Title: Improvements in coffee making machines
IPC: A47J31/42
Filed: 1923-05-22
Abstract: 209,665. Cappelli, V. May 22, 1923. Infusing-machines. - In a coffee-making machine of the type comprising a roaster which is automatically emptied as soon as the beans have lost a certain proportion of their weight, a grinder, and an infuser, the roaster is raised and emptied by means of a spring, the tension of which can be adjusted; improvements in the infuser are also described. The roaster is mounted on a spindle 6 driven by the gearing shown and mounted at one end in a bearing carried by a lever 15 attached to a helical spring in a casing 18. The tension of the spring can be regulated by means of a screwed cap on the casing 18. A spring pin 37 on the lever 15 enters a recess in the casing of the machine, from which it is withdrawn when the difference between the tension of the spring and the weight of the roaster reaches the desired value. The roaster then takes the position shown by the dotted lines and discharges the roasted beans to a grinder 12, whence they pass to an infusing-vessel 22 supported on screws 30 so as to be easily removed for cleaning. The roaster is heated by a lamp &c. 4 which also heats a boiler 3. From the boiler a pipe 23 leads to a strainer 29 at the bottom of the vessel 22. When the water boils the water is forced by steam pressure through the pipe 23 to the coffee; when the lamp is extinguished the steam condenses and the infusion is drawn back into the boiler, whence it can be drawn off by the tap 28. The boiler 3 may be used without the remainder of the apparatus by attaching to the tap 28 a receptacle for enclosing ground coffee.

Abstract: 751,159. Clinometers. BUTTOLPH, R. Q. May 10, 1954, No. 13590/54. Class 97 (2). [Also in Group XXI] An instrument for measuring and recording the earth's magnetic field in, and the inclination of, a borehole, and the orientation between the instrument and a drill string through which it is lowered and in which it is positioned for operation comprises a casing 90, the lower part of which projects below the drill string when an enlarged portion 100 of the casing 90 engages a seat 101 formed in the bore of the drill string. In the lower portion of the casing 90 is a magnetic needle 92 and a plumb bob 93, whose position in respect to a reference mark is recorded by a camera 94. The orientation between the instrument and the drill string is determined from the photographic record made by a camera 122 of the position of magnetic needles 110, 111 in the upper part of the casing 90 when under the influence of magnets M. The magnets M are located diametrically opposite each other in the drill string and opposed poles face each other. A record is also taken of the position of a ball 120 on a convex surface and of a plumb bob 121. The record taken by the camera 122 can be related to that of the camera 94, because it shows a reference mark 130 disposed vertically above a mark 105 recorded by the camera 94.

Title: Improvements in and relating to measuring instruments
IPC: G01R17/08
Filed: 1961-04-14
Abstract: 924,102. Measuring electrically. ANSCHUTZ & CO. G.m.b.H. April 14, 1961 [Nov. 29, 1960], No. 13599/61. Class 40 (1). The invention relates to instruments of the type in which a measuring coil 1 (in this case a crossed coil arrangement determining the ratio between the currents in two coils) responding to a control torque is supported by an elastic member 6 in a measuring head 13, movement of the coil being sensed by a device 10 so that the head is driven by a motor 8 into alignment with the coil. The coil position is then readable on an indicator disc 13. According to the invention errors in the reading due possibly to residual torques in the suspension are eliminated by means of an adjusting device between the indica. tor disc and the suspension support 7. As shown in Fig. 2 this device is a screw and spring arrangement mounted on the indicator disc so as to rotate the suspension relative to it. In a further embodiment (Fig. 7) the indicator 6 is locked relative to the suspension by an electrically energized magnet 26 which inserts a pin into cam 22, the point of insertion being adjustable by screw 16. The error to be removed is determined first by removing both the controlling torque and the resetting drive and then switching on the resetting drive. The amount of movement of the indicator member is then an indication of the back setting angle to be inserted by the adjusting device. The relative positions of the sensing device and measuring coil may be determined by a pair of photo-cells providing a balanced input to an amplifier when the two members are aligned.

Title: Method and arrangement to regulate the fat content in cream when separating milk or cream continuously
IPC: A01J11/10
Filed: 1951-06-08
Abstract: 695,506. Measuring resistance and physical qualities. AKTIEBOLAGET SEPARATOR. June 8, 1951 [Dec. 29, 1950], No. 13638/51. Addition to 665,647, [Group I]. Class 37. [Also in Group I] In an improvement in or modification of the invention according to the parent Specification the cream concentrating power of the separator is regulated by means of a Wheatstone bridge so that the ratio of the specific electric resistances of cream and skim milk discharged from the separator corresponds to a desired ratio found empirically. As shown in Fig. 2 a Wheatstone bridge is set up having resistances R1, R2, the latter being variable and both such that their ratio is the same as the ratio of the specific electric resistance of skim milk and cream empirically determined corresponding to the required fat content, the other two arms being comprised by two equally calibrated measuring cells, R3, R4 through which the skim milk and cream respectively pass. The separator is adjusted until the galvanometer G shows no deviation when the fat content of the cream will be that required. In another modification, shown in Fig. 3, resistances R3S, R3G (the latter being variable), which can be alternately connected and such that their ratio is the same as the ratio of the specific electric resistances of skim milk and cream with the desired fat content are arranged to be connected at the same time as the equally calibrated measuring cells R4S, R4G respectively through which the skim milk and cream passes respectively. The bridge also comprises resistances R1, R2, the latter being variable. R4S and R3S are first connected and R2 varied until the galvanometer deviation is nil, R4S and R3S being then disconnected. R4G and R3G are connected and if deviation is now not nil the separator is adjusted until a zero deviation is obtained when cream with the desired fat content is obtained. Further modifications similar to the above but having an A.C. source of supply and another corresponding to Fig. 3 with an A.C. supply but having only one measuring cell through which the skim milk and cream passes alternately are also described.

A heat exchanger plate has a plurality of sinuous corrugations 22, 23 extending over the central portion 21 of the plate. The rectangular plate shown has along two opposite sides a pair of ports 12, 13 and along the other two sides a pair of ports 14, 15. A gasket 20 (see Specification 1,035,170), extends around the periphery of the plate and also completely surrounds the ports 12, 13 isolating these from the central zone 21 of the plate. In a plate stack forming a heat exchanger, alternate plates are as shown (i.e. with the corrugations extending generally parallel to the ports 12, 13), and the intermediate plates are similar but have the corrugations generally parallel to the ports 14, 15. Alternate plates in the stack are turned through 90 degrees whereby in all the plates the corrugations extend in the same direction and in each plate, each pair of ports is aligned with the other pair in the next adjacent plates; e.g. 12, 13 of one plate are aligned with 14, 15 of the plates on either side thereof. Two sets of fluid passages are thereby formed in the stack. In one set of passages one fluid flows in a turbulent manner along the corrugations and in the other set of passages the other fluid flows in a turbulent manner across the corrugations.
