Title: Improvements in apparatus for automatically or semi-automatically preparing tea or other hot beverage
IPC: A47J31/30
Filed: 1948-10-26
Abstract: 660,142. Apparatus for making tea &c. DURRANI, A. M. Dec. 9, 1948 [Oct. 26, 1948], No. 37821/48. Class 129. [Also in Group XVIII] In an apparatus for preparing tea or other hot beverage, steam pressure formed by heating water in a vessel 7 forces the water into contact with the dry tea and also forces milk from a vessel in which it is contained, the final beverage being expelled through an outer annular passage. The water is heated in the vessel 7 by an electric heater 9a contained in the double-walled cylinder 9 and the steam pressure forces the water through the apertures 9b in the cylinder 9 upwards through the annular space between the vessel 7 and the cylinder 9, downwards through the annular space between the vessel 7 and the cylinder 6 where it passes through the dry tea placed on the circumferential flange 8, and then forces the milk contained in the outer vessel 3 upwards through the annular space between the cylinder 6 and the outer vessel 3 from which the beverage is discharged into the channel 4 from which it drains through the outlet 5 into a channel 14a balanced on a pivot 16 and from which it discharges into cups beneath the open ends of the channel. The cups are placed on a balance 17 to ensure equal filling and the shaft 22 carrying the pivotal point of the balance is lowered as the cups fill and causes an alarm bell to. operate.

Abstract: 709,264. Electron beam apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 31, 1949 [Oct. 29, 1948], No. 27867/49. Class 39(1) An electric discharge device comprises an envelope 13 containing a cylindrical cathode K, a plurality of control electrodes S1, &c., of gutter form disposed within an annulus coaxial with said cathode with their bottom parts directed towards the cathode and with the side faces of adjacent control electrodes approximately parallel, and a plurality of receiving electrodes 1, 2, 3, &c., alternating with the control electrodes, means outside the envelope for producing a magnetic field parallel to the axis of the cathode, means for applying a positive voltage to the conrol elecrodes and means for selectively reducing the positive voltage on any of the control electrodes in order to direct the electron stream R from the cathode to one of the receiving electrodes. A cylindrical grid G is provided for control of the cathode current and may be in one piece or may may be divided into sections equal to the number of control electrodes SI, &c. Different sections of the grid may be arranged substantially radially from the cathode K as at G8. The electrodes S3, &c., are connected by switches K3, &c., to the negative pole of the battery Ea and are directly, or over resistances R3, &c., connected to the positive pole of the battery Ea. The members R1, &c., may be impedances other than purely ohmic. The cathode K is connected to the negative pole of the battery Ea. The receiving electrodes 1, &c., are connected by resistances rl, &c., to a potential which may be the cathode potential. By a suitable choice of the voltage E5 and the impedances contained in the circuits the electron beam R may be directed to one of the electrodes S1, &c., or to an adjacent receiving electrode 1, &c., by closing the contact of the corresponding control electrode S1, &c., in a manner similar to that of the trochotron. A self-stepping cathode beam may be obtained by a suitable arrangement of the resistances R1, &c., and r1, &c. If for example the impulse current to the control electrode S5 has been deflected towards the adjacent receiving electrode and in the resistance r5 of this electrode has given rise to a sufficiently great potential drop the beam will be forced towards the next control electrode S4 which then receives part of the electron current. This current produces in its turn a potential drop in resistance R4 such that the beam is brought over to the receiving electrode 4, and then the operation is repeated for the following electrodes. The Specification as open to inspection under Sect. 91, comprises also the arrangement shown in Fig. 1 (Cancelled) in which the electrodes 1, &c., are not of gutter form, in which the switches K4 and K5 are connected to the voltage Ea through impedances R14 and R15 and in which the terminals A1, &c., are connected to circuits in which the cathode current is employed. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to delivery-boxes
IPC: A47F1/06
Filed: 1935-10-12
Abstract: 463,979. Parcel - receiving devices. DAVIES, B. E. HAMMOND-. Oct. 12, 1935, No. 28216. [Class 18] A box into which parcels can be delivered, has an insertion opening closed by a door 10 and giving access to a number of trays 4<a> . . . 4<d>, and opening and closing of the door brings the next ,tray in the series to the delivery opening until all the trays have been filled. In the embodiment shown, when the door 10 is closed, a spring-held pivoted dog 10<c> acts on one limb of and rotates a star-wheel 9 which is fixed to the shaft of a pinion 17. Rotation of the latter moves a chain 18 and, through wheels 12, 16, a chain 14 which is engaged by a lug 15 on the tray 4<a>, so that for one operation of the door the series of trays is drawn downwards a distance sufficient to position the' next tray opposite the insertion opening. The trays 4<a>, 4<b> are rigidly connected together by tubes 3 which slide on guide posts 2, but the trays 4<b> . . . 4<d> are connected by lazy-tongs 7 whose free pivots carry rollers running in guides 6<a> which open out at their upper end to ensure the trays being closely packed when empty. During the descent of the trays, the chain 18 winds up a spring 27 which lifts the series of trays to its original position after the trays have been emptied. This resetting may be helped manually by a handle 28 connected to a shaft around which the chain 14 runs. The wheels 12, 16 are formed as a clutch and, as the tray 4<a> approaches its lowermost position, a projection thereon presses on a lever which, in its turn, disengages the two elements 12, 16 of the clutch whereby further closing of the door 10 does not move the trays. A handle is provided to allow the clutch to be disengaged from outside the box. After tray 4d has been filled, closing of the door 10 lowers that tray and allows a hook 10<h>, on the door to engage a catch on the tray and so lock the device to prevent further operation thereof. The door which is acted on by closing springs 10<j> may also be provided with a separate lock. Access to the interior of the box to reset the apparatus is obtained through a hinged door 31. When the trays are in the extended position, a " full " notice on tray 4d is visible through a slot on the front of the box. Any of the operations of the device may be effected by a prime mover instead of manually. The trays may be arranged to move horizontally or rotate, or deliver goods upwards or into a shoot. The movement of the trays &c. may be indicated by a buzzer, light, &c., and recording means to count the number of operations may be provided. According to the Provisional Specification, the trays may be constructed in a framework which slides in and out of position.
