Abstract: 240,160. Bertram, O. Sept. 17, 1924, [Convention date]. Dough-dividing machines; rolling machines.- In dough dividing and kneading machines wherein, after separation of the dough, the device is given a whirling movement, such movement is produced by an eccentric located centrally of the machine; further, the eccentric drive is operated through a hand lever which also operates the compressor and dividing knife. As shown, the machine comprises a fixed table 2 supporting the dough pan 6, surmounted by a yoke 3 secured by bolts 4, 5 and supporting the presser 7 and dividing knife 8. The knife is carried by a sleeve 11 furnished with arms 19 forming guides for bolts 21 connected to the ring 9 surrounding the knives. A segmental rack 37, operable by a hand lever 59, engages a rack bar 38 connected to the sleeve 11. The presser 7 is carried by a sleeve 28 and is connected to the sleeve 11 by a latch 10 which may be disengaged by a treadle-operated rod 14 engaging an arm 13. A spring ring 22 above the arms 19 is formed with apertures to pass the bolts 21, such apertures having reduced portions to engage reduced portions 25 on the bolts. A sleeve 29 surrounding the sleeve 28 is furnished with arms 30 terminating in bearings 31 and is surrounded by a sleeve 34 eccentrically disposed on a gear 35 meshing with a gear 43 on a shaft 44 adapted to be driven through a clutch 48 controlled by a lever 49. Pins 57, 58 on a bolt 54 carrying the gear 37 engage a stop 56 on the forked end of a link 52 connected to the lever 49. In operation, a pan 6 of dough is placed in position and the ring 9 dropped by turning the ring 22. The lever 59 is then depressed to flatten the dough, after which the latch 10 is released and the knife descends until the ring 22 re-engages the portions 25. Further movement of the lever 59 closes the clutch 47 to impart the whirling movement through this eccentric sleeve 29.

[Class 38 (iv)] [Also in Groups XL (a) and XL (c)] In a pulse generator a capacitor is periodically charged from an A.C. or D.C. source via a switch and is periodically discharged into an inductor via a pair of switches connected so that current can flow through them in either direction. The inductor and capacitor forming a resonant circuit at the pulse repetition frequency. Fig. 1 shows a circuit in which capacitor C is periodically charged from the A.C. source U1 via thyratrons T3, T4 and is periodically connected via thyratrons T1, T2 to the inductive load L. One charging thyratron only may be used, Fig. 1a (not shown), or the charging and discharging thyratron may be connected in parallel, Fig. 2 (not shown). In a modification shown in Fig. 3, the same pair of thyratrons serve for both charging and discharging of capacitor C. An auxiliary capacitor C1 being first charged from the A.C. supply U1 and then transferring its charge to capacitor C. The auxiliary inductor L1 compensates in part for the capacitive loading of the A.C. supply. The thyratrons may be replaced by triggered spark gaps, rotating switches or oscillatory contacts. The circuit may be used in a magnetic conduction accelerator for accelerating electrons in an eddy current field (see Group XL (a)).

Title: Improvements in control mechanism for rotatable spindles
IPC: H03J1/14
Filed: 1925-09-19
Abstract: 263,519. Sutton, G. J. Sept. 19, 1925. Variable-speed epicyclic geanring.-Coarse and fine adjustment mechanism for rotary spindles comprises a dished member flexibly mounted on the spindle and means for tilting or rolling the dished member along a different circumferential path from its own on a fixed plane surface. As applied to a condenser. Fig. 1, a dial member 3 is flexibly coupled to the spindle 2 by a resilient washer or diaphragm 1, the outer periphery of which is secured to the member 3. A vernier knob 7 is provided with a ball race 8 and a single ball 9 is located in the race between the members 3, 7. To obtain fine adjustment the knob 7 is given a slight thrust which tilts the dial 3 and causes its flange 4 to make point contact with the panel 10, rotation of the knob 7 producing a rolling of the dial on the panel and rotation of the point contact around a circular path having a diameter less than that of the dial. The rim of the flange 4 or the surface of the panel or both may have friction surfaces or they may be toothed in which case one member has one or two teeth more than the other. Means may be provided for varying the distance between the dial and the panel and thus permitting variation of the slow speed drive. Fig. 3 shows a form of reduction ratio being effected by separating the cup-shaped member 5 from the plane surface 20 to a greater or lesser extent by means of a nut 11. The rim of the member 5 and the surface 20 in contact therewith may be constructed to give a friction or toothed drive. By forcing the member 5 out of contact with the plane surface a one to one transmission speed may be effected.

