Title: Improvements in or relating to refrigerating systems
IPC: F25B1/04
Filed: 1924-07-31
Abstract: 220,299. Carrier Engineering Corporation, (Assignees of Carrier, IV. H.). Aug. 7, 1923, [Convention date]. Aspirating - apparatus, ejector; mixed fluids cooled in diffusers.-In a closed refrigerating system preferably employing dichlorethylene as the refrigerant and comprising an evaporator, a centrifugal exhauster, and a condenser, working under a partial vacuum, an ejector for withdrawing from the condenser any uncondensed vapour together with air that has leaked into the system, comprises a baffled chamber 47, Figs. 4, 11 and 13, containing a quantity of liquefied refrigerant. The air and vapour are drawn from the condenser through a pipe 41 connecting with a pipe or coil 49 in the evaporator leading to the induced-fluid inlet of an ejector 45 that is supplied with inducing-liquid through a pipe 48 by a centrifugal pump 46 drawing from the refrigerant in the central compartment 53a of the chamber 47. The ejector discharges through a perforated pipe 58 into a compartment 53, from which air is free to escape by a pipe 50, while the mixed condensate and inducing-liquid overflow a baffle 51 into the pump compartment. The liquid in the pump compartment is free to overflow a baffle 52 into a compartment 53b from which surplus liquid is returned to the evaporator through a float-controlled valve 55. The chamber 47 is at atmospheric pressure and is initially charged with a supply of refrigerant, the condensate drawn through the ejector being sufficient to provide a liquid seal through a pipe 59 for the pump 23 and to make up losses due to leahage past the valve 55.

Title: Electronic timepiece
IPC: G02F1/055
Filed: 1974-04-26
Abstract: 1437862 Electronic watches SUWA SEIKOSHA KK 26 April 1974 [16 May 1973] 18332/74 Heading G3T [Also in Division G5] An electronic timepeice has a solid state display in the form of a transmissive ceramic (PLZT) mounted on one side of a substrate, a driving circuit therefore being mounted on the other. The ceramic contains, titanium zirconium and either lanthanum or hafnium, and exhibits light scattering or double refraction when subjected to an electric field. As shown Fig. 1, embedded in a transparent resin block 5 is a ceramic plate 1 on a metal frame 2, a linear polarizing plate 3 and a light reflecting plate 4. Fig. 2 shows an arrangement of electrodes in 7-bar display form, and which may be mounted on one or both surfaces of the ceramic plate 1. Incident light 6 passes through the polarizing plate 3 and plate 1 and is reflected by the plate 4 back through plates 1, 3. When an electric field is applied to the electrodes the plate 1 exhibits double refraction of approximately <SP>#</SP>/ 4 , and plane polarized light emanating from plate 3 will have its plane of polarization rotated through 90 degrees by the time it is reflected back to plate 3 and so will not pass therethrough. Consequently the display will appear dark when viewed in the direction of incident light 6.

Abstract: 1433802 Anti-lock hydraulic brake systems; belt tensioners ROBERT BOSCH GmbH 17 April 1973 [22 April 1972] 18337/73 Headings F2F and F2Q [Also in Division F1] A motor vehicle anti-lock hydraulic brake system has a valve block whose valves, in order to prevent locking, seal off a brake pipe leading to a wheel brake cylinder and create a relief connection for that brake pipe; a return pump 14-16 is provided for the brake fluid taken from the brake pipe and this pump 14/16 is driven through a tensioning roller 6 which itself acts on and is driven by an endless flexible power transmission 4 from the vehicle internal combustion engine assembly which transmission 4 constitutes the drive for an engine part such as a generator, fan or cam-shaft. In the preferred embodiment illustrated the transmission 4 is a driving belt between a belt pulley 3 of an-engine crank-shaft 2 and the driving wheel 5 of a cooling fan. The roller 6 is fixed on a shaft 7 journalled in a housing 8 and the shaft 7 carries a cam 9 which as it rotates drives a piston 14 of the pump 14/16 via a cam follower member 10 and a push rod 12. The push rod 12 has ball ends which engage in sockets 11, 13 in the cam follower member 10 and the piston 14 and by the ball-socket connections the housing 8 is enabled to rock on a bearing 21 under the force of a spring 23. The force transmitted from the cam 9 to the piston 14 is not significantly effected as the housing 8 rocks. The pump cylinder 16 is provided in a fixed housing 17 and has a suction connection 18 and a delivery connection 19 connected to fixed flow and return pipes. The wheel 5 may be the driving wheel of a generator. The endless flexible power transmission may be of chain construction such as used for driving an engine cam-shaft.

In the form shown in Fig. 2, a post e is loosely mounted in a hole in a bridgepiece b on the mudguard a, and is formed with a transverse hole g to receive the stay d, which is secured in the required position by a nut h on a threaded part of the post, the nut also holding the post against rotational movement. In the form shown in Fig. 3, the post i is hollow to receive a screw-bolt j, and the stay d is passed through holes in the post and bolt and secured by means of a nut m on the outer end of the bolt j. In another form, the stay is clamped against the lug or bridgepiece by a set-screw engaging a threaded axial hole in the post. In a further modification, the post is split and a nut screwing on its tapered outer end draws the split parts together to clamp the stay. In another form, two stays are clamped against opposite sides of each end of the bridgepiece.

Abstract: 1,269,814. Filtering and settling system. A. H. EPPLER. 14 April, 1969, No. 18885/69. Heading BID. [Also in Division B3] Slurry 12 in a sump 14 at the bottom of a blast chamber 6 is supplied by a pump 16 to blast nozzles 8; preferably air under pressure is supplied to the nozzle through a pipe 22 to accelerate the slury towards the work 20 which is supported on a turntable or on rods 26. A fan 28 withdraws vapour from the blast chamber 6 through a baffle 30. A rinse chamber 32 may be a more or less separate chamber inside or outside the blast chamber 6 or merely a designated area of the blast chamber; it is preferably partially segregated by a low partition 34 to withold rinse liquid, e.g. water, from the sump. When the work reaches the rinse chamber, it is acted on by high velocity jets of clear water from nozzle 36. Rinse water with entrained abrasive is collected in a float chamber 40. The float chamber may be attached to the sump 14 or separate; in either case, means, e.g. pipe 42, is provided for discharging rinse water with entrained abrasive into the float chamber and other means, e.g. pipe 44 or port 46, is provided for connecting the float chamber 40 and the sump 14 at water level, this level being maintained by a float 48 regulating a valve 50 controlling admission of make-up water from a pipe 52. A baffle 54 prevents surges to and from the sump 14. A pipe 56 leads from the chamber 40 to a pump 58 which discharges tangentially into a centrifugal separator 60. Re-useable abrasive is discharged through the lower end 64 of the separator 60 into the sump. Water and entrained fines are discharged from the upper end and pass through a pipe 66 to a settling chamber 68; any excess water returns through a pipe 70 to the chamber 40. Further settling chambers 72, 74 and replaceable filters 76, 78 are provided. A pipe 80 connects the final chamber to a pump 38 supplying the rinsing nozzles 36, so that the substantially clear rinse water is re-used. Material settling out in chambers 68, 72, 74 is drawn off through drain parts 88 or allowed to accumulate and removed from time to time mechanically.
