Title: Improvements in Automatic Cut-outs for Electric Circuits.
Inventor: JOHANSSON ROBERT
IPC: H01H73/64
Filed: 1916-12-28
Abstract: 108,998. Johansson, R. Dec. 28, 1916. Automatic circuit - breakers. - Comprises a device for use as a substitute for fusible cut-out plugs in house installations, arranged in such a manner that, after operation, the contacts cannot be reclosed without removing the plug from its socket, and that sparking is prevented. T h e plunger e is formed with a wedge end to engage a corresponding recess in the stem of the contact c, and it is held therein against the action of a spring k by a pivoted latch l. The tail of the latch is connected with a link o which extends upwards to engage the armature lever v, r of an electro-magnet s, the winding of which is connected to the metal sleeve b of the plug and, through the latch and plunger, to the contact c. Upon overload, the armature is drawn down and the latch disengaged, whereupon the plunger is shot upward from the contact. A pair of shutters y carried by spring levers 2 is mounted above the contact; upon withdrawal of the plunger, these close together and form a barrier preventing the passage of sparks and the re-insertion of the plunger in the contact; they can be withdrawn only by manipulation of the levers 2, and to effect this the plug must 'be removed from its socket. The wire connecting the sleeve b with the magnet winding may be made to serve as a. fuse, should the mechanical parts of the cut-out fail to act.

Title: Shock spectrum analyzer
Inventor: RATZ ALFRED GEORGE
IPC: G01R23/00
Filed: 1968-04-19
Abstract: 1,220,831. Determining shock spectrum of transient signal. TEXTRON Inc. April 19, 1968 [April 25, 1967], No.18640/68. Heading G1U. The shock spectrum of a transient electrical signal f(t), defined as the plot of the peak response of a single tuned electrical resonant system excited by the transient, over a range of frequencies, is analysed by a system in which the transient under investigation is passed to two multipliers 11, 12 wherein it is multiplied with outputs from variable frequency 13 corresponding to sin wt and cos wt respectively, w corresponding to a particular test frequency at which a point in the shock spectrum is to be established. The outputs from the two multipliers are passed to adjustable low pass RC filters, the time constants of which are related to the Q of the hypothetical resonant system being simulated by the test apparatus. The filter outputs pass to two further multipliers 17, 19, which receive the complementary functions cos wt and sin wt from the oscillator 13. The outputs from these multipliers are subtracted and fed to a peak detector 21. It is shown in the specification that the output from the difference circuit 20 represents the convolution integral of a unit impulse f 1 (t) and the response of the equivalent resonant circuit to the unit impulse i.e. it represents the required test response at a particular frequency. By plotting the peak value of this difference over a range of frequencies, the required shock spectrum is determined. In a more elaborate arrangement Fig. 2 (not shown) the analogue multipliers 11, 12 are replaced by a system wherein the input impulse is modulated on a suppressed carrier wave containing fixed and variable frequency components, and subsequently modulated by the fixed component. The filters 16, 18 remain the same, while the multipliers 17, 19 and difference circuit 20 are replaced by a system in which the outputs from the filters are modulated by the same fixed frequency, 90 degree phase shifted, and then differenced, the differencing stage being followed by a demodulator whose output passes to the peak detector. Filters are included in the system to eliminate harmonics.

Title: Receiver apparatus for multichannel radiocommunication systems
IPC: H04W88/02
Filed: 1971-06-03
Abstract: 1306624 Radio signalling; radio-frequency exchange systems AGA AB 3 June 1971 [12 June 1970] 18747/71 Headings H4K and H4L A radio receiver for a multi-channel communication system in which the channels are used both for calls and traffic, monitors the channels in succession and in response to its predetermined calling code on one of the channels locks the monitoring to that channel. As described Fig. 1, the call signal which consists of three consecutive signals of predetermined frequencies and durations, is supplied via a bandpass filter F, which is switched in steps to the frequencies of the call signals, and a detector D to an integrator Ik. When the output voltage of integrator Ik reaches a predetermined level a trigger T k  is operated and advances a counter R to switch the filter F to its next step and a timer K is triggered to feed a signal via an OR gate G during a time t to stop the channel monitoring unit P. The timer K also supplies a signal to zero the counter R if it has not received a new signal from trigger Tk before the time t has elapsed. When the counter R has advanced a number of steps equal to the number of characters of the calling code it sets a bi-stable B to feed a signal via OR gate G to hold the unit P in its stopped position until the bi-stable is reset by a signal to restart the monitoring. This known arrangement is modified by the addition of an integrator I p , having a time constant substantially shorter than that of integrator I k , which receives the output of detector D and operates a trigger T p . The output of trigger T p  is supplied via OR gate G as a preliminary signal to stop the monitor unit P of trigger T k  and is followed by the output of trigger T k  and this enables a reduction in the time required to recognize a calling signal. If the trigger T p  is operated by a signal of less than the required duration the monitoring is automatically restarted as soon as this signal has terminated.

Title: Improvements in and relating to automatic record-changing talking machines
IPC: G11B17/16
Filed: 1935-07-02
Abstract: 459,155. Gramophones. OFFEN, F. J., and GARRARD ENGINEERING & MANUFACTURING CO., Ltd., Newcastle Street, Swindon. July 2, 1935, No. 18862. [Class 40 (ii)] A record-changing mechanism for gramophones &c. is adjustable to deal with records of different sizes by a control which determines which one of a number of tracks or grooves on a cam is followed by a guide connected with the pick-up or tone arm. A pick-up arm 1 may be coupled by a member 3 and pin-andslot connection to one arm of a lever 4, the other arm of which carries a guide stud 5 engaging in tracks on a cam 6 governing the swinging movement of the pick-up arm during record-changing. The cam 6 has a number of tracks such as 10, 11, Fig. 3, corresponding to the various sizes of records, the guide stud 5 being guided into the appropriate cam groove. The stud may normally follow a given track 10 unless diverted into a track 11, which may be effected by a control knob 14 swinging an arm 17 about a fixed pivot 18, the arm 17 being linked at 19 to a bell-crank, of which one arm 21 is coupled by a spring to the link 19, and the other arm 23 has a pin 24 adapted to press against the lever 4. The lever 17 is held in its extreme positions by a spring 16 and in one extreme position causes a stop 20 on the link 19 to engage the bell-crank and thus withdraw the pin 24 from contact with the lever 4, thereby allowing the stud 5 to follow the track 10. In the other extreme position of the lever 17, the pin 24 is urged by the spring 22 against the lever 4 to guide the stud 5 into the track 11. A lever 25 pivoted on the lever 4, and also coupled thereto by a spring 26, engages the pin 24 so as to constrain the guide stud 5 to follow the track determined by the setting of the control knob 14. The records may be stacked on an offset portion of a fixed spindle 27, Fig. 4, and supported by a member 29 pivoted at 32 on a slide 36 which is adjusted simultaneously with the setting of the knob 14, by a link 37, Fig. 1, to position the support 29 at a radial distance corresponding to the selected size of record, the support 29 being reciprocated by a cam gear 34 after a record has been played, so that a stop 30 may release the lowermost record in the stack and allow it to descend on to the turntable 28. The vertical movements of the pick-up arm 1 which are necessary during record-changing, are effected by a separate cam 12 on the cam drum through linkage not shown. Specifications 399,172 and 399,184 are referred to.
