Title: Improvements in or relating to alarm clocks
Inventor: D ANGELY JEAN
IPC: G04B23/04
Filed: 1950-07-24
Abstract: 691,199. Clocks. ETABLISSEMENTS JAPY FRERES. July 24, 1950 [Oct. 13, 1949]. No. 18454/50. Class 139. An alarm clock having a clockwork mechanism associated with an alarm movement in which the dial indicators, the clockwork mechanism and the alarm movement are controllable by means accessible from the outside, is characterized in that an additional alarm control device which is provided with an indicator and which controls the alarm hammer and releases it to sound the alarm at the end of an indicated pre-set. time period is adapted to be coupled with said clockwork mechanism by means of a control member accessible from the outside, said additional alarm control device cooperating with a rocking member provided with two arms one or other of which locks and duly releases the anchor of the alarm movement, according as the additional alarm device is coupled with or uncoupled from said clockwork mechanism. In a first embodiment, Fig. 1, the minute wheel pinion 4 drives a wheel 8 carrying the usual alarm cam 9 which co-operates with a pin 12 on the spindle 10 settable by a knob 11. The cam 9 is pressed against the pin 12 by the resilient arm 38c of a three armed lever 38 pivoted at 38a. The arm 38c normally engages the end 19a of a lever 19 on the spindle 15 of the alarm anchor 16 to prevent oscillation of the hammer 17, 18. 'The arm 38 of the lever 38, 38b, 38c co-operates with three pins 37 on a mutilated gear wheel 22 mounted on a shaft 23 also carrying a mutilated gear 24. The gear wheel 22 meshes with a pinion 26 on a shaft 27 rotatable against a spring 30 by a knob 28. The arrangement is such that rotation of the knob 28 in the direction of the arrow 43 is transmitted via the mutilated gear 24 to a pinion 33 which is carried by a sleeve 34 on which a pointer 35 is mounted. The pointer 35 may be set to a desired time interval on an associated scale. During the setting movement of the knob 28 the mutilated gear 22 has been moved so that the pins 37 rock the three armed lever 38, 38b, 38c against the pressure of a spring 41, the lever arm 38c leaves the extension 19a of the lever 19 but this lever is immediately locked by the arm 38b. A gear 20 frictionally mounted on the minute spindle 1 then drives the pointer 35 back to zero through the gears 22, 24 and 33, the main spring being assisted by the spring 30 during this movement. The lever 38, 38a, 38b is moved slowly in the direction of the arrow 42. When the pointer 35 reaches zero the lever 19 is freed from the lever arm 38b and the hammer 17, 18 is oscillated to sound the alarm until the lever 19 is arrested by the lever arm 38c. In another embodiment, Fig. 2 (not shown), the mutilated gear 22 is replaced by a gear freely rotatable on a shaft for setting purposes but frictionally clutched thereto when rotated by the cannon pinion. The pins 37 are replaced by a cam. In a modification of the first embodiment, Fig. 3 (not shown), the three armed lever does not act directly on the alarm cam 9 but through the intermediary of a resilient lever.

Abstract: 1,021,338. Friction gearing. SIEMENS & HALSKE A.G. May 5, 1964 [May 7, 1963], No. 18534/64. Heading F2Q. A teleprinter cam 3 is frictionally driven from a continuously rotating roller 1 and may be arrested by the engagement of a pin 11 with an electromagnetically operated control arm 7, a freely rotatable roller 6 in the cam periphery then engaging roller 1. The cam 3 is journalled on a spring and pivoted arm 2 and carries the stop pin 11 which is adapted to be arrested by one or other arms 8, 9 of the pivoted electromagnetic control arm 7. When the pin 11 is arrested by arm 9 the roller 6 is freely rotated by roller 1 and its centre lies, for ease of restarting, to the right of a line joining the axes of roller 1 and cam 3. On release from arm 9 pin 11 moves along an arm of a sprung lever 15 until it reaches the end thereof where it may be arrested by arm 8, with a recess in the cam periphery adjacent roller 1. On release of pin 11 from arm 8 the lever 15 urges the pin anticlockwise to bring the cam periphery into engagement with roller 1. Damping levers 12, 13 prevent bounce of cam 3 when arrrested. Lever 2 has an adjustable stop 5 and several freely rotatable rollers may be provided in the cam periphery.

