Title: Improvements in or relating to multiple bladed knives
IPC: C14B5/04
Filed: 1945-06-22
Abstract: 601,261. Fur-cutting knives. BECKER, M. E. June 22, 1945, No. 16020. Convention date, May 16, 1944. [Class 30] A fur-cutting knife comprises a holder having a pair of side plates to clamp two or more spaced cutting blades which are mounted on at least two blade supporting and positioning keys extending between the side plates, one or both of the plates beingmounted for pivotal movement into and away from clamping position. As shown in Fig. 1, a holder 20, T-shaped in cross-section, is provided on each side with two triangular keys or posts 28 on which are mounted two cutting blades 31 having pointed ends 34 projecting beyond the holder. Two side plates 21, 22 pivoted to the holder 20 at 23 are sprung to pass over and engage the posts 28, and a bolt is then passed through them and the holder to clamp the parts together. In a modification having four blades, the upper part of the holder is broadened and the keys 28 are lengthened to carry on each side a spacing block and another blade; in this form the blades are reversible having cutting points at each end. In another modification, Fig. 5, the holder 61 is formed with a side part 65 which carries a post 66, angular in cross-section, and has a hole to receive a bolt 67. Blades 62 and spacing blocks 71 alternately are placed on the post 66 and bolt 67 which then receive a side plate 72 pivoted at 73 and the parts are clamped. In this form the distance between the pairs of blades can be varied by using spacing blocks of different widths. The Specification, as open to inspection under Sect. 91, describes also a blade 81, Fig. 11, (Cancelled), having one triangular hole 83 and a dove-tailed extension 84. This subject-matter does not appear in the Specification as accepted.

Abstract: 349,772. Motor bonnet fastenings. ROBINSON, F. J., 11, Warwick Row, Coventry. May 27, 1930, Nos. 16285 and 30559. [Class 44.] A fastener for securing motor-car bonnets &c. comprises a wire member 9 bent to U- form, the outwardly-turned lower ends 10 of the limb being sprung into apertures in a U-form bracket 4 to provide a pivoted mounting of member 9, the bracket 4 being also pivotally mounted on a baseplate 2 by a pin 8. A flattened tube 12 is telescopically mounted on member 9, a spring 13 being interposed between the cross-limb 11 of member 9 and a pin 14 passed through tube 12. The upper end of tube 12 may be further flattened and bent to provide a fingerpiece 13, a perforation 16 being provided to engage the usual stud on the bonnet (not shown). Alternatively, a separate perforated finger-piece may be welded to tube 12. Pin 14 may carry a rubber &c. buffer 17 to bear against the bonnet.

Title: Improvements in or relating to thermionic valves
IPC: H01J1/18
Filed: 1927-06-20
Abstract: 273,293. Tourne, C. June 22, 1926, [Convention date]. Vacuum tubes. - A valve has a continuous filament of length equal to that of several sections of active filament, and means for replacing a burnt-out or defective section without opening the bulb. As shown, the length of filament not in use is carried by a bobbin 6, and the filament passes through a tubular guide 7 and is secured between a fixed lower clamp 8 with spring jaws, and an upper spring clamp 8<1> sliding in a tube 9, which is screwthreaded to receive a bar 10 of soft iron with guides 11 operating in a slot in the tube. Rotation of the bar by means of an external magnetic field thus causes longitudinal movement of the clamp 8'. A burnt-out section of filament is replaced by causing the clamp 8<1> to move downwards so that it passes over the clamp 8 and its jaws are opened thereby and subsequently closed to grip the filament. The clamp 8<1> is then moved in the reverse direction so as to open the jaws of the lower clamp 8, which close subsequently so as to grip the filament, but less tightly than the clamp 8<1>. The electrode structure is held within the bulb by springs 13. The vacuum may be improved by burning out several sections of filament.

