Title: Apparatus for filling and sealing the cartridges of two-piece capsules and the like
IPC: A61J3/07
Filed: 1959-10-29
Abstract: 883,467. Packaging. HOFLIGER, O., and KARG, R., [trading as HOFLIGER & KARG]. Oct. 29, 1959, No. 36755/59. Class 94(1). A machine for filling and closing two-part capsules comprises two rotating adjacent discs 1, 2 with recesses 12, 15 for the upper and lower parts of the capsules respectively, and in which empty closed capsules 5 are fed from a sorting device 6 to the recesses of one disc 1. One part 13 of each capsule is separated from the other part, for the filling operation, by a suction device which sucks it into the empty recess 15 in the other disc as soon as the recesses in the two discs overlap. Each recess 12 has a lower portion of smaller diameter to arrest the capsule cap 14. The discs only partially overlap and rotate stepby-step, through the angles A, B respectively, the recesses of the disc receiving the lower part of the capsule overlapping, in a stationary position, the recesses of the other disc twice, at 16, 17, during one revolution. The filling of the recesses 15 causes a vacuum to be generated in pipes 19 which closes an electric switch and thereby causes the shaft 22, Fig. 6, to be rotated and intermittently advance the discs 1, 2 on shafts 3, 4 respectively, by a revolving arm 29 which moves a roller 31 stepwise around circumferential slots 32 in a wheel 33 on the shaft 4, which shaft also rotates the disc 2 through idler gearing 36, 37. After filling the lower parts of the capsules with e.g. medical powder, by a paddle wheel from a container 7, and compressing the filling by three sprung rams on a vertically reciprocable arm 8, the process is repeated at three containers 7a-7c and two rams 8a, 8b and the parts 13 are then returned by rams (not shown) to the caps 14 in the upper grooves, and the capsules ejected in to a shoot 77.

Title: Apparatus for monitoring the electrical energy delivered by an energy source
IPC: G01R21/00
Filed: 1972-08-09
Abstract: 1397594 Monitoring power supplied to loads SOC DE TRAVAUX D'ELECTRICITE ET D'ELECTRONIQUE DU LANGUEDOC 9 Aug 1972 [9 Aug 1971] 37083/72 Heading H2H A circuit for monitoring the power delivered by a supply 1 comprises a circuit 4 for producing a power signal, a circuit 13 for producing a reference signal corresponding to a nominal power, an adder 11 for producing a signal proportional to the difference between the instantaneous power delivered by the source and the nominal power, a circuit 23 for integrating the difference signal during integration intervals and an adder 30 responsive to the value of the integrator output signal relative to a threshold signal from a source 32. The circuit 4 includes a current transformer 8, a voltage transformer 6, a multiplier 7 and a summing amplifier 10 which sums the power signals for the individual phases if the supply is three phase. The voltage supplied by the reference circuit 13 is set by a consumer, whose supply is paid on a maximum demand tariff, to represent the power consumption per unit time which must not be exceeded. The integrator 23, which may be reset by a switch 28, provides at an output 27 a signal equal to the integral of the difference signal supplied by the adder 11. The adder 30, which effects a subtraction between the integrator output and the threshold signal from the source 32, operates a switch 40 and a relay 38, depending on whether the integrator output is greater or less than the threshold signal, to actuate an alarm and/or interrupt the supply of power to certain installations. A delay switch 39 disconnects the output of the adder 30 from the relay 38 to prevent undesired operation of the alarm at the start of each integration interval.

Title: Waveform synthesis using switching circuits
IPC: H03K5/01
Filed: 1974-08-23
Abstract: 1486811 Inverting NEW ZEALAND INVENTIONS DEVELOPMENT AUTHORITY 23 Aug 1974 [3 Sept 1973 10 July 1974] 37178/74 Heading H2F A method of synthesizing a pulse width modulated waveform comprises generating a first square wave, chopping said square wave at least once each half-cycle with a chopping pulse controlled to have a width inversely proportional to a desired mean value of the output waveform, generating a second square wave of variable frequency and multiplying said second square wave with the chopped first square wave to produce the required pulse width modulated wave, the fundamental frequency of which being equal to the frequency difference between the first and second square waves. As shown in Fig. 3, a clock pulse 6f1 is converted into three-phase square waves by means of a twisted ring counter 12, outputs from which are fed to exclusive OR or equivalent gates 18a ... 18c the three-phase outputs of which are chopped with a pulse y in AND gates 16a ... 16c, the chopping pulse y having a width variable from 0 up to 1/6f1. After further gating at 20a ... 20c, the chopped waveforms are multiplied in exclusive OR or equivalence gate 15a ... 15c by a second variable frequency square wave derived from a ring counter 13. The multiplication is described with reference to the product of two Walsh functions. The three-phase outputs Vml ... Vm3 are used to control conduction of six switching devices in an inverter 19, each switching device being bridged by an inverse diode which is conductive when none of the switching devices are conductive. The output of the inverter 19 may drive a motor, the speed of which is dependent on the frequency difference f1-f2 and the direction of rotation depending on whether f2 is greater or less than f1. The voltage applied to the motor is a function of the duration of the chop pulse y. In Fig. 9 (not shown) f2 is derived from a frequency divider fed from a variable clock pulse generator 10. By varying the division ratio, the voltage/frequency ratio applied to the motor may be changed. Fig. 8 (not shown) depicts a block diagram of a digital system for obtaining the chopping pulse y and determining the frequency of operation.

Title: Isolation of tetraalkyltin
IPC: C07F7/22
Filed: 1956-12-06
Abstract: Tetraalkyltin is separated from impure mixtures of tetraalkyltin and trialkyl tin chloride by reacting the mixture with an aqueous solution of an alkali metal hydroxide to convert the trialkyltin chloride into trialkyltin oxide and separating the tetraalkyl tin, preferably by distillation.  The trialkyltin oxide remaining as still bottoms may be re-converted by addition of hydrochloric acid to the chloride.  Reaction may take place at a temperature of between 75-85 DEG  C.  A trace of a wetting agent, e.g. decylbenzene sulphonate, may be added to the alkali metal hydroxide.  In an example an aqueous solution of sodium hydroxide containing a wetting agent is added to a mixture of tributyltin chloride, tetrabutyltin, dibutyltin dichloride and other impurities at 75-85 DEG  C.  The organic phase is separated and the tetrabutyltin distilled.  Tributyltin oxide remaining is reacted with hydrochloric acid and the tributyltin chloride distilled from the organic phase.  Specifications 695,610, 701,714 and 740,274 are referred to.

Lead organo acid salts specified include lead alkanoates having 1 to 21 carbon atoms in the acid radical such as lead acetate, tetra-acetate, butyrate, formate, oxalate, stearate, palmitate and propionate; their sulphur analogues such as lead thioacetate and thioformate; aromatic compounds such as lead phenate, thiophenate, phenolsulphonate and salicylate; and lead naphthenates and resinates.  The metal alkyl reagents includes those of aluminium, zinc, sodium, potassium and lithium; the alkyl group has preferably 1 to 8 carbon atoms.  Many examples are specified.  Solvents such as benzene, toluene, xylene, hexanes and kerosene.  If desired, the alkyl-lead compound itself may be used as the solvent.  A modification of the process is described in which the organo lead salt is used sequentially with a lead oxide or sulphide which latter is used in such proportions that some but not all the alkyl groups in the compound RaMXb are reacted.  A double salt of the lead organo-acid salt and the lead chalkogen may also be used.  In an example pulverized dry lead acetate in toluene is reacted with triethyl aluminium under a nitrogen atmosphere.  Specification 824,848 is referred to.
