Title: Driving arrangements for talking machines
IPC: G11B17/00
Filed: 1927-10-01
Abstract: 278,386. Wrangell, M. de. Oct. 1, 1926, [Convention date]. Driving.-Relates to a driving arrangement comprising an electric motor and a spring and clockwork adapted for alternative use, and a control device which in one position connects the motor and disconnects and locks the clockwork, and in another position releases and connects the clockwork and disconnects and switches off the motor, and consists in actuating the control from the handle for winding the clockwork spring. In one arrangement, a pulley driven from the motor and a wheel of the clockwork are freely mounted on the spindle of the governors geared with the turntable shaft, and a feathered sleeve on the spindle may be moved into clutch engagement with either by a pivoted lever which in one position locks the clockwork and in another breaks the motor circuit. Fig. 1 shows a pivoted control spindle 19 operable by a finger 21 and arranged so that movement in one direction causes a fork 28 to clutch the motor driven pulley 4 to the governor shaft and a link 27 to move a pivoted tooth 26 into locking engagement with the clockwork 39. Reverse movement of the finger 21 declutches the pulley 4, withdraws the tooth 26, and through link 24 rocks a shaft 23 so as to raise a fork 33 and clutch the clockwork wheel 2 to the turntable spindle 6 and at the same time to withdraw a finger 38 holding a spring contact 12 of the motor circuit which is thereby permitted to open. The control finger 21 is actuated from the winding-up handle which engages and drives a toothed sleeve 41 on which a cam 42, Fig. 4, and a disc 45 with upstanding projections 46, 46<1>, 47, 47<1> are loosely mounted. A. crescent-shaped recess 43 in the cam 45 accommodates a ball or roller 44 lying between the projections 46, 46<1> on the disc 45. When the handle is turned to wind up the spring it first rotates the cam, through the clutch action of the ball 44, to rock the control finger 21 against spring pressure and thereby declutch the motor driven pulley and break the motor circuit. The projection 47 on the disc 45 is thereby brought against the finger and arrested, causing the projection 46<1> to release the ball 44 so that the winding handle can continue to turn and wind up the spring without the cam and disc turning. To cut out the clockwork and reconnect the motor, the handle is turned in the other direction to rotate the cam to the position shown in Fig. 6, the finger being returned by its spring to disconnect and lock the clockwork and connect and switch on the motor. The Specification as open to inspection under Sect. 91 (3) (a) also describes an arrangement in which a pulley driven from the motor and a wheel of the clockwork are freely mounted on the spindle of the governor geared with the turntable and a feather sleeve on the spindle may be moved into clutch engagement with either by a pivoted lever which in one position locks the clockwork and in another breaks the motor circuit. This subject-matter does not appear in the Specification as accepted.

Title: Information play-back apparatus
IPC: G11B7/09

Abstract: 1532345 Automatic control of light beam focus and position HITACHI Ltd 22 June 1977 [25 June 1976 9 Aug 1976] 26176/77 Headings G2J and G3R In apparatus for playing back information recorded as a track 6 on a medium 5 comprising a laser 1 and optical means for guiding the laser beam reflected from the track on to a detector (not shown), the detector has at least four sections with an axis of symmetry parallel to the information track and the optical means includes a uni-directional focusing element 7 inclined (e.g. at 45 degrees) to the track. The detector is placed at a point below 7 at which the beam is truly circular when it is correctly focused on the track 6; at points above and below this the beam becomes elliptical in a direction dependent upon the direction of misfocus and this is the basis of a prior art system for correcting the focus. However, it is explained that due to imperfections in the track (which comprises pits of the order of 1 Ám wide, 2 to 3 Ám long and 0À15 Ám deep) the intensity may not be uniform over the reflected circular spot, giving rise to a spurious focusing error, Fig. 6 (not shown). This is avoided by the present invention by the inclination of element 7, which ensures that the non- uniformity of the intensity affects opposite sections of the detector equally, thus cancelling this "error". Focusing is achieved by movement of lens 4. Other signals from the detector are a measure of misalignment of the beam and the track and this is corrected by rotation of a mirror 16. Further signals from the detector contain the reproduced information from the track in F.M. form. In an alternative embodiment the alignment correcting system includes means for compensating for large cyclic errors due to eccentricity of the record medium, Fig. 10 (not shown).
