Patent GB-732613-A (GB)
Abstract: 732,613. Picture books. KUHN, H. June 11, 1953, No. 16118/53. Class 16. A picture book has parts of the pictures movable by means of driving mechanism which is shaped flat and built into the interior of each sheet of the book, the movable parts of the pictures being arranged on one or both sides of the sheets of the book. As shown, a sheet comprises a border R on which four surfaces a, b, c and d are fixed with a slight separation ; the outer surfaces a, b being transparent at least in part. The mechanism, which comprises a chain h passing round flat wheels i is situated in the space g between surfaces c, d and the surface c has holes corresponding to the hubs of the wheels i and the surface d has a slot T corresponding to the path of the chain h. The picture in Fig. 1 shows the path of a snake S into and out of its holes H which are represented by non-transparent parts B of the surface b, the snake showing through the transparent parts A. The snake S comprises a number of movable parts each secured to a link of the chain h through the slot T so that movement of the chain produces movement of the snake. The other picture, which has its moving parts in the space e between the surfaces a, c, shows a country scene with windmill, aeroplane and man sawing wood and the revolving sails and propellor are effected directly from the wheels i while the to and fro movement of the man and saw are effected by an eccentric on the wheel axle positioned inside the upper part of the body which is hinged to the surface c, the arm of the man being hingedly fixed to the body and the saw having a pin moving in a slot in the surface c. The mechanism may be operated by means of a crank K inserted from either side of the sheet into an opening o extending through the hub n of the lowermost wheel i, or a winding up spring can be built into each sheet or into the back of the book to operate the mechanism. Alternatively, a small electro-motor may be built into the back of the book having a worm in engagement with one of the chain wheels of each sheet which is disposed to protrude over the back edge of the sheet, the turning axis of the sheets being arranged to coincide with the axis of the worm so that they are always in contact.

Title: Data monitoring and recording system incorporating a real time clock using computer means
IPC: G04G99/00
Filed: 1979-02-16
Abstract: A data monitoring and recording system particularly for vehicles, includes a real-time clock circuit 62 (Figs. 2, 5) which supplies 16 Hz pulses, derived from a crystal controlled oscillator by a frequency divider network 102 (Fig. 5), to a computer module 50 (Fig. 2) for real timekeeping purposes. In addition, the divider network supplies pulses at 1 p.p.m. to a counter 112 in the clock circuit. When the computer module 50 is operative, one or more memory locations in a data memory 54 provide the real timekeeping function. When the computer 50 is turned OFF, e.g. when the vehicle engine and power supply 60 are turned OFF, these data locations are no longer operative. However information is retained therein by a stand-by battery 64 which also supplies the clock circuit at this time. The counter 112 accumulates minute pulses during the OFF period of the supply 60 and when this supply is restored the accumulated count in counter 112 is added to up-date real time counters in the data memory 54. <IMAGE>

Title: Arrangement for determining a data slicing level for a bi-amplitude data pulse signal
IPC: H04N7/035
Filed: 1979-11-12
Abstract: An arrangement for determining a data slicing level for a bi- amplitude data pulse signal comprising a framing code consisting of a plurality of data pulses forming a unique binary pattern followed by a sequence of coded data pulses. A register 30, which is initially set at zero, and a D-to-A convertor 31 provide an initial value of control voltage Vc for determining an initial slicing level. A register 19 records the framing code pattern during each framing code period as determined by a timing control element 34. The two types of error in the framing code pattern that is '1's received as '0's and '0's received as '1's are added in respective adder circuits 20 and 25 and the two totals S<1> and S<0> are summed in an adder circuit 27. A comparator 27 compares the total error  SIGMA  with a predetermined number M provided by a selector 28. Each time  SIGMA > M, a gate 29, controlled by element 24, applies a stepping signal to the register 30. The count in the register 30 is fed to an adder circuit 32 where the error difference S<0>-S<1>, as determined by a subtractor circuit 33, is added to the register count. The new register number is then fed back to register 30 to modify the control voltage Vc. <IMAGE>

Title: Hydraulic brake boosters
IPC: B60T8/44
Filed: 1980-02-27
Abstract: A hydraulic power brake valve 6 controls the supply of fluid from an accumulator 58 via chamber 75 and line 76 to working chambers 52, 53 behind master cylinder pistons 23, 43. Excessive movement of the valve spool 36 is prevented by a blocking arrangement 81. This comprises a piston 72 which is moved to the left by pressure (e.g. 100 bar) in chamber 75, so raising ball 71 to obstruct the spool 36. On failure of the pressure source, this movement is not obstructed, and the pedal 51 can move to the left to operate the pistons 23, 43 without power assistance. Loss of accumulator pressure results in piston 28 moving to the right, holding valve 62 closed so creating a hydraulic lock in chamber 63, so that the piston 43 moves with the input rod 42. <IMAGE>