Title: Improvements in and relating to derivatives of 3-(4-hydroxyphenyl)-3-(4-hydroxy-methyl-phenyl)-oxindole
IPC: C07D209/34
Filed: 1952-09-18
Abstract: The invention comprises derivatives of 3-(41-hydroxyphenyl) - 3 - (311 - aminomethyl - 411 - hydroxyphenyl)-oxindole of the general formula <FORM:0723946/IV (b)/1> wherein R1 represents hydrogen or the acetyl group, R2 represents an alkyl radical containing from 2 to 6 carbon atoms or the cyclohexyl radical and R3 represents hydrogen or an alkyl radical with at most 2 carbon atoms.  Such compounds are obtained by condensing a compound of the formula <FORM:0723946/IV (b)/2> with an N-hydroxymethyl amide of the general formula HO-CH2-NH-COCH(R3)-OR2 and if desired, acetylating those condensation products with a free hydroxyl group OR1.  Zinc chloride in glacial acetic acid, concentrated sulphuric acid or alcoholic hydrochloric acid may be used as condensing agents.  In example (1) 3 : 3 - bis - (41 - hydroxyphenyl) - oxindole and N-hydroxymethyl-n-butoxy acetamide are reacted to give 3-(41-hydroxyphenyl)-3-(311-n-butoxy acetylamino methyl - 411 - hydroxy - phenyl)-oxindole which on reaction with acetic anhydride gives the corresponding di-acetoxy derivative.  Similarly prepared are (2) 3-(41-hydroxyphenyl) - 3 - (311 - cyclohexyloxy - acetaminomethyl - 411 - hydroxyphenyl) - oxindole and its di-acetyl derivative; (3) 3-(41-hydroxyphenyl) - 3 - [311 - (a  - n - butoxypro - pionylaminomethyl) - 411 - hydroxyphenyl] - oxindole; (4) 3 - (41 - hydroxyphenyl) - [311 - (a - ethoxybutyrylamino - methyl) - 411 - hydroxy - phenyl]-oxindole. Similarly obtained are 3-(41-hydroxyphenyl) - 3 - (311 - acylaminomethyl - 411 - hydroxyphenyl) - oxindoles in which the acyl radicals are n - propoxyacetyl, iso - butoxyacetyl, isoamyloxyacetyl, n - hexyloxy - acetyl, a  - ethoxypropionyl, a  - n - propoxypro - pionyl, a  - isoamyl - oxypropionyl, a  - n - pro - poxybutyryl, a  - n - butoxy - butyryl and a  - isoamyloxybutyryl radicals respectively.  The N-hydroxymethylamides are obtained by reacting aqueous formaldehyde with the corresponding a -alkoxy fatty acid amides. N-Hydroxymethyl - a  - n - butoxy - propionic acid amide is obtained by reacting n-butanol with a -bromopropionic acid to give a -n-butoxypropionic acid which is converted to its amide via the acid chloride, the amide then being reacted with aqueous formaldehyde. The amide can also be prepared by reacting a -chlorethylbutyl ether with cuprous cyanide and hydrolysing the nitrile produced. N-Hydroxymethyl-a -ethoxy-butyric acid amide is produced from a  - ethoxybutyric acid amide, obtained analagously to a -n-butoxy-propionic acid amide or from a -ethoxy butyric acid ethyl ester and alcoholic ammonia.

Abstract: 1364799 FET switching circuits INTERNATIONAL BUSINESS MACHINES CORP 19 May 1972 [15 June 1971] 23557/72 Heading H3T A F.E.T. R2 which charges CN2 when its gate voltage is high in response to the INPUT (to Q3) is prevented from erroneously turning on (due to # 2  and interelectrode capacitance between R1, R2 &c., causing its gate 35 to go high when the INPUT requires it to be low) by means of a clamping circuit such as F.E.T.s A, B which hold gate 35 to the low level of # 3  in # 2  time, the INPUT also being isolated during this time such as by inverter stage 32. When the INPUT is low, inverters 31, 32 cause node 41 to be low to keep R2 off, and inverter 33 applies a high level to gate 38 of R3 to turn it on, thus discharging the load capacitance CN2. The high level at gate 38 also turns on F.E.T. B and in # 2  time F.E.T. A turns on thus connecting R2 gate 35 to # 3  which is low at this time. If the INPUT is high, node 41 is high and R2 turns on; R3 is held off despite the possible interelectrode capacitance charging of its gate 38, by F.E.T. C which is on in # 1  time and Q7 which is on due to the high level at node 41, and subsequently by Q8 in # 2  time and again Q7, the 94 line being low in # 1 , # 2  times. In a simpler embodiment (Fig. 2, not shown) the gate (18) of the input F.E.T. (L3) of an inverter (2) driving the load CN2, is clamped to # 3  in 94 time by a F.E.T. or other switch (21). In this case the INPUT is isolated by a delay circuit, which again ensures that a change in INPUT during a clock cycle is ineffective until the next cycle.