Patent GB-600985-A (GB)
Title: A process for the manufacture of indene and indane compounds
IPC: C07C39/23
Filed: 1945-10-08
Abstract: Indene derivatives of the general formula <FORM:0600985/IV(b)/1> (wherein X represents hydrogen or an alkyl radical and R hydrogen or an acyl radical, e.g. the radical of a lower saturated fatty acid, or a benzoyl radical) are manufactured by the action of a Friedel-Crafts catalyst, in the presence of an anhydrous solvent inert under the conditions of the reaction, on butadiene derivatives of the general formula <FORM:0600985/IV(b)/2> and, if desired, esterifying any free hydroxy groups present.  The esterified products may be isomerized by heating in the presence of organic bases, thereby causing shifting of the double bond in the five-membered ring, after which the ester groups may, if desired, be removed by saponification.  If desired, esterification and isomerization may be effected simultaneously by heating the free phenolic compounds with a mixture of an organic base and an acid anhydride.  Corresponding indane derivatives are obtained by hydrogenating any of the indene derivatives produced by the foregoing reactions, and, if desired, splitting off any ester groups before or after hydrogenation. The various products possess oestrogenic properties.  In examples: (1) boron trifluoride is passed into a solution of 1 : 4-dimethyl-2 : 3-di - (p - hydroxyphenyl) - butadiene - (1 : 3) in chloroform at room temperature, producing 1 - methyl - 2 - (p - hydroxyphenyl) - 3 - ethyl - 6 - hydroxyindene, which may be esterified by heating with acetic or propionic anhydride; (2) 2 : 3 - di - (p - acetoxyphenyl) - butadiene and its 1 : 4-dimethyl derivative are similarly treated to produce respectively 2-(p-acetoxyphenyl)-3-methyl - 6 - acetoxyindene and 1 - methyl - 2 - (p-acetoxyphenyl) - 3 - ethyl - 6 - acetoxyindene; (3) the latter product of (2) is heated with pyridine to form 1-ethyl-2-(p-acetoxyphenyl)-3-methyl-5-acetoxyindene, which may be saponified with alcoholic caustic potash; (4) the non-esterified product of (1) is heated with pyridine and acetic anhydride, producing two isomeric indene diacetates; (5) the same starting material, dissolved in acetone, is shaken with hydrogen and a suspension of palladous chloride and animal charcoal in ethyl alcohol to yield 1-methyl - 2 - (p - hydroxyphenyl) - 3 - ethyl - 6 - hydroxyindane.  Aluminium chloride, zinc chloride and stannic chloride are additionally specified as catalysts and quinoline as an organic base.  The Specification as open to inspection under Sect. 91 comprises also the case in which R in the general formul\sp above represents an alkyl group (particularly a lower saturated alkyl group), which may be present in the starting materials or may be introduced by etherification of free hydroxy groups after the initial cyclization, and which may, if desired, be split off by saponification after the shifting of the double bond or after the hydrogenation.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to coin-freed calendars for coin-collecting boxes and the like
IPC: G07F17/16
Filed: 1935-09-21
Abstract: 463,315. Coin-freed date indicators. MARTIN, S. C., and CUMMIN, S. G. Sept. 21, 1935, No. 26217. [Class 27] [Also in Group XIX] A coin-freed date indicator, particularly for use with a coin-collecting box, comprises a handle 11, Fig. 3, pivoted on a shaft 10 and connected by parallel rods 12, 13 to two plates 14, 15 for changing the day-names and the day - numerals respectively. Normally, one toothed arm 5c, Fig. 2, of a bell-crank lever 5a, 5c obstructs a projection 16 on the plate 14, until a coin 4, inserted through a slot 3, moves aside the other arm 5a, when it drops down a shoot 1 to rest on the end 18b of a lever 18. When the handle is depressed against the action of a return spring, a shoulder 14a on the plate 14, Fig. 5, engages a pin 17 on the lever 18 to rock this lever and discharge the coin. A