Abstract: 1,228,889. Sensing icing conditions electrically. FINDLAY IRVINE Ltd. Oct.6, 1969 [Oct. 10, 1968], No.48148/68. Heading G1N. The change in collector current of a transistor 10 with temperature, used to measure the temperature of a road surface, operates a controller 16 at freezing point when the surface is dry, but at a lower temperature when the surface is wet and has been salted. The latter condition reduces the resistance between surface electrodes 18, 19 to trigger a bi-stable circuit 37 at a predetermined salt concentration and varies the bias on the base of transistor 10 so that the controller 16, which may include a surface heater, is energized at a lower temperature.

A log-periodic aerial array comprises a plurality of loop-type radiating elements, which are disposed in parallel planes and which are fed by a bifilar line (Fig. 1, not shown). Lumped impedance is introduced into at least one of the loops with the object of reducing the loop's mismatching shunting effect at frequencies appreciably lower than its resonant frequency. As described, insulators 25, 26 are inserted in a loop 4 so that they are equally spaced about connection points 21, 22 of a feed line 1, and so that the distance L between them is 0À45 x the perimeter of the loop.

Abstract: 1,253,005. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Feb., 1970 [14 Feb., 1969], No. 6628/70. Heading H4K. In a multistage switching network in which each crosspoint relay on operating closes a selfholding circuit and opens its operating circuit, the latter incorporates a switch which is turnedon by the flow of operating current so as to set a bi-stable whereby the cessation of the operating current if and when the crosspoint operates together with the set state of the bi-stable denotes correct actuation of the crosspoint. If the crosspoint does not operate properly an alarm is actuated a preset time, which allows for contact bounce &c., after setting of the bi-stable. In well known manner a crosspoint such as KP in a matrix CKV1 of a stage KC is energized by selective closure of contacts uk, kh1 and k in the marker St and the matrices respectively. The consequent flow of current through resistor Rmc turns on transistor Tkc and thus sets bistable FFC to the B state. If the crosspoint operates, the reverse bias across diode Dkp due to the closure of the self holding contact kp causes transistors Tc and Tkc to cut-off. Gate Uc is thereby supplied with similar inputs and so opens to mark one input of gate Uz. The results of similar operations in other stages are communicated to Uz so that if the whole of the selected path is completed properly Uz opens to apply a marking to delay circuit TV. The output of the latter, over Sp and R, resets the marker control circuits and the bi-stables. If TV does not produce an output within a given time a fault is signalled over lead FA and a fault diagnosis is effected by examining the gates Uc.

Abstract: 1295116 Vibrators; connecting-rods VIBRATECHNIQUES SA 19 Nov 1970 [21 Nov 1969] 55085/70 Headings F2T and F2X A vibrator comprises a support 12 for a mass, e.g. of concrete, to be vibrated and means for vibrating the support, the latter including a reciprocable connecting-rod 15 having an elastic portion 23 between two rigid portions 21, 22 for increasing the acceleration of the support when it is near its extreme positions of vibration. The elastic portion 23 (Fig. 2) comprises a piston 24 connected to the connecting-rod big end by the rigid portion 22, and adapted to slide in a cylinder 25. This cylinder is closed at both ends by screw stoppers 26a, 26b. The stopper 26a is fixed to the rigid portion 21 and hence the cylinder 25 is connected to the connecting-rod little end. Each of the faces of the piston 24 is provided with a groove 27 receiving the end of a coil spring 28a, 28b bearing respectively against the stoppers 26a, 26b. The springs apply opposite forces to the piston 24 and when the elastic portion 23 is not subjected to any longitudinal stress, these opposite forces tend to hold the piston 24 and cylinder 25 in an intermediate relative position. The big end 16 of the connecting-rod 15 is connected to a pulley 17  driven by a motor 18, and its little end is connected to a piston 14 adapted to reciprocate in a cylinder 13 communicating with a container 1. The container 1 surrounds a coaxial cylinder 3 and the annular chamber resulting is filled with oil and closed at the top by a flexible diaphragm 6. A guide piston 9 fastened at the top to a ring 10 is adapted to slide in the cylinder 3, the ring 10 being integral with a suport table 12. The bottom surface of the ring 10 rests on the diaphragm 6, the vibrations of which are thus transmitted to the table 12. The elastic portion 23 stores energy in the course of its forward and rearward strokes and releases this energy at the ends of the strokes, with the result that for a constant speed of rotation of the pulley 17 the acceleration of the piston 14 is reduced towards the middle of each of its strokes and increased at the end of the stroke, the overall acceleration of the piston 14 (and therefore of the support 12) tending to be practically constant.

In an embodiment, a metal oxide silicon transistor T 3 , connected as a source follower, is interposed between the photo diode D and transistor T 1  of a conventional integrating circuit arrangement (D 1 , T 1 , T 2 ). The gate of transistor T 3  is held at a reference voltage so that the voltage across the photodiode D is maintained constant so that when a pulse is applied to the gate G 1  of transistor T 1 , a capacitance D, which is mainly formed by the drain capacitance of the transistor T 3 , is charged in preference to the self capacitance Cd of the photo-diode D.
