Patent GB-652285-A (GB)
Abstract: 652,285. Calculating-apparatus. OLIVETTI & CIE SOC. PER AZIONI, C. Feb. 10, 1948, Nos. 3885 and 3886. Convention dates, March 26, 1946. [Class 106 (i)] In a calculating machine which performs multiplication by using partial products of the multiplicand with the different digits of the multiplier formed by repeated addition and/or subtraction, the multiplier is printed digit by digit by a type-bar 10 connected to the multiplier setting mechanism in such a manner that the digits are printed once only regardless of the number of machine strokes made in performing multiplication. In the machine shown, on depression of a multiplier key 1, a pin thereon engages an inclined slot in a locking member 3 to move it to the left, thus disengaging a pin 22 from a spring-urged detent lever 4. A rack 5, geared to the bar 10, is then free to move, when a lever 7 secured to the main shaft 8 is rocked clockwise, until a pin 5a engages a projection on the depressed key. The printing is effected by release of a lever 30 and the multiplier type is inclined, Fig. 3, so as to indicate whether the multiplier is to be read upwards or downwards. When the rack is restored by the return of lever 7 it is prevented from further movement, until the partial product has been formed, by a lever 15 freed from latch 25 by a cam surface 33 and engaging a shoulder 18 on the rack. The lever 15 is connected to a lever 26 which prevents further printing operations, and carries a latch 19 engaging a fixed pin 20. When the depressed key is restored the member 3 is spring-returned to the right and pins 17, 21 return the lever 15 and latch 19 respectively, and the rack 5 is re-engaged by lever 4. When the " 0 " key is depressed it rocks, through a bell-crank 23, a lever 24 which prevents totalizer engagement although a machine stroke is effected to print the multiplier digit as described above.

Title: Motor cycle safety devices
IPC: B62J27/00
Filed: 1978-08-10
Abstract: A motor-cycle is provided with a restraining pad 15 disposed to engage a rider's chest in the event of a collision and prevent his being projected forwardly from the cycle. The pad is carried on a lever 12 pivoted on the motor-cycle frame and attached to an energy absorbing device 16 whereby the force on the rider's chest can be contained within acceptable limits. The pad may be hinged to the lever so that it can be folded over the cycle saddle 8 and locked in place to deter unauthorised use of the cycle. In an alternative arrangement a pad is mounted on a strut designed to distort or deflect under the effect of impact loadings, and thus act to absorb energy. The strut may be telescopic or articulated so that it and the pad can be stowed away when not required. Cycles not fitted with a fuel tank conventionally mounted longitudinally in front of the rider may be provided with a fairing of generally similar shape to help prevent a rider slipping under the chest pad under impact forces. Padding of the tank or deflector assists to further reduce injury. <IMAGE>

Patent GB-2012422-A (GB)
Title: Apparatus and Method for Determining Velocity of Acoustic Waves in Earth Formations
IPC: G01V1/50
Filed: 1979-01-10
Abstract: To determine the velocity of acoustic wave energy propagating in formations surrounding a borehole (14), a transmitter (16) periodically transmits acoustic wave energy into the surrounding formations. This energy is received at a plurality of spaced receivers (18.1-18.4). A first portion of the signal from the receiver 18.1 is then correlated with respective first portions of the signals from the other receivers (18.2-18.4) the time reference for the correlation of each of the first portions of the signals from the other receivers (18.2-18.4) being selected, relative to the time reference of the signal from the receiver 18.1, in accordance with the spacing of the receivers (18.1-18.4) and a first estimated velocity. The correlation is repeated for four more estimated velocities, and a velocity value which yields the best correlation is selected by interpolation as a first provisional velocity. The correlation for several assumed velocities and interpolation is then performed on second portions of the signals from the receivers (18.1-18.4) to obtain a second provisional velocity. An output velocity is then determined as a function of the first and second (and possibly other similarly-generated) provisional velocities. The velocity of the compressional component and/or the shear component of the acoustic wave energy can be obtained. <IMAGE>
