Title: Dialling signal transmission system
IPC: H04Q1/38
Filed: 1973-09-20
Abstract: 1423668 Automatic exchange systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 20 Sept 1973 [21 Sept 1972] 44252/73 Heading H4K In a dialling signal transmission system the transmitter includes a keyboard-Fig. 1- which is operative to insert in the transmission line at least one semi-conductor element capable of providing a distinct voltage level for each direction of line current, and a receiver-Fig. 3- which receives the line voltage levels before and after current reversal and stores these values. Transmitter.-Each key except 9 controls two crossed bars, 9 controlling its separate bar. When the line is looped, subsequent depression of a key causes one or more Zener diodes Z1- 25 or diodes D1-D3 to be introduced into the line. In one line current direction there are three voltage levels available for the keys, in the other direction four levels (including zero). Hence a depressed key is uniquely determined by the two voltage levels it produces in the looped line, one for each current direction. The receiver at an exchange includes two groups each of three bi-stable elements AMCM and DM-FM. Looping the line clears the first group, which then receives and stores the first voltage level produced by a key depression. As soon as this first level is stored, a control signal is produced to reverse the line current direction. The second voltage level is then determined, the dialled digit is thereby recognized, and the receiver is re-set to receive the next digit.

[Also in Division G4] Apparatus for mounting a fluorescent lamp (see Division G4) comprises a transistor 23, normally biased to be conducting, to the base of which is applied a direct voltage derived from rectifying the alternating voltage produced in an auxiliary winding 20 on transformer 13. When the lamp 10 is struck, the voltage on winding 20 is insufficient to overcome the bias applied by Zener diode 28, and diode 21 is non- conducting so that transistor 23 is forward biased. If lamp 10 is not struck, the voltage on winding 20 is insufficient to overcome the bias of the Zener diode and transistor 23 is cut off. In an alternative embodiment, Fig. 2 (not shown), the auxiliary winding is on the ballast choke 14 and the voltage developed is rectified and used to forward or reverse bias a diode in the transistor base circuit.

Title: Improved mower with grass catcher
IPC: A01D34/42
Filed: 1968-09-19
Abstract: 1,237,590. Grass-catcher. TORO MFG. CORP. 19 Sept., 1968, No. 44679/68. Heading A1F. [Also in Division B7] A lawn mower having a grass-catcher mounted at the front is arranged so that the spillage of clippings from the catcher when the mower is tilted is minimised. The catcher 10 is positioned between the arms of a fork 50 attached to the mower frame 40. The only direct means of support between the catcher 10 and the frame 40 is provided by the pins 18, attached to the sides of the catcher, which engage the brackets 51 attached to the fork 50. The leading end of the catcher 10 is supported by a roller 12, and the catcher has recesses for the rollers 43, 44 supporting the front end of the mower. When the mower is tilted about the barrel-shaped traction rollers 41, the catcher 10 is arranged to contact and pivot about the roller 44, and assume a position as shown in Fig. 3. As the catcher takes up its new position, the pins 18, originally held by the arms 51A of the brackets 51, move forward and rest against the arms 51B. In this position, the catcher 10 is much less likely to spill the clippings, and in addition, the forward movement jolts the clippings further into the catcher, thereby increasing its effective capacity. The handle of the mower includes a front panel 30 containing a slot which engages with any of the notches of the latch 33 to vary the angle of the handle. A drive shaft extends laterally from the transmission case 40 and drives the cutter reel 39 by means of a chain housed in the cover 42. Mounting plates 45 extend forwardly from opposite ends of the cutter assembly and contain a bed-knife adjustment assembly 46 and means for adjusting the height of cut 47. A pull-arm assembly 48 extends between and interconnects the rollers 43 and 44, and another roller 49 is mounted at the rear of the plates 45 to maintain the cutter assembly above the ground.

