Title: Improvements in automatic telephone switching systems
IPC: H04Q3/00
Filed: 1923-06-11
Abstract: 221,289. Baron, H., (Aldendorff, F.). June 11, 1923. Automatic exchange systems.-A calling line is connected by its line relay to a pre-selected selector over a common dialling trunk, and a callfinder associated with the selector is started. As soon as the line is found the dialling trunk is released, the remaining impulses going over the callfinder wipers. The line relay may have a light armature operated by the line current and controlling contacts which cause a local circuit to be completed for operating a heavy armature. The line relay 4, Fig. 1, connects the cut-off relay 5 to the call-finder terminals, energizes the group relay 6, and connects the line over the common dialling trunk 7 and the wipers of an allotting switch TF to the impulse relay 19 of an idle connector NS. Relay 6 disconnects battery from all the lines of the group, but relay 4 remains energized over its own contact 32 in series with the left-hand winding of relay 19. Relay 19 energizes the release relay 38 and then controls the stepping magnets 22, 23. Relay 38 energizes the stepping magnet 17 of the call-finder LF over interrupter IP. The latter is of high resistance and allows magnet 17 to operate only when it shortcircuits itself. When the calling line is found, the switching relay 47 energizes relay 12 of the allotting switch TF and cut-off relay 5 releases relay 4 which releases group relay 6. Relay 12 locks up over its right-hand winding and connects interrupter currents from T<1> to the stepping magnet 11. The wipers 8 - - 10 are thus stepped on until wiper 10 finds the dead terminal of an idle link, whereupon relay 12 relapses and switches the trunk 7 through. In a modification the line relay 104, Fig. 2, operates in two steps and the group relay is made slow to release. The first step operates the dotted contacts and energizes group relay 106. Relay 106 energizes an extra winding 104, whereupon the line relay operates fully and connects the line to the dialling trunk 7. The switches LF, TF operates as in the system shown in Fig. 1. Tone signals. In the arrangement shown in Fig. 1, a subscriber gets a tone signal from the winding 200 if when he makes a call his line relay is unable to operate. In the arrangement shown in Fig. 2, the winding 200<1> gives the tone signal only if the line relay can operate. Specification 196,990 is referred to.

Title: Improvements in or relating to linearly extending actuators
IPC: F16H25/20
Filed: 1947-06-10
Abstract: 643,863. Screw-and-nut actuators. BENDIX AVIATION CORPORATION. June 10, 1947, No. 15300. Convention date, July 1, 1946. [Class 78 (iii)] [Also in Group XXXVII] The reciprocatable member 24 in a screw-and-nut actuator carries a pair of abutment members 140, 142 which operate limit switches 20, 22, each member comprising a collar eccentrically encircling said reciprocatable member and movable thereon. The members 140, 142 are rotatably mounted on sleeves 130 and held thereon by fixed shoulders 134 and removable locking rings 136, spring-washers 148 serving to frictionally hold said abutment members from rotation. Adjustment of the amount of movement member 24 can make before switches 20 or 22 are actuated to de-energize motor 44, is effected by first moving the sleeves and abutment members axially along member 24 to give a rough adjustment, and then rotating the abutment members to adjust the height of their switch-engaging portions. Belleville springs 152 located in cups 150 serve to cushion the impact between the sleeves 130 and the casing should the actuator over-run. In a modification, Fig. 3 (not shown), Belleville springs are secured to the sleeves 130 and contact the external faces of abutment cups on over-run. The screw 62 is driven by a reduction gear train 16 through a pinion 66 on a shaft 68 to which shaft is splined a clutch disc 30 which, when the motor and solenoid 94 are de-energized, abuts against a non-rotatable brake ring 75. This ring locks the mechanism by being forced into engagement with the clutch-plate 30 by springs 76 which over-power a spring 74 tending to engage the clutch-plate with a driven plate 28. Upon simultaneous energization of the motor and solenoid the armature 96, together with the brake ring 75, is withdrawn to the right and the spring 74 urges the plates 28, 30 into contact so effecting the transmission of the motor drive to the screw 62.

