[Also in Divisions Gl and G2] A spectrometer adaptable to dispersive elements having various focussing characteristics comprises a rectilinear track 17, Fig. 2, mounted on an arm 11 for rotation about an axis O perpendicular to the track 17 and the centre of the grating G coinciding with the axis O. A radiation receiver D and entrance slit S are slidable along track 17 on a carriage 10 by means of a pinion 16 connected to an electric servomotor 15, and the arm 11 is rotated about axis O by an electric servomotor 24 rotating gears 26, 27 and 28 controlling a screw 22 which bears through plate 21 on a roller 20 on arm 11. Movement is controlled by two potentiometers 32 and 33 connected up in a circuit as shown, Fig. 3, a change in the setting of either. will cause a voltage to be applied to servomotor 15 so as to drive the carriage 10 along track 17 also causing feedback potentiometer 19 to be rotated. Motion will continue till the two input voltages in the differential amplifier 30 are equal. By varying potentiometer 33, potentiometer 37 is also varied so causing servomotor 24 to operate and hence rotate arm 11 and feed back potentiometer 29 till the voltage inputs to the differential amplifier 35 are equal. So rotating knob 42 will cause slit S to traverse a circular path, the radius of the path being controlled by knob 39. The angle of incidence can be varied by mounting the whole of the mechanism described on a further carriage (not shown) so that it is rotatable as a whole relative to the further carriage about the axis of shaft 12, the further carriagesbeing movable along a fixed rectilinear track. The necessary related movements may be brought about by an arrangement similarto that used for moving the detector. A further embodiment which provides rotation and translation of the detector and rotation and translation of the grating is similar to that previously described except that the grating can be rotated synchronously with the detector track or the detector track can be rotated separately. This rotation is carried out with the aid of five gears arranged in a V shape with the central gear supporting the grating, the drive mechanism being substantially similar to that previously described.

Abstract: 1,173,919. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 7 Dec., 1966 [30 Dec., 1965], No. 54713/66. Heading H1K. " Hot " electrons are emitted, under the action of an applied potential 13, from one of two non-rectifying contacts 5, 6 on a semi-conducting region 2, the electrons passing through a PN junction 14 into a semi-conducting region 3 of opposite conductivity type to that of the region 2. A further non-rectifying contact 11 is provided on the region 3, and a potential 12 is applied across the contacts 5, 11 to bias the junction 14. As shown the junction 14 is reversebiased, and the contacts 5, 6 are formed by alloying or diffusing N-type zones into the N + - type region 2, which is itself formed by diffusion through an etched oxide mask 4, e.g. of SiO 2 . The region 2 is preferably less than 1 Á thick, and may also be formed by epitaxy. Conducting paths 9, 10 are then applied to the zones 5, 6. In a second embodiment the junction is forward-biased, and the contacts 5, 6 comprise N + -type zones within an N-type region 2. In both embodiments the contact 11 is formed by a P+-zone in the P-type region 3. A number of such devices may be formed on a common P-type substrate, with the conducting paths 9, 10 linking the contacts 5, 6 in series. The contacts 5, 6 may be arranged interdigitally on the semi-conducting region 2. P-type contacts may also be used in P + -type material, and in this case the semi-conductor material of the contact may differ from that of the P + -type region. Suitable semi-conductor materials include germanium, silicon, III/V or II/VI compounds, ionic semi-conductors or organic semi-conductors. The voltage applied to the contacts 5, 6 may be direct and/or alternating and is less than double the Peltier voltage between the zones 5, 6 and the region 2. The voltage across the junction 14 is at most equal to the breakdown voltage of the junction. The invention may be applied to multi-junction devices, and may be used in integrated circuits or micro-wave circuits.

As shown, the slot is defined by two rods 6 and the means 13 is a spring. Each end of the pin 8 engages in a notch in a spring 13 and each spring has a projection which engages an edge of an aperture 11 to hold the pin in belt gripping position. To release the belt projecting knobs 12 on the ends of the pin are moved away from the slot and the projection moves to the outer surface of the frame. Various spring means for urging the pin into gripping position are described. The spring may be a bent spring leaf, a helical coil or an arm carrying a tooth integral with a knob. The knob may have a spring urged downwardly extending tooth. Two blade springs may be bent inwardly or outwardly of the frame, anchored at one end to the pin and slidable in slots or fixed to the frame at the other end. The springs are then pressed inwardly to release the pin. The pin may have two members spring urged outwardly of the frame and with tapered surfaces which engage the edge of an aperture to effect belt gripping. The members are moved inwardly to release the grip on the belt. Instead of using a spring the rolls 6 and the pin 8 are made of ferromagnetic materials and one member is magnetised Fig. 25 (not shown). The pin may be held in gripping position by a spring urged pivoted cam. The buckle frame may have portions projecting to each side of the pin knobs or spring means to prevent inadvertent operation thereof.

Abstract: 1,173,749. Colour television. FERNSEH G.m.b.H. 21 Dec., 1966 [30 Dec., 1965], No. 57244/66. Heading H4F. The two colour-difference components of a PAL colour television system which are applied to the (orthogonal) deflection plates of a vector oscilloscope are suppressed for the duration of every second line scan. Thus by exhibiting a selected one only of the two phases of the phase alternating component, the R-Y component, the complexity of the display is reduced from that produced by known arrangements (Fig. 1) to that shown in Fig. 2. In carrying out the invention, the gate 8 (Fig. 3), through which the colour modulated carrier is supplied to the oscilloscope via synchronous demodulators 6, 7 low-pass filters 4, 5 and amplifiers 2, 3 is closed during alternate line scans by means of a pulse train from a polarity reverser 11, the train 24 (switch 21 in full line position) closing it during the positive phase of the R-Y component and train 24<SP>1</SP> (switch 21 in clotted line position) closing it during the negative phase. When the positive phase is gated out (suppressed) the same scale (as shown in Fig. 1) associated with conventional displays (i.e. of both phases) may be utilized as shown in Fig. 2. However, when it is desired to display the negative phase of the R-Y component alone switch 21 is placed in the dotted line position and with a switch 22 in the dotted line position the pulse train 24 (of onehalf line frequency) operates a phase-switch 12 which reverses, during alternate lines, the phase of the demodulating colour carrier from generator 18 which is supplied to the R-Y synchronous demodulator 7 so that the negative phase relationship is reversed and the existing scale can still be employed.
