Title: Improvements in or relating to flexible fluid supply arrangements
Inventor: HALLETT JOHN EDWARD
IPC: G21C19/02
Filed: 1959-02-27
Abstract: 878,882. Handling nuclear fuel elements. GENERAL ELECTRIC CO. Ltd. Feb. 17, 1960 [Feb. 27, 1959], No. 6940/59. Class 39(4). In a reactor fuel element charging apparatus including an inner duct rotatable within a stationary housing to permit alignment of the duct with the selected fuel channel the duct carries a number of devices (not shown) operated by compressed carbon dioxide, the gas being conveyed to the duct by metallic tubing coiled a plurality of times around the axis of the duct rotation. The other end of the tubing is secured to the housing and the coiling permits the duct to rotate through 180 degrees about each side of a datum position. As shown, the duct 12 is rotatable through 360 degrees within an annular member 11 to which six gas supply tubes 1..6 are secured. Each tube is of stainless steel and extends from a coupling 13 to a clamp 15 on a support 14 fixed to the member 11, each tube then extending to a clamp 16 on a further support 17 (not shown in Fig. 2). From the clamp 16 each tube is coiled fifteen times around the duct 12 and has its other end secured by a coupling 21 to a respective one of six lugs 18 on the duct. A coupling 22 connected by holes in the lug to the coupling 21 enables gas supply leads to be taken along the duct wall by saddles 23.

Title: Process for hardening phenol-aldehyde condensates
IPC: C08L61/10
Filed: 1950-03-07
Abstract: Hardened phenol-aldehyde resins are prepared by adding to a hardenable phenolaldehyde condensate (1) from about 5 to about 40 per cent. (calculated on the hardenable condensate) of polyvinyl alcohol or a derivative in which at least 30 per cent. of the hydroxyl groups are in the free form and (2) from about 5 to about 15 per cent. of paraformaldehyde (based on the polyvinyl alcohol or derivative) and hardening the mixture in presence of an acid catalyst.  Specified phenols are phenol itself, the cresols, mixtures of xylenols, paraisobutyl-phenol, para-tertiary butyl-phenol, para-isohexyl-phenol, dihydroxy-diphenyldimethyl methane or mixtures. Specified aldehydes are formaldehyde, acetaldehyde and furfural. Specified polyvinyl alcohol derivatives are the acetals, e.g. from formaldehyde, acetaldehyde, butyraldehyde or crotonaldehyde; the esters, e.g. the acetate or benzoate; or the ethers, e.g. the methyl, ethyl or butyl ether.  The phenol aldehyde condensate may be prepared by condensation in alkaline medium or by condensation in alkaline medium followed by condensation in acid medium.  In examples (1) A phenol-formaldehyde condensate is hardened in presence of polyvinyl butyral, paraformaldehyde and paratoluene sulphochloride.  Benzyl alcohol or triethyl phosphate may be added to the mixture before hardening.  (2) A xylenol-formaldehyde condensate is hardened in presence of polyvinyl formal, paraformaldehyde, quartz powder or barium sulphate and para-toluene sulphochloride.  Specification 573,437 is referred to.

Title: Improvements to or relating to supplies for television cameras
Inventor: DONNAY JACQUES RENE
IPC: H04N3/18
Filed: 1953-03-13
Abstract: 731,989. Rectifying. RADIO-INDUSTRIE. March 13, 1953, No. 6997/53. Class 38 (2). In a method for generating high direct voltages to supply television camera pick-up tubes one of these direct voltages comprises two components in series, one of which is a high preset voltage developed over a rectifier 31, the other being a very much lower adjustable voltage developed over a rectifier 25. The low adjustable voltage is derived from the frame scanning pulses introduced at 9 which pulses have their waveform changed to sinusoidal form by a series of valves and filters, this sinusoidal voltage then being applied to the potentiometer 21, adjustment of which varies the value of the low value component of the direct voltage applied to the pick-up tube 3. The filter 27 associated with this voltage is required to introduce no appreciable delay between the time adjustment is made at the potentiometer and the time the voltage at the tube alters; it is thus designed as a low-pass high cut-off filter having a cut-off frequency of 200 cycles which is high compared with the frame frequency of 50 cycles. No such considerations apply to the filter 30 associated with the high preset voltage component, thus filter 30 is designed as a high efficiency low-pass low cut-off filter having a cut-off frequency of 25 cycles which is low relative to the frame frequency. As shown. this high preset component is also derived from the frame scanning pulses; alternatively it could be derived from a separate 50-cycle source. The high preset voltage is applied to the cathode 1 of the tube 3 whilst the two components in series addition are applied to the modulator or grid 2 thus the grid to cathode bias may be varied by adjustment of the potentiometer 21 without serious effect on the picture.

