Title: Improvements relating to automatic rivetting machines
Inventor: CHRISTIE DAVID
IPC: B21J15/32
Filed: 1961-06-09
Abstract: 930,164. Riveting. BAXTERS (BOLTS, SCREWS & RIVETS) Ltd. April 26, 1962 [June 9, 1961], No. 20892/61. Class 83 (4). In an automatic riveting machine in which rivets are automatically fed to a rivet-holder for setting by a reciprocating punch tool cooperating with a stationary anvil, an expansible rivet holder is slidably mounted on the punch tool to which it is resiliently coupled to move between an upper loading position in which the holder projects below the punch tool and a lower ejection position in which it is arrested while the punch tool moves downward to expand the rivet holder and eject and set the rivet. The rivet holder comprises a sleeve 5 divided into two semi-cylindrical parts 6 and held by an integral collar 7 in a head 8, with sufficient clearance to permit limited expansion of the halves. Two spring-loaded shoes 10 press the halves on to the punch tool 1 to ensure that the rivet-holder and tool move together until the rivet holder is positively arrested by an upper stop 18 and a lower stop 17. With the punch in the raised position a rivet 15 from a delivery shoot enters the rivet holder through a T-shaped slot in the side and is supported by its head on a shoulder 14. The punch descends carrying the rivet holder with it until the lower end of the rivet is just supported on a locating pin 4 of an anvil 2. At this point the rivet holder engages the stop 17 and as the punch tool 1 continues its downward movement the halves 6 are opened and the rivet is ejected. In a modification, the rivet holder consists of a resilient sleeve split longitudinally at one side so as to normally grip the tool resiliently, the sleeve carrying a laterally extending arm movable between the stops 17 and 18.

Abstract: 149,217. Huth Ges., Dr. E. F., and Loewe, S. June 11, 1917, [Convention date]. Thermionic relays.-In a thermionic amplifier of the type in which amplified impulses in the anode circuit are led back to the grid circuit to obtain further amplification by retroaction, the anode circuit is coupled to an aperiodic circuit of the receiving system or to an intermediate circuit coupled thereto. The highest possible degree of amplification is stated to be obtained without the valve oscillating. In the arrangement shown, amplified low-frequency pulsations in the anode circuit of the valve 7, are led back to the intermediate circuit 4, 5 coupled to the aperiodic circuit 2 containing the detector 3 and condenser 4, and are thence impressed on the grid circuit by means of the transformer 5. The coupling of the anode circuit and the intermediate circuit may be varied to obtain the best results. The condenser 4 may be omitted, in which case the circuit 2, 3, 5 becomes the aperiodic circuit. The telephone may be connected to the anode circuit, or across the condenser 4, or in place of this condenser if it has been omitted.

[Also in Division H2] A D.C. to D.C. converter comprises (Fig. 4 two transistors tr1, tr4 and two diodes di1, di2, forming a bridge, a D.C. supply being connected to apices A and C, an auto-transformer connecting the apices B, D, and a load re5 being connected between a centre tapping on the autotransformer and the apex C. The transistors are switched alternately so that current (shown as negative current flow) flows in alternate directions in the primary winding en7 + en8 of the auto-transformer, and a voltage of half the value U is developed in the secondary winding of the auto-transformer, i.e. one of the windings en7 or en8. This voltage is developed between the centre tap which - U is always at a potential and the 2 point C which is earthed so that a direct current of twice the primary current i passes through the load at a voltage of U/2. Additional windings on the transformer are provided and included in the emitter base circuits of the transistors to effect switching. To provide an output voltage other than U - additional tappings on the auto-transformer 2 are used. As shown in Fig. 7 with the transistors connected to intermediate tappings primary current flows through a winding 2n + n1 and secondary voltage is developed across n + n1 giving an output voltage greater than U -. In a further embodiment (Fig. 8, not 2 shown) in which the diodes are connected to intermediate tappings on the transformer and the transistors are connected to the ends a U voltage less than -is obtained. 2

Abstract: 975,100. Measuring bridges. WAYNE KERR LABORATCRIES Ltd., and J. MILDWATER. June 4, 1963 [June 6, 1962], No.21901/62. Heading G1U. Apparatus for adjusting the amplitude of an alternating electrical signal to bring a separable component thereof to a predetermined value comprises a potential divider consisting of a fixed and variable impedance; means for applying the electrical signal across the potential divider; a high gain amplifer with means for applying to the amplifier input the difference between the fraction of the voltage developed across a part of the potential divider and a reference voltage of the frequency and in phase with the separable component and of the required magnitude of the component; means for, separating the separable component from the output of the amplifier; and means for applying the separated component as a control voltage to the variable impedance to adjust the impedance so as to bring the net separable component at the amplifier input to zero. A standard impedance 13, Fig. 1, is connected in series in the input of amplifier 12 which includes the unknown impedance 10 in a feedback path. If the impedance 13 is a pure resistance the output voltage E of the amplifier equals (P + jQ)E s , where E s  is the input voltage from transformer 16 and P and Q are the resistive and reactive components of the unknown impedance 10 divided by the magnitude of resistance 13. This voltage is applied to a potential divider comprising resistance 18 and a bi-directional transistor 19, the resistance of which is controlled by the signal applied to its base. A voltage E s  from winding 21 is subtracted from voltage E o  across transistor 19 and fed to amplifier 20, the output of which passes through a phase sensitive detector 22 to the transistor 19. Thus the circuit is automatically balanced so that the in-phase input to amplifier 20 is zero, and the phase quadrature component at the input is shown to be equal to j Q/P E s . This voltage is measured by passing it through 90 degrees phase shifter 25 and phase sensitive detector 26 to meter 27. The meter 27 can be calibrated by supplying a standard voltage to it, and the resistive component of impedance 10 can be measured by supplying voltage E through switch 28 to detector 26 and meter 27; the meter then indicates the value of PE s , and the calibration is the same. If the impedance 10 is mainly reactive, a reactive impedance, e.g. a standard capacitor, may be used for impedance 13. Interchanging impedances 10 and 13 give measurements in terms of admittances instead of impedances. The transistor 19 may be replaced by a thermistor which may be arranged in the feedback path of an amplifier, Fig. 2 (not shown) and may be heated directly or indirectly by the output from detector 22. The potential divider may comprise a fixed reactance in series with a controllable reactance; if a 90 degrees phase shift is required in the divider, one component may be a resistance and the other a reactance.
