Title: Improvements in or relating to counting apparatus
IPC: H03K21/08
Filed: 1960-12-15
Abstract: 928,797. Counting apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 15, 1960 [Dec. 15, 1959], No. 43183/60. Class 106 (1). Counting apparatus consists of a first counting means, capable of counting, in a positive sense, electrical pulses succeeding one another at a high rate, a second counting means capable of counting in a negative sense at a slower rate, means for supplying transfer pulses to both counting means and gating means for terminating the transfer pulses in response to a predetermined condition of the first counting means. High-speed electronic decade counting stages DEI ... DEIV count electrical pulses from input E when switch C, operating switching stations CI . . . CV, C<SP>1</SP>I ... C<SP>1</SP>V, C<SP>x</SP>, is in position 1, each stage transferring a pulse to the next stage as it passes through its zero position. Shaping circuits TI . . . TIV are associated with each stage of the electronic counter, each of which can operate at a rate of the order of 1 Mc/s. In order to read-out a count the stages are separated from each other by switch C in position 3. Microswitch C<SP>x</SP>, operated by a cam F on the axis of switch C, causes a multivibrator M to apply transfer pulses via gates PI . . . PIV and amplifiers AI . . . AIV to all the electronic counting decades DEI ... DEIV and simultaneously to associated mechanical decades DMI ... DMIV which count from zero in a negative sense. As each stage DE reaches zero the associated gate P cuts off. When all the gates P have cut off the mechanical decades DMI ... DMVI register the count previously held by DEI . . . DEIV, DMV, DMVI. If counting is to be resumed from a previous total, switch C is put in position 2 and the multivibrator M applies transfer pulses to the counting stages until the mechanical decades DMI ... DMIV register zero and the original count is again set up in stages DEI ... DEIV, DMV, DMVI. In order to zeroize the counting means, switch Q, operating switching stations Q<SP>1</SP>, Q<SP>11</SP>, Q<SP>111</SP>, QV, QVI is put to its unstable setting 5. An external circuit (not shown) connected by conductor 6 and switch Q<SP>111</SP> zeroizes the electronic decades. Switch Q<SP>11</SP> sets the multivibrator, Q<SP>1</SP> frees the gates PI ... PIV and transfer pulses from M zeroize the mechanical decades DMI . . . DMIV at which point contacts t 0  close gates P. DMV, DMVI are similarly zeroized by the multivibrator M via switches QV, QVI.

Abstract: 985,674. Converting. ALLMANNA SVENSKA ELECTRISKA A.B. Dec. 4, 1961 [Dec. 6, 1960], No. 43224/61. Heading H2F. A polyphase converter is provided with a normal delay angle control system and additional control means for ensuring suitable commutation margin under maximum inverter operation, these means including means to produce a D.C. magnitude corresponding to load current and means responsive to the commutation voltage (i.e. the difference between the phase voltages undergoing commutation) producing an A.C. magnitude proportional to said commutation voltage and displaced ahead of it by an angle corresponding to the necessary commutation margin at zero load current, and means for comparing the said magnitudes and furnishing a firing pulse when they are equal. As shown grid pulses to a converter element 4 are derived through a transformer 6 and transistor 3 from a transformer 1. A voltage uα 90 degrees displaced from the commutating voltage u k  and a regulating direct voltage e r  provide the normal delay angle control. For the additional control at maximum inverter operation a voltage u v  ahead of u k  by 20 degrees and a voltage u, derived from the load current I through a resistor R, are utilized to operate on the transistor 3 and furnish a firing pulse when they are equal. The resistor R 1  may be linear or non-linear.

Abstract: 1,186,129. Liquid ring pumps. I.C. JENNINGS. Sept. 30, 1968 [March 7, 1968], No.46322/68. Heading F1C. A multi-stage liquid ring vacuum pump comprises a separating member between two successive stages, cold seal liquid being introduced from an entry means to a conduit in the casing and thence into a groove in the separating member adjacent the inner edges of the impellers.
