Title: Improvements in or relating to radiation-therapy
IPC: G21K5/10
Filed: 1935-06-15
Abstract: 458,677. Radiation and electric therapy apparatus. BAUCH, F. W. O., 23, Althoffstrasse, Steglitz, Berlin. June 15, 1935, No. 17329. [Class 81 (ii)] [See also Group XX] Apparatus for treating a particular part of the body with radiations or oscillating electric fields whilst leaving adjacent parts substantially untreated, is characterized in that a beam of radiation, or an electric field projected through the part is rotated about an axis also passing through the part and at an angle to the beam such that the beam moves over a conical surface. As shown a R÷ntgen-ray tube 11, projecting a beam via a screen 15 through the part 14 to be treated, is rotated about an axis x, y; the beam consequently passes constantly through the port 14 but only intermittently through adjacent ports. Reflecting or refracting means may be used to rotate beams responding to such means ; for example a beam directed through the part 14 may be so reflected from a pair of mirrors as to pass through the part at an angle to the original axis of the beam, the mirrors being rotated as a unit about such original axis. In an electric oscillating circuit comprising inductance, and a pair of condenser plates on opposite sides of the body, the condenser plates may be mounted on conducting arms to rotate about an axis at an angle to their mutual axis, both axes passing through the part to be treated. Reference has been directed by the Comptroller to Specification 369,662, [Group XX].

Title: Anti-theft lock
IPC: B60R25/021
Filed: 1963-05-02
Abstract: 1,022,858. Locks. A. NEIMAN. May 2, 1963 [May 3, 1962; April 4, 1963], No. 17364/63. Heading E2A. [Also in Division F1] A vehicle anti-theft lock comprises a casing 9, Fig. 3, a rotatable cylinder 10 arranged within the casing and adapted to receive a key 11 by which the cylinder is rotated, a contactor plate 19 connected to the cylinder for rotation relative to fixed terminals, a spring urged bolt 15 movable within the casing and engageable with an aperture in a part to be locked, a spring urged locking element for the bolt, movable into positions where the bolt is free to move and where the element engages the bolt or an extension thereof to lock the bolt, either in a position in which the part referred to is unlocked or in a position in which the part is locked. As shown, the key 11 is provided with a notch 11a into which a plate 23a constituting the locking element is urged when the key is completely engaged in the lock. A plate 26, Fig. 8 (not shown), attached to the bolt 15 is formed with notches 26a, 26b and a cam follower 26c which cooperates with a cam 18a on a rotor 18, Fig. 3, carrying the contactor plate 19. The arrangement is such that while the key 11 is in the lock, the plate 23a is held in a first position by the notch 11a of the key 11 in engagement with notch 26a and prevents the bolt 15 from moving from an unlocked retracted position to a locked projected position. As the key is withdrawn, the plate 23a engages a part 11b of the key and releases the bolt 15 towards it projected position and upon complete withdrawal of the key the plate 23a engages notch 26b to lock the bolt in its projected "stop" position. When the key 11 is inserted and turned, the bolt is retracted, the plate 23a is disengaged from the notch 11a and slides on an arcuate surface of the cylinder 10 to allow removal of the key. The lock is then in a "garage" position. In the arrangement according to Figs 11-17 (not shown), a lock cylinder includes a collar which connects with a cam, a stem of which extends across a bolt and engages a case housing a torsion spring, adapted to disconnect the vehicle starting switch when the lock key is released and while the end of the stem is engaged in a rotor of an electrical contact. A groove on the lock casing houses a spring-loaded lever a part of which engages a notch of the key. In this position the bolt is held retracted. As the key is withdrawn, the bolt is released to the "stop" position and the lever engages a notch on the bolt. When the key is inserted and turned, the cam withdraws the bolt and another part of the lever re-engages a further notch on the bolt.

Abstract: 1,031,177. Packaging machines. CHESEBROUGH-PONDS Inc. May 6, 1963. No. 17853/63. Heading B8C. [Also in Division A5] Soft fibrous material is applied to one or both ends of a stick whilst it is being twirled (see Division A5) and the resulting swabs are then boxed. The packaging operation is performed by a toothed carrier comb 263, Fig. 43, that moves from the position shown in Fig. 43 to that shown in Fig. 44 to engage a predetermined number of sticks carried by the accumulator wheels 17 and to push them outwardly from the grooves 18 against the yielding guides 258. The comb then swings downwardly, Figs. 45 and 46 (not shown), to deposit the group of sticks in a carton 19 at the filling station. The comb 263 immediately swings back to the position shown in Fig. 43 to engage another group of sticks assembled under the guides 258 when the foremost swab actuates a microswitch 330, Fig. 39 (not shown). The operations are then repeated until the carton 19 is filled with a predetermined number of layers. The cartons 19 are carried by a rotary table 262 that is loaded manually. The comb 263 comprises a plate from which project three rows of teeth 264, Fig. 49 (not shown), one row on each side and one at the centre. The individual teeth of the centre row are slightly out of line with the corresponding teeth of the two side rows so that the sticks 4 of the swabs are bent slightly in order to give the teeth a secure grip on the swab sticks. When the comb 263 has swung downwardly to the position shown in Fig. 46, two stripper plates 334 and 334a (334a is not shown in Fig. 46) descend to strip the sticks 4 from the comb. In Fig. 46 two layers 335 and 336 have been inserted in the carton. As each layer is inserted the operator places a separator 337 of cardboard or the like on top of the deposited layer.