Abstract: 998,147. Classifying pulses. VAKUTRONIK VEB. Nov. 28, 1962, No. 45023/62. Heading H3P. A pulse amplitude analyser comprises lower and upper level discriminators 2, 3 the outputs of which respectively set and reset a bi-stable circuit 6 controlling a gate 8. If a pulse has sufficient amplitude to pass only discriminator 2, the gate 8 is opened by the bi-stable circuit 6 and allows the pulse (after delay at 14) to pass to line 10. The bistable circuit 6 is then reset by a further pulse delayed at 17. If, however, the pulse has sufficient amplitude to pass both discriminators 2, 3 then the gate will be opened and closed before the arrival of the pulse delayed at 14 and no output on line 10 will result. The outputs of discriminators 2, 3 are preferably differentiated at 12, 13. In Fig. 3 (not shown) the resetting pulse is derived by delaying in a damped oscillatory circuit, the pulse from line 10.

Abstract: 973,127. Sound insulation. S. SEDLAK. Dec. 5, 1962 [Dec. 8, 1961], No. 45971/62. Heading F2X. [Also in Divisions B3, G6 and H1] A flexible sheet which may be sound absorbing comprises a matrix made of flexible material, e.g. natural rubber, synthetic rubber, or plastic, containing a number of rigid members of similar shape and size embedded therein in a substantially uniform array, said members being tapered in a direction extending between the faces of the sheet. Preferably the members taper in both directions from the centre of the sheet (see Fig. 2) but the taper may also extend from one face of the sheet towards the other, and the direction of taper of adjacent members may extend in opposite directions or be the same (see Figs. 16 and 18). The members are preferably ellipsoidal but other solids of revolution may be suitable, or the rigid members may also be polygonal bipyramids. The arrangement of rigid members may be square (Fig. 3, not shown) or triangular (Fig. 5, not shown) and the members may be truncated (Fig. 7, not shown) to increase the packing density. When used as a soundabsorbing material, the members are made of a suitable substance e.g. lead or tungsten and in addition lead or tungsten may be added to the matrix composition so as to render the matrix itself sound absorbent. To provide a more homogenous sheet, the gaps in the array of members may be filled with smaller secondary members (see Fig. 9) made of the same material as the larger members, although the arrangements shown in Fig. 16 and that of Fig. 17 with the axes of the ellipsoid inclined achieves the same effect. Flexible materials for different purposes (see Divisions G6 and H1) may be obtained by using different materials for the rigid members. For the method of producing the sheets see Division B3.

Abstract: 1,193,696. Measuring coating thicknesses photo-electrically. LEYBOLD HERAEUSVERWALTUNG G.m.b.H. Oct.11, 1967 [Oct. 13 1966], No. 46490/67. Heading G1A. An instrument for measuring the thickness of a coating on an object as the coating is deposited by vapour position, comprises a light source and a detector each adapted to be mounted in the deposition chamber, and has means for compensating for ambient light within the chamber. As described the instrument is in the form of two separate units each having a ball joint by which they may be mounted in the chamber. One unit comprises the light source and an adjustable lens system for forming the light into a narrow pencil and producing an image of the source at a chosen distance. The detector unit includes two parallel tube members each of which allows a shaft of light arriving along the axis of that tube to fall on the corresponding photo-resistor. The two units are positioned within the chamber such that light from the source impinges on the object being coated and is reflected or transmitted by the coating to the detector unit where it arrives along the axis of one of the tubes of that unit. The other tube of the unit receives only ambient light and the two photo-resistors are connected differentially in a bridge arrangement. The analog output as measured by a galvanometer is a measure of the thickness of the coating. The object being coated may be fixed or a plurality of objects may be located on a table rotated to bring the objects sequentially into the light path. The rate of rotation is such that consecutive objects enter the path about 1/30 th second apart and in consequence the galvanometer gives a smooth reading which does not return to zero between objects. An additional light source in the detector unit irradiates both photo-resistors to bias them to a low resistance, linear part of their characteristic where they respond quickly. A monochromatising filter is located in front of both photo-resistors.
