Abstract: 1,176,334. Heat shrinkable film. MINNESOTA MINING & MFG. CO. 12 Dec., 1966 [13 Dec., 1965 (2)], No. 55626/66. Heading B5B. [Also in Division B2] Biaxially oriented polymeric film with biaxially different heat shrinking characteristics is prepared by stretching a film of linear orientable crystallizable, heat settable polymer in a first direction at a temperature between T and T + 25‹ C., where T is the second order transition temperature of the polymer, thermally conditioning the film while it is maintained under tension in the stretched condition, by heating it for several seconds at 5‹ to 25‹ C. above said first temperature, and stretching the film in a second direction perpendicular to the first at at least 5‹ C. above the first temperature. The film should be stretched between 2 and 3¢ x in the first direction and 2 and 4 x in the second direction, and may be cooled whilst in the stretched condition before stretching in the second direction, by exposing it to an ambient temperature about or below the first temperature. Polyethylene terephthalate is the preferred film. Biaxially differentially heat shrinkable tubing may be obtained from the film, e.g. by heat-sealing.

Abstract: 1316505 Photographic film assemblies POLAROID CORP 23 Nov 1970 [24 Feb 1970] 55629/70 Heading G2A A film container and support means are designed so that they can be inserted into a photographic apparatus only when presented in the correct orientation. As shown, the film container 12 is so constructed that it fits into the support means 10 only when correctly oriented, the support means 10 being attached to the camera. Attached to the side walls 18 and 20 of the container 12 are rails 54 and 56 parallel to the forward wall 14 of the container, and which enter into channels 110 and 112 in the side walls 64 and 66 when container 12 is inserted into support means 10. The rails are located closer to the forward wall 14 of the container than to its rearward wall 16, so as to preclude the container being inserted into the support upside-down. Similarly an enlargement 58 at the end of each rail precludes its being inserted back to front. When the film container 12 is correctly inserted into the support 10, an exposure aperture 26 in the former is aligned with an exposure aperture 68 in the latter. The side walls 64,66 of the support 10 extend beyond the leading end wall 62 to define a recess 80. This receives a member 82 having a pair of electrical contacts 86,88 which extend through apertures 90, 92 in wall 62 for engagement with the terminals 42,44 of a battery located within the film container, so connecting the battery to electrically operated components of the camera. Figs. (not shown) 3-26 represent various modifications of interconnecting arrangements whereby it is ensured that the film container can be fitted into the support means only in the one correct way.

Abstract: 1284838 Combustion apparatus JUNKERS & CO GmbH 24 Nov 1970 [25 Nov 1969] 55768/70 Heading F1L A burner apparatus comprises a combustion chamber for the combustion of a fuel-air mixture, an exhaust duct connected to the combustion chamber, a condensate separating chamber being disposed at the outlet end of the exhaust duct and a condensate return duct extends from the separating chamber to a suction return device disposed within the exhaust. The invention is described with reference to a pulsating type combustion apparatus comprising a combustion chamber 10 having a resonant tube 12 which discharges into a silencer 14 to which an exhaust duct 15 leads to an outlet to atmosphere. A condensate separating chamber 17 is disposed at the outlet of the exhaust duct 15 and a condensate return duct 18 extends from the chamber 17 to a suction return device 19 at the upstream end of the exhaust duct. In Fig. 2 the separating chamber 17 is formed by a member formed with an annular recess 171 and an outlet opening 172, the discharge end 151 of the exhuast duct 15 projecting into the member. Condensate collects in the annular recess 171 when the apparatus is started and the condensate is returned to the exhaust duct 15 through a return line 18 which is connected to the throat 191 of a Venturi device 19 formed in the exhaust duct. In place of a Venturi device, the suction return device may comprise a funnel shaped member disposed in the exhaust duct, the small end of the funnel pointing downstream. In Fig. 4, a return duct 20 is disposed around the exhaust duct 15, condensate returning from the separating chamber 171 to the exhaust duct through a radial opening 152. Once the apparatus has been operating for a short time the exhaust duct attains the temperature of the exhaust gases so that no condensate is formed and the condensate return device ceases to operate.

Title: System for aligning in time the bits of a multi-bit character

Filed: 1969-11-18
Abstract: 1,260,578. Magnetic digital data storage. BURROUGHS CORP. 18 Nov., 1969, No. 56299/69. Heading G4C. In a skew correcting system the skewed data is passed a buffer store comprising a number of registers. Parity errors are corrected prior to reading data from the buffer. As shown, each 9-bit word from a magnetic store is passed over channels CH1-CH9 to register 12 and to register 18. The bi-stables in 12 are set to 1 only in response to 1-bits, but those in 18 are set to 1 in response to both 1 and 0-bits. When a bi-stable in 18 is set to 1 it sets to 1 the first free bi-stable in the corresponding N-bit register of counter 16: e.g. the first bit on CH1 sets BC11F to 1, the second bit sets BC12F, etc. The bi-stable in 16 thus set to 1 indicates in to which stage of the corresponding N-bit register in buffer store 10 shall the bit stored in 12 be placed: e.g. if a bit occurs on channel 1 and BC12F in 16 is set to 1 in response then SB12F in buffer 10 assumes the state of the received bit. When any register of counter 16 is full (i.e. when there is a 1-bit in any bi-stable BCxNF) and the corresponding bi-stable of register 18 is in the 1-state, indicating that one of the registers in buffer 10 is full and that a further bit for that register is waiting in register 12, the word stored in bi-stables SB11F-SB91F of buffer 10 is read out in parallel-bit form to buffer 14, after parity correction if necessary. The data in buffer 10 is now shifted one stage to the right, as is the count in counter 16, so permitting the bit in 12 to be stored in the relevant register. The system corrects the word in SB11FSB91F in two instances. In one instance control circuits 20 detect drop-out of signals on any channel CH1-CH9. If drop-out is detected the corresponding bi-stable in register 22 is set to 1 and the corresponding registers in buffer 10 and counter 16 are prevented from responding to further data on this channel. Prior to reading the word from buffer 10 a parity check is made on it and if error is found the state is reversed of that bi-stable SBxlF in buffer 10 which corresponds to the bi-stable in 22 set to 1. In the second instance, when a word is required to be read out, as shown by the state of counter 16 and register 18 (see above), if any register in counter 16 contains no 1-bits, indicating that no data has been received on the corresponding channel, then the corresponding stage of register 22 is set to 1, causing parity correction of the word as described above.

