Abstract: 1,018,508. Ion sources. ATLAS MESSUND ANALYSENTECHNIK G.m.b.H. Oct. 25, 1962 [Oct. 26, 1961; May 23, 1962], No. 40436/62. Heading H1D. In a mass spectrometer, heating of the sample to be ionized is effected by irradiation by a beam of light rays from a source located outside the vacuum chamber of the spectrometer, the rays being produced either by a laser, an ultra-violet source or both. As shown, a sample b to be ionized is arranged in an ionization space provided with electrodes 6, 7 for electron-collision ionization and defined by a casing 5 positioned in a vacuum chamber 1 of a mass spectrometer 2 having an analysing tube 3. Radiation from an external laser 12 reaches the sample b through a lens 13, the intensity of radiation being such that the sample is melted or evaporated. Modifications pertaining to spark discharge and gaseous sample ion sources are described with reference to Figs. 2 and 3 (not shown).

In Fig. 1b, envelopes 13 are fed to an endless conveyer 11, and the label feed rate is synchronized with the article feed rate by a photocell 24<SP>1</SP> detecting an article and causing delivery of a label 22. The wheel speed and conveyer speed are synchronized to provide labelling without slip, and the article feed rate is adjusted relative to the conveyer speed to the optimum for the length of envelope being labelled. The labels may be coated with pressure sensitive adhesive, or may be glued while on the transfer wheel. The wheel operates by vacuum, and its construction is shown expanded in Fig. 2. The rotary part of the wheel consists of the three discs 33, 34, 35 secured together by screws 36. The middle disc has projections 46, 47 which define suction apertures 31, 32 with the adjacent discs. Hub 37 is mounted on and keyed to a motor driven shaft 15, and extends into a static assembly consisting of sector 52 on collar 53, and plate 18 supported by bracket 19. The space within the ring assembly is divided into two chambers by a fixed polyurethane seal 69, and a similar seal 51 on sector 52, and one chamber is connected to vacuum by fitting 64 and pipe 21. The angular extent of this chamber can be varied by rotating sector 52 and seal 51, secured by nut 75, to determine the point on the transfer wheel periphery at which vacuum attraction begins.

Abstract: 1,269,210. Fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 13 Aug., 1969 [29 Aug., 1968], No. 41344/68. Heading G6C. In a fuel element comprising fuel material enclosed in a protective sheath, the fuel material is  divided into longitudinal segments by a plurality of spacer members, one end at least of each spacer member being formed so as to have a low resistance to longitudinal crushing enabling the segments to expand in the longitudinal direction of the sheath by crushing of the corresponding ends of the spacer members. As shown in Fig. 1, a helium filled fuel element, suitable for use in a liquid metal cooled reactor, comprises a stainless steel tubular sheath 2 having end sections 3, 4 of reduced diameter fitted with stainless steel inner sleeves 5, 6 and sealed with end welds 7, 8. Bearing against the inner sleeve 5 is a spigot member 9 connected by a tubular strut 10 with a spigot member 13. The members 9, 13 are sealed by plugs 14, 15 and provided with circlips 16, 17 which locate the strut 10 within the sheath 2. The sheath 2 contains a column of annular fuel pellets 18, e.g. of a UO 2 /PuO 2  mixture, divided into segments 19 by tubular spacer members 20. Each member 20 is of stainless steel and of the same thickness as the sheath 2. A central circumferential recess 21 in each member 20 provides accommodation for braze metal used to fix the member 20 in position in the sheath 2. Each end of every member 20 is formed with petal-shaped extensions 22 which are domed over to form a crushable hemispherical end on the member 20. The other end of the column of fuel pellets 18, remote from the strut 10, is in abutment with a tungsten or molybdenum knit mesh pellet 24 spaced from the inner sleeve 6 by a stainless steel spacer member 25. The spacer members 20 may alternatively have a thick rolled tubular body with a central portion of reduced thickness into which the sheath 2 is crimped. In a further embodiment (Fig. 3, not shown), the spacer members are formed at one end with thin longitudinally extending fingers which are also spaced radially from the internal bore of the sheath. Longitudinal expansion of the fuel material is accommodated by crushing of these fingers.

The electric field around a conductor is controlled by a device comprising a cylindricallybored cone 1 of elastic material which is axially symmetrical, supporting a shielding cone which consists of an electrically-conductive homogeneous layer 2 fitted onto a part of the outer surface 3 of the supporting cone. The conductive layer may be formed from a rubber solution containing 30-60% of graphite laid between the outer surface of the supporting cone and a further closing member 5 of insulating material, or may be formed by a conductive wall layer of the bore of the closing member 5. The closing member and supporting cone can be joined with either electrically non-conductive or conductive glue, the conductive glue forming the shielding cone, or can be joined by vulcanization. The shielding cone 2 may be electrically connected to a shielding layer of the conductor by lengthening the closing member 5 and providing it with a cylindrical bore lined with a ductile material, which bore forms a continuation of the bore 4 of the supporting cone.

Abstract: 1340630 Multiplex radio signalling BLAUPUNKT-WERKE GmbH 14 Sept 1972 [14 Sept 1971] 42646/72 Heading H4L In a system for transmitting TV signals ineluding selectively twin channel or stereophonic audio signals, the twin channel or stereophonic signals are each transmitted on two carrier frequencies, the difference between said carrier frequencies being arranged to differ for twin channel and stereophonic signals thereby enabling the two types of audio transmission to be distinguished. As described, three modes of operation are available. In the first, one audio carrier is used providing a conventional monophonic audio signal. The second uses two audio carriers providing different programmes, e.g. simultaneous broadcasts in two languages. In the third, one audio carrier is modulated with the L + R signal and the other with the L - R signal of a stereophonic signal. This mode may be adapted for quadraphonic transmission. One carrier is fixed at the normal audio carrier frequency of a conventional TV system and the other is arranged to be this frequency plus an odd multiple of half the line-scan frequency. In the example given the fixed carrier frequency is 5À5 MHz and the other carrier frequency is 5À743 MHz for twin channel or 5À759 MHz for stereophonic operation. The receiver includes audio demodulators 1 and 2 tuned to 5À5 MHz and 5À75 MHz respectively, the limited outputs of these demodulators being supplied to a demodulator 3 tuned to a centre frequency of 250 KHz. The outputs of modulators 1 and 2 are also supplied to a matrix 4, for combining the sum and difference stereophonic signals, which is controlled by the output of demodulator 3. In single channel operation only demodulator 1 is operative, there is no output from demodulator 3 and the single channel is supplied to the sum input of the matrix. For twin channel operation the demodulator 3 provides a negative switching voltage and for stereophonic operation a positive voltage whereby the matrix 4 is controlled accordingly. A switch 8 enables a desired one of the twin channel signals to be selected.
