Abstract: 941,491. Internal shoe-drum brakes. GIRLING Ltd. Feb. 22, 1962 [Nov. 23, 1960 (2); May 12, 1961], Nos. 40221/60, 40222/60 and 17364/61. Heading F2E. An adjuster for internal shoe-drum brakes in which one end 15, Fig. 1, of a shoe is engaged by an actuator, e.g. piston-cylinder device 13, and the other end of the shoe is in sliding and rocking engagement with a stationary fulcrum or abutment 16 comprises means mounted on a stationary back plate 14 for engagement with a shoe adjacent to its actuated end and acting on the shoe in a direction substantially parallel to the direction in which the shoe end 15 is moved by the actuator. In one embodiment, Figs. 1 and 2 a cam 19 mounted on a spindle 18 bears on an abutment 21 on the back plate and is held in frictional engagement therewith by a spring 23 so that on rotation of the spindle 18 by means of the squared end thereof the engagement of the cam 19 with the abutment 21 causes the spindle 18 to move outwardly along a slot 22 in the back-plate. In another embodiment, Fig. 5, an eccentric pin 36 mounted on a spindle 35 works in a longitudinal slot in a lever pivoted on the back plate and held in engagement therewith by a spring 38, so that on rotation of the shaft 35 by means of the squared end 42 the pin 36 causes the lever to pivot and move the shoe outwardly through the engagement of the cranked end 33 of the lever with a slot 34 in the shoe. In a further embodiment, Fig. 7, a pearshaped lever 51 having a finger 53 abutting a surface 54 on the shoe is moved about a pivot 52 by the engagement of a snail cam 57, mounted on a shaft 55 which has its outer end squared, with a peg 58 on the lever.

Title: Reading device for monochromator
IPC: G01J3/02
Filed: 1975-10-02
Abstract: 1528933 Reading mono-chromator settings POLSKA AKADEMIA NAUK INSTYTUT CHEMII FIZYCZNEJ 2 Oct 1975 [8 Oct 1974] 40257/75 Heading G2J In a mono-chromator whose wavelength/wavenumber scale 2 is coupled with a mechanism for displacing the spectrum with respect to the exit slit, a transparent plate 9 is arranged to overly the scale 2 and to be moveable in its own plane in a direction normal to scale 2 at the point where readings are taken. The movement of plate 9 is coupled to the slit width adjustment means. Engraved on the plate 9 are several sets of pairs of curves a-f; b-e; c-d. The light passed via the exit slit is a narrow band rather than a single wavelength, and the central wavelength of the band is present with greater intensity (say 100%). Lines a and f intersect the wavelength/wavenumber scale 2 at points corresponding to wavelengths transmitted at the edges of the slit at only 5% of the energy they would show if they were at the centre of the slit. Likewise lines b and e show wavelengths of whose energy only 50% is transmitted by the slit. Lines c and d correspond to 95% transmission. Plate 9 moves to compensate when the slit width is adjusted. Above the point at which readings are taken a beam-splitter 24 directs some of the light via lens 25 and mask 26 to photo-detector 27. The mask is in the focal plane of the lens and is of such width that it is just obscured by the image of one of the graduation lines of the scale 2 (not the spacing between graduation lines). Thus when the scale moves the detector 27 will register the graduation lines as pulses as their images pass the mask aperture. If the spacing of the graduations on scale 2 is non linear, a linear plot may be obtained by known means using the output of the photo-detector. The assembly 23-27 may be moved to focus only portions of short graduation lines only portions of long graduation lines on the mask.

Filed: 1969-08-14
Abstract: 1278827 Automatic focusing control SOC ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE 14 Aug 1969 [14 Aug 1968] 40685/69 Heading G3R A primary electron beam is maintained focused on a metallic workpiece by collecting secondary radiation, converting the collected radiation into a current, and servo-controlling the beam focusing device to minimize the current. In the embodiment shown in Fig.5, electrons from a source 33 are directed on to a workpiece 41 and secondary radiation is detected by an annular plate 27 which is connected through a servo-control device 28 to the main beam focusing coils 31. The secondary radiation consists of three components, viz. high-energy electrons, low-energy electrons and positive ions. While it is stated that all these components have a flux minimum when the beam is correctly focused on the workpiece, the minimum in the high-energy electron flux is the simplest to work with since it is not complicated by adjacent maxima, Figs.6a- 6c (not shown). For this reason, the other components are removed from the secondary beam by appropriately biased conical elements 35, 38. In operation, the system may be used for seam welding, and the length of the beam path may change as the workpiece 41 is moved. The arrangement then acts to adjust the focusing coils 31 and maintain the beam correctly focused. In a further embodiment, Fig.11 (not shown), two systems as shown in Fig.5 are used to control the melting of a metal bar and the presence of a pool of molten metal in a mould. The electron beam is focused partly on the bar and partly on the pool, and the systems operate to ensure a satisfactory ratio between the energies received in each case.

Abstract: 1509410 Automatic control of atmospheric charge BURLINGTON INDUSTRIES Inc 14 Oct 1975 [18 Oct 1974] 41983/75 Heading G3R [Also in Division H1] Air is pumped into a controlled area through a pair of spaced grids to which are applied voltages of opposite polarity and of magnitudes determined by the output of an electric field sensor located in the area, so that the atmosphere in the area is maintained electrically neutral or at a desired charge level. As shown in Fig. 4 air is supplied to a textile mill through an air conditioning duct 30 containing a pair of wire grids 20, 22, Figs. 1-3 (not shown). The mill atmosphere requires a supply of positive ions to keep it at a constant charge level, and accordingly the first grid 20 is held at a negative voltage while the second grid 22 is held positive. The magnitudes of the potentials applied to the grids are determined by the conductivity of transistors 106, 162 controlled by the output from a field sensor 100 located in the mill. The sensor 100 may be a known type producing an ion cloud around a metallic probe, the cloud producing a signal by interaction with the electric field being sensed.
