Abstract: An electrophotographic method is disclosed for forming an image which comprises a neutral (possibly black) component and at least one colour component and in which there is no contamination of the neutral component by a colour component. An original (1) is used in which the component corresponding to the desired neutral component is prepared from a substance which absorbs light (6) in only a limited region of the spectrum, this region differing from each region of absorption of each other component. This allows each original image componentto be reproduced independently of each other component by exposing a charged photoconductor to the original image using light absorbed solely by the component concerned and developing the resulting charge image with a toner of appropriate spectral absorption. The toner image components thereby obtained can be transferred in register to a single receiver.

Abstract: Described is a method of producing silicone aqueous emulsion compositions which cure at room temperature by the removal of water to form elastomeric coatings or films with superior surface gloss, good adhesion to substrates, and rustproofness. The method prepares an emulsion of polydiorganosiloxane having at least two hydroxyl groups per molecule, colloidal silica or alkali metal silicate, curing catalyst, emulsifier, and water, the emulsion having a pH of from 9 to 12. After ripening for a period of time, so that an elastomeric material will be formed when water is removed at room temperature, an amino-functional silane or its partial hydrolyzate is added to give the emulsion its improved properties.

Abstract: An overvoltage protection device, especially for telephone equipment and the like, comprises two protectors (10, 12) connected directly in parallel. One protector, for example a back-to-back semiconductor diode (14), has a breakdown voltage below which it is a high impedance. Between the breakdown voltage and a failure voltage it has a lower impedance. Above the failure voltage it has negligible impedance. The other protector (10), for example a gas tube, has a range of operating voltages which extends from below the breakdown voltage of the diode, to a voltage between the breakdown voltage and the failure voltage of the diode. In operation the two protectors interact, the diode operating, for example, on faster surges and, in so doing, slowing the surge front so as to increase the likelihood that the gas tube will fire.

Abstract: A coupling device in extension drill equipment for percussive drilling is provided with means (2,3;2,24;2,30) which besides transmitting compressive pulses in the drill string in the direction towards the drill bit by reflection also transforms tensile pulses in the drill string into compressive pulses. Preferably, the joint device includes outer sleeve members (1;21,22;22,27;32,36) axially movable relative each other and provided with cooperating surfaces (2) and an inner rod element (3;24;30) connecting the members. Upon compressive stresses these surfaces (2) abut each other under pressure, while they become separated by tensile pulses. Also preferably, the joint device includes spring means (19) for absorbing torsion pulses in the drill string.

Abstract: To decode a binary signal without regard to the speed at which it is read, each transition in the binary signal is detected, and the time lapse between successive transitions is determined to thereby establish the length of a pulse in the binary signal. The length of one pulse is compared with that of the immediately preceding bit cell to determine whether their lengths are approximately the same or vary by a factor of approximately 2, and any change in the binary state of the signal is determined accordingly. A multiplexing technique is employed to simultaneously decode a number of signals in this manner.

A locking arrangement (16) is so arranged, when in a locked position, as to maintain the connecting components fully connected one to the other and, when in a releasing position, as to permit the coupling components to be separated. The locking arrangement comprising a locking device (17) attached to one of the coupling components (3) and so arranged, when in said locked position, as to be introduced into a recess (24) in the other coupling component. Sealing device (12, 14) are so arranged, when in said locked position, as to provide a seal between the coupling components. The second coupling component (2) exhibits a further recess (25) inside which the locking device is first brought for the purpose of locking the coupling components (2, 3, 4) in an outer locked position as the two coupling components are connected one to the other. In the outer locked position incomplete sealing is pro­vided, in which the two coupling components are locked in such a way that they are prevented from being separa­ted but are allowed to be brought further together into the first-mentioned locked position in order to permit the coupling components to be fully connected one to the other. In the presence of pressurized medium, an indi­cation that the outer locked position has been adopted can in this way be obtained from the leakage of pressu­rized medium.