Abstract: <PICT:1005072/C4-C5/1> In an optical information display apparatus, such as for producing a trace, representing the course of a moving object, superimposed on a map, a photochromic film 24, Fig. 2, is used which is normally in a clear transmissive state but is rendered light absorptive by ultraviolet light, and the composite image produced on the film 24 is projected by a lens system 26 on the screen 12. To increase the persistency of the traces on the photochromic film 24, the latter is enclosed in a refrigerated chamber and a number of such films may be mounted on a disc for selective interposition into the beam.

Patent GB-571441-A (GB)
Title: Dehydration of animal material for surgical purposes
IPC: F26B5/00
Filed: 1942-11-21
Abstract: A method of dehydrating animal material adapted and intended for surgical purposes, e.g. catgut, includes heating the material with the exclusion of air therefrom to a water removing temperature in an organic liquid having a boiling point above 110 DEG C. and a solubility for water not greater than 5 per cent. or in a mixture of such liquids.  The boiling point of the liquid may be between 111 DEG C. and 397 DEG C., and its solubility for water between 0.1 and 0.3 per cent.  When the boiling point of the liquid is above 165 DEG C., continuation of the heating effects sterilization of the material. In an example, catgut is heated in tetradecanol for 5 hours at 109 DEG C. to dehydrate, and then in the same liquid for 5 hours at 165 DEG C. to sterilize.  When the dehydrating liquid boils below 165 DEG C., it may be replaced by a higher boiling liquid for sterilization, as illustrated in another example in which catgut is heated in toluene for 5 hours to 109 DEG C., and the tubes refilled with xylene and heated in a bath of pseudocumene to 165 DEG C. for 5 hours.  The animal material is left in the tubes until cool, the liquid drained off and immediately replaced by a tubing fluid, such as ethyl alcohol to which potassium iodide and red mercuric iodide have been added, and the tubes are then hermetically sealed.  A list is given of suitable organic liquids which may be used alone or mixed with one another.  The Specification as open to inspection under Sect. 91 is not limited with regard to the boiling point of the organic liquid used.

Title: Improvements in cash registers
IPC: G06C7/10
Filed: 1921-06-17
Abstract: 165,043. Krupp Akt.-Ges., F. June 18, 1920, [Convention date]. Cash registers; operating by motors.-In machines of the type in which a lever normally locking the operating-mechanism is released and the operating-circuit closed by the successive setting of amount and special transaction keys, an idle key is provided for effecting this release when it is required to test the operation of the machine without registering or when access to the till is desired. The machine described has five banks of amount keys A and one bank of special transaction keys B' and each bank co-operates with its detent sector H<1> or H<3> pivoted on a shaft H and locked in either of its positions by a notched rocking plate J' actuated towards the end of the operation of the machine to release the sector and depressed key by means of a pin m<2> and slide-bar K. When an amount key is depressed, the corresponding sector H<1> rocks and through an extension carrying a roller pushes back a bail Q mounted for oscillation on a shaft F'. A bellcrank lever S is consequently rocked and frees a lever F abutting against an arm C<2> fixed to the main operating shaft C and also engaging a spring-controlled disc D capable of relative movement to a slight extent with respect to the arm for circuit-closing purpose when the lever F is moved out of engagement. This unlocking movement of the lever F is effected by the depression of one of the special transaction keys B<1> which causes a plate R to slide rearwardly and through an arm F<2> to rock the lever F clockwise (Fig. 2). During the rotation of the main shaft the depressed keys cannot be released since the shaft J carrying the locking-plates J<1> is prevented from rocking by the interposition of a pin p<3> on one arm of the bell-crank P<1>, the other arm of which is controlled by a cam groove on the disc D. When the idle key B is depressed it first rocks a lever T so as to operate the bell-crank S to free the lever F and then slides the plate R to the rear to rock this lever F to release the operating- shaft and start the machine. An interlock between the key B and the other keys is provided by a lug t<5> on the lever T which co-operates with the bail Q. The key is released at the end of the operation, by the rocking of shaft J with which it is connected by a key-holding pawl U and link U<7>.
