Title: An improved drilling and tapping machine
IPC: B23B39/16
Filed: 1935-02-25
Abstract: 454,371. Drilling and tapping machines for spoke nipples &c. POLLARD & CO., Ltd., F., and COSFORD, J. J., St. Saviours Road East, Leicester. Feb. 25, 1935, No. 5936. [Classes 83 (ii) and 83 (iii)] A multi-spindle automatic drilling and tapping machine of the type comprising the combination of a workholding table, a hopper for supplying workpieces, a drilling head carrying drilling and tapping spindles, means for effecting intermittent relative motion between the work-holder and the head and for effecting relative movement of the head towards and away from the work-table with means for reversing the tapping spindles, is characterized in that the work-holder or table is inclined to the horizontal and in that the machine is arranged to operate upon headed work-pieces but at the non-headed ends thereof, means being provided for removing the work-pieces from the supply in the hopper by their heads and for inverting them before they reach the work-holder. An electric motor 47, Fig. 1, drives the tool spindles through a splined shaft 44, permitting movement of the cam-fed spindle head 21 towards and away from the work table 17, while rotation of the cam drum 23 is effected by the same driving motor through pick-off gears, housed within the removable cover 39, and a yielding connection adapted to slip upon overload of the spindles. The latter are arranged in three sets of two, two sets for drilling and one for tapping in the case of operations on a spoke-nipple, Fig. 8. The nipples are fed two at a time to the work table where they are automatically clamped by levers such as 70, Fig. 1, the table being indexed twice the circumferential distance between a pair of nipples to feed the latter to the next pair of tools. Feeding means for the nipples comprise a hopper 20 within which a vertically reciprocating member 110 lifts nipples on its upper surface which if properly positioned, are allowed to pass by a roller 111 down a pair of inclined guides 112. Transverse pins 113, 114 on a reciprocating crossbeam 115, Fig. 5, allow the nipples to pass one at a time in each guide so that two nipples pass down the shoots 118 to be fed to adjacent recesses in the work table by plungers 119. Transverse pins 117. placed in the paths of the nipples turn these over before they fall down the shoot thus while sliding down the guides head uppermost they are fed into the work table with their unheaded ends uppermost. The tapping spindles 61, Fig. 3, are driven at a slow tapping speed by gearing 63 but on reversal of the spindle head and the commencement of a quick return thereof the tapping spindles lag behind the movement of the housing, compressing the springs 61 and subsequently engaging a high speed reverse drive through dog teeth on the collar 65 engaging teeth on the ends of spring-pressed plungers 66. Specifications 28210/97, [Class 83], and 301,371, [Class 83 (iii)], are referred to.

Abstract: 588,905. Buildings. McALPINE, Sir M. March 10, 1945, No. 6031. [Class 20 (iv)] The walls of buildings are built from storeyhigh rectangular elements each comprising a covered wooden frame having a longitudinal groove 32 along its lower edge which engages a tongue 22 upstanding from the foundation or footing 21. After the first element has been positioned the second element is placed on blades 44 out of contact with the damn-course 43 so as to avoid the damage thereto which would be caused if the elements were slid into position. After the groove 32 of the second element has been centred over the tongue 22 and the. second element moved to abut against the first the second element is levered up somewhat to enable the blades 44 to be removed and to permit studs 41 projecting from one vertical edge of the second element to rise in the large upper apertures of key-hole slots formed in the vertical edge of the adjacent element in which the studs have already engaged. The second element is now dropped and the studs pass into the restricted portions of the key-hole slots thereby locking the elements together. Additional security is given by co-acting ribs 33 and grooves 34. The outside of the frame elements may comprise steel or aluminium sheets 29 with joint-sealing strips 35 and a heat-insulating layer 30 of glass silk may be inserted in the elements. A second storey and roof may be added.

IPC: H03M1/00
Filed: 1967-02-10
Abstract: 1,156,613. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 10 Feb., 1967, No. 6509/67. Heading G4H. An analogue-to-digital converter comprises an array of multi-stable devices D1-Dn and a plurality of weighted interconnections 1R1, 1R2 &c., by which the devices are coupled to one another and to the analogue-input, the interconnections being such that the input to each device D1-Dn is a combination of the analogue input and a weighted function of each output from all the other devices, the weights being such that each stable state of the array corresponds to a prescribed digital representation of the analogue input. The output a 1 -a n  from each device D1-Dn is connected by weighted interconnections to all the other outputs, and the input X is connected through weighted interconnections to the inputs of each device D1-Dn. The devices are binary discriminators, i.e. the output is " 0 " or " 1 " depending upon the sign of the input. The interconnections XR1, nR1, 2R1 and 1R1 compare the weighted input X with the sum of the weighted binary values a 1 -a n  and the difference is applied to the input X 1  of the discriminator D1. The inputs X 2 -X n  are derived similarly. The discriminators may be given different response times so that they do not operate simultaneously. The discriminators respond in a predetermined sequence so that the final state gives a coded digital representation of the input signal. Instead of having separate feed-back circuits to each discriminator, there may be single feed-back loop having a signal equal to the difference between the input and the sum of the weighted outputs from the discriminators. Each discriminator has a feed back loop whereby the complement of the output is applied to the input, the input value being the difference between the common feedback signal and the complement value.
