Title: Process for the continuous refining of vegetable and animal oils
IPC: C11B3/06
Filed: 1937-10-08
Abstract: <PICT:0485975/III/1> p  In a continuous process for refining vegetable and animal oils, alkali is mixed with the oil, the mixture cooled, the soap separated, the separated oil mixed with water and finally the oil is separated from the water.  The stage of cooling the mixture of oil and alkali facilitates the more complete separation of the soap.  In the plant lay-out illustrated, crude oil from the tank 1 and alkali from the tank 3 flow into the mixer 4. The soap-forming reaction starts in the mixer 4 and is completed in the plate 5.  The oil then passes through the cooler 6 before introduction to the centrifuge 7 where the oil is separated from the soap.  The separated oil is then washed with water and separated in a second centrifuge.

Title: Apparatus for regulating the elevation of vehicle headlamps
IPC: B60Q1/068
Filed: 1973-06-08
Abstract: 1430026 Adjusting vehicle headlamps ROBERT BOSCH GmbH 8 June 1973 [10 June 1972 1 Sept 1972] 27369/73 Heading F4R The elevation of vehicle headlamps is reguated by an arrangement including a supporting frame encircling a reflector pivotally mounted about a horizontal shaft, and on which shaft a pivot lever attached to the reflector is rotatably received and an actuating lever is fixedly mounted, wherein the two levers are urged together by a spring such that rotation of the shaft in response to changes in the vehicle attitude effects a rotation of the reflector, and an adjusting screw threaded through one lever to engage the other determines the basic setting of the headlamp. As shown in Figs. 2 and 3, the pivot bearing 12 comprises a bearing block 22 which is secured to the supporting frame 10 fixed to the car body 17 and which carries a shaft 23 that is positively coupled for limited torsional movement by coupling 25 to a bar 26. The other end of shaft 23 nearest the reflector 11 is splined and engages a curved actuating lever 29 clamped thereto by screw 30. A pivot lever 31 rotatably mounted on the shaft 23 is connected at one end by a plate spring 33 to the reflector 11 and at the other end receives a threaded pin 35 which is connected by a flexible shaft or cable 36 to an adjusting screwhead 37. The end of pin 35 is maintained in permanent engagement against the actuating lever 29 by a spring 41 having legs 42, 43 that act to force the levers 29, 31 together to form a positively connected unit. Thus the inclination of the headlamp with respect to the horizontal axis 14 can be set by adjusting the screw 37 to effect a relative displacement of the levers 29, 31, and, independently, correction may be made for changes in the attitude of the car, e.g. due to loading, by rotational adjustments transmitted to the shaft 26. In a modification, Fig. 4 (not shown) a coupling member (47) is pivotably connected between a second lever arm (46) of the pivot lever 31 and the plate spring 33 which is pivotably mounted by a pin (49) in the supporting frame 10 to form an articulated quadrangle. In a further embodiment, Fig. 7, the light-beam range is regulated by a hydromechanical device 75 which moves one arm 74 of a lever 83 about a horizontal pivot axis, a second arm of the lever 83 being adjustably spaced by a bolt 107 from a pivot lever 93 connected to the reflector 98 but maintained in positive engagement therewith by a clip spring 103. Further modifications in the adjustable connections between the two levers are also described, Figs. 9, 10 (not shown). The headlamp arrangement may in addition be provided with a sliding block bearing 13, Fig. 5, in which the bearing pin 53 lying along the horizontal pivot axis of the headlamp is slidable in a horizontal plane along a guideway 54. Further sliding block embodiments, Figs. 6, 11 and 12 (not shown) are described.

Filed: 1974-06-24
Abstract: 1446667 Burglar alarms FANKHAUSER GLAS AG 24 June 1974 [22 June 1973] 27966/74 Heading G4N [Also in Division H4] An alarm system for indicating breakage of a double glazed window comprises a generator 9 and an ultrasonic transmitter 7 projecting at least partially into the sealed intervening space of the window, at least one receiver 11, e.g. a microphone, arranged to respond to ultrasonic waves within or outside the sealed space, an alarm device 16, 17 connected to the receiver via a frequency selective amplifier 13. In the event of breakage, the output of the amplifier 13 will be lower than that of a reference input supplied by the generator 9 and consequently the output 15 of an evaluation device 14 becomes high to actuate, via device 16, a horn 17, warning lamps or an alarm relay to provide an indication at a central station. In a further embodiment (Fig. 4, not shown), a further receiver placed outside the sealed space receives ultrasonic waves when the intervening glass panel is broken so that the output of a differential amplifier having its inputs connected to the two receivers falls so as to operate the alarm device. In both of these embodiments a supervisory circuit automatically adjusts the level of the reference input in relation to the output of the generator 9 to avoid false alarms. In a further embodiment (Fig. 3, not shown), the receiver is placed in a room containing two or more glazed windows, each including an ultrasonic transmitter. When any of the window panels in the interior of the room is broken, ultrasonic waves received actuate the alarm device via a selective amplifier and the arrangement does not involve an evaluation circuit.
