Abstract: 334,909. Meindersma, W., Rutgers, M., Dijkgraaf, A. F. J., (trading as Findriven-Sindicaat). June 6, 1929. Propelling.-A paddle wheel wherein the axis of the blade describes a surface of revolution and the blade also makes half a revolution about its own axis is provided with independent and separate driving and feathering means which can be adjusted and replaced independently. The paddle 17 is ball mounted at 18 and connected at 14 with a driving pin 5 carried in a crank 3 along which it may be adjusted for varying the stroke. In addition, gears fixed to the pin 5 and to the crank pin respectively, engage a double gear 12 freely mounted on a, pin 6 carried by an arm 7 which can be set in any desired position for adjusting the phase. In this form, the blade axis traces a conical path. For movement of the axis in a cylindrical path the blade is attached directly to the driving pin 5 and is not ball mounted. In another form, the stroke variation is effected by driving the pin from two eccentrics 21, 22 adjustably supported in slides 25, 26. In this case a simple train of wheels 28, 29 is employed for the phase adjusting. In one modification, the train of wheels for altering the phase is of the bevel kind. The driving means when in the form of an electric motor may be carried by frame either fixed to the crank or by a frame which supports the blade axis. In either case the blade axis frame is pivotally mounted so that different degrees of tilt may be given to it for altering the stroke. Specifications 277,384, 294,109, and 315,996 are referred to.

Title: Testing fuel oils for harmful contamination with strong acids
IPC: G01N31/22
Filed: 1962-05-09
Abstract: Contaminated fuel oil from the crankcase of a marine engine is tested for harmful amounts of strong acid by mixing a measured volume of the oil with a measured volume of a solution of an indicator, which changes colour in the presence of strong acid, the solution of the indicator containing a sufficient amount of basic material, e.g. potassium hydroxide, so that the indicator does not change colour, and thereby indicate harmful acidity, unless the acidity of the sample of oil is such that at least 0,05 milligrams of potassium hydroxide are required to neutralize 1 gram of oil.  A preferred indicator solution contains 0,005% by weight Bromo Cresol Green and 0,0008% by weight potassium hydroxide in water.  The test may be carried out in a bottle graduated at 4,5 cc. (level A), 29,5 cc. (level B) and 34,5 cc. (level C).  The oil sample is poured into the bottle to level A, then the indicator solution to level B, and finally kerosene (or heptane) to level C.  The contents of the bottle are shaken vigorously for at least one minute, and then allowed to settle.  The colour of the bottom liquid layer is then observed by transmitted light.  If the colour is yellow or green, the oil sample has a significant concentration of strong acids.  If the colour is blue, the sample contains no significant concentration of strong acids.

Abstract: 958,793. Traffic density measuring. LABORATORY FOR ELECTRONICS Inc. May 20, 1960 [May 29, 1959], No.17948/60. Heading G1N. In a system for measuring the "traffic density" in a single traffic lane (defined as the number of vehicles per unit length of lane) each vehicle passing a sensing point applies a pulse, from a battery 10, Fig.1, of a duration inversely proportional to the vehicle speed to an integrating capacitor 17 so arranged with respect to a discharge circuit 23, 27 that the potential across it represents the traffic density. This voltage can be displayed on a meter V which may include contacts 51, 52 to provide a signal when a preset density is attained. Where the range of tyre sizes encountered on the lane under test is small a single switch, closed by the tyre of a passing vehicle as shown at 19 in Fig.1, is adequate, but where the range of tyre sizes is large it is more accurate to use two switches (Fig. 2, not shown) in series spaced apart in the direction of traffic flow by 6-12 inches to produce the pulse of duration inversely proportional to the vehicle speed.

Filed: 1936-06-30
Abstract: 477,455. Windings for dynamo-electric machines. AKTIEBOLAGET ATLASDIESEL. June 30, 1936, No. 18152. Convention date, July 8, 1935. [Class 35] [Also in Group XXXVIII] An apparatus for measuring rotational speed and acceleration comprises a tachometer generator having a field magnet 10 adapted to produce a homogeneous field and an armature 14 having a number of separate drum windings 16, the ends of which are connected to corresponding segments 17, 18 of a commutator. The arrangement is such that only those windings which at any instant lie on the homogeneous part of the field are connected to the external indicating circuit in order that the voltage generated may be accurately proportional to the speed of rotation. In a modification adapted more particularly for indicating torsional oscillations, the armature is loosely coupled by springs to a rotatable field system, the armature then moving relatively to the field in response to torsional oscillations of the armature shaft. Stops are provided to prevent the armature windings from moving outside the region of homogeneity of the field. In further modifications, a stationary armature and rotary field may be provided or the windings 16 alone may be rotated. Moreover, a stationary commutator and rotatable brushes may be employed. In order to eliminate errors due to variations of internal resistance that occur when two neighbouring windings are connected in parallel by the brushes, the generator supplies an external circuit of high relative resistance, e.g. a thermionic valve 21, Fig. 3. The valve supplies a speed indicating instrument 22 through a resistance 23, a tapping from which supplies an amplifier 26 which through a transformer 27 operates an instrument 28. The valve 26 amplifies the A.C. component of the induced voltage caused by torsional oscillations and in conjunction with the transformer produces a current proportional to acceleration and stress in the shaft. The generator may be connected directly to a cathode-ray oscillograph.