Title: Improvements in and relating to apparatus for measuring the thickness of electrically
Inventor: WATKISS JOHN EDWIN ROBERT
IPC: G01B7/06
Filed: 1958-06-11
Abstract: 860,399. Determining physical dimensions. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 9,1959 [June 11, 1958], No. 18683/58. Class 37. Apparatus for measuring the thickness of an electrically conducting film adhering to an insulating body comprises a resonant circuit having a coil arranged for magnetic coupling to the film, the circuit being fed from a constant amplitude radio frequency source, the frequency being swept through the resonant frequency of the circuit and means for measuring the film thickness as a function of the reactance/ resistance ratio reflected from the film. The Specification describes the measurement of the thickness of an aluminium film AF on a cathoderay tube TE. The resonant circuit is fed from an oscillator FMO in which the frequency is swept at 100 c/s. over a band extending 250 kc/s. on either side of the centre frequency 5 Mc/s. The voltage across the capacitor is fed to an amplifier AD followed by a Foster-Seeley discriminator, the output of which is indicated on a valve voltmeter VV calibrated in terms of film thickness. A Faraday shield FS is provided.. It is shown that the ratio of the reflected reactance and resistance of the film is independent of the mutual inductance between the coil and the film. As film reactance is not a function of thickness and the film resistance is inversely proportional to thickness, the reactance/resistance ratio is proportional to thickness. The output of the amplifier discriminator AD is proportional to frequency deviation and hence charge in reactance and proportional to the Q factor of the resonant circuit and hence inversely proportional to the film resistance. The apparatus is stated to be suitable for measurement of film thicknesses up to 6,000 Angstrom units.

Filed: 1973-04-18
Abstract: 1363060 PAL switching circuit ROBERT BOSCH FERNSEHANLAGEN GmbH 18 April 1973 [20 April 1972] 18715/73 Heading H4F To produce a local sub-carrier signal reversing in phase at line frequency-i.e. 45, 225, 45, 225. degrees-the sub-carrier with a phase of 45 degrees is fed to the collectors of transistors 19, 20, forming part of a bi-stable multivibrator, the emitters being coupled by a centre, earth tapped transformer/inductor 30 and the multivibrator being switched by line frequency pulses at terminal 11. The switching of the multivibrator feeds the sub-carrier alternately to the emitter outputs of the transistors and the transformer 30 causes the required phase reversing line rate output to appear at 32 and 29. The initial 45 degrees phase shift is caused by differentiating circuit 14, 15. Transformer is best resonant at the carrier frequency. A PAL recognition circuit-shown in dotted linesmay be added to achieve the correct phase in the switching.

Abstract: 1,222,108. Photo-electric edge followers. MESSER GRIESHEIM G.m.b.H. April 22, 1968 [April 22, 1967], No. 18930/68. Heading G1A. In an edge follower for controlling a flame torch cutting machine, an auxiliary photo-detector 3 is used to sense the general brightness of the pattern-carrying surface or template, and to adjust an element in the optical system of the apparatus so as to maintain the intensity on the main detector 4 constant and so prevent the follower apparatus being guided away from the edge by the effect of changes in extraneous background illumination e.g. sunlight. The follower system is of the type in which the resistance of a photo-resistor 4, on to which is focused an image of the edge of a line or template, is compared with that of a fixed resistor in a bridge, and unbalance is used to generate control signals for the follow-up motor of the machine. The auxiliary cell 3 may be a photo-voltaic device, photo-diode or photo-transistor and its output is fed after comparison with a fixed level U to amplifiers 1 or 2 for driving servo 7. This can control an iris diaphragm 5 (as shown), a wedge or rotatable neutral density filter, or a perforated disc diaphragm. The apparatus is useful for line following with a bright sunlight background, and can also cope with yellowed or dirty drawings.

