Title: Guide post for cup spring or nest of springs - consists of bush which expands to fit bore of springs
IPC: F16F1/32
Filed: 1975-02-05
Abstract: The use of a bolt as a guide-post for a nest of cup-springs present considerable expense of manufacture to achieve the necessary hardness, surface finish of the shank and dimensional accuracy. The latter is particularly stringent in the case of "friction arm" cup springs, where play between the guide and the spring will reduce its vibration resistance. To overcome these problems, a guide post is proposed which is in the form of a bush (3), pressed into a hole in the mounting plate (4). The bush may be so dimensioned that it is conical in the free state, becoming cylindrical when it is fitted.

Title: Operating circuit for pulsed reflected light beam monitor - generates light beam pulses and detects reflected beam in single phase-locked circuit
Inventor: PRIEBSCH DIETER
IPC: G01V8/12
Filed: 1976-07-13
Abstract: An operating circuit is for use with a reflected visible or invisible light beam monitor. It is insensitive to other light disturbances and uses an interval phase locked loop to relate the generated light beam pulses and the reflected returning pulses. The central integrated circuit (1) consists of an oscillator (2) producing a rectangular waveform and driving an amplifying and differentiating stage (8) which, in turn, feeds a l.e.d. (9). Reflected light is detected by a phototransistor (11) which feeds a phase comparator (4) via a differentiating capacitance. This comparator is also fed by the original signal, and the output affects the original oscillator (2) frequency to form an overall phase locked loop with high immunity to external disturbances.

Patent DE-2646456-A1 (DE)
Inventor: BOBE JOACHIM ERNST RUDOLPH
IPC: B29C59/00
Filed: 1976-10-14
Abstract: The embossing of the foam layer is performed by pressing it against at least half of the circumference of the surface of a rotating, heated embossing roller. The surface of the support roller is kept at a temperature of 120 to 150 DEG C, and the contact pressure required for achieving the desired embossing effect is generated by tension in the carpet. The process permits the embossing of a foam layer already laminated with a carpet, although the embossing temperatures usually used for the embossing of polyurethane materials lie above the softening point of the synthetic fibres contained in the carpet. By regulating the tension of the carpet, the contact pressure of the foam layer against the embossing roller, and consequently the depth of the embossing, can be varied. Further simple possibilities of variation are obtained by changing the temperature of the embossing roller surface in the specified region. For this case, the circumferential speed of the embossing roller, dependent on the roller diameter, is to be adapted correspondingly. This can take place by increasing or reducing its number of revolutions. It is also possible to vary the length of the contact zone which is passed through by the foam layer resting on the surface of the embossing roller.

Title: Beta:lactose prodn. - by adding specified amt. of water to alpha:lactose and heating under pressure
Inventor: ASANO YUSUKE
IPC: C13K5/00
Filed: 1976-12-06
Abstract: A small amount of water at the top of the cylinder (pref. 2-15% basing on the amount of lactose) is added to alpha-lactose or the material containing alpha-lactose, and the mixture is injected under pressure from an extruder (pref. screw extruder). The temp. of the mixture at the top of the cylinder is elevated to 100-200 degrees C under k-40 kg/cm2 pressure by the frictional heat and heat of compression, and alpha-lactose is thus converted to beta-lactose. Obtained beta-lactose or beta lactose containing product may be dried and crushed if necessary. If the amount of water to be added is over 15%, injected beta-lactose which is once generated by the conversion from alpha-lactose, becomes muddy and turns back to alpha-lactose again if it is allowed to stand in such state. If the amount of water is 4-7%, the injection may be performed smoothly and injected product containing beta-lactose is the slurry containing only small amount of water, and this water is evaporated at once and the amount of water is reduced to 1-5%. Therefore, the conversion back to alpha-lactose may be hardly caused. The process may be useful for the preparation of the raw material for modified powder milk, baby food, and health diets. The product is, moreover, superior in the crumbling resistance and binding power as well as in the sweetness, therefore, it serves quite well for the improvement of bulking agent for tablets of medicines.

Title: Capacitive motor braking circuit for washing machine drum - locks drum opening in loading position without mechanical brakes (SW 23.1.78)
Inventor: GLOECKNER ERHARD DIPL ING
IPC: D06F37/30
Filed: 1977-03-24
Abstract: A control mechanism for a washing machine in which the drum is loaded through aligned holes in the cabinet and the drum, includes a single phase capacitor motor, which has an additional speed of rotation, slower than the washing speed. This makes it possible to stop the drum in its loading or servicing position. In order that the braking action is initiated at a given working speed, the auxiliary winding of the single phase induction motor may be connected into the feed current line in parallel with the main winding, by means of a switching device, and the capacitor connected in series with the auxiliary winding can be sort circuited or isolated. A switching device which can be started and stopped rhythmically is fitted for stopping the drum at the loading point. The rhythmical starting and stopping of the switching device is arranged in such a way that the motor reaches a working speed higher than the speed of unhooking or reversal when it works without there being any braking action. The feed current from supply may be linked to the parallel circuit formed by the main and auxiliary winding via a rectifier. A diode is fitted in one of the lines feeding the parallel circuit. The switching mechanism is a short circuiter connected in parallel with the capacitor. When the capacitor is short circuited, the auxiliary winding connected in series which with the resistance, is connected to the feed circuit in parallel with the main winding via the short circuiter.
