Title: Improvements in Electrical Switches.
Inventor: BENJAMIN REUBEN BERKELEY
IPC: H01H23/16
Filed: 1919-01-17
Abstract: 126,607. Benjamin, R. B., and Nilson, A. N. May 4, 1918, [Convention date]. Holders.-A lever-operated snap-action switch suitable 'for a lamp-holder comprises the usual insulating-body 40 carrying a stamped U-shaped metal switch-frame 68 held by ears thereon which extend into recesses in the body and supporting the pivot pin 60 for the U-shaped contact-member 53 and for the operating thumb-lever 54. The quick action is produced by a spring round a pin 61 hinged to the inner end of the operating-lever and passing through an opening in the closed end of the contact-member, the ends of the spring bearing on an abutment on the pin and on the contact-member, respectively. When the thumblever is actuated, the mechanism is taken over a dead-centre position and a snap-action is given to the contact-member. The part of the pin 61 which passes through the contact member is flattened out so that it cannot be withdrawn therefrom and in the extreme positions of the contactmember the leve.rs form a locked linkage whereby the impact strain due to the quick-action is borne entirely by the linkage mechanism. The switch is shown in a screw-type lamp-holder in which the central abutting contact 42 and the fixed switch contact 52 are secured together and both secured to the body by a screw pin, the screwed shell 41 being connected to one of the terminals and the other fixed switch contact to the other of the terminals, both terminals being accessible from the side of the casing by reason of the cutaway construction of the insulating-body. An insulating-disk is placed over the body and the cap 72 forced on the shell, struck up crescentshaped projections on the inside of the cap detachably engaging semicircular openings in the yieldable sides of the shell. In a modified arrangement, the terminal plates have the portion carrying the terminals bent through a right-angle. The switch frame which carries the pivot 60 may have a front plate with an opening through which the quick-action pin 61 works and ears at the top and bottom to limit the movement of the contactmember instead of using the locked linkage arrangement described above. In another arrangement, the bent-over end of a metal stamping constituting the pin 61 takes a bearing in a recess in the operating-lever which has another cut-away portion, the shoulders of which engage a lateral projection on the switch frame to limit the movement of the operating-lever.

Title: Improvements in or relating to punching tools
IPC: C14B5/02
Filed: 1947-01-14
Abstract: 620,272. Hand punching-tools. MABY, P. G. Jan. 14, 1947, No. 1262. Convention date, Jan. 16, 1946. [Class 31 (ii)] A hand tool for punching out washers comprises a holder on to which the inner and outer annular cutting members are screwed, directly or indirectly, by individual threads, so that one cutting edge is rotatable in its threads independently of the other, which facilitates removal of the cut washer from the tool. The thread for the outer cutting edge is preferably coarser than that for the inner; or one thread may be right-handed and the other left-handed. In Fig. 1, the outer cutting member 3 and inner member 5 are separately screwed on to the holder 1 by coarse and fine threads respectively, and each may have shaped portions as at 9 or 25 for engagement by a spanner or like tool. The cut washer is ejected by the spring 11, but if this is insufficient, partial rotation of the outer member 3 frees the washer so that the spring can eject it. The centre portion of waste material is ejected by the spring-loaded plunger 6. In a modification, Fig. 5, the inner cutting member 5 is screwed on to a bushing 14 instead of directly on the holder, and there are outer and inner washer ejecting springs 11, 15, and outer and inner waste ejecting springs 18, 21, in addition to the spring-loaded plunger 6. In a further modification, Fig. 5, the outer cutting member 3 is screwed on to the inner member 5 and the latter is screwed on to the holder and has a knurled portion 24; alternatively, the inner member may be screwed into the outer and the latter screwed on to the holder.

Title: Analysis of data
IPC: G01N22/00
Filed: 1971-01-12
Abstract: 1373961 Integrating apparatus CAMBRIDGE SCIENTIFIC INSTRUMENTS Ltd 10 Jan 1972 [12 Jan 1971] 1344/71 Heading G1J [Also in Division G4]  A signal representative of the true area under a humped curve whose flanks are distorted, is derived by integrating a fraction of the area, the fraction being a function of the peaks value and of the assumed mathematical form of the curve. The curve is assumed to be of e.g. Lorenzian or Gaussian form, so that, knowing this, a measured area PVSR, Fig. 4, may be multiplied by an appropriate factor to obtain the whole area under the curve. The method assumes that the value of the peak is unknown, and assumes an arbitrary value of RS/VP, different values of this ratio being associated with corresponding different values of multiplication factor (a table is given for Lorenzian curves). A minimum acceptable value of RS/VP may be obtained from a test run in which the ratio is decreased until the results of the integration show significant departure from a mean value. Clearly, the smaller the value of RS/VP, the more accurate the integration. The output of the scanning device may be time-dependent and may be in terms of frequency. Alternatively, the output of a curvetracer or XY recorder may be used. This output is differentiated and the integration started as the differentiated signal passes through zero, i.e. at the peak value of the trace. It is terminated as the trace assumes the value RS, this being set upon a potentiometer across which a signal corresponding to the peak value is imposed. The potentiometer is ganged to a variable operational amplifier the gain of which determines the multiplying factor.

