Abstract: For the enciphering of data by the use of an IC card (K) equipped with at least one integrated circuit and of a terminal (E) connected to a computing unit (R), there are enciphering devices (V1, V2) provided both in the IC card and in the terminal. Data (OD) output from the terminal are enciphered by the enciphering device (V1) on the IC card by means of a first code (KC) and are transmitted to the terminal. There, they are enciphered by the further enciphering device (V2) by means of a further code (KT) and transmitted to the computing unit. In the computing unit, a deciphering is carried out with both codes, in order to obtain the data of the terminal without enciphering. The data sent to the IC card from the terminal are preferably without enciphering. The enciphered data are transferred from the terminal to the computing unit preferably only after intermediate storage in the terminal and after combination with further data enciphered from further IC cards. <IMAGE>

Abstract: A centrifuge bowl for oscillating bowl type rotors with two grooves in opposite sides of the bowl to receive the rotor-bearing pins, so that each groove has a bottom surface and is bound on the side facing the bowl aperture by a curved surface is provided. This achieves higher load change cycles so that higher fields of gravity are possible without the occurrence of the usual material fatigue in the area of the grooves receiving the bearing-pins, that is, of fissuration, because the bottom surface has a cup-shaped indentation which, in the peak area of the curved surface is located ajacent to the latter, and there is at least one slot opening into the indentation in the peak area of the curved surface.

Abstract: Methods and apparatus for the recording and playback of animation control signals, including voice, are disclosed. In accordance with the method, a dual track cassette recording is made, one track consisting of a voice channel and the other track consisting of a plurality of control signals for the control of animation, and in some instances for control of the speaker or speakers through which the voice channel will be played back, whereby two or more animated characters may appear to speak to each other or speak or sing in unison are disclosed. The control signals are pulse width modulated signals to provide, in general, proportional control signals to provide proportional control, through appropriate servo motors and the like, of the animated elements such as mouth, eyes, etc. of the animated character. The pulse width modulated signals, together with a sync signal, are recorded directly on a cassette tape without modulation on a carrier frequency, despite the varying unsymmetrical wave forms, thereby allowing the compaction of a substantial number of control signals within the frequency band of reasonably priced playback units. The number of animation control channels achievable in a single track is relatively large, allowing the interconnection of one or more additional animated characters and the use of one or more channels to control which character or characters the voice channel is played back through. The system operates on an appropriately recorded standard cassette and playback unit which may be lo- cated in one of the animated characters or otherwise, with the exception that the cassette includes an additional depression or hole which provides clearance for a cooperatively disposed operating element of a switch which, upon depression by the insertion of a standard (nonanimaton) cassette, will redirect the signal from what would have been the animation control system to a summary amplifier to result in the audio channel providing monaural playback of standard stereo cassettes. Various embodiments are disclosed.

Abstract: An electric device with an operation indicating light has a base and a case transversely divisible in a main frame and a case cover. The main frame is fitted to the base at one open end of the frame. A resin material is injected into the space provided by the base and the main frame. The case cover is fitted to the other open end of the main frame so that an operating indicating lamp can be seen through an indicating hole in the case cover. Thus, the device can be easily assembled, and the resin material does not leak from the gap between the operation indicating lamp and the indicating hole. Cracks are prevented from developing in the solder connecting the lamp to the circuit board. In addition, the lamp can be positioned at a high precision because no packing is required to prevent resin leakage.

Abstract: Provided is a rust preventive coating composi­tion comprising, in terms of solids, 100 parts by weight of a vinylidene chloride latex and 0.5 - 50 parts by weight of a tannic substance. The vinylidene chloride latex is obtained by emulsion-polymerizing in the presence of an anionic emulsifier a monomer mixture composed of 20 - 95 wt.% of vinylidene chloride, 5 - 80 wt.% of a monomer copolymerizable with vinylidene chloride and 0.1 - 5 wt.% of an ethylenically-­unsaturated carboxylic acid. The rust preventive coating composition exhibits superb rust preventive effects when applied to iron and iron alloys. Although the vinylidene chloride latex is acidic, it is not coagulated by the addition of the tannic substance so that the tannic substance is contained in a state dispersed stably. Good leveling effects are also obtained owing to the inclusion of the unsaturated carboxylic acid component in the vinylidene chloride latex.

IPC: E21B43/26
Filed: 1987-09-14
Abstract: A process for sequential hydraulic fracturing of a hydrocarbon fluid-bearing formation. A fracture is induced in the formation by hydraulically fracturing via one wellbore. Thereafter, while the formation remains pressurized from the first induced-fracture operation, a second hydraulic fracturing operation is conducted via another wellbore substantially within the pressurized formation area of the first fracturing operation which causes a fracture trajectory to form contrary to the far-field in-situ stresses. This second hydraulic fracture will tend to curve away from the first hydraulic fracture and has the potential of intersecting natural hydrocarbon fluid-bearing fractures in the formation.