Title: Improvements in or relating to power presses
IPC: F16D43/26
Filed: 1925-07-25
Abstract: 258,980. Sweeney & Blocksidge (Power Presses), Ltd., and Sweeney, S. July 25, 1925. Gearing for stopping and starting machinery.- In a power press in which a crank shaft 11 can be connected and disconnected with a source of power 10 by movement of a clutch &c. control 20, a safety catch 28 is provided mounted on the control so that in addition to moving therewith it can be moved independently by hand into one of two positions. In one such position the control can be moved but the shaft 11 cannot turn, thereby protecting the operator. In the other position, the shaft 11 can be turned manually for tool-setting &c. but it is impossible to move the control so to bring in the power drive. In the arrangement shown, the clutch is a dog 12 sliding in the thickness of the shaft 11 and spring- pressed outwardly into engagement with recesses 13 in the wheel 10. The control comprises a cam 22 movable towards the clutch to disconnect. The cam is carried in a yoke 20 operated through a rod 25 by a pedal &c. The safety catch 28 is pivotally mounted on an axis parallel to the main shaft on a trunnion 27 fast upon the yoke 20 and slidable in a recess in a fixed bearing block 35. The catch 28 has a shaft-engaging arm 30 and an auxiliary arm 31 in different planes. When the drive is operative, the arm 30 is housed in a recess 46 in the block 35. When the control 20 has been moved to the position shown to disengage the dog 12, the catch 28 is carried laterally with it until the arm 30 comes into the path of a snug 40 projecting from the shaft 11. which shaft is thus prevented from overrunning, and the press slide cannot descend. The arm 30 rests upon a projection 37 upon the block 35. The catch is now in one of its positions referred to. If it is desired to move the press by hand, the catch 28 is moved to its other independent position. This is done by turning it manually so that the arm 30 is raised clear of the snug 40 and the arm 31 engages down over the end of the projection 37. This engagement prevents the return of the control 20 to allow the clutch to snap in. If in the configuration shown, that is the first independent position of the. catch, there is some drag in the clutch tending to operate the press, an inclined face 50 of the snug 40 engaging a like face on the shaft-engaging arm 30 obstructs the movement of the control 20 to clutch-engaged position sufficiently to warn the operator.

Abstract: 1333514 Dishwashing machines W A HANSEN 26 April 1972 [28 April 1971] 19346/72 Heading A4F A portable apparatus for washing glassware and adapted to be set upon a conventional sink, comprises a compartment 20 containing a rotary sprayer 30 and means such as rails 28 for supporting a tray or basket for holding the glassware, a compartment 50 projecting into the sink 14 during use and containing a submersible pump 60 for supplying washing liquid to the sprayer from the sink 14, and control means whereby the sprayer 30 is connected selectively either to the pump 60 or to the hot and cold water supply connections to the sink. After the sink 14 has been filled with water an electrical timer switch 35 is actuated to energize the pump 60 which passes water from the sink 14 into a holding tank 64 and thence to the sprayer 30. The sprayed water washes detergent from a receptacle in the compartment door 26. The filling of the tank 64 lowers the washing liquid level in the sink 14 so that a float 86 so pivots a trough 82 Fig. 3 (not shown) that the sprayed liquid is returned to the sink 14. At the end of a washing cycle the pump 60 is de-energized and washing liquid returns from the tank 64 to the sink 14 to raise the float 86 to tilt the trough (82) so that rinsing water subsequently supplied to the compartment 20 is directed to a drain. Hot or cold rinsing water is supplied via a pipe 72 when a solenoid valve 74 is opened, a sanitizer or wetting agent being added by an injector device 76. A heater 58 and a thermostat regulate the temperature of the washing liquid in the sink 14.