Abstract: 402,013. Type - making machines. MONOTYPE CORPORATION, Ltd., 43, Fetter Lane, London, and PIERPONT, F. H., Oakfield, Redhill, Surrey. June 28, 1933, No. 18371. [Class 100 (iii).] Single-type composing and casting machines; moulds.-The low-quad casting-mechanism described in Specification 22303/13, [Class 100 (iii), Type making &c.], is modified so as to permit of lateral adjustment of the centring-pin being made when required. The controlling- lever N, Fig. 1, of the cut-off blade is, as heretofore, engaged between two levers M M<1>, one or the other of which is rocked by a lever B, pivoted on an arm O of the centring-lever J. According to the invention, the lover B is operated by a lever A, which is pivoted on the arm O and is connected to the centring-pin D by a pin A<2>, Fig. 2, which engages in a slotted bearing c on the lower head C of the centring- pin. The centring-pin can thus be adjusted without disconnecting it from the lever A. When the centring-pin is arrested by a low-quad matrix, a cam-face on the lever A remains in the path of the lever B, which, during its descent, is rocked against the action of a spring B<2>, and causes the operation of the cut-off blade. The full descent of the centring-pin permitted by a normal matrix removes the cam-face on the lever A from the path of the lever B. The head C on the centring-pin is prevented from rotating accidentally by a fork C<1>, which engages a post P. Specification 8633/99, [Class 100, Printing, Letterpress &c.], also is referred to.

A book is inserted as shown and a coin, photograph, watch, &c. 34 is inserted in a pocket 42 and closed by a sliding-clasp fastener 31. On examination in the latter condition, the object 34 cannot be observed. If now the book is removed, the "magician" can observe the object through the louvred layer 40 interposed between transparent sheets 36, 38. The layer 40 comprises cellulose acetate butyrate or polycarbonate film having slits therein filled with an opaque material. The other side of the wallet contains an opaque sheet 40A, so that when the object is switched into the pocket 44 it cannot be perceived in any manner. This pocket is thus used to contain the object so that an "audience" can inspect the wallet without perceiving the secret.

Title: Improvements in paper and the like embossing presses
IPC: B31F1/07
Filed: 1928-06-27
Abstract: 306,353. Thornton, E. R. E. June 27, 1928. Embossing. - A press for embossing paper or the like, and colouring the raised parts of the embossing, comprises a male die 19 fixed to a base 4, and a female die 6 and colourapplying surface 8 mounted on a member 5 which is reciprocated to bring the die 6 and surface 8 alternately over the die 19, amd is depressed in these positions so as to emboss and colour the paper. The member 5 is slotted at 6' to engage a pivot rod 30 on the frame 3 of the machine, and so reciprocated by means of a handle 1 connnected by a link 28 to a lever 13 attached by two springs 15, 16 to pins 17, 18 respectively on the member 5, the pin 30 serving to limit the to-and-fro movement. Projecting corners 11, 12 on the lever 1 engage the upper surface of the member 5, so that when the handle 1 is turned in a clockwise direction, Fig. 1, the die 6 is forced downwardly against the action of a spring 9 to emboss the paper, and when the direction of turning is reversed, the die 6 is raised, the member 5 moved to bring the surface 8 over the die 19, and the corner 12 comes into action to depress the surface 8 into socket contact with the paper. The surface 8 is carried by a crossbar 7 on the member, and is depressed into contact with an ink-pad 21 in the base 4, at the same time as the die 6 performs the embossing operation. The surface 8 may be of the same form as the die 19 so as to ensure that only the raised parts of the paper are coloured, and may be made of the same size as the pad 21 and kept depressed thereon by a clip during the inspection of the press, so as to keep the pad clean and prevent evaporation. In a modification, the pad 21 may be dispensed with, and the surface 8 made self-inking. Screws 29 threaded through the bar 7 have enlarged ends 32 adapted to engage the base 4 so as to limit the downward movement of the member 5 and prevent the surface 8 from being pressed too far into the embossed paper. A device for holding the paper to be embossed' in position consists of two metal strips 23 secured to the base 4 by screws 25 and interposed springs 26, and joined by a transverse strip, the paper being inserted underneath the strips until its edge abuts against the pad container 21.
