greater heat loss from the higher temperature filaments R 1 , R 2  than from the lower temperature reference filaments R 3 , R 4 . In consequence the bridge is unbalanced in the opposite direction and the meter is calibrated to indicate accordingly in sector 21d.

Similar cams can be provided in the upper cylinder. The movement of the sinkers can be used during the one feed reciprocatory knitting of heels and for the formation of plush loops in the sole, some butts 12a being longer than others so that plush loops may be laid over these sinkers. The sinkers may also be used during the formation of a welt or suitably controlled to produce ladder stop courses.