pusher 19, pivoted on one of the rods 12, 13 and connected to the plate 14 by a spring, advances through the space of one tooth a seventoothed wheel 20 secured to a cylinder 21 bearing the names of the days of the week, a resilient detent 22 preventing backward rotation of the wheel 20. The day-numeral change plate 15, Fig. 7, carries a resilient pusher 31 which moves over a cam 35 to engage with and move through the space of one tooth a thirtyone toothed ratchet wheel 32 secured to an adjacent face of a day numeral drum 30. This face is provided with twentyseven narrow notches 28 formed between twenty-eight teeth 29, a blank space or wide notch 34 being formed between the first and last tooth 29. A spring-urged stop 24, released by turning the plate 15, engages the notches 28. The width of the space 34 is such that when a month has twenty-eight, twenty-nine, or thirty days as opposed to thirty-one, the drum 30 ca,n be turned by hand by a knob 43 without affecting the rest of the mechanism, so that, on the next coin-freed actuation, the proper date will be shown. A projection 37 on the other face of the drum 30 engages and turns once in each revolution of the drum, a twelve - toothed star - wheel 39 carrying a cylinder on which are printed the names of the months. A supplementary coin shoot can be provided into which coins can be deposited without affecting the mechanism. Fraud, preventing.-To prevent the projection 16 from being released by tilting the device, an arm 8 pivoted on the same pivot as the lever 5a, 5c has a toothed projecting part 7a for obstructing the projection 16 if the apparatus is tilted.

Title: Sound line carrier particularly for the phonetic announcement of the indications of register, control and the like apparatus
IPC: H04M3/487
Filed: 1928-09-17
Abstract: 314,938. Poschl, O., and Benesi, M. July 5, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cash registers; audible indicators. - The indicators of a registering apparatus such as a cash register, weighing machine, or clock are audibly announced by means of a phonographic device comprising a carrier having sound records which are independent of one another and each forms a phonetic whole reproducible in accordance with the adjustment of the apparatus. The sound record carrier may be a cylindrical body, flat surface, endless band of flexible material passing over rollers, a disc, or a sector-shaped plate. As shown in Fig. 1, the carrier 1 is mounted to rotate on an axis 2 and has a number of independent sound records x each forming a closed circle disposed at definite distances from one another and starting from a common generatrix. The reproducer may be a sound box indicated by the needle 4 which is slidable in the direction indicated at 5. The sound records may be arranged parallel to the axis of the cylinder with two or more identical records lying close together and the needle may be caused to traverse one or other of the selected records. The means for producing the positioning and operating movements of the carrier is shown diagrammatically in Figs. 6, and 7. The longitudinal movement of the carrier 1 is effected by a spring-controlled lever 34 when a locking pin 37 is released from engagement with a tooth 38 on the carrier by the movement to the right, Fig. 6 of an operating rod 35 provided with cam surfaces 36, 41. The surface 41 co-operates with a locking pin 42 to limit the movement of the carrier in accordance with the setting of the apparatus. The rotary movement of the carrier is under the control of a cam disc 27 and a spiral spring 28. The disc 27, which is provided with rods 26 engaging the carrier, is held in normal position by a spring-controlled finger 31 and the spring 28 is wound by means of gearing 29, 30. The disc is released by means of an operating lever 32 after the carrier has been positioned. During the positioning movement the sound box 40 is lifted clear of the carrier by means of a lever 46.