Filed: 1945-03-20
Abstract: 589,223. Movable dolls eyes. POPPER, F., and POPPER, E. March 20, 1945, No. 7040. [Class 132 (iii)] A toy animal or doll has a head formed with eye sockets 18, 19, behind which is pivotally mounted, so as to be rotatable within limits determined by stops 20 and 21 about a horizontal axis 11 normal to a vertical plane containing the eyes, a plate 10, the centre of gravity of which is above the axis of rotation 11 and which bears representations 12a and 12b (or 13a and 13b) of two eyes which are adapted, in one or other angular position of the plate, to register with the eye-sockets. One pair of eyes 12a and 12b may be looking to the left and another pair of eyes, 13a and 13b, to the right, the lines joining the pairs of eyes being inclined at an angle of about 15 degrees. Alternative pairs of representations or eyes may be placed on plate 10, e.g., one pair may be closed and the other looking straight forward. The plate may be mounted between a flat box 14 and its lid, either having two circular apertures 16 and 17 through which the eyes on the plate can be seen when in the appropriate positions. The box is glued to the inside of the face of the doll. Owing to the unstable equilibrium of the plate 10 when the doll is held in a vertical position and the lower edge of the plate is horizontal, if the doll is tilted sideways in one direction or the other a looking to the right or the left (or alternatively opening and shutting of the eyes) by the doll is simulated.

Title: Improvements relating to devices for locating conducting or magnetisable bodies
IPC: G01V3/10
Filed: 1925-03-17
Abstract: 235,526. Geffcken, R. H. H., and Richter, R. H. June 11, 1924, [Convention date]. Burglar and like alarms. -Conducting or magnetizable bodies are located by their action on the oscillating condition of a valve generator, which causes variations in the anode or grid continuous current, An oscillating circuit 4, tuned to resonance, is connected by a variable coupling 3 to the oscillating circuit 2 of the generating valve 1, to which is also coupled the grid reaction coil 5. The anode current is observed by means of a galvanometer 6 bridged by a condenser 7. The galvanometer may be replaced by a compensating circuit, for example by a resistance in parallel with a battery having a potential difference oppositely directed to the fall of potential over the resistance. A zero instrument in circuit with the battery and resistance is deflected on fluctuation of the anode current. The grid reaction coil 5 mav ba coupled with the circuit 4 instead of the circuit 2, in which case the coupling may be either inductive or capacitive. Alternatively a foreign excited valve generator may be employed. The galvanometer 6 may be replaced by a telephone, the generator oscillation being interrupted periodically at a frequency which is dependent on the strength of the grid or anode current. To effect this, the grid or anode current is blocked by a condenser shunted by a resistance. Presence of a conducting body may be arranged to influence the self-induction or capacity of the circuit 4, the coupling 3, the generator reaction coupling 2, 5, the foreign exciting frequency. &c. The invention may be employed as an alarm device on the approach of persons to estates and for examining persons leaving factories to detect the carrying away of metal objects.

Title: Follow-up arrangement
IPC: G01G23/36
Filed: 1957-03-05
Abstract: 808,549. Electric weighing apparatus. HOBART MANUFACTURING CO. March 5, 1957 [March 5, 1956], No. 7261/57. Class 40 (1). The beam of a weighing machine carries a follow-up switch consisting of two contact pairs which are both normally closed, movement of the beam opening one of the contact pairs to selectively energize relays whereby a servomotor repositions the fixed contacts, the amount of movement being indicative of the displacement of the beam, and therefore of the weight added. As shown (Fig. 1) the beam 11, pivoted at 12, is associated with a carriage 30 adjustable by the rotation of a screw 20 driven by a motor 15. The carriage has a resilient arm 35 on which are located switch contacts 36, 37, the former mating with a contact 38 attached to the carriage, and the latter mating with a contact 39 attached to the beam 11. The contact pairs are normally closed, so that relays 45, 46 are energized, the former opening switch 47, breaking the energization circuit for the armature 16 of motor 15, and the latter positioning the change-over contacts 50 associated with the field windings 17 of the motor. When a weight is placed on scale pan 10, contacts 37, 39 are opened, de-energizing both relays 45, 46, and motor 15 drives the carriage 30 until the contact pairs are again closed. When a weight is removed from scale pan 10 the beam 11 pushes the resilient arm 35 to open contacts 36, 38, whereupon only relay 45 is de-energized, and the motor 15 runs in the opposite direction to reposition carriage 30 until both contact pairs are again closed. A register mechanism 22 records the movement of carriage 30, and hence the variations in weight in scale pan 10.
