Filed: 2009-06-23
Abstract: A game comprises a transparent sphere 1, 2 containing a ball 3. A number of cups having varying sizes are provided around the interior of the sphere, and the game is played by manipulating the sphere to move the ball from cup to cup in a desired sequence. Means are provided for sequentially illuminating the cups to define the sequence, and a timing unit 4 is provided for recording the time taken to move the ball between each cup, and the time taken to complete the entire sequence of cups. The puzzle may be played in two modes, a practise or 'routine' anode, and a world record challenge mode, and the timing unit uses an algorithm to generate a code which validates world record attempts in conjunction with a related internet site. There are preferably up to 12 cups, each having contacts or sensor switches for detecting entrance and exit of the ball. A particular cup may have a side entrance for permitting entry of the ball at the start of the game. The world record challenge mode may use a programmed random sequence of up to 40 cups with a weighted skill rating.

Filed: 1924-04-23
Abstract: 237,022. Axtens, R. A. April 23. 1924. No Patent granted (Sealing fee not paid). Pianoforte actions. -In an upright action, a two-armed spring is arranged in such a way that its action is .reversed during actuation of the hammer. The spring 2, Fig. 1, is secured bv a coil at its middle to the hammer-butt 4, and by its end 6 secured at 7 it normally presses the hammer away from the spring. On depression of the key, however, the end 9 of the spring passes on to the check 11, Fig. 2, shaped as shown, thus assisting to support the hammer close to the spring. On release of the key, the hammer is thrown upwards bv the spring, so that the jack 12 readily regains its position under the notch. Either end of the spring may be formed as a hook, so that the spring may be fastened together like a safety-pin anrl put out of use. The fall of the wippen is assisted by a spring 15 secured to the wippenflange at 16 and either to the jack at 19 or to the wippen. The damper is actuated by a rigid wooden arm 20 on the wippen contacting with a regulating-button 30 on the damper-tail. The damper-rods 25 may be in connected pieces. Two flat wooden or metal rails 21, 22 joined in T-form may carry the action-rails 23, 24 which are covered with emery-cloth or sand-paper. The damper lifter-rod 29 is mounted on arms 34 pivoted at 33 in alignment with the damper-rod pivots, and is actuated by members 35, 36 connected direct to the right pedal.

Title: Ramp signal generator
IPC: G11B15/48
Filed: 1973-03-02
Abstract: 1367266 Ramp generators AMPEX CORP 2 March 1973 [3 March 1972] 10312/73 Heading H3T [Also in Division G3] A ramp generator (e.g. for controlling the acceleration and deacceleration of a tape capstan motor) comprises a generator providing zero and fixed positive and negative currents in response to zero, positive and negative values of an input voltage, a Miller integrator for integrating a current dependent upon this current and feedback from the integrator output to the generator input. The diode circuit 82 provides a zero output current in response to a zero value of E in  and a positive or negative current i n1  defined by the Zener voltage of diode 18 and resistors VR n+  and VB n-  respectively when E in  is positive or negative respectively. This current is fed to an amplifier 27 to control a current limiting bridge 28 which provides positive, negative current of fixed value or zero currents to the Miller integrator 24, 25. A voltage ramp is thus produced at the output of the integrator and this diverts an increasing portion i f-1  of the current i n1  from the input of amplifier 27 until the two currents are equal, whereupon the ramp either ceases or, if the feedback resistor Ra is low, hunts about a given value. A similar ramp is produced for decreasing input signals. Provision is made for adjusting the slope, the amplitude and the mean level. The current limiting bridge may be omitted if the output of the amplifier 27 is connected via a resistor to the input of the integrator. To control a tape capstan motor the output of the integrator is applied thereto via amplifiers 42 and 43, feedback being applied via a path 45 and via a tachometer 46.

Title: Improvements in or relating to manufacture of oily condensation products
IPC: C10G50/02
Filed: 1937-04-12
Abstract: Oily condensation products are obtained by treating the crude reaction products obtained by condensing chlorinated aliphatic hydrocarbons of high molecular weght with aromatic hydrocarbons by the aid of AlCl3 or Al, with a hydroxide or an anhydrous sulphate or phosphate of Fe, Cr, or Al at above 200 DEG  C. (preferably between 250 and 300 DEG  C.) and separating the oily constituents, e.g. by decantation or filtration.  The crude reaction products of the first condensation may be allowed to separate into two layers, of which one or both may be subjected to the hydroxide or sulphate treatment.  The amount of inorganic hydroxide or sulphate added is 1 or 2 mols. per mol. of the condensing agent in the product undergoing condensation. In an example, 650 parts of chlorinated paraffin wax containing 22 per cent of Cl are treated with 1050 parts of benzene in the presence of 50 parts of anhydrous AlCl3 and the whole heated to 75 DEG  C. for 3 hours.  The reaction mass separates into two layers, the lower of which is heated with 40 parts of anhydrous FeSO4 for half an hour at 300 DEG  C.  The benzene distils off and the AlCl3 and FeSO4 form a granular solid mass.  This mass is removed by filtration after cooling, giving a red-green fluorescent oil of viscosity 200 centistokes at 100 DEG  F. Specification 473,334 is referred to.