Title: Electrocardiometer
IPC: A61B5/366
Filed: 1970-04-01
Abstract: 1,260,814. Electro-medical apparatus. FRIGITRONICS Inc. April 1, 1970 [April 1, 1969], No. 15461/70. Heading G1N. In an electro-cardiometer, the ratio of the peak amplitude of theQRS wave to the peak amplitude of the T wave in each cycle is determined to provide an indication of whether the T wave amplitude is above or below a predetermined percentage of the QRS wave amplitude. As shown, electrodes 27, 28 are attached to the left and right arms of a patient and the ECG voltage signal is passed via an amplifier 12 to a trigger circuit which provides an output to trigger a cascade series of monostable multi-vibrators 35-38 upon occurrence of a QRS wave. The multi-vibrators provide outputs B, C, D and E, Fig.4, B having a duration which includes the peak of the QRS wave and C having a duration which includes the T wave. Output B closes an F.E.T. 42 which then allows the ECE signal at terminal A to charge a capacitor 46 up to the peak amplitude of the ECG signal occurring during the signal B, i. e. that of the QRS wave. Similarly, output C and D allow corresponding capacitors to charge to the peak value of the T wave occurring during C and the voltage value occurring after the T wave. The output E then discharges all capacitors in readiness for the next heart beat. The charge on each of the capacitors 46 appears on the source/drain electrode of voltage follower F.E.T.'s 44, (signals F, G and H in Fig. 4) and these signals charge respective capacitors 50 upon the occurrence of the D output. The source/ drain electrode of voltage follower F.E.T.'s 51 then provide voltage signals J, K and L, Fig. 4, 4, representing respectively the peak amplitude of the QRS wave in the previous cycle, the peak amplitude of the T wave in the previous cycle, and the amplitude of the post- T wave signal which acts as a reference level. The outputs J, K, L are connected to a centre-zero galvanometer M as shown, the potentiometer 54 providing the predetermined value. Alternatively, flashing lamps may provide the indication, Fig. 5 (not shown). (For Figures see next page)

Title: Improvements in liquid level indicators
IPC: G01F23/34
Filed: 1924-08-06
Abstract: 242,556. Carpmael, W., (Liquidometer Co., Inc.). Aug. 6, 1924. Indicators actuated by floats. - A liquid level indicator for use with liquids under high pressure, or with one liquid floating on another, comprises a float, transmitting mechanism protected from the liquid, acting on compressible chambers the movements of which are transmitted through pipes to an indicator. The float comprises two cylindrical members such as 133 pivoted on a rod 135 secured to a float arm 139. A sliding weight 140 adjusts the floats to the required position. The float arm carries a yoke 141 with split ends 144, 145 which clamp projections 146, 147 from a cup 142 so as to allow a rocking movement. A shaft 151 is journaled in the cup 142 and carries an arm 156 connected to an actuating rod 158, which, together with the connecting mechanism is protected from the liquid by a casing 132. The shaft 151 carries a grooved member 159 to which a rod 164 is pivoted at 163. A slot 165 in the rod engages a pin 166 projecting from the yoke 141, so that movements of the float arm 139 are transmitted to the rod 158. The compressible chambers 3, 4, Fig. 7, are mounted on supports 178 and are filled with liquid which transmits movements through pipes 6, 7 to the indicator. Brackets 185, 186, Figs. 7 and 8, support a pair of U-shaped supports 189, 190 mounted on trunnions 187, 188 and carried by a yoke frame 191 at the upper end of the rod 158. The members 189, 190 carry adjusting screws 192, 193 on which, are threaded blocks 194, 195 connected by a rod 196, so that the latter can be given any desired eccentricity relatively to the trunnions 187, 188. The rod 196 turns freely in a link 198 mounted to have a rocking movement on pins 199, 200 carried by the ends of the chambers 3, 4. The rod 158 thus transmits to the chambers 3, 4, a movement the amount of which is determined by the eccentricity of the rod 196. Any expanding and contracting movement of the chambers 3, 4 due to temperature changes may thus take place without affecting the movements due to the action of the float. Specification 242,349 is referred to.
