Title: Peak value detecting circuit
Inventor: AKASHI MITSUHISA
IPC: H04B17/00
Filed: 1995-01-04
Abstract: PURPOSE: To cancel the temperature dependency of an output voltage from the peak value detecting circuit at the time of input signal interruption by always fixing a bias current to a diode for peak value detection corresponding to a temperature change. CONSTITUTION: A resistor R1 for bias current monitor is provided serially to diodes D1 and D2 for peak value detection, and a feedback circuit is constituted to compare a voltage with a reference voltage V2 set to provide a desired bias current and to feed it back. At such a time, a bias current value is set to be a forward voltage VF of the diodes D1 and D2 so that efficiency for the peak value detection of a small amplitude signal can be improved. Further, since the bias current is always fixed corresponding to the temperature change by this feedback circuit, the temperature dependency of the output voltage from the peak value detecting circuit at the time of input signal interruption can be eliminated.

Patent DK-92593-A (DK)
Inventor: JENSEN LAURIDS A
IPC: E04B1/41
Filed: 1993-08-11
Abstract: In a concrete anchor 1 of the type which comprises a stem 2, and anchor plate 3 for embedding in a concrete element (not shown), and a cutting head 4, intended to interact with lifting tackle, likewise not shown, the novelty resides in the fact that the concrete anchor 1 is composed of plastic material with reinforcement 5, the wires or filaments of which, in particular, run right out into the anchor plate 3 and the cutting head 4. The concrete anchor 1 can thereby be manufactured relatively cheaply, and because it cannot rust, both the loss of strength caused by rusting and unsightly rust streaks on the concrete elements are avoided. <IMAGE>

Title: Column shift system for a data processing machine
IPC: G11C11/403
Filed: 1955-01-07
Abstract: 804,172. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 7, 1955 [Jan. 11, 1954], No. 523/55. Class 106 (1). A column shift system for a data processing machine having a storage device comprising a plurality of orders of storage elements, means for connecting the storage elements successively to a source of input data and means for conveying data out of successive ones of said storage elements during successive time intervals, includes means for conveying a first portion of said data into selected ones of said storage elements in a timed sequence delayed by one of said time intervals behind the sequence in which said first portion of data is conveyed out of said storage elements during a first group of said time intervals, means for adding a selected integer to a second portion of said data and means for conveying the sum of said integer and said second portion into said storage elements in a timed sequence delayed by two of said time intervals behind the sequence in which data is conveyed out of said storage elements during a second group of said time intervals. The apparatus described, Fig. 4, comprises the accumulator and adder described in Specification 800,273-the accumulator being shown in Fig. 4 as a storage device 1 and a delay 4-and the operation described is that of " normalising " a floating point decimal number registered in the storage device, that is the numerical portion of the number is shifted to the right in the store until the extreme right-hand digit is not zero and one is added to the exponent, which occupies the first two left-hand positions of the store, for each shift of the numeric portion. When the control unit receives a " normalise " instruction the right-hand end storage position is examined to see whether the digit therein is zero and if it is zero cyclic shift of the contents of the store is commenced via a gate 5 and the adder, the other entry to the adder being zeros. This shift continues until the last two digits (the exponent digits) leave the store 1 which digits by-pass the delay 4 via a gate 3 and have unity added to them before returning to their original position in the store. The net result is that the numerical portion of the floating point number is shifted one place to the right (that is it is divided by 10) and unity is added to the exponent. In Fig. 4 the exit point from the delay 4 corresponds to the " on time " output from the accumulator as described in Specification 800,273 and the exit point from the store 1 corresponds to the " early " output from the accumulator.

Abstract: 365,762. Respiratory apparatus. MUNTWYLER, A., Andermatt, Switzerland. Jan. 7, 1931, No. 583. Convention date, Jan. 20, 1930. [Class 81 (ii).] Apparatus for protection against poisonous and injurious solids, vapours, or gases comprises means for drawing in and filtering air, automatically regulating its pressure and quantity as required, and supplying it to respirators having inhaling and exhaling valves. Air is drawn in through any of pipes 1, 2, 3 by means of a fan 5, blower, or the like, and passes through some or all of the filters 7, 71, 7<11>. Reserve filters 8, 81, 8<11> may be provided. Air taken from tapping points 9, 10 can be analysed in apparatus 11, 12. Purified air passes by a pipe 13, where its temperature and humidity may be adjusted, to a bellows 14 having an air inlet valve 17 actuated by a rod 18 depending from the movable top 16 having a balancing weight 20. The valve casing 17<1> is made of varying cross section. The pressure in the regulator is varied by altering the load on the top 16. If the air supply fails, a valve 23 is opened by a, rod 21 and air enters from a cylinder 26. A check valve 27 prevents return of air to the filters. The consumer wears a respirator connected to tapping points 28 by a hose 31 which may be divided at the coupling 32, which is secured to a body belt. It is therefore possible for an individual wearing an ordinary respirator to connect himself to the installation without removal of the respirator. Instead of the regulator 14, a similar regulator may be inserted between each respirator and a tapping 28 of the supply pipe 13. Pressure gauges 40 may be arranged at desired points. The whole installation or the individual parts may be portable. The air may be enriched with oxygen which may be supplied in variable doses, or adapted to the air consumption by connecting an oxygen container to the pressure regulator provided with an oxygen inlet valve.

