Reservoir pens.-In a self-filling fountain pen provided with a retractable nib, the cap is provided with a semicircular hole at the front end and is connected with the spirally-slotted propelling-sleeve for the nib in such a way that, after the retraction of the nib is complete, further rotation of the - cap closes the opening at the front end of the barrel. The nibcarrier 2, Fig. 4, is provided with a pin 8 which extends through the spiral slot 9 in the relatively rotatable sleeve 1 and'through a longitudinal slot in a sleeve 19, Fig. 2, into a longitudinal slot in the wall of the covering-cap 22. The longitudinal slot in the cap terminates in a slot 25, Fig. 8, extending half way round the interior wall. The cap 22 and the sleeve 19 are each provided with a semicircular opening at the front end through which the nib is projected'. The sleeve 1 ends in a bearing 12 rotatably mounted in a ring 14 to which the cap 22 is screwed, the ring being held in position by a nut 17 carrying the sleeve 1. Rotation of the ring 14 when the nib is in the projected position causes the rotation of the sleeve 19 and the nib-carrier 2 through the engagement of the pin 8 in the slots in the sleeve and' cap, to retract the nib. At the end of the inward movement of the nib, the cap is - allowed free rotation through the engagement of the pin 8 in the slot 25, so that the semicircular holes in the front ends of the cap and sleeve 19 are brought out of alignment. The nib-carrier 2 is hollow and is connected by a tube 5 to a reservoir 6, which may be in the form of a collapsable sac protected by a cap 29, and a tube 26 provided with an opening 27 to enable the sac to be compressed. The Provisional Specification also describes a pen having the nib-carrier extended rearwards and provided with a pin engaging a spirally-slotted tube, which is provided with a rotatable. A sleeve is mounted in the front end of the barrel, and is formed with a longitudinal slot which is engaged by a second pin on the nib-carrier, the pin also extending into a longitudinal slot terminating in a semicircular transverse slot in the barrel. The barrrel and sleeve are formed with semicircular holes in the front end, and at the end of the inward movement of the nib-carrier, further rotation of the head-piece, causes the rotation of the nib-carrier and of the sleeve to close the opening in the end of the barrel. In order to prevent leakage, a screw-threaded connection may be provided to enable the sleeve and barrel to be clamped together in the closed position, or the nib-carrier may be provided with a hole which registers with a hole in a sleeve only when the nib is projected. Reference has been directed by the Comptroller to Specification 8198/03.

Patent GB-408780-A (GB)
Title: Improvements in or relating to the cooling of liquid milk products, and other liquids after heating
IPC: A23C3/04
Filed: 1933-02-10
Abstract: In cooling down after heating liquids which contain substances which undergo a physical change of state in the cooling, the liquid is cooled to a temperature below that at which the change of state occurs, the cooling is interrupted to allow the mixture to assume its new physical state at an average temperature below that at which the change occurs, and the cooling to the desired low temperature is then completed.  The first cooling may be to a point considerably below that at which the change occurs and may be to or near the final low temperature.  The cooling is carried out by passing the liquid in a stream or streams through channels or over surfaces in the cooling apparatus.  The process is applied particularly to processes for preserving liquids containing fats including cream and other milk products of relatively high fat content or other liquids containing proteins, the solidification of the fat causing a rise in temperature whilst cooling down after pasteurizing or other heat treatment.  In the treatment of the artificial cream prepared by heat treatment, e.g. at 134-194 DEG  F., of a mixture of 40 per cent fat and 60 per cent milk and an emulsifying agent, e.g. egg yolk, the mixture is passed through a heat exchanger and rapidly cooled to a temperature considerably below that at which the fat solidifies, e.g. 39 DEG  F., and then allowed to stand for say 20 minutes, during which time the temperature will rise to about 55 DEG  F.  The mixture is again led to the heat exchanger and cooled, e.g. to 34 DEG  F., and then led to a container and kept in cold storage.  The process may be made continuous by leading the liquid in succession through a heat exchanger, a holder and the same or another heat exchanger.
