Title: Irradiation apparatus
Inventor: KERJEAN JOEL
IPC: G21K5/02
Filed: 1966-07-26
Abstract: 1,094,423. Irradiation apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 26, 1966 [July 30, 1965], No. 33628/66. Heading H5R. An apparatus for the irradiation of samples comprises a block of radiation absorbing material acting as a biological shield, a chamber formed in the block, a removable container for samples to be irradiated which can be inserted into the chamber and a number of removable radiation sources disposed in rectilinear channels formed in the biological shield said channels extending into the chamber and being distributed at equiangular intervals round an axis of the chamber wherein the channels are arranged so as to generate a hyperboloid of one surface whose axis is the same as that of the chamber and whose narrowed portion occurs opposite the container. Fig. 3 shows an embodiment of the apparatus. It comprises three parts 22, 18 and 20 held in correct relationship by frame 44 which also carries the manipulating means for the removable container. The main section 18 contains the chamber 6 and comprises a radiation absorbent material 8 contained in a sheet metal jacket 26. Around the chamber are arranged ten source channels 12, only one on which is shown for the sake of clarity. The radiation source preferably comprises two active sections, e.g. Co 60 separated by an inactive section, e.g. Al, and in use the source is positioned in channel 12 so that the inactive section is placed directly opposite the sample container. The sample carrying container is formed by a plunger 36 having a central compartment flanked by two protective sections of radiation absorbent material. The container is inserted into and removed from the chamber by means of rack 46 and pinion 48 operated by motor 50. Winch 54 carrying counterweight 52 reduces the force which has to be used. Section 22 of the apparatus provides shielding at the top for the plugs of source channels 12 and is also equipped with pivoted doors 41 and 42 to provide access to the samples when plug 36 is raised. Section 20 is merely a base on which the chamber stands. The biological shielding is supplied with cooling conduit 34, and conduits 28 and 30 provide an air circulation conduit equipped with filter 32 for discharge to atmosphere, so as to prevent an accumulation of ozone in the irradiation chamber.

Title: Improved pencil sharpener and point protector
IPC: B43L23/08
Filed: 1937-12-06
Abstract: 485,911. Pencil sharpeners. FRUH, K. Dec. 6, 1937, No. 33672. [Class 146 (iii)] A combined pencil sharpener and point protector comprises a sharpener portion a which is pivotally connected at p to a slotted tubular portion b which fits on the pencil, and the construction is such that the sharpener portion can be swung clear of the pencil when the latter is to be used. The portion a is conically shaped, provided with a base-plate carrying a cutter c, and is slotted at m<1> to allow it to be swung out of alignment with the portion b. A coil spring on the pivot point p with one leg bearing on the portion b and the other on the portion a tends to bring the two portions into alignment. A slide h pivoted at k to the portion a slides under a guide r on the portion b during the pivotal movement of the portion a, and a stop h<1> on the slide limits the amount of such pivotal movement.

IPC: A24C1/04
Filed: 1962-09-04
Abstract: 946,734. Cigar-making machines. K. KÍRBER. Sept. 4, 1962, No. 33820/62. Heading A2C. Apparatus for punching and feeding cigar wrappers comprises a support 1 rotatable about a horizontal axis and provided with surfaces 4 for co-acting with the material 6 from which the wrappers are punched. The material is fed over a roller 9 between reciprocating rollers 11 and the support 1. The support carries four punch cutters 3 which each surround lifters 13 which are normally held below the level of the cutters by springs 15 but which may be raised above that level by cams 14 on a hollow spindle 2 on which the support 1 is rotatably mounted. During the punching operation the material is held against the vertical surface 4 by suction applied through one end of the spindle 2 and the slot 19 therein to apertures 5 in the surface 4. Suction is also applied to the apertures 5 in the lifter 13 through a slot 18 in the vertical lifter 13 and corresponding slot 17 in the spindle 2. After cutting, the support 1 rotates through 90 degrees and the surface 4 attains a horizontal position in which compressed air passes through the other end of spindle 2, slot 17 and corresponding slot 16 in the horizontal lifter 13.

Abstract: 618,987. Controlling change-speed gears ; clutches. BORG & BECK CO., Ltd. Nov. 15, 1946, No. 33998. Convention date, Oct. 20, 1945. [Class 80 (ii)] A centrifugally engaged friction clutch driving a change-speed gear has means to produce a driving drag when the centrifugal engaging mechanism is inoperative, the drag producing means being inoperative when the change-speed gear is in the neutral position. A centrifugally engaged clutch comprises a driving flywheel 10, a pressure plate 20 moved by the action of the flyweights 36, and a driven disc 18 whose hub 18a is splined to the driven shaft E. The hub 18a is urged towards the engaging position to provide a driving drag by a spring 46 abutting between the washers 44 and 48, the latter being recessed into the shaft E. Two sleeves 12, 50 are carried by the shaft E, the sleeve 50 being increased in diameter at its forward end to house a spring ring 54, a spring 56 being interposed between the end of the sleeve 12 and the sleeve 50 to normally hold the ring 54 clear of the washer 44. The ring 54 is moved rearwards to release the drag by a lever 60 pivoted at 61 on the edge of a slot in the inner sleeve 50. The lever is moved by a solenoid 62 energized by a battery 70 when the synchronizer cone D of the gear-box is in the neutral position. In a modification the solenoid is replaced by a bell-crank lever moved by an enlargement on the gear selector rod, when the latter is in the neutral position.

Abstract: 1,196,996. Boots &c. T. FUKUOKA. 20 July, 1968, No. 34753/68. Heading A3B. A sandal comprises a sole member 2 and a band member 1 which are integrally and simultaneously molded of synthetic resin and which have a foamed interior portion 3 and a solid outer layer 10. The upper surface of the sole member 2 is shaped to conform to the sole of the wearer's foot and has a transverse ridge 11, a shallow concave depression 4 and a deeper concave depression 5. The sandal is made by injecting the synthetic resin, containing a blowing agent, in a hot fluid condition into a mould under sufficient pressure to prevent foaming. The mould is cooled so that the solid outer layer 10 is formed and has a mould cavity which can be enlarged to relieve the pressure of the synthetic resin thus allowing the blowing agent to form the foamed interior portion 3. Suitable synthetic resins are polymers and copolymers of styrene and styrene derivatives, copolymers of vinylidene chloride, polymers and copolymers of methyl methacrylate, ethyl acrylate and other derivatives of acrylic acid, polymers and copolymers of vinyl acetate and vinyl butyral, and various cellulose derivatives including cellulose nitrate or acetate.

Abstract: 644,625. Thermal switches. BESSET, M. Dec. 31, 1947, No. 35141. Convention date, Oct. 2, 1946. [Class 38(v)] [Also in Group XXXVIII] A thermally-actuated timing switch arrangement for controlling traffic indicators, comprises contact blades 1, 2 conected in the indicator circuit to be controlled and held open by a projection 3 on a lever 4, which is normally held in the position shown against the tension of a spring 6 by a wire 7. When a manually operated push-button switch 14 is held closed for a short time, the wire 7 is heated and expands, so that the spring 6 moves the lever in the direction of the arrow f and the contacts 1, 2 are closed. On the release of the switch 14 the wire 7 cools allowing the re-opening of the contacts 1, 2 after a short time interval. To prevent damage of the wire 7 due to overheating, should the switch 14 be held closed for too long a period, contact blades 11, 12 in series with the wire 7 are provided. Both blades move with the lever 4 and when the wire has lengthened to a predetermined extent, the blade 11 is arrested by an abutment 15, and the circuit through the wire 7 opened.