Title: Polymer dispersions
IPC: C08L25/06
Filed: 1944-01-12
Abstract: Aqueous polymer dispersions which comprise polyvinyl chloride, from 10 to 100 parts by weight of polystyrene per 100 parts by weight of polyvinyl chloride, and a plasticizer.  Plasticisers specified are di-n-propyl and di-n-butyl phthalates, and tricresyl and triphenyl phosphates.  The dispersions may be made by mixing a dispersion of polyvinyl chloride with a dispersion of polystyrene which separately may be made by known processes.  The plasticiser may be incorporated either with the polyvinyl chloride dispersion or the polystyrene dispersion separately or it may be incorporated with both dispersions separately.  Or it may be incorporated with the combined dispersions after mixing. Thickening agents such as proteins, salts of alginic acid, natural gums and resins, and alkali metal salts of polyacrylic acid, generally in proportions between 0.1 and 5 parts per 100 parts of nonaqueous material in the dispersion, may be added.  The dispersions are especially suitable for the production of hollow-shaped articles by a dipping process.  A former of glass or porcelain is immersed in the dispersion, withdrawn, dried and backed. The coating is then removed from the former.  A series of coats may be applied to the former.  In examples: (1) an aqueous dispersion of polyvinyl chloride and the sodium salt of sulphonated oleic acid is mixed with an aqueous dispersion of polystyrene and the above salt, water added and stirred.  An aqueous paste of the sodium salt of sulphated sperm oil alcohol and dibutyl phthalate is added, stirred, heated and strained. Finally, an aqueous syrup of ammonium polymethacrylate is added. Formers are immersed in this, withdrawn, dried and heated.  This may be repeated several times; (2) an aqueous dispersion of polyvinyl chloride, dibutyl phthalate, the sodium salt of castor oil fatty acids, sodium stearate, and the sodium salt of sulphonated oleic acid are mixed with an aqueous dispersion of polystyrene and the sodium salt of sulphonated oleic acid.  An aqueous syrup of ammonium polymethacrylate is added and the treatment of example (1) applied.  Specifications 410,132, 494,772, 573,366, 575,901 and 577,317 are referred to.

Title: Improvements in resonance spring operating mechanism, more particularly for electric switches, clocks and the like
IPC: H02K7/065
Filed: 1931-01-07
Abstract: 365,764. Electric clocks. LANDIS ET GYR SOC. ANON., 1, Hofstrasse, Zug, Switzerland. Jan. 7, 1931, No. 587. Convention date, Jan. 15, 1930. [Class 139.] In operating mechanism for switches. multipletariff meters or like apparatus of the type in which a step-by-step driving wheel is directly controlled by a resonance spring responsive to a predetermined f r e - quency, a detent system is provided to prevent operation of the driving wheel by incorrect frequencies or by shock. As shown in Figs. 1 and 2, a spring 3, adapted to respond when current of correct frequency is supplied bv the magnet 11, directly operates a wheel 2 through a tongue 4 to effect the desired control. Mounted on the shaft 1 of the wheel 2 is a detent wheel 10 which co-operates with a pin 5 on a pivoted lever 8 to lock the wheel 2 against operation. The lever 8 rests upon a second resonance spring 7. When the operating current is supplied both springs vibrate, the lever 8 being thrown upwardly to release the wheel 2 for operation by the spring 3. The springs may have different natural periods of vibration and operation may be effected by current of an intermediate frequency or by two currents of corresponding frequencies one of which may be the frequency of the mains. The spring 7 may be dispensed with, the lever 8 being adapted for operation bv the spring 3. In the event of false operation of the apparatus by impulses due, say, to excessive voltages on switching in apparatus the wheel 2 is released but is again locked by engagement of the pin 5 with a further notch in the wheel 10, the effect of disturbing impulses being rendered ineffective by providing gearing such that a control operation takes place only after several rotations of the wheel 2.
