The ceiling is strengthened to receive concrete by parabolic shaped hardboard panels 34 and wood struts 35, 36. The wall panels consist of flat steel sheets each of which has a corrugated steel panel welded to it or consist of plasterboards nailed to wooden posts or formed with a plaster plank therebetween. External wall panels of fibreglass lined with plasterboard may be used with concrete therebetween. Units are located one on another by pins or dowels and may be provided with service accessories, furniture and internal decorations as necessary.

Title: Disposable diaper
IPC: A61F13/15
Filed: 1972-01-11
Abstract: 1377801 Laminated diapers JOHNSON & JOHNSON 11 Jan 1972 1185/72 Heading B5N [Also in Division A5] A multi layer diaper comprises a porous facing layer 16 of water wettable mixed long fibres (between ¢ inch and 2¢ inches in length) and short fibres (less than about  inch in length), a porous batt 14 of loosely compacted short cellulosic fibres such as wood pulp fibres or cotton linters (which may be blended with other fibres), said bolt having greater wettability than the facing and disposed in face to face juxtaposition with the facing, and a water impervious backing sheet 12 on the other side of the batt. The backing sheet, e.g. polyethylene, polyethylene terephthalate, is adhered to the batt by bead lines 22 of adhesive running longitudinally down the length of the diaper, which is rectangular. The facing sheet overlaps the batt at the longitudinal edges and is also adhered to the longitudinal margin of the backing sheet by bead lines 22. The longitudinal edges of the facing sheet may be folded inwardly at the edges of the diaper, Fig. 3 (not snown). A second batt (20) of larger dimensions than the first batt may be placed in juxtaposition with the first batt to give a stepped appearance, Fig. 4 (not shown), and the backing sheet adhered to the second batt. Similarly one or more layers of creped cellulose wadding may be interposed between the batt 14 and the backing sheet, the ridges of the crepe running longitudinally. The facing layer comprises from about 75 to 98 weight per cent of short fibres, and from about 2 to 25 weight per cent of long fibres, the fibres being bonded by a water repellant polymeric bonding agent, e.g. a self crosslinking acrylic emulsion, and treated with a surfactant. The long fibres may be of rayon and the short fibres may be as used in the batt 14. The facing layer has a weight of about 1 to 5 ounces per square yard, and a density between about 0À05 and 0À1 gms. per c.c. The batt has a density between about 0À10 and 0À20 gms per c.c. The diaper may be folded longitudinally at its edges for use, there being tabs 4 (26) at the corners of one end, Fig. 6 (not shown), by which it can be folded around an infant.

Title: Improvements in or connected with permutation locks
IPC: E05B37/00
Filed: 1919-01-17
Abstract: 142,528. Caddy, S. C. Jan. 17, 1919. Locks, permutation. - The lock is constructed w i t h notched disks 7, 9 mounted co-axially on a spindle 10 and sleeve 11 respectively in a casing 1 and adapted for independent rotation to aline the notches 7a, 9<a> with a cross-pin 21 of a sliding bolt 20. The necessary rotation is ascertained by sound or feel produced by contact of adjustable lugs 6, 8 on the respective disks with circular sets of fixed projections 4, 5, such contact being yieldingly maintained by a spring 22 arranged between the disk 9 and a fixed disk 15 on the sleeve 12, and by a spring 17 between the sleeve 12 and spindle 10. An enlarged gap in each set of projections serves as a starting point in setting the disks, which is effected, as regards the disk 9, by a knob 14 on the sleeve 11 and as regards the disk 7, by a sleeve 12 carrying a knob 13 and engaging through a one-direction clutch and pin 16 with the spindle 10. The additional notched disk 15, which is optional, is mounted on the sleeve 12 and set by trial after the disks 7, 9 have been set in predetermined position. The combination can be varied by connecting the lugs 6, 8 with the disks 7, 9 adjustably, as by a pin on the lug engaging one of a circular set of holes in the disks.

