Abstract: 1436049 Rotary positive-displacement fluid-machines; reciprocating compressors R Z FANBERG 1 Feb 1974 [5 Feb 1973] 4748/74 Headings F1F and F1N [Also in Division F4]  In an evaporation, condensation, compression refrigeration system condensate from a receiver 52 passes through either a first expansion valve 56 to the evaporator 53, or through a second expansion valve 46 to cool the walls of the compressor 13. In a rotary vane compressor, Fig. 2 having a compression suction port 18, the coolant vapour enters via an opening 43 and passes through an elongate passage 29-35 before being injected into the compression chamber at a port 47 which is so positioned that at least one vane 17 is always positioned between the port 47 and the port 18. All the compressed vapour passes to an outlet 22. Oil for sealing purposes is introduced into the compression chamber via an inlet 50. In a pistoncylinder type compressor, Fig. 5, the refrigerant vapour passes through ducting 82-96 before being injected into the compression chamber at 97, adjacent the upper surface of the piston when the piston is at the bottom of its stroke. The vapour injected into the cylinder is then compressed upon the next upstroke of the piston. The vapour from both sources is discharged through outlet pipe 72.

Title: A change-speed gear
IPC: F16H3/10
Filed: 1931-02-17
Abstract: 361,211. Change-speed gearing. FORD MOTOR CO., Ltd., 88, Regent Street, London.-(Assignees of Sheldrick, L. S. ; 2509, Hazelwood Avenue, Detroit, Michigan, U.S.A.) Feb. 17, 1931, No. 5037. Convention date, March 22, 1930. [Class 80 (ii).] In three-speed and reversing gearing for vehicles of the kind embodying an overrunning clutch operative for direct drive and middle speed, this clutch is adapted to be locked in middle speed to allow the engine to be used as a brake. Gear 32 can be thrust into clutch engagement at 42 with a clutch end of a pinion 13 fast on the clutch shaft 14 for direct drive, or into mesh with a countershaft gear 24 for middle speed. The overrunning clutch comprises a coil 37 arranged to slide axially with the gear 32, which is mounted on a round part 29 of the driven shaft 17. The coil 37 is fastened at 38 to the gear 32 and projects into a cup member 31 slidably splined on shaft 17 and constrained by means 35 to slide with the gear 32. A gear 30 which is slid to left and right to effect low speed and reverse, respectively, carries a clutch end 45 which is used, when gear 30 is in the neutral position shown, to lock the one-way clutch. The gear 32 is connected by a sleeve 33 to a clutch end 44 which turns clear of clutch end 45 when the gear 32 engages the gear 24 during middle speed with overrunning. To lock the clutch 37, the gear 32 is moved farther to the right, while still engaging the gear 24, until the members 44, 45 engage, thereby making the gear 32 rigid with the shaft 17. This locking movement is normally prevented by a stop 58 on a selector control lever 47 engaging a fixed stop 59. To lock the one-way clutch, the stop 58 must first be purposely raised by hand against a spring 57. The expanding of the coil 37 into oneway gripping engagement is started by a ball 39 between an inclined recess 40 in the coil and a hub projection 70 of the cup member 31.

Assuming that the divisions along d<SP>1</SP>, d<SP>2</SP> each equals 0.050 inch and that each division on scales e<SP>1</SP>, e<SP>2</SP> equals 0.048 inch, the increment is 0.002 inch. If the scale e<SP>1</SP> is given odd numbers and e<SP>2</SP> even numbers, a staggered increment of 0.001 inch is obtained readable by division of 0.048 inch. The sliding jaw has a spring-pressed plunger f having a half-nut portion f<SP>1</SP> engaging a screw g in a groove along the back of the blade b rotated by a divided head g<SP>1</SP>. The plunger is released to give a quick adjustment, a fine adjustment being given by the head g<SP>1</SP>. A clamping screw is provided on the back of the slide a. There may be one of three arrangements. (1) in which the main scale is unstaggered and the vernier staggered, (2) in which both main scales and vernier scales are staggered (as illustrated) and (3) in which the main scale is staggered and the vernier not staggered. The blade b may have one scale with the divisions right across the blade which is slotted longitudinally in the centre. The vernier would then have four scales each staggered to the extent of “ division relatively to the other vernier reading on the same portion of the scale. In the case of a clock gauge, a staggered secondary scale may be provided diametrically opposite to the main scale and a single double-ended pointer used, or the main scale and one or more secondary scales may be unstaggered and two staggered pointers used.

Abstract: 1,218,313. Programmed control. HAZELTINE CORP. Feb. 3, 1969 [March 28, 1968], No.5650/69. Heading G3N. The presence of a selected notch-pattern in a moving ribbon is detected by inter-secting the ribbon with two beams of radiation and detecting the effect on the beams of radiation of the passage of an increment of ribbon bearing the selected notchpattern . As shown, Fig. 1, radiation detectors 18, 19 are responsive to beams of radiation generated by corresponding infrared sources 13, 14. The detectors sense the presence in a strip 10 of a shallow cueing notch, as shown in Fig.2a, by the reception of the beams of radiation from the sources and produces two time displaced overlapping waveforms having a signal level which is used to change the state of Schmitt trigger circuits within a logic circuit 20. The logic circuit employs AND-logic to identify the notch shape and provide a cueing output. Erasure of the cue is effected by the addition of a short notch adjacent to the cueing notch which causes rejection of the cue by the logic circuit.

Title: Improvements in or relating to the stabilisation of emulsions
Inventor: ORLEY ALEXANDER
IPC: C12G3/04
Filed: 1957-02-21
Abstract: A liqueur comprising an emulsion of 8% dairy cream, 5% egg yolk, 40% sugar, 17.1% absolute alcohol, and water is stabilized by contacting all or part of the liqueur with sheet or disc latex rubber for a time sufficient to prevent subsequent breaking up of the emulsion, e.g. at least 24 hours.  The liquer from which a proportion of the oil has separated may be treated and the separated emulsion reformed by agitation after the treatment.  An example is concerned with preparing the stabilized liqueur by mixing cream and ground solid-frozen egg yolk with previously prepared liqueur having the foregoing composition and which had been left for a week in contact with thin latex rubber sheets, in the proportions of 1/2 oz. latex rubber to 40-50 gallons of liqueur stock and one gallon of liqueur stock for each 80 gallons of freshly produced liqueur.  The mixture was agitated in a colloid mill and finally an aqueous solution of sugar and the alcohol were added in the requisite proportions.  The liqueur emulsion so produced had no tendency to break and no separation of oil was observed.
