Filed: 1982-09-15
Granted: 1986-09-18
Abstract: Low cyanide nitriding salt baths which are composed of alkali cyanate and alkali carbonate and used for treating components made of steel and iron produce coatings on the surface of the component in some cases and can lead to problems in the use of the components. A satisfactory surface quality can be obtained from nitriding salt baths which additionally contain 0.5 to 100 ppm of selenium.

Title: Automatic setting circuit for adaptive equalisers in PAM TDM systems - has additional periodic signal as frame synch. signal
IPC: H04L25/03
Filed: 1971-07-02
Abstract: The automatic setting circuit which is used for an adaptive equaliser (i.e. a transversal filter equaliser in a TDM system for PAM), has an additional periodic signal transmitted besides the communications signals and acting as the frame or group synchronising signal. At the receiver, samples of this regenerated additional signal amplitude are taken from samples of the amplitudes of all incoming signals and setting criteria for the equaliser are derived from the difference signal and from the regenerated additional signal. This additional signal or synchronising signal alternates in polarity so as to give equal positive and negative amplitudes.

Title: Felt tubular filter for fuel - has longitudinal joint bonded by thermoplastics applied hot then rapidly cooled
IPC: B01D29/00
Filed: 1972-02-09
Abstract: A tubular felt filter is made by bending around a flat blank of the felt sheet into a cylindrical shape and gluing the abutting edges together. Liquid thermoplastics is applied as a thin strip of adhesive from a nozzle along the generator in which the joint of the tube lies thus covering the joint. The nozzle and the tube are moved relative to one another, e.g. the nozzle is stationary and the tube is moved. After the position at which the adhesive thread is applied, it is immediately cooled by cooling roller and pressed onto the felt. Pref., the cooling and pressing take place simultaneously, e.g. the roller is spring-loaded; in addition, further pressing may be applied immediately afterwards, esp. by a spring-loaded block. The adhesive is continuously applied in a simple manner and is immediately rapidly hardened by cooling and pressing on.

Title: Motor vehicle fuel tank - keeps safe volume between fuel level and top, and also has throttled vent pipe
IPC: B60K15/035
Filed: 1972-04-15
Abstract: The vehicle fuel tank which maintains a safety volume between the fuel and the top, also has a ventilation pipe. This pipe is curved in one plane within the safety volume and has two opposite open ends as well as bends. The apices of the bends pointing in opposite directions together with the adjoining open ends in each case are positioned at a distance from the opposite side with a pipe projecting through the wall leading to the central section of the ventilation pipe. The distance of the open ends (8, 9) and of the bends (16, 17) of the ventilation pipe (3) from the corresponding side is smaller than the minimum distance arising after tipping the filled container by 90 degrees between that side and the fuel level (11) as a result of the safety volume. The ventilation pipe contains a throttle at an open end or at the lead in section 15.4.72 as 218299.
Patent DE-2305682-B2 (DE)
IPC: G04C3/06
Filed: 1973-02-06
Abstract: The display system (4) is driven by an electronically controlled drive device (5, 6, 9). The drive device comprises an unbalance system (5) which is controlled by an electronic switching device (9) and, via a gear (6) drives the display system constructed as a pointer mechanism. The unbalance system (5) can oscillate at a first or at a second frequency. Also present are a quartz oscillator (1) and an electric frequency divider (2). The output of the frequency divider is connected to one input of a bistable flip-flop (3). With each zero passage, the unbalance system generates a voltage pulse which is fed via a pulse-shaping stage (5a) to a further frequency divider (8). The output of the further frequency divider is connected to the other input of the bistable flip-flop. The two said frequency dividers are constructed such that the pulse frequency of the pulse trains fed to the two inputs of the bistable flip-flop deviate only slightly from one another. The electronic switching device (9) is controlled by the pulses occurring at the output of the flip-flop, whose width depends on the phase relationship between the said pulse trains, and the unbalance system is influenced to oscillate either at the first or at the second frequency. <IMAGE>

Granted: 1997-11-26
Abstract: For the lateral alignment of a fabric selvedge during sewing with a sewing machine (4, 6), there is a guide device (2) which can be moved perpendicularly relative to the direction of transport of the fabric (S), in order to press the fabric gently against an abutment (16) designed, for example, as a driven running roller and capable of generating a variable counterpressure. The guide device contains a bead chain 18 guided round two chain wheels. The beads are mounted on a plastic cable, so that they can rotate with the transported fabric. Rotation of the chain wheels causes the lower strand of the chain 18 and therefore the fabric S to be shifted laterally, in order to obtain the desired aligning effect.

Abstract: A digital signal processing device is disclosed. At an intermediate time point between respective sample data of a digital signal input is interpolated data expressed by the formula   <IMAGE>   wherein Rl, m and n are positive integers. The digital signal interpolated with this interpolation data d is applied to a digital-to-analog converter where it is converted to an analog signal. This interpolation serves as a low-pass filter for removing unnecessary harmonic components, with the result that a analog filter used in a posterior stage after the digital-to-analog converter requires no steep characteristics and hence can be of a remarkedly simple structure and be manufactured at reduced cost.

Abstract: A hole is drilled in a front (9) of hard material, such as rock, by fragmenting the hard material with impact hammers (13a) along a plurality of spaced-apart paths extending in parallel planes (P1, P2,P3), each of which extends in a plane different from the planes in which the adjacent paths extend. The hammers (13a) are mounted in parallel, spaced-apart relationship on a support (15), each hammer having a head (17) spaced from the support (15) by a different distance from the adjacent hammer heads. The hammers (13a) are driven towards the front (9) by a motorized vehicle (5), and are simultaneously reciprocated in a plane parallel to the front (9) The fragmentation by impact along the paths causes simultaneous fragmentation by shear between the paths.

IPC: G01B11/10
Filed: 1987-03-30
Abstract: A light beam is repeatedly deflected in the longitudinal direction through a holographic element HOE by means of a rotating multi-faceted mirror. This HOE is so formed that the beam entering at different angles leaves the HOE as a telecentric beam. Through a further HOE the telecentric beam is diffracted onto an electro-optic transducer. In the region of the telecentric beam is located an object to be measured, and the time of the interruption of the telecentric beam by means of this object enables the dimension of the latter to be determined. The production of the telecentric beam and the deflection of the latter onto the transducer by means of the HOE allows a simple cost-effect manufacture as well as a simple evalution of the measurements with increased precision. The manufacture of the HOE is likewise simple.