Abstract: 1,164,810. Processing spent nuclear fuel. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 11 Dec., 1967 [19 Dec., 1966], No. 56718/66. Heading G6R. [Also in Divisions C1 and H5] Nuclear fuel such as uranium or plutonium oxide or carbide which has been subjected to fission in a nuclear reactor undergoes a meltreprocessing by a process which comprises establishing an arc between an electrode and a cooled crucible, feeding the fuel to be melted by the arc into the crucible and simultaneously rotating the crucible about its axis of symmetry, whereby the molten material is flung therefrom and allowed to solidify without substantial contact with a solid surface. The process will remove the volatile and gaseous fission products but the material will still be contaminated with heavy metal fission products. The fuel to be reprocessed by melting may contain sodium and after the process the fuel can be reloaded into cans ready for re-use in a nuclear reactor. The arc is struck between the electrode and crucible prior to feeding the refractory material to the crucible and the gas atmosphere is argon at reduced pressure. The crucible is rotated preferably at speeds between 200 and 2000 r.p.m. The apparatus comprises a copper crucible 1 located within a furnace drum 4. A vacuumtight connection is made between the crucible mounting means 5 and the base 6 of the drum furnace 4. Water inlet and outlet pipes 7 are provided for conveying cooling water to cooling passages 2. The mounting means 5 include a spur gear 8 which is in mesh with a second spur gear 9 on shaft 10 for rotating the crucible. Power supplies for crucible 1 are provided by conductors 11 and brushes 12. At the top of the furnace extension 14 is a top plate 19 carrying a central column 21 which houses an electrode support 22 which is water cooled by means of pipes 23 and carries a bus-bar 24 for connection to the electricity supply by conductors 25. At the lower end of support 22 is a water-cooled graphite electrode 26 which has an internal bore 28. Provision is made by a screw mechanism 30 for adjusting the effective axial position of electrode 26 and the assembly comprising the support 22 and electrode 26 is capable of axial movement within the column 21 so as to permit the arc to be struck by engaging the electrode 26 with crucible 1. A container 31 mounted on top plate 19 is provided with flow control means and is connected by means of a flexible pipe 32 to bore 28 of electrode 26 through which refractory material is fed from container 31.

In the primary system, the power jets 27, 30 and 33 of fluidic amplifiers 28, 31 and 34 are supplied through variable restrictors from the manifold and the first amplifier has control ports 47 and 48 to which a signal from a valve 20 corresponding to cabin temperature and a valve 11 corresponding to rate of change of temperature are applied, the signals being opposed by bias pressures applied to ports 46 and 49. A bleed 82 compensates the bias signal at port 46 for changes in altitude. The outputs 35, 36 from the amplifier 28 are applied through the remaining amplifiers and a valve 68 to a relay 14 actuating a temperature control valve 15 regulating supplies from cold and hot air ducts 2, 3 to a mixer 4. The relay 14 is also controlled by a detector 13 responsive to the pressure drop across an ice screen 5 and by a temperature over-ride control 10 downstream of a water extractor 6. A flow of cabin air 18, 19 passes across the valve 20 which is operated by a bi-metallic strip 16 situated in a wall attachment ejector pump 17 and set by a bellows 21 connected between the manifold 26 and a needle valve 67. To linearize the response characteristics with changes in altitude, a restrictor 81 is also provided. The stand-by amplifier has a control port 58 at which the pressure is controlled by a stand-by temperature sensor 9 and is opposed by a bias pressure at port 57 controlled by needle valve 69, the output from the amplifier being applied to the relay 14 through a valve 70. The valve 15 may be replaced by a louvred vent or blower motor.

In a method of manufacturing a roller or needle bearing cage, an apertured strip 1a, the end portions 5, 6 of which define complementary parts of an aperture 12, is rolled to shape and clamped between jaws 2, 2<SP>1</SP> each of which has an electrode portion 29, an insulated spacer member 14 is inserted in the aperture 12 and resistance butt welding of the rim portions 7, 8 carried out, the spacer 14 serving to limit the amount of upset of the rim portions. The clamping pressure is reduced to allow withdrawal of the spacer and finally released after cooling. The spacer may be tapered or parallel sided (Figs. 5, 6, not shown) and may be recessed to accommodate roller-retaining lips on the aperture edges. A locating stud 23 serves to locate the strip accurately for the welding process. The abutting faces 9, 11 of the rim portions may be offset from the median plane of the aperture 12 so that any internal weld bead formed in the aperture is disposed at a position in which it does not contact the convex end face of the needle or roller. The clamping jaw faces are recessed (Fig. 2, not shown) so that pressure is only applied to the rim portions of the strip, and the electrode is similarly arranged (Fig. 3, not shown) to apply pressure and welding current only to the rim portions.
