Patent DE-2730606-A1 (DE)
Title: Vibration reducing mounting for living or working module on vessel - has elastic insert element between conical bodies with flange and rim which cooperate on insert failures
Inventor: SOBOTTKE NIKOLAUS DIPL ING
IPC: B63B15/00
Filed: 1977-07-07
Abstract: The vibration reducing mounting for living/working quarter modules on vessels or structures with continuously running machinery includes an elastic insert (3) between two parallel conical surfaces. Relative movement of the cones is limited by stop bolts. The mounting flange (7) of the base cone (1) has a tapering rim around most of its periphery, and the module cone (2) includes a taper-edged flange around its base. In the event of insert failure, the tapers (31, 32) mate and convert the mounting into a rigid one.

Patent DE-2733351-A1 (DE)
Inventor: SHIDA MASAHARU
IPC: H02P8/02
Filed: 1977-07-23
Abstract: In an analog electronic watch having a calendar display the power required during change of the calendar display, about 6 hours out of 24, is greater than at other times. In order to effect economy in power consumption, the pulse for driving the watch motor during the time other than the period in which the calendar display is being changed is only sufficient to drive the time indicating means. In case the motor fails to step when such pulse is applied, this is detected by a detecting circuit and a corrective drive pulse is applied to the motor so as to drive it.

Title: Metering lock chamber - for purifier oxide(s) with star wheel and conical inlet
Inventor: EBERLE SIEGFRIED-HELMUT DIPL C
IPC: C02F1/68
Filed: 1977-10-05
Abstract: In parent patent, a metering lock chamber for the pump transfer of the purifying material from one agitator or fluidised bed reactor to another is described. A star wheel inside a housing is fitted with vanes which take the material from the inlet to the outlet. The drive shaft is sealed in the housing and is driven by a motor. This enables a transfer to be carried out without having to stop the fluid counterflow which might lead to settling and clogging of the purifying material. This material can now be transferred continuously.

Title: Single-phase async. electrical machine - has starting choke and capacitor designed to increase starting torque using shared iron core
Inventor: AKBAR SAMY DIPL ING
IPC: H02P1/44
Filed: 1977-11-04
Abstract: The single-phase asynchronous machine is designed so that the presence of the starting choke increase the starting torque instead of reducing it. The starting winding (2) is connected via the starting capacitor and the coil (4) of the choke to the supply (U). The choke consists of two coils (3, 4). One of the coils is connected in parallel with the capacitor and there is a shared iron core (5). The second coil (4) and iron core form an inductance. Because the inductance is in series with the capacitor it increases the voltage across it and thereby increases the torque.

Title: Direct heating of sulphuric acid soln. - using electric current passed between electrodes immersed in the soln.
Inventor: PETERSSON STIG ARVID
IPC: C01B17/88
Filed: 1977-12-08
Abstract: Direct heating of a soln. of H2SO4 is effected using a current passed between electrodes immersed in the soln. The surfaces of the electrodes are subjected to a passivation pre-treatment, so that the resistance of transition between the electrodes and the H2SO4 soln. is at least as high and pref. 3-5 times the resistance produced by the H2SO4 soln. Used e.g. in the distn. of H2SO to increase its concn. or to eliminate dissolved impurities. Process gives a better thermal transfer and thermal yield than prior indirect processes. Owing to the high resistance between the electrodes and the liq. the process also requires a lower current intensity and therefore simpler electrical appts. than previous direct processes.

Title: Circuit for fluorescent lamp operation - has diode in higher potential lead between transformer and lamp filament for increased lamp life
Inventor: KREUTZER PETER
IPC: H05B41/232
Filed: 1977-12-14
Abstract: The fluorescent lamp's current can be below or above the nominal current. A diode is inserted between a heating transformer's or a stray field transformer's heating winding and the lamp's filament.

Title: Control circuit for cigarette making machine transporter - selects actuating pulses for acting on transported cigarettes and filters
Inventor: KOCH FRIEDO
IPC: B65B19/28
Filed: 1978-02-17
Abstract: The control and actuating system is used in cigarette making industry, for cigarettes and filter plugs transported along a production machine. The transporter path operations are controlled by control signals which are delayed synchronously with the transport of the items. The interaction is ensured with precision even at high transporter speeds. A sequence of timing pulses are triggered while the items are transported through the successive transporter sections. A pulse is selected which controls the starting of the control signal active stage. This selected pulse ensures synchronous delay of the control signals. When the items have reached the point of interaction then the control signal becomes effective. Another pulse is selected for ensureing termination of the action of control signals.

Title: Pleat dyeing process - uses printing paper placed on folded pleats to be activated by heat and pressure
IPC: D06P5/00
Filed: 1978-02-20
Abstract: The process to pleat dye a fabric, such as for a sun pleated skirt, uses a pleating form to hold the folded fabric together. Thermo printing paper is laid on the visible edges of the folds, so that the dye side lays on the folded pleats. Pressure is applied to the reverse side of the paper, together with heat. The process allows fabric sections to be produced which are pleated and dyed, while in pleats, to be made up into distinctive pleated skirts.

Title: Press control for stamping steel strip - has pneumatic nozzles to ensure correct positioning of strips fed singly
Inventor: PASSOW ERICH
IPC: B21D28/24
Filed: 1978-04-06
Abstract: Heavy gauge steel strip is supplied in straight lengths, fed into stamping presses one at a time. To ensure that the strip is correctly in position before stamping the required article, the strip (S) passes between two air nozzles (25) and interrupts the air flow. This interruption of the air flow actuates a pneumatic control system which allows the press to be started. The device also stops the press before the nd edge of the strip (2) reaches the punch (4) so that there is no danger of there being insufficient material to stamp out a complete part.

Title: Large room or cooking equipment waste heat utilising appts. - uses heat exchanger and chiller to evaporate water for cooling
Inventor: MOLITOR VICTOR D
IPC: F28D21/00
Filed: 1978-04-11
Abstract: Gaseous source of waste energy, including heat, is passed through a gas to liquid heat exchanger and then a chiller to agitate a water bath and produce evaporation of water for cooling. The heated transfer liquid is passed through a heat exchanger to heat makeup air while, alternatively, chilled water from the chiller is pased through the heat exchanger to cool the makeup air. The source of waste energy, including heat, is normally a grease extraction ventilator mounted to receive fumes and heated air from cooking equipment. Alternatively heated air which has risen to the upper portion of a large room or enclosure, such as an auditorium, theatre, meeting hall is used. The heated air removed from such a position is adapted in part to be recirculated, but all of it may be used to furnish heat for heating fresh makeup air.
