Title: Improvements in or relating to photographic film spools
IPC: G03B17/30
Filed: 1931-10-20
Abstract: 388,854. Photographic roll-film spools. BAXENDEN, T. G., Lawrenny, Hempstea-d Road, Watford, and COLLYEAR, J. R., Leverno, Beechcroft Road, Bushey, both in Hertfordshire. Oct. 20, 1931, No. 29113. [Class 98 (i).] The cylindrical body 1 of a flanged roll-spool is rolled up from a sheet - metal blank whose length is greater than the periphery of the rolled body, so that one end overlaps the other to form a clip 7 under which the end of the film is inserted and gripped. The portion of the body underlying the clip may be depressed so that the clip lies in the depression with its edge flush with the rest of the body. This construction may be modified by forming the clip 7 from a separate piece of metal, and welding or brazing it at 8 to one edge of the depression in the rolled body. End discs 2 with key and pivot holes 10 are held by flanges formed on the ends of the body (except at the clip), and may be secured in position by compressing them in the direction of the axis of the spool as described, for example, in Specification 299,605, [Class 98 (i), Photographic cameras &c.]. Reference is made to a construction of spool having a clip riveted to the spool body.

Title: Improvements in or relating to the heating of feedwater in steam boiler or hot waterboiler plants
IPC: F22D1/02
Filed: 1947-11-04
Abstract: 653,265. Feedwater heating systems; forced-flow steam boilers; heating buildings. DALIN. D. Nov. 4, 1947, No. 29408. Convention date, Sept. 9, 1943. [Classes 64(i), 64(ii) and 123(ii)] In a steam or hot-water boiler plant a current of the boiler circulation water, or a mixture of the circulation water and steam, drawn from a collecting drum 2 forming part of the boiler plant, is divided into at least two streams, one of which heats the feedwater in a heat-exchanger 9 and another of which is conducted to heating surfaces 8, 16 exposed to the flue or like gases, the circulation water or steamwater mixture and the feedwater both being positively circulated through the heat-exchanger, e.g. by pumps 13, 14. The part flowing through the feedwater heater 9 is reheated in the heater 5 in the flue 4. Steam from the drum 2 is superheated in the superheater 6. In a modification the heaters 6, 16 are replaced by a second reheater for the circulation water from the feedwater heater 9. In another form a third stream of the hot water drawn from the drum 2 heats a liquid in a heat exchanger and is reheated in waste heat boilers before return to the drum 2. In another form feedwater is heated in two feedwater heaters, between which it passes through a degasifier. The Specification as open to inspection under Sect. 91 describes also arrangements in which all the water withdrawn from the drum passes through a water heater. In one form steam generated in the water heater passes to a superheater. In another form, boiler water, after generating steam in a heat exchanger, is reheated partly in two flue heaters and partly in furnace tubes. In other forms, boiler water or steam from the drum heats a separate steam generator and a water heater which supplies water to that steam generator. In another form, boiler water circulating from the drum through a heat exchanger heats water circulated through radiators. In another form, Fig. 7 (Cancelled), steam and water from waste heat boilers 32 pass to a common drum 30, and then through a coil 65 in a steam generator 29 before return to the boilers 32. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in key operated catch-locks, particularly suitable for attache cases, bags, boxes and such like
IPC: E05B65/50
Filed: 1923-11-22
Abstract: 224,727. Cheney, C. W. Nov. 22, 1923. Hasp locks; locking sliding latches; lock mechanism, spring tumbler type. -In a hasp lock having a latch bolt blocked by a key-shot blocking bolt, the blocking bolt carries a limb spring which forms the locking tumbler for the blocking bolt and may also form the spring of the latch bolt. Fig. 3 shows one form of the invention in which a bolt proper g has a head g<2> for engaging the hasp, a pair of guides g<5> for the blocking bolt a and a gating g<1> for co-operation with the tumbler c. This tumbler spring c has two limbs c<2>, c<3>, held under the folded-over edges a<3>, a<2> respectively of the bolt a, and a part c<4> bent at right angles and working in a slot a<4> in the bolt a. In the position shown in Fig. 3, the part c<4> is engaging a stop f<3> on the casing so that the bolt g can be manually retracted, the bolt g and blocking bolt a moving bacliwards and the spring end c<4> being held by the stop f<3> and travelling down the recess a<4>. If the key is inserted and turned on the pin g<3>, it releases the tumbler c<3>, c<4> from one side of the V of the gating g<4> and moves the bolt a to engage behind the stop f<4> while the tumbler engages the other side of the V-gating, locking the bolt g against retraction. The spring c also forms the shooting spring of the bolt g. In the form shown in Fig. 11, the blocking bolt a moves in a recessed part of the bolt g and the spring tumbler c<4> coacts with a stud g<4>. In the position shown, the bolt g can be manually retracted against the spring c but when the bolt a is shut so that the bent-over flange is behind the shoulders s<3>, the bolt g is locked. Fig. 15 shows a further form in which the blocking bolt lies parallel with the axis of the bolt g. As shown, the bolt g can be withdrawn against its spring x. If the bolt a is moved forwards, the tumbler spring c<4> comes in front of the stop f<4> and the end of the bolt a behind the head g<2> of the bolt so that this cannot be retracted.

Abstract: 1357652 Character recognition systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 June 1971 [27 June 1970] 29701/71 Heading G4R A system for determining the position of a character on a document relative to the length of a line of photo-sensitive elements which scan the document includes a number of adding units, each receiving signals from a respective group of the elements. There are at least three such groups and the groups overlap one another. In one embodiment, Fig. 2, the line of photosensitive elements EF scans horizontally across the character. The length of the line EF is greater than the height of the character. Groups of the elements are connected to adders 28-30. Each group has the same number of elements and is of a length equal to the character height. The adder outputs are integrated over the width of the character by units 31-33 which feed a unit 34 which determines the position of the character. The outputs of the integrators may be connected time sequentially to a filter, the position of the peak of the filter output signal indicating the position of the centre of the character. The filter output may be differentiated to provide a zero cross-over at the peak output.  In a second embodiment, Figs. 3 and 4 (not shown), there are two sets of groups of photosensitive elements. The sets are spaced vertically by a distance equal to the height of the character. When the character scanned is correctly positioned there is no output from either set.
