Abstract: 1454097 Electron microscopes; ion beam tubes SIEMENS AG 7 Sept 1973 [7 Sept 1972] 40134/73 Heading H1D [Also in Division H4F] A corpuscular beam transmission microscope (e.g. electron microscope) includes deflection systems 15, 16 which with control device 17 directs the beam to dwell statically at an object point to be examined and directs the transmitted beam to an image recording or display means and in which after the dwell period the beam follows a path that moves from the point under examination either back to the off-set rest position or to a further point to be examined. Recording may be by photographic plates, electronic picture stores incorporating a TV camera with a storage target, or a long persistence screen monitor. Transmission time may be automatically determined by the control device as a function of intensity via monitor 8 to safeguard the specimen, recording commencing an interval after irradiation command to ensure electrostatic charging of the object is eliminated. The beam may dwell in succession at a series of different points, focusing having been effected on a separate object point. When photoplate 7 is removed the final image is on fibre optic system 11 coupled to TV camera 10 via amplifier 12, and coupled to display store 13 and monitor 14.

Title: Gas-tight closure for containers
IPC: G21F5/12
Filed: 1971-09-08
Abstract: 1319208 Glove boxes GESELLSCHAFT FUER KERNFORSCHUNG mbH and H R SCHRADER 8 Sept 1971 [26 Sept 1970] 41848/71 Heading B4Q An arrangement for transferring substances between a vessel 1 closed by a cover 11 and a glove box 3 having a flange 2 closed by a cover 8 similar to that described in Specification 1,270,069 differs in that the pin 19 in this case co-operates with a nut 35 fixed to a locking cross 14 comprising two or more cross arms having T or double T cross-sections. In order to close the vessel 1 and render it gas-tight, or to open the vessel, the cover 11 and the locking cross 14 are arranged either with a small clearance (shown on right-hand side) or with a larger clearance (shown on left-hand side) between them. The free ends of the locking cross 14 are provided with locking pins 15 which pivot about axes 13 on displacement of the locking cross 14. In one end position of the latter (closing position), the tips of the locking pins 15 engage firmly and undisplaceably in the groove 20 countersunk in the inner wall of the vessel 1, whereupon the cover 11 is firmly pressed against the seal 10 and the vessel 1 is tightly closed. In the second end position of the locking cross 14, the locking pins 15 are in a position enabling the cover 11 and cross 14 to rise from the front of the vessel 1. This is achieved by the lower side of the cover 11 being provided with eyelets 17, the bottom portions 37 of which form stops for the locking pins 15. Other abutment eyelets 38 are secured to the underside of the cover 11, the bottom portions 39 of these retarding the arms of the locking cross 14 in their movement away from the cover 11. The bottom portions 37 of the eyelets 17 extend through slots 40 in the locking pins 15 and guide the pivotal movements of th pins during the reciprocating motion of the locking cross 14. The reciprocating motion is effected by means of the spindle 22, spring-loaded coupling 33 and coupling part 18 as in the abovementioned Specification. This locking method makes it possible to lock vessels of larger diameter, since the arms of the cross 14 and the locking pins 15 can be of considerable rigidity.

Title: Improvements in or relating to level-control arrangements
IPC: H04B3/12
Filed: 1959-12-09
Abstract: 916,252. Automatic volume control. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 9, 1959 [Dec. 12, 1958], No. 41877/59. Class 40 (4). In a pilot-controlled system in which the pilot current is extracted from the output of a variable gain amplifier and used to control a thermistor whose impedance controls the gain of the amplifier, the thermistor is contained in a transistor amplifier circuit so arranged as to protect the thermistor from excessive variations in current. As shown, the pilot is accepted by the filter 3, amplified at 4, rectified at 5 and smoothed at 6 and thence applied to the base of transistor 10 acting as a current amplifier. With transistor 11 normally drawing heavy current the full rectifier output is applied to the thermistor 9 whose variations in resistance are reflected by the transformer 15 into the loss network 8 in the negative feed-back circuit of amplifier 2, to vary the gain of the amplifier. If the pilot level falls excessively, transistor 10 cuts off, but some current is maintained through the thermistor via resistances 12<SP>1</SP>, 12 and 14. If the pilot level rises excessively, the collector current for transistor 10 in passing through resistor 12<SP>1</SP> moves the base potential of the transistor 11 nearer to earth, whereby some of the rectifier output is dropped across its collector-emitter circuit so protecting the thermistor. In a modification, Fig. 1 (not shown), the resistor 21 is reduced in value and connected to the upper terminal of the thermistor instead of earth.

Abstract: 1,163,437. Seaming non-metallic sheet material. W. BAHLSEN. 23 Sept., 1966 [15 Oct., 1965], No. 42468/66. Heading B5K. Surfaces are bonded together by applying a melt adhesive to at least one of the surfaces, conducting additional heat to the bonding position during the application of the melt adhesive, and then bringing the surfaces into contact. By melt adhesive is meant an adhesive material comprising a plastics material and a wax component. The plastics material may be a polyvinyl resin, such as polyvinylacetate, polyvinylisobutylether or an acid vinyl ester, or polyethylene or polypropylene. The wax component may be a paraffin, a natural wax such as carnuba wax, a synthetic resin or a derivative of a natural resin such as colophonium or fusible polyamides. In one embodiment, Fig. 1 (not shown), the knife edge of a chisel-shaped tool is provided with a layer of melt adhesive by dipping the tool into a reservoir of the adhesive. The tool is heated by internal electrical heating elements or by passing heating media therethrough. The tool is introduced into the mouth of a filled bag so that the adhesive layer contacts the walls of the bag mouth and on removal of the tool this layer remains stuck to the walls to form a seal. In a further embodiment, Fig. 2, the adhesive is applied by a tool 4 provided with slits 5, 6 which, after the tool has been dipped in the melt adhesive, retain adhesive therein by capillary attraction until the tool contacts one or both surfaces to be bonded and the adhesive is released. Instead of the slits 5, 6, tubes, grooves or other indentations may be formed in the tool 4 to produce the capillary effect. The tool 4 is used to seal a flap 8 to an underlying flap 9 of a folding box 7. The tool 4 is heated either electrically or by circulation of a fluid therethrough. In a modification, the adhesive is fed through the inside of the tool 4, e.g. through a passage in a support 10 and through tubes 11, 12 into the slits 5, 6. In another embodiment, Fig. 3, a tool 13, formed similarly to the tool 4, is moved continuously in the direction of the arrow 14 over a layer 15. Slight pressure is applied at 17 to a second layer 16 to continuously bond the layers together. In a still further embodiment, Fig. 6 (not shown), the melt adhesive is applied to a reciprocating chisel-shaped heated tool by contact of the tool with a roller rotating in a bath of the adhesive. In yet another embodiment, Fig. 7, the tool is in the form of a wheel 32 continuously rotating in a melt adhesive bath 33 and bonds a flap 36 on a lid 34 to a box body 35. The wheel 32 may be heated by a heated hub 37.