[Class 20(iv)] In a screw bolted scarf joint between two reinforced concrete elements, such as girders or columns, each of the jointed ends of the elements is strengthened by a number of additional longitudinally extending reinforcing members embedded therein. In the form shown, two contiguous elements 1 and 2 are scarfed together along the line A B B<SP>1</SP> A<SP>1</SP> and secured to each other by screw bolts 5. In addition to the normal reinforcement 3, reinforcing members 6 are provided in each reduced end. The sliding of one element on the other is prevented by a projection 8 on one end engaging in a recess formed in the other. The Specification as open to inspection under Sect. 91 states that the projection 8 is provided with its own reinforcement. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,269,621. Recording apparatus. BRITISH PETROLEUM CO. Ltd. 10 April, 1969 [10 Jan., 1968], No. 1492/68. Heading G5R. Tape speed variation in a vehicle data recording system is compensated using reference pulses recorded in a separate track. As described, manifold pressure and road speed information is converted to pulse density modulation (P.D.M.) format, engine speed information derived from the distributer is shaped, and the three pulse trains recorded in separate tracks. A 150 Hz reference pulse train is recorded in a fourth track. The tape, which may be in a magazine, is played back on a separate machine, and the vehicle data is shaped to provide constant width pulses whilst an error signal, derived from the reference track by integrating the pulses reproduced, is subtracted from the data which is then converted to analogue form and fed to an ultraviolet galvanometer or pen recorder or punched on to tape. Transistor circuits performing the various operations are detailed.

Title: Cracking butene oligomers
IPC: C07C4/06
Filed: 1962-01-16
Abstract: Oligomers of butene are cracked or depolymerized by contact at elevated temperature with a phosphate of aluminium and/or boron. The feed is preferably di-isobutene and/or tri-isobutene or a n-butene-isobutene copolymer.  The catalyst may be supported, e.g. on silica gel or activated alumina and may also contain 0,03-1% of nickel as a salt thereof.  Cracking is effected at 220 DEG -320 DEG C. and at or near atmospheric pressure, e.g. 4-8 atmospheres with a throughput of 0,5-3 kg./litre of catalyst/hour.  The product from di-isobutene is isobutene, tri-isobutene also yields the dimer which may be separately cracked or recycled. Iso-butene-n-butene copolymers yield higher than theoretical amounts of isobutene.

Title: Improvements in photographic cameras
IPC: G03B17/42
Filed: 1937-01-20
Abstract: 482,537. Photographic cameras. DECKEL, F., (trading as DECKEL, PRAZISIONSMECHANIK UND MASCHINENBAU, F.). Jan. 20, 1937, No. 1726. Convention date, Jan. 21, 1936. [Class 98 (i)] In cameras having a shutter manually tensioned for each exposure, and a manually actuated feed mechanism for the light-sensitive material which is automatically locked after each feed, the feed mechanism is unlocked at or approximately near the completion of the exposure by a device put into operation by the shutter action. As shown the take up spool 2 operated by a knob 3 drives through gears 6, 7 a roller 4 having teeth engaging the film and carrying a detent device to prevent rotation of more than 360‹ at a time. The roller carries a cam disc 8 engaged by a pin 12 on a spring-pressed arm 9 pivoted at 10 and carrying a sliding bar 13 having a lug 15 engaging a pin 16 on the tensioning arm 17 of the shutter 18. The pin 16 engages a slot in a slide bar 24 pivoted to a lever 23 engaging a nose 22 on the bar 13. On winding the film the cam disc 8 moves the slide 13 to the right thus winding the shutter by engagement of the lug 15 with the pin 16. The tensioning arm 17 is then locked automatically by the shutter mechanism after which the lever 9 moves back under the action of the spring 11 and the pin 12 thereon engages a slot 25 in the cam to lock the feed. When a pin 21 is depressed to release the shutter the arm 17 moves to the left until it strikes the end of the slide 24 which, by means of the lever 23 moves the slide 13 to the right and releases the pin 12 from the slot 25. The camera may be provided with a device to permit operation of the shutter only when the film has been wound or the shutter tensioned.
