Title: Bell-ringing engine
IPC: G10K1/34
Filed: 1985-05-10
Abstract: A bell ringing machine having a reversible drive motor for a pendulatingly driven bell has a control device which switches the drive motor on and off for variable time or distance sections during one or both half oscillations of the bell. At the same time, after starting up, the steady state of the bell is maintained by reducing the electrical energy fed to the drive motor by shortening the switch-on time or the switch-on path per oscillation. In order to maintain the bell deflection angle corresponding to the optimum intonation in the steady state regardless of the current operating conditions at all times, a setpoint value is specified for the deflection angle in the steady state. When this angle is reached, the energy loss needed by the oscillating system to maintain the setpoint value of the deflection angle is determined and the reduced electrical energy fed to the drive motor is adjusted to it. <IMAGE>

Abstract: An allylamine derivative of the formula 
  
where R₁ = H or CH₃, R₂ = 4-methyl-pentyl or-OCH₃, R₃, R₄ = 
1-4C alkyl or 5-8C cycloalkyl and R₃ can be H, and R₃ + R₄ can

(Y)L]⁺X⁻ where Y = ethylene, 1,3-butadiene, cycloxadiene, 
cycloactadiene or L; X= Cl O₄, BF₄ or PF₆, and L is a 
binaphthyl derivative of formula 
  
where R = H, -CH₃ or tert-butyl, so as to isomerise the 
double bond (a) to the position (b) to form the corresponding 
enamine; if R₃ = H, hydrotropy tautomerism occurs at the 
CH₂-N-Y-group to form the imine.  
     The preparation of the catalyst is described.  
     The reaction is preferably carried out in a solvent such as 
an ether, ketone or halide at 80° to 120°C for 1-15 hours using 
1:2,000 to 1:10,000 mole catalyst per mole of derivative (I), 
followed by distillation off of the solvent.  
     The products are obtained in high yield and of high 
optically active purity.
Patent EP-0180467-A3 (EP)
IPC: G11C11/401
Filed: 1985-10-30
Abstract: A single-array memory employs a novel storage cell pro­
viding dual read/write access via either an «A»-side or a «B»-­
side. The storage cell uses a unique circuit in which read cur­
rent is borrowed during writing into the cell. Asymmetrical 
read/write delay circuitry is provided to avoid overwriting the 
contents of a storage cell during the read-to-write transition. 
Row-selection decoders use Schottky-clamping diodes in a 
way which provide an equivalent oscillation-damping capaci­
tance at the base of the selected-row driver transistor. The 
single-array memory can be advantageously used as part of a 
single-chip VLSI four-port register file permitting simultaneous 
reading and or writing of registers from any of two read ports 
or two write ports, respectively. Unidirectional busses connect 
each storage cell to each of the four ports.

Title: Mounting of race rings
IPC: F16C33/58
Filed: 1986-04-17
Abstract: A mounting assembly for bearing races is provided which enables split races for roller bearings to be fixed on a bearing member in a space-saving system wherein the bearing member includes at least one race groove parallel to two expanding grooves such that narrow webs are left on either side of the race groove. On assembly, for example, of the inner ring of a roller bearing in the race groove, these webs are flanged or crimped against the bearing end faces such that two ends of the axially split bearing race are securely held by appropriate profiling or beveling of the end faces of the race. Assembly may be carried out by inserting a crimping wheel into the expanding grooves and crimping the webs by means of a conically deforming surface. The mounting can be advantageously applied, for example, in connection with an eccentrically drilled bearing bushing for the plain bearings of blanket cylinders in offset printing machines.

Patent EP-0261304-A3 (EP)
IPC: E06B9/32
Filed: 1987-04-22
Abstract: Herein disclosed is an actuator for actuating an vertical 
blind or curtain of electric type to be mounted on a mounting 
support face. The actuator is enabled to eliminate the de­
formations such as torsions of rotating rods thereto to ensure 
their rotations by driving the two ends of each of the rotating 
rods with the torques of a pair of motors. The tension to be 
applied to a traverse rod can be easily adjusted to an ap­
propriate value by fastening a nut on a tensing threaded rod 
connected to the traverse rod to tense the traverse rod. Rota­
tion transmitting means can be held in position in a pivotal 
state even if the tension is applied to the traverse rod. Since 
the traverse rod is fitted in a bearing by the face contact be­
tween ridges and corners, moreover, the rotating torque is 
dispersed to enhance the breaking stress at the fitted connec­
tion.

Title: Friction welding
IPC: B23K20/12
Filed: 1987-12-08
Abstract: In a known method of friction welding two workpieces together, one workpiece is reciprocated relative to the other while the workpieces are pressed together. When sufficient frictional heat has been generated, relative movement is caused to cease and the workpieces become welded. Apparatus for carrying out that method comprises power-driven reciprocatory means (5;5 min ;10;10 min ;9;12;11) which carries the reciprocating workpiece. To balance the reciprocatory means there are counterweights (20;21;27) which move in the opposite direction to the reciprocatory means. Each counterweight is constrained to guide means (98) to move along a rectilinear path. Each counterweight is coupled to the reciprocatory means by reversing means, which comprises a pivoted rocker (14;15;24), first linking means (16;17;25) and second linking means (18;19;28). Each linking means may be constituted by a flexible blade which is anchored in a non-pivotal manner to the reciprocatory means, the rocker or the counterweight, as the case may be.
