Abstract: ABSTRACT           An electronic taximeter having a microcomputer is adapted to store the current calibration  factor of the meter and cause, upon initiation, display thereof on an electronic display.  An electronic revolution counter is adapted to progressively count and display the revolutions of a speedometer cable input to said meter such that calibration may be checked by driving the vehicle over a measured distance.  Calibration may be readily altered merely by selecting different combinations of an 8-switch dual-in-line package.  Other features include a real time digital clock whereby total engaged time of the taxi during any particular period and the time of commencement and conclusion of a particular fare maybe computed. Tariff rates may be altered by replacement of a single re-programmable and hence re-usable memory chip and a miniature rechargeable battery continuously trickle-charged by the vehicle electrical supply ensures retention of all data including current operation mode data for up to about six months in the event of loss or failure of said supply.  This latter feature is made possible by cyclically dumping, about every millisecond, current operation mode data into low power read/write memory circuits, wherein all other data is also stored, and powering said memory circuit by said battery in the event of said loss or failure.

Abstract: PULP-INSULATED CONDUCTOR CABLE      Abstract of the Disclosure A cable of this invention substantially increases the number of pulp-insulated conductor pairs per unit of cable cross-sectional area.  This permits a reduction in the outside diameter of a cable without reducing the number of conductor pairs or an increase in the number of pairs in a given area such as in an existing underground duct by utilizing substantially more of the cross-sectional area of the duct than had been used in the past.  Each pulp-insulated conductor includes a metallic conductor enclosed in a composite insulative cover which has a controlled dielectric constant and which comprises a pulpous material and a coated layer of adhesive material interposed between the conductor and the pulpous material. The coated layer causes the pulpous material to adhere to the conductor with substantial integrity so that the moisture content of the pulpous material can be reduced over that achieved in prior art processes.  This results in a smaller cross-section of each pulp-insulated conductor which allows the use of an increased number of conductive pairs in a given cable cross-section and without any significant increase in mutual capacitance characteristics of the insulated conductor pairs.  A cable system for providing an increased number of conductor pairs in an existing duct includes a cable of this invention and a pulling eye attached to an end portion of the cable with the diameter of the cable and of the pulling eye being substantially equal.

Abstract: Abstract of the Disclosure Disclosed are contact adhesives, containing aqueous polymeric latexes, particularly acrylic latexes. Contact adhesives are adhesives which dry to a non-tacky state but which will adhere to another surface of the same dried adhesive.  A unique feature of the adhesives is that the polymer used therein has an extremely wide range of molecular weights with substantial proportions of the product having a low molecular weight and substantial portions having a very high molecular weight, preferably with fairly uniform progression from low molecular weight to high molecular weight.  However, blends of a low molecular weight fraction and a high molecular weight polymer may also be used.  The preferred procedure is to prepare an emulsion polymer by reacting part of the material in the reactor in such a way as to obtain a high molecular weight product and to react at least one other portion of the monomer in the same reactor in such a way as to obtain at least one low molecular weight fraction.  The adhesives preferably contain an aminoplast or a phenoplast as a tackifier and crosslinker and may contain a thickening agent such as polyvinyl alcohol.  Also disclosed are articles of manufacture laminated by means of the adhesives and methods of preparing the same.

Abstract: TRANSMISSION SHIFT CONTROL GUIDE AND DETENT  APPARATUS            Abstract:        Transmission shift control guide and detent apparatus includes a mechanism for defining the shift path for any given gear change, and for pro-viding detenting both for ratio selection and for engagement of the selected gear set.  A guide plate defines a predetermined track (40).  A pin (22) associated with the transmission shift lever is movable along this track to establish a precise definition of the path for each selecting and engaging movement. The plate also defines a plurality of depressions (42-58) which form a detent map.  A spring-loaded ball (28) is moved over this map by the action of the transmission shift lever.  This develops pre-determined resistive forces against which the shift lever must be moved during the selecting and engaging movements.  Stresses are absorbed in the guide plate rather than in the shift rail.

Abstract: ABSTRACT: Semiconductor devices and their manufacture.     A semiconductor device for example a p-i-n diode comprises a corrugated semiconductor body (1) having a plurality of complementary grooves (2a, 2b) and ridges (3a, 3b) on opposite sides of the body. The junction (13) between the p-type region (6) and the n-type intrinsic region (10) has substantially the same configuration as and extends substantially parallel to the surface (7), while the junction (14) between the n-type region (8) and the intrinsic region similarly extends substantially paral-lel to the surface (9). Devices with narrow instrinsic regions can be made accurately by diffusion of the p-type region (6) and the n-type region (8) because the whole of the diode can be made relatively thin, for example, 90 micrometres, without sacrificing strength and rigidity. As compared with an equivalent plane device, the active area, and so the current handling capability, is increased. To avoid premature breakdown the diode may be surrounded by a thicker peripheral portion (5). (Figure 1).

Abstract: ABSTRACT OF THE DISCLOSURE      A process and a device for regulating the stimula-tion frequency of heart pacemakers are disclosed. The process comprises generating with the aid of light emitted by a light-emitting element, reflected by the blood of a patient, and received by a light-receiving element, a current flow which causes, in a measuring probe, an increasing of the current flow at a constant probe voltage or a damping of the probe voltage at constant current flow. Thereafter, one of the possible changing values is measured and the change, with time, is evaluated as a measured quantity proportional to the charge, with time, of the blood oxygen saturation, and, as a function of the measured quantity, the stimu-lation frequency of the heart pacemaker is regulated in such a manner that the greatest possible blood oxygen saturation is always achieved with the lowest stimulation frequency. The device for practicing the invention comprises a measuring probe containing at least one combination of only two active optoelectronic elements, one light-emitting element and one light-receiving element; a control circuit electrically con-nected to the measuring probe; a stimulation catheter in which the measuring probe is incorporated, and at least two electric lines leading through the stimulation catheter and electrically connecting the measuring probe to the control circuit of the measuring probe.