Title: Heterocyclic sulphonamides
Inventor: SLACK RONALD
Filed: 1956-01-18
Abstract: The invention comprises a 1 : 2 : 3-thiadiazole compound of the formula <FORM:0806812/IV (b)/1> and amine and alkali metal and alkaline earth metal salts and ortho-carboxy benzoyl and b -carboxy propionyl derivatives thereof, and derivatives of the compound containing in the 5-position a lower alkyl group.  The compounds are made by usual methods for the preparation of N1-heterocyclic derivatives of sulphanilamide, for example by reacting a benzenesulphonyl halide bearing a substituent convertible to an amino group (such as an acylamino, alkoxycarbonylamino, carbonamide or nitro group) in the para position, with a 4-aminothiadiazole followed, if necessary, by conversion of the para substituent into an amino group or a salt or acyl derivative thereof.  In examples: (1) 4-amino-5-methyl-1 : 2 : 3-thiadiazole is treated with p-acetamidobenzene sulphonyl chloride and the resulting 4-p-acetamidobenzenesulphonamido - 5 - methyl - 1 : 2 : 3 - thiadiazole is hydrolysed to give 4-sulphanilamido - 5 - methyl - 1 : 2 : 3 - thiadiazole; (2) 4-amino-1 : 2 : 3-thiadiazole is treated as in (1) to give 4 - p - acetamidobenzenesulphonamido - 1 : 2 : 3-thiadiazole and 4 - sulphanilamido - 1 : 2 : 3-thiadiazole; and (3)-(6) the product of (2) is converted into its N4-b -carboxypropionyl and N4-o-carboxybenzoyl derivatives and into its potassium and triethylamine salts.  4 - Amino - 5 - methyl - 1 : 2 : 3 - thiadiazole is made by treating ethyl 5-methyl-1 : 2 : 3-thiadiazole-4-carboxylate with hydrazine to give 5 - methyl - 1 : 2 : 3 - thiadiazole - 4 - carboxyhydrazide, treating with nitrous acid to give the 4-carboxyazide and decomposing this by heat and hydrochloric acid to give the amine.  Similarly 4-amino-1 : 2 : 3-thiadiazole is prepared from 1 : 2 : 3 - thiadiazole - 4 - carboxylic acid via the acid chloride, the carboxyhydrazide and carboxyazide.

Filed: 1936-01-20
Abstract: 468,293. Conveyers. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Jan. 20, 1936, No. 1781. [Class 78 (i)] [Also in Group XIII] Apparatus for drying small masses of cut tobacco or like loose substances, for example, tea, comprises a rotatable drying chamber having one or more heated surfaces therein, a movable member arranged to extend through and to reciprocate in the chamber to convey the masses therethrough and to be rotatable therewith, the movable member supporting the small masses whilst moving in one direction and being inverted before moving in the opposite direction during which latter movement the small masses are supported by the fixed walls of the chamber, and means to feed the small masses in succession to the movable member. In the construction shown, slices of tobacco cut by a machine 12 are conveyed on an endless conveyer 8 to a drying apparatus 9. The apparatus comprises several drying chambers 13 connected to two discs 14, 15 rotatable about a common axis. The discs are driven in timed relationship with the cutting machine 12 and a cooling machine 11. The tobacco in small masses is delivered to an oscillating shoot 16, by means of which trough-like members 17 receive each a small mass of tobacco. Each member 17 is moved into the drying apparatus by a cam 18 as the apparatus rotates. Owing to the rotation of the apparatus the member 17 becomes inverted and discharges the tobacco into the associated drying chamber. Thereafter the member 17 is moved by a cam back into position for receiving further tobacco. As the apparatus rotates the tobacco masses are displaced transversely within the drying chambers 13, and are finally delivered on a conveyer 10. The chambers 13 are heated by electrical heating elements 21 of U-shape which are connected in series. The conveyer 10 carries the masses of tobacco to a cooling apparatus 11 through which they are conveyed in a similar manner to that in the drying apparatus. The chambers in the apparatus 11 are cooled by blowing air around the chambers, or by means of water jackets arranged about the chambers. Specification 446,221 is referred to.
